Mesothelioma Diagnosis

Mesothelioma patients are typically diagnosed within three to six months of their first visit to a doctor with complaints about breathing problems or chest and abdominal pain. The first step involved in diagnosis is providing a full and accurate medical history to your doctor, including details about current and past health concerns, as well as the types of symptoms you are currently experiencing.

It is important to mention any possible exposure to asbestos. Without revealing this fact, your doctor may not consider asbestos-related diseases in his or her examination. Next, patients will undergo a physical examination where a doctor will examine causes for any types of symptoms being displayed. In most cases, the doctor’s next step will be to recommend further testing.
Mesothelioma Diagnostic Tests

If your doctor suspects an asbestos-related disease such as mesothelioma, the next step in the diagnostic process includes testing to confirm the presence of mesothelioma, determine the location, size and type of cancer involved, and determine whether the asbestos cancer has spread to other parts of the body. This will often involve imaging tests such as:

* Chest X-ray: This is the most commonly used imaging test for the diagnosis of mesothelioma. Almost all diagnoses will involve an X-ray, but a more sophisticated test may follow.
* CT Scan: This is an X-ray-like procedure in which several X-ray pictures are taken and combined with a computer to produce a detailed image of body tissues. If you undergo a CT scan, you may be given an intravenous injection of dye that helps produce more detailed images.
* PET Scan: A glucose solution is administered through intravenous injection and a scanner is used to spot deposits of cancer cells. Malignant cells take up and use sugars more quickly than normal cells, so they can be easily distinguished using this procedure.
* MRI Scan: A combination of radio waves and a strong magnetic field is used to create detailed three-dimensional images that can be carefully examined by a radiologist.

Fluid and Tissue Tests

These tests, also known as biopsy tests, involve collecting small samples of fluid or tissue and checking them for the presence of cancer cells. Such tests include:

* Fine Needle Aspiration: Mesothelioma cancers cause fluid to build up in affected locations, such as in the pleural membrane?. During a fine needle aspiration, a doctor will remove a fluid sample using a very long, thin and hollow needle.
* Thoracoscopy: Thoracoscopy is used in cases where pleural or pericardial mesothelioma is suspected. During this procedure, a very small incision is made in the chest wall and a sample of tissue is removed.
* Bronchoscopy and Laparoscopy: These procedures are similar to the thoracoscopy, but are performed on different parts of the body. The bronchoscopy is used to view the trachea and airway, while the laparoscopy is used to remove samples of peritoneal tissue.
* Mediastinoscopy: This procedure is used to view lymph nodes in the chest and neck, to determine if cancer has spread from its point of origin.

Mesothelioma Disease

When a patient learns of a mesothelioma diagnosis, confusion is often one of the first emotions experienced. What exactly is mesothelioma? Is it a disease? A virus? Mesothelioma is actually a rare type of cancer. When people refer to mesothelioma disease, they are actually referring to mesothelioma cancer. Mesothelioma develops in the mesothelium, the membrane that surrounds several body cavities. The mesothelium is comprised of mesothelial cells, which become abnormal and divide uncontrollably if mesothelioma is present.

Four different types of mesothelioma exist. Pleural mesothelioma is the most common form of the cancer and develops in the lining of the lungs, known as the pleura. Peritoneal mesothelioma affects the lining of the abdomen, known as the peritoneum. Pericardial mesothelioma is very rare, as approximately 200 cases have been reported internationally. Pericardial mesothelioma develops in the pericardium, the membrane that surrounds the heart and protects the organ. Testicular mesothelioma is the rarest form of mesothelioma and develops in the lining surrounding the testicles, known as the tunica vaginalis.

Approximately 2,000 to 3,000 people are diagnosed with mesothelioma annually in the United States. Many patients are not diagnosed with the cancer until it has reached later developmental stages since it may take 20 to 50 years for a patient to demonstrate symptoms of mesothelioma. The cancer is caused almost exclusively by asbestos exposure and it often takes decades for a patient to express mesothelioma symptoms from the time initial asbestos exposure occurred.
Mesothelioma Symptoms

Diagnosis can be difficult because symptoms often resemble more common illnesses and are non-specific. Patients are often unaware of the severity of their condition until they are diagnosed with mesothelioma. A patient with peritoneal mesothelioma may express symptoms such as a persistent dry or raspy cough, difficulty breathing and swallowing, night sweats and fever, among others. Pericardial mesothelioma patients may complain of swelling or pain in the abdomen, fatigue, nausea, night sweats or the appearance of lumps under the skin on the abdomen. A patient with pericardial mesothelioma may experience heart palpitations or irregular heartbeat, chest pain, difficult breathing, fever and fatigue. Testicular mesothelioma symptoms have been confined to the appearance of testicular lumps.
Mesothelioma Diagnosis

Once a patient demonstrates unusual symptoms and visits a doctor, a medical review and physical examination often follow. Typically, further testing will be needed and an x-ray will likely be requested to pinpoint the location of the cancer and determine whether or not it has spread to other areas of the body. Additional imaging tests such as a CT scan, PET scan or MRI are often recommended for a more detailed image of the cancer. A fluid and tissue test, known as a biopsy is then typically conducted to collect a sample of fluid or tissue to test for the presence of cancerous cells. A pathologist generally examines the sample to determine whether or not mesothelioma is present.
Mesothelioma Treatment

After diagnosis, patients and their loved ones are often anxious to do everything possible to fight mesothelioma. This may involve several different treatment options. The most common treatments mesothelioma patients utilize include surgery, chemotherapy and radiation.  Though a cure for mesothelioma does not currently exist, many patients undergo several treatments for relief from symptoms to improve the quality of life. Patients may also experience relief through experimental options and treatments available through clinical trials and alternative therapies.

Mesothelioma

Mesothelioma is a rare type of cancer that typically affects the lining of the lungs, heart and abdomen.Mesothelioma is a rare cancer that can develop in the membrane that lines the lungs, called the mesothelium.
Approximately 2,000 to 3,000 cases of mesothelioma are diagnosed each year in the United States, comprising around 3 percent of all cancer diagnoses. This cancer occurs about four times more frequently in men than in women and all forms of mesothelioma, except for benign mesothelioma, are invariably fatal.

The life expectancy for mesothelioma patients is generally reported as less than one year following diagnosis, however a patient’s prognosis is affected by numerous factors including how early the cancer is diagnosed and how aggressively it is treated.

Mesothelioma is an aggressive cancer that affects the mesothelium? causing cells in the membrane to become cancerous and divide rapidly. This causes the thickening of the membrane, fluid buildup and the formation of tumors. This can result in difficulty breathing, nausea, fatigue and a myriad of other concerns.

Mesothelioma Causes

Mesothelioma is caused by asbestos exposure which occurs when fibers are inhaled or ingested into the body and become lodged in body cavities, causing inflammation or infection. Asbestos is a naturally-occurring fibrous substance that was widely used in the 20th century in a number of different industries. When the public became aware of the hazards associated with the mineral, warnings were issued in the mid-1970s and use of the product began to decline.

More than 30 percent of those diagnosed with mesothelioma are veterans. Please visit the page on asbestos for additional information about the mineral.
Mesothelioma Types

There are five known types of mesothelioma. The four listed below are malignant cancers, and benign mesothelioma is a non-cancerous condition.
Mesothelioma Diagram
Once asbestos is inhaled it can effect many of the bodys different organs including the throat, lungs, stomach, heart and testicles.

Pleural Mesothelioma: This type of mesothelioma develops in the lining of the lungs, known as the pleura. It is the most common form of malignant mesothelioma, with around 70 percent of cases being pleural in origin.

Peritoneal Mesothelioma: Comprising approximately 25 percent of mesothelioma cases, this form of mesothelioma develops in the lining of the abdominal cavity, known as the peritoneal membrane.

Pericardial Mesothelioma: This form of mesothelioma develops in the lining of the heart, known as the pericardium. Approximately 5 percent of all mesothelioma cases are pericardial.

Testicular Mesothelioma: Testicular mesothelioma develops in the tunica vaginalis of the testicles and is the rarest form of the cancer.
Mesothelioma Symptoms

Symptoms of mesothelioma often do not appear for 20 to 50 years after initial exposure to asbestos occurred. Mesothelioma symptoms often resemble less-serious conditions, which can make diagnosis difficult. Below is a list of several common symptoms mesothelioma patients may experience.

Pleural Symptoms: Shortness of breath, chest pain, persistent cough, fatigue, lumps under the skin on the chest

Peritoneal Symptoms: Weight loss, abdominal pain and swelling, bowel obstruction, nausea

Pericardial Symptoms: Heart palpitations, irregular heartbeat, chest pain, difficulty breathing, night sweats

Testicular Symptoms: Painful or painless testicular lumps
Mesothelioma Diagnosis

A medical exam is the first step in diagnosing an asbestos-related illness.
The process of mesothelioma diagnosis usually begins with a review of a patient’s medical history followed by a physical examination.

If a problem is suspected, a doctor may request several diagnostic tests. These typically include medical imaging scans such as:

* X-rays
* CT scans
* PET scans
* MRI scans

A combination of these tests is often used to determine the location, size and type of the cancer. Biopsy procedures are often requested following an imaging scan to test samples of fluid and tissue for the presence of cancerous cells.
Mesothelioma Treatments

After a patient begins to demonstrate mesothelioma symptoms and a diagnosis occurs, the next step is often exploring applicable treatment options to create the best treatment plan possible. Treatment options range from surgery to chemotherapy and Asbestos.com offers mesothelioma patients and their loved ones comprehensive information about current treatment options and new developments in a complimentary informational packet available here.
There are a variety of treatment options for mesothelioma patients including radiation, chemotherapy, and surgery.

The most common mesothelioma treatments recommended by doctors for patients include surgery, chemotherapy and radiation therapy. Experimental procedures, including immunotherapy and gene therapy are also utilized by mesothelioma patients. Patients often undergo multiple treatments to combat the disease.

Experimental treatments are also available to patients who participate in a clinical trial, conducted to test up-and-coming procedures and medications.

Cancer Prevention has always been better than cure. Cancer prevention is no different. Cancerous tissue can develop in any part of the body. But largely, the media tends to focus mainly on breast and prostate cancer.

Another fatal type of cancer seen among Americans is the bladder cancer. The American Cancer Society mainly identifies four types of bladder cancers. They are urothelial carcinoma, squamous cell carcinoma, adenocarcinma, and small cell cancer. The bladder cancer is detected by recognizing symptoms such as blood in urine or excessive pain in the abdominal area.

Smoking is considered as a major cause of cancer. The American Cancer Society reports that smokers are more likely to develop cancer as compared to individuals who don’t. Therefore prevention of cancer mainly involves reducing smoking habits.

Studies also show that men are more likely to develop bladder cancer as compared to women. Apart from smoking various other factors contribute towards cancer. They include age, race and family history. Although none of the studies have found a definite cause for the disease, there is strong evidence which suggests that making changes in your lifestyle lower your risks of cancer.

Treatment of bladder cancer involves various options. There are different kinds of surgeries that are suggested which depend on the stage of your cancer. By means of surgery, a partial removal of the bladder or removal of the entire organ is performed.

Early stages of cancer can be treated by immunotherapy, chemotherapy or radiation therapy treatments. Once the treatment is begun, it is important to ensure that follow up treatments are received so that the cancer does not return at a later stage. In case there is a recurrence of cancer, there are various tests and treatments to determine the stage and severity of cancer so that an appropriate treatment can be provided.

A new treatment that is now used for cancer is the Photodynamic Therapy Test (PDT) which involves injecting a chemical into the body which clings to tumor cells in the bladder followed by the use of a laser to kill the tumor cells and eliminate the cancer.
Even with all the available treatment for cancer, preventing cancer is the best method to stay away from the deadly disease.

Biological therapy, which is also known as the immunotherapy or biotherapy is a method which makes use of the body’s immune system to fight cancer. The immune system works towards protecting and defending the body against bacteria and viruses.

These Biological therapies can boost the immune system by making cancer cells more recognizable to the immune system of the body. It also helps to change the way cancer cells grow and stops the process which changes normal cells into cancerous cells.

The human immune system includes white blood cells which are capable of fighting against cancerous cells. Major types of white blood cells include lymphocytes, B cells, T cells, natural killer cells (NK cells), monocytes and dendritic cells. These cells are circulated to every part of the human body thereby providing protection diseases including cancer.
Human cells are known to secrete two types of substances – antibodies and cytokines which respond to (harmful) substances and act as messengers respectively.

Biological response modifiers (BRMs) change the way the body’s defenses interact with cancerous cells. They include nonspecific immunomodulating agents, interferons, interleukins, colony-stimulating factors, monoclonal antibodies, cytokine therapy, and vaccines. Nonspecific immunomodulating agents stimulate the immune system, resulting in production of more cytokines and antibodies that help to fight cancer.

Interferons (IFN) improve the patient’s immune response to cancer cells. They work directly on cancer cells and slow their growth. Sometimes these interferons are also known to stimulate NK cells, T cells, and macrophages.

Interleukins (IL) are responsible to stimulate the growth and activity of many immune cells. They occur naturally in the body and simulate the growth of lymphocytes which work towards destroying cancerous cells.

Colony-stimulating factors (CSFs) are proteins that are given to patients to encourage stem cells within the bone marrow to produce more blood cells. With proper cell production, other cancer treatments can continue enabling patients to safely receive higher doses of chemotherapy.

Vaccine therapy is currently in an experimental mode. This therapy is aimed at vaccinating people before the disease develops. Though this therapy is still under development, it may go on to become one of the most sought after methods for cancer treatment.

What are the side effects of biological therapies?
Side effect to a treatment ranges from nil to mild to being very severe. It is necessary to discuss all possible side effects of treatment before the treatment begins. Some of the side effects include fever, nausea, vomiting, loss of appetite and fatigue

What is gene therapy?

Genes, which are carried on chromosomes, are the basic functional units of heredity. Genes are specific sequences of bases that encode instructions on how to make proteins. Gene therapy is a technique for correcting defective genes responsible for disease development.

Several approaches for correcting faulty genes:

• Through direct replacement.
• Through homologues recombination.
• Through selective reverse mutation.

How does gene therapy work?
A carrier molecule called a vector is used to deliver the therapeutic gene to the patient’s target cells. The most common vector is a virus that has been genetically altered to carry DNA.
Target cells are infected with this viral vector. The vector then unloads the therapeutic gene into the target cell. This restores the target cell to normal state.

Different viruses used as gene therapy vectors:

• Retroviruses: Human immunodeficiency virus (HIV) is a retrovirus.
• Adenoviruses: The virus that causes the common cold is an adenovirus.
• Adeno-associated viruses
• Herpes simplex viruses: A human pathogen that causes cold sores is HSV.

There are several nonviral options for gene delivery. . The simplest method is the direct introduction of therapeutic DNA into target cells. It can also be done through chemical means . Researchers also are experimenting with introducing a 47th (artificial human) chromosome into target cells.

What is the current status of gene therapy research?
The Food and Drug Administration (FDA) has not yet approved any human gene therapy product for sale .Current gene therapy is experimental and has not proven very successful in clinical trials. In 1999, gene therapy suffered a major setback with the death of 18-year-old Jesse Gelsinger.

What factors have kept gene therapy from becoming an effective treatment for genetic disease?

• Short-lived nature: .Problems with therapeutic DNA and the rapidly dividing cells prevent gene therapy from achieving any long-term benefits.
• Immune response: The immune system’s response to therapeutic DNA is a major risk for genetherapy.
• Problems with viral vectors: They present problems like: toxicity, immune responses, etc.
• Multigene disorders: Multigene disorders such as heart disease, diabetes are difficult to treat effectively using gene therapy.

The transplantation of hematopoietic stem cells a cure for cancer really is nowadays established as a therapy for a wide variety of congenital or even acquired severe disorders of the hematopoietic system as well as for chemo or even radio sensitive malignancies.

Stem cell storage can be done using a stem cell bank or cord blood bank.
The transplantation includes autologous and allogeneic transplants of hematopoietic stem cells from bone marrow or cord blood. . Donors for allogeneic transplants can be identical siblings or other family members.

Over the last decade, a lot has been experienced by different companies. Convincing results and reduction in transplant related mortality have opened up new indications and increased patient age which led to an expansion in Europe.
This is best illustrated by the annual activity surveys of the European group for blood and marrow transplantation which was introduced in the nineties. A total of over four thousand transplants were reported and all bone marrow derived. Major changes have taken place and stem cell source has been expanded .This rapid development of the European group has not remained unchallenged. Major concerns have been issued concerning the value of autologous cells which has decreased.
The annual survey provides a tool to monitor changes in activity for individual indications and allows scientists to observe trends in participating European countries.

In January 2000, all the members of the group were requested to report by questionnaire. The same questionnaire was used as in 1998. Identical information was sought from non members who were known to investigators to be performing transplants. Such information was given to the activity survey office by national organizations, neighboring teams or hospital administrators.

Radiotherapy is the use of high energy x-rays and similar rays to treat disease. Radiotherapy is used as a treatment for over 100 years ago. Many people with cancer have radiotherapy as part of their treatment either external radiotherapy or internal radiotherapy. Radiotherapy works by destroying the cancer cells in the treated area .It might damage the normal cells but the side effects are very mild.

About your treatment

External radiotherapy is normally given as a daily treatment (Monday-Friday) in the radiotherapy department. Each treatment is called a fraction.

Giving the treatment in fractions ensures that less damage is done to normal cells.
The number of treatments you have depends on several factors like:

• Your general health.
• The type of cancer being treated
• Whether you have or are going to have surgery, chemotherapy, etc.

External radiotherapy is perfectly safe for you as it does not make you radioactive.

Internal radiotherapy is used to treat cancers mainly in the head, neck or the skin.

Treatment is given in one of two ways:

• By putting solid radioactive material inside the tumour (brachytherapy).
• By using a radioactive liquid, which is given either as a drink or as an injection (radioisotope treatment).

In this treatment you may have to stay in hospital for a few days and special precautions have to be taken.

General side effects of external radiotherapy

As stated earlier, side effects of radiotherapy are mild.There have been huge improvements in radiotherapy and severe side effects are very rare.

As radiotherapy affects people in different ways, it’s difficult to predict exactly how you will react to your treatment. Before you start, the staff will discuss with you any side effects, and give tips on how to deal with them.

Most side effects of radiotherapy disappear gradually after treatment. For some people however, they may continue for a few weeks.

Some common side effects:

1. Tiredness
2. Skin disease ( during external radiotherapy)
3. Hair loss
4. Change in your blood ( bone marrow)

Chemotherapy drugs are used to halt the division and reproduction of cancer cells, but can also damage some of the more sensitive normal cells, such as bone marrow. The cancer cells cannot survive after attack by chemotherapy drugs.

Each chemotherapy drugs has a unique mode of killing the cancer cells. Certain cancers, prostate cancer, for instance, develop resistance to a single chemotherapy agent and so, a combination of drugs may be more successful. . There are over 200 drugs used in as many as 50 combinations.

Typically, chemotherapy is administered intravenously. Treatments are given in a series, usually once every two or three weeks. This allows a ‘rest period’ for the patient, recovering from side effects. Directly after chemotherapy, an anti-sickness medication is given to lessen the unpleasant side effects.

Chemotherapy has the potential to completely cure the disease by destroying all the cancer cells. Sometimes a course of treatment is extended; this is to eliminate possible cancer cells that are too small for detection.

Strategies for Chemotherapy use
Chemotherapy is used pre-operatively to shrink the tumor, making surgery less invasive. In a post-operative treatment, chemotherapy is almost used as a preventive, to kill any cells which are too small for removal during surgery. Some cancers cannot be completely removed during surgery. In this case, chemotherapy is used, not as a cure, but to reduce the tumor.
In cooperation with radiation, chemotherapy works together to more quickly eradicate cancer. Bone marrow transplants are indicated when using high-dose chemotherapy. A major side effect of the high-dose therapy is the destruction of bone marrow. Stem cells are used to replace the bone marrow.

Mechanisms of Cancer Cell Destruction
As stated earlier, chemotherapy drugs were used on unique areas of the cancer cell. The older drugs cause unpleasant side effect but the new drugs target the outer cell wall of the cancer cell and the reproductive mechanism of the cell.
Most often, chemotherapy drugs are used in combination with each other, surgery, radiation, hormone therapy. Since each person and cancer is unique, the treatment must be unique as well.

Did you know that cancer is treatable? Many of you reading must be aware of that, but do you know how many possible treatments are possible for cancer?

In the 21^st Century, cancer treatment is very much possible.  The doctors have researched and invented and discovered at least seven ways to treat this hazardous disease.

These are the best seven ways adopted by doctors to cure cancer:

1. Surgery
2. Chemotherapy
3. Radiotherapy
4. Bone marrow and stem cell transplants
5. Biological therapy
6. Hormone therapy
7. Gene therapy
   
   

Many of you must be waiting to know what all these ways are. Well just sit and relax because I am going to explain you everything from AtoZ.

Surgery:

Surgery is a very good option to cure cancer only if the cancer cells have not spread to other areas and are contained to one tissue only. This treatment is very local and doctors prefer before taking any other options.

Similarly, if you are suffering from blood cancer or lymphoma cancer then surgery is not the best option as the cancer cells will be found in other various parts of the body.

If you are told to do a surgery it may well cure the cancer. This will depend on

• Whether the cancer can be completely removed
• Whether a border of healthy tissue, free of cancer cells, is removed with the cancer
• Whether the cancer has already spread before the surgery

Problems associated with surgery.

Though surgery can remove the cancer safely for a person’s body, it may also have a few setbacks. Like

• Pain
• Wound infection
• Chest infection
• Blood clots
• Fluid collection around the wound

Also, antibiotics will be given so that the cancer may not occur again in the same area of the body.
