Mesothelioma is a malignant tumor of the mesothelium caused by exposure to asbestos fibers. Because mesothelioma is very hard to control and is known for its late onset of symptoms, the U.S. National Cancer Institute (NCI) is sponsoring clinical trials that are used to find new treatments and efficient ways to use current treatments.

The most popular method is radiation therapy, also called radiotherapy, which involves using high-energy rays to kill cancer cells and shrink tumors. Radiotherapy affects only the treated area during the treatment. The radiation may come from a machine that produces radiation through thin plastic tubes into the area where the cancer cells are found.

A common treatment for the disease is surgery that involves the removal of part of the lining of the chest or abdomen and some of the tissue around it. In case of pleural cancer, a lung may be removed in an operation called a pneumonectomy. In few cases, a part of the diaphragm, the muscle below the lungs that helps with breathing, is also removed.

Anti-cancer drugs are used to kill these malignant cells throughout the body. This is known as chemotherapy and involves injecting the drug into a vein (intravenous or IV). Currently, doctors are also studying the effectiveness of putting chemotherapy directly into the chest or abdomen.

There are various procedures that are used for the treatment of mesothelioma. Generally, the treatment type depends on the location of the cancer, the stage of the disease, the patient’s age, and general health. Pleural effusion that is caused by heart failure or infection can usually be resolved by directing treatment, however, when testing has realized no diagnosis and fluid continues to build or recur, doctors may recommend chest tube drainage and chemical pleurodesis. Chemical pleurodesis is a technique in which a sclerosing agent is used in treatment. It is used to abrade the pleural surfaces producing an adhesion between the parietal and visceral pleurae, which prevents from further effusion by eliminating the space in pleura. Talc is considered the most effective agent for pleurodesis.

Future study of colorectal cancer will refine our understanding of the genetics of the disease. This in turn will lead to earlier identification and treatment of high-risk persons. The future may possibly bring the use of genetic interventions to interrupt the adenoma-carcinoma sequence.

Increased awareness of colorectal cancer by the public and by private insurers, government agencies, and medical personnel will result in better use of available screening techniques. Development of preventive drug strategies against colorectal cancer, particularly with drugs that reduce polyp formation or prevent polyp progression to cancer, promises to be a fruitful field of endeavor.

There is ample reason to expect refinement of diagnostic and staging tests for the disease, perfection of surgical and nonsurgical techniques for treatment of large bowel cancer and its complications, and improving chemotherapeutic treatment by means of more effective and less toxic drugs.

A number of molecular markers for colorectal cancer can be measured but it is not yet clear that they have prognostic value or therapeutic implications. Measures of DNA synthesis or cell division are of uncertain value as clinical decision-making tools. Measurement of thymidilate synthase activity in colorectal cancer tissue is one of several markers under investigation as a prognostic indicator.

This could be useful in making decisions regarding the use of adjuvant chemotherapy for certain patients, especially those with stage II or B tumors. Another goal would be to collect a set of markers for cancer risk for an individual who has adenomatous polyps. Presumably, such testing could reflect exposure to colon carcinogens and help define the outlook for an individual. This in turn could narrow the prospective use of screening and diagnostic procedures such as colonoscopy.

Techniques to identify micrometastases in lymph node tissue are in development. These include special stains for cytokeratin, which can identify small clusters or single malignant cells in lymph node tissue. Another method uses a technique known as PCR for detection of CEA in resected lymph nodes. PCR is a technique which permits rapid reproduction of large quantities of short segments of DNA or RNA.

Other techniques include the identification in lymph node tissue of oncogene, or tumor suppressor gene mutations, which occur in the primary tumor. Such techniques may be of use in reclassifying patients whose lesions are stages as II or B by conventional means and in selecting them for potentially life-saving adjuvant chemotherapy. Large clinical trials will be needed to determine if identification of micrometastases by these methods indeed leads to more appropriate treatment and improved progress.

Expression of the enzyme COX-2 by colorectal cancers is highly variable. Greater expressions of COX-2 by tumors are associated with lymph node metastasis, advanced stage of cancer, and poorer long-term outlook for patients. Thus, there could be potential future application of this test as a means of staging and prognostication.

It has been proved that asbestos is responsible for a host of deadly diseases, including cancer. Settlements worth billions have been given in asbestos litigation; settlements worth billions more are pending in various American courts.

The purpose of asbestos settlements is to help the victim of asbestos related diseases with money to cover medical expenses. In worse cases, it was meant as a compensation for the loss of income over the years, and the potential earning capacity of an individual.

The government has set up regulations that limits asbestos exposure with the permissible limit for exposure being 0.1 fibers per cubic centimeter for an eight hour workday. For every 30 minutes of work period, fibre exposure should fall below 1.0 fibre per cc. Statutory health protection measures such as these have been mandated.

The process of asbestos settlement puts the onus on the employer to compensate victims of asbestos related health problems. In case the company fails to adhere to these stipulated protection rules, resulting in adverse effects for its workers, the company is legally bound to pay settlement to the affected workers as compensation.

There have been numerous cases of asbestos settlements in the United States, after the awareness towards asbestos as a health hazard grew. Two of these famous cases happened in 1997 and 1999. Both these cases involved huge settlement class actions. In the end, both these settlements were overturned by the court.

There are also allegations of asbestos settlements having become a full-fledged industry, where the party benefiting the most are the attorneys, as they get a part of the settlement as fees for fighting the cases.

Do you fear breast cancer? Many women do because it is such a killer! Surprisingly, men are not immune to this disease either.

If you received a diagnosis of breast cancer just 20 years ago, your chances of being a survivor would have been much less than they are today. That’s because of the marvelous advance of medical research.

There are a lot more options available now for treating malignant tumors than were available a few years ago. And more and more women are breast cancer survivors today.

But you would like to know what your particular risks are for developing breast cancer, wouldn’t you? Although no one knows exactly who is going to get breast cancer, there are risk factors that can be taken into consideration. You can do something about some of these risk factors, and other risk factors there’s not much you can do about. — except to be on your guard.

Here are the risk factors you can control:

1. Obesity

2. Drinking alcoholic beverages

3. Smoking

4. Taking estrogen with progesterone for menopausal symptoms

5. Using birth control pills

6. Lack of exercise

7. Choosing to feed your baby with a bottle instead of breast-feeding.

The following are risk factors over which you have no control:

1. Aging

2. Breast cancer in your immediate family

3. Starting your periods before the age of 12

4. Passing through menopause after the age of 50

So as you can see, there are risks you can do something about and risks that you can’t do anything about. So why not start with what you can do? For example, choose to eat healthy foods instead of junk food. Stay away from alcoholic beverages and smoking. Exercise regularly.

For the risks you can do nothing about, you can use preventative measures. If your mother or and or another close relative had breast cancer, try to remember to schedule a yearly mammogram. And have a doctor examine your breasts once a year. Learn how to do breast exams once a month yourself and be faithful about checking your breasts on a regular basis.

To even more accurately assess your personal risk for developing breast cancer, you can take a test that will let you know if you carry a mutated gene related to breast cancer.

Why not choose to reduce your risk factors by doing all you can to protect yourself from this deadly disease?
