The US Food and Drug Administration announced that Roche Remove breast cancer from the indicated of Avastin which it own production of anti-cancer drug in December 16, 2012. The reason is that the drug lack of evidence for safety and efficacy in the treatment of breast cancer.

FDA stressed that delete an indication for Avastin does not cause the drug from the market shelves, the drug may continue for the treatment of colon, kidney, lung and brain cancer. Avastin is a novel medicine that inhibits the growth of a network of blood vessels that supply nutrients and oxygen to cancerous tissues. Axitinib is a pill taken twice daily, while Avastin is given periodically by intravenous infusion. Avastin is a laboratory-produced molecule known as a monoclonal antibody that mimics the antibodies produced by the body’s immune system to defend against harmful substances. so that FDA announced avastin side effects breast cancer suggest to stop using. Almost three years ago, Avastin was shown in a major study to significantly prolong the time patients with breast cancer remain in remission. The most serious side effects associated with Avastin, in some cases resulting in death, are gastrointestinal perforation, wound healing complications, hemorrhage, and blood clots. In addition, the F. D. A. said that 71 percent of the women who got Avastin suffered from a serious side effect, compared with 51 percent of the women who got paclitaxel along.

Radiation with surgery and chemotherapy to treat cancer, as a lifestyle. Today, solid tumors, skin cancer, breast, brain, cervical, or the format used to treat leukemia and lymphoma applied.

Radiotherapy works by DNA damage in cancer cells to spread and grow because they can not. Radiation in the tumor, even after the destruction of concern about the disease. Although the beam is directed at cancer cells, it is inevitable or normal non-cancerous tumor found in the effects of radiation caused by damage to normal cells. treatment of tumor cells are designed to maximize coverage and normal healthy cells as much as possible.

Most forms of radiation, cancer cells are able to achieve the goal of producing damage to healthy tissue surrounding the tumor attacks. adverse effects of radiotherapy are the main factors that development. Moreover, the CyberKnife treatment and proton technically advanced form of radiation on normal tissue damage caused by a little due to cancer.

effectiveness of radiotherapy, such as ginseng and radio sponsors, whey protein can improve glutathione and oil and sharks and radio sensitization, such as genistein, green tea, turmeric and hyperthermia. In general, certain medicines, dietary supplements and the use of other techniques are avoided and the improvement of side effects of radiation and the reasons for its healing, development of effective radiotherapy.

Colon cancer:Colon cancer is also called as colorectal cancer. Colon cancer is referred as malignant tumor in which there will be an unusual growth of cells inside the colon or rectum than the required rate.

Colon cancer starts from the inner lining of the large intestine, this is the common part for the occurrence of colon cancer. So removal of these colonic polyps can prevent from the occurrence of colon cancer.

During the early stages of the colon cancer, there will be no symptoms or signs. Fully developed colon cancer results in causing symptoms like rectal bleeding, weight loss, bloodstream in the stool and bowel obstruction.

Causes of colon cancer:
Age: Generally aged people will be suffering from cancer due to the presence of polyps (glands) .if the age is above 50 years, there will be more chances of getting cancer due to the increase in risk factors.

Alcohol: Taking of alcohols will reduce the performance of body immune system which causes the chances of occurring cancer disease.

Diabetes: Diabetes leads to the occurrence of colon cancer due to insulin dependency at high rate.

Diet: Diet plays an important role in defining cancer. Taking fat foods with low fiber content will definitely causes cancer. Planning proper diet menu with rich fiber foods helps in preventing cancer from occurrence.

Environment: The surroundings in which you live and work also leads many risk factors for causing cancer. So, maintain proper surroundings.

Prostate cancer: Prostate cancer is referred as malignant tumor because it is cancerous and moreover it spreads to the various organs in the body. It has metastatic characteristics. Prostate cancer occurs to the cells of prostate gland. These cancer cells have disorder in their life cycle. Prostate cancer occurs due to the unusual growth of the cells in the prostate glands without controlling limit. Mobility of these uncontrolled cells from original state to distant state causes destruction to the adjacent body tissues.

Prostate cancer is a combination of several diseases with different types of causes, symptoms and treatments. Cells are the basic unit of life, they grow and divide into more cells when the body requires them. These cells forms the tissues and then organs, they are the building blocks of the body system. If there is an abnormal growth and division of cells without any controlling limit, then it results in forming malignant tumor (excess tissue) in the prostate gland. Prostate cancer can spread to the other parts of the body like lungs, liver, heart and bones.

Causes of pancreatic cancer: There are no exact answers for this question. And more over this disease is not contagious to spread to others. Many of the researchers identified the risk factors for this disease.

Risk factors for Prostate cancer: Researchers identified some risk factors which increases the chance of occurrence of pancreatic cancer, they are:

Lung cancer is caused by uncontrolled rapid growth of cells in tissues. This type of cancer is most common and results in more than a million deaths  
everyear. This form of cancer is indicated by weight loss or coughing up blood or regularly going out of breath .

Lung cancer can be noticed on chest radiograph also called CT Scan. The treatment that one gets depends on the stage that one is in .Treatment of cancer  
include surgery ,chemotherapy and radiotherapy .

CLASSIFICATION

Lung cancers are classified after studying under them microscope .Classification is necessary as different type of cancer is treated differently.
Large portion of lung cancer are carcinomas – malignancies that grow from epithical cells .Lung-carcinomas are categorized into two types : non-small and  
small-cell lung carcinoma. Non-small cell lung carcinoma and small cell lung carcinoma account for 80.4% and 16.8% frequency of lung cancer, respectively .

NON-SMALL CELL LUNG CARCINOMA

The non-small cell lung carcinomas are grouped together as their prognosis and management are same upto  some extent .They are further classified into three  
types :  squamous cell lung carcinoma ,adenocarcinoma and large cell lung carcinoma .

Squamous cell lung cancer originates near a central bronchus .They account for 25% of lung cancers .

Adenocarcinoma starts in perpheral lung tissue . The cases of adenocarcinoma are a result of smoking .They accounts to 40% of non-small cell lung cancers.

SMALL CELL LUNG CARCINOMA

What is leukemia cancer: Leukemia is a termed as a serious cancer that occurs in the tissue that forms blood cells. Leukemia causes the bone marrow to produce abnormal white blood cells which are known as leukemia cells. These cells don’t die when they should and moreover causes damage to the normal cells by stopping their nature of work. Leukemia cells contain three main characteristics.Leukemia cancer also causes multiple myeloma cancer disease.

• Rapid growth without controlling limit.
• Mobility of these uncontrolled cells from original state to distant state.
• Destruction of adjacent body tissues by the spreading of uncontrolled cells through blood or lymph.

Leukemia cells damages white blood cells, red blood cells and platelets. They completely damage the stem cells from producing white blood cells, red blood cells and platelets.

Leukemia cancer is categorized in two four types they are: Leukemia is classified into chronic and acute by staging the advancement of the disease.

• Chronic lymphocytic leukemia: This disease grows slowly and affects the lymphoid cells. This type of disease can be found in only adults. More than 15000 cases of chronic lymphocytic leukemia are registered for every year.

• Chronic myeloid leukemia: This disease grows slowly and affects the myeloid cells. For every year, more than 5000 cases of chronic myeloid leukemia are registered. This type of disease can be found in only adults.

The Patient Protection and Affordable Care Act, otherwise known as the health reform bill will impact almost every American. One of the most important ways it will affect individual health insurance is that insurance companies will not be permitted to deny insurance to those with preexisting illnesses. Another important affect is that all Americans will be required to hold insurance. Insurance companies will be prohibited from placing annual and lifetime limits on coverage. Group health exchanges may also help to reduce the cost of insurance plans, giving individuals the buying power of large companies. You will be able to purchase insurance through a state exchange from 2014. The exchanges have yet to be formed, but the intended goal is to provide more affordable and subsidized individual plans. The Obama effects on individual health insurance addresses the biggest weaknesses in the individual health insurance market. Easy To Insure Me

As the reform bill was passed policy rates were climbing. A report revealed that members of the middle class were losing health insurance faster than any other income group. Those who missed the Government provided safety net because of their income were thrown on the mercies of the individual market. Here, insurers have been denied coverage based on preexisting conditions and are vulnerable to charges of high and ever increasing premiums.

Thyroid cancer: Thyroid cancer occurs in the thyroid gland. Thyroid gland is useful in producing two cells, follicular cells and C cells. Follicular cells produce thyroid hormone to control the effect of heart rate, energy levels and body temperature and C cells control the level of calcium in the body by producing calcitonin hormone. Thyroid cancer blocks the production of this hormone by producing cancer cells in the thyroid glands.
Thyroid cancer is defined as the disorder in the life cycle of thyroid gland cells. This occurs due to the unusual growth of the thyroid cells without controlling limit. These cancer cells move from original state to distant state and causes destruction to adjacent body tissues by the spreading of uncontrolled cells through blood or lymph.

Thyroid cancer is a combination of several cancers with different types of causes, symptoms and treatments. This cancer is of three types, in which abnormal growth of cells is common in all of them. The normal cells are the basic unit of life, they grow and divide into more cells when the body requires them. These cells forms the tissues and then organs, they are the building blocks of the body system. If there is an abnormal growth and division of cells without any controlling limit, then it results in forming tumor (excess tissue) in the body.

Tumors are of two types, they are as follows:

• Benign tumor
• Malignant tumor

What is Lung cancer: Cancer which is found in the lungs is termed as lung cancer. Lungs are the softy organs located in the chest on both either side of the heart. Lungs are the essential organs useful in supplying oxygen in the blood to various parts of the body. Lung cancer is referred as the malignant tumor because it spreads through out the body, lung cancer cells usually travels through blood vessels into tissues and lymph nodes. So, during surgery process the lymph nodes are also removed to check for the cancer cells.

Lung cancer can spread to bone, gynecologic sytem, gastrointestinal system, heart and other organs. This kind of spreading nature is defined as metastatic lung cancer.

Occurrence of Lung cancer:

Lung cancer is a combination of several diseases with different types of causes, symptoms and treatments. It is of many types, in which abnormal growth of cells is common in all of them. Generally normal cells plays major role in defining cancer. All the organs and tissues in the body are made up by tiny body cells. These cells have a constant process of dying and replacing new cells. This is the general process carried by them, if there is any malfunction in their life cycle then there is a chance for the occurrence of lung cancer. Tumor occurs due to the formation of excess cells in the body. There are two types of Tumors one is benign tumor and the other is malignant tumor .Benign tumor is not cancerous but can cause damage to the adjacent organs if it grows continuously at a single site. Malignant tumor is cancerous. It spreads through out the body and damages the entire body organs.

Asbestos cancer is caused by exposure to asbestos. Asbestos is a group of naturally occurring minerals that can be separated into thin threads. Asbestos fibers resist heat and fire and for this reason, have been used in many products that need to be resistant to heat and fire such as brake pads, gaskets and pumps. Unfortunately, however, asbestos-containing products can cause asbestos cancer.

Asbestos cancer: The types

There are different types of asbestos cancer. They include lung cancer and mesothelioma. There are two types of lung cancer:

Small cell lung cancer (SCLC) and

Non-small cell lung cancer (NSCLC)

Small cell lung cancer is the less common form of lung cancer and constitutes about 20% of lung cancer cases. Small cell lung cancer occurs almost exclusively in cigarette smokers. It is the more aggressive type of lung cancer and by the time it is diagnosed, it has usually spread to many areas of the body.

Non-small cell lung cancer is the most common type of lung cancer occurring in about 80% of lung cancer cases. Non-small cell lung cancer can have various causes including asbestos exposure.

Mesothelioma is also a form of asbestos cancer. It affects the mesothelium, which is the membrane that covers the body’s internal organs. The mesothelium produces a fluid to allow organs to glide against adjacent structures. The peritoneum is the mesothelium that covers organs within the abdominal cavity. The pleura is the mesothelium that covers the lungs and lines the wall of the chest cavity. The pericardium is the mesothelium that surrounds the heart.
