This type of prevention involves the complete removal of both breasts and all breast tissue. By having this operation individuals are able to completely eliminate the risk of having breast cancer. In most cases this procedure is only done on women who have many members of their family (mothers, grandmothers, aunts) that have been diagnosed or died from breast cancer. In such instances there is usually a genetic reason why members of the same family have acquired breast cancer or other types of cancer. It is actually a genetic defect in which the proto-oncogene mutates and becomes an oncogene. Basically the job of the proto-oncogene is to create the code for the protein that controls cell division. When the proto-oncogene is defective the protein can not be produced properly. Without the proper production of the protein cancers are more likely to develop.
The survival rates for cancer depend upon what type of cancer...
Lung, Ovarian and Cervical cancers tend to have lower survival rates because by the time symptoms appear, the cancer is in a later stage. Other cancers that are caught in early stages such as stage one or stage two are usually treatable and the prognosis for survival can be rather good.
As it pertains to treatment there are several options that patients have including chemotherapy, radiation, changes in diet and more experimental treatments. The type of treatment the patient receives depends upon the type of cancer and the stage of the cancer. Some people do not receive any treatment at all for slow growing cancers; their doctors just monitor the growth of the cancer.

Cancer Under normal circumstances, cells deemed to be normal multiply when the human body needs them. When they are no longer needed, these cells die. However, for an individual with cancer, the growth as well as division of cells tends to be rather abnormal. The death of cancerous cells also differs from that of normal body cells. In this text, I concern myself with cancer. In so doing, I highlight the
Cancer Care KNOWING MORE ABOUT CANCER Approach to the Care of Cancer The integrative approach to cancer treatment is the most widely used by cancer patients today as it is the most comprehensive (Nelson, 2011). It is the method used by integrative oncology, which combines complementary therapeutic approaches and conventional therapies. As a combination, the integrated approach covers natural and botanical products, nutrition, acupuncture, traditional Chinese medicine and mind-body therapies. It fits together
Cancer The medical name for cancer is malignant neoplasm. There are approximately forty different types of cancers, including a few varieties of leukemia and lymphoma.

In fact, according to statistics gathered by leading clinics in the U.S.A., cancer is the second
Cancer Drugs For the past several decades, the news about cancer in the United States has been increasingly positive and that trend has continued unabated over the past decade. According to the National Cancer Institute at the National Institutes of Health, the overall incidence rate for men has declined by an average of 0.6% every year between 2004 and 2008, while for women, the incidence rate has dropped 0.5% per
Prostate Cancer in America Prostrate Cancer Prostate cancer is the cancer of the prostate glands. Prostate gland is a small walnut sized organ and an important part of a man's reproductive system. It is one of the most common forms of cancer in men aged above 75 years. The incidence of prostate cancer in men younger than the age of 40 is very rare. High risk population for the prostate cancer include
Coping With Cancer According to the American Cancer Society, cancer is the second leading cause of death in the United States. Half of all men and one-third of all women in the U.S. will develop cancer during their lifetimes. Today, millions of people are living with cancer or have had cancer. The numbers are dismal; according to most statistical data American's possess almost a fifty percent chance of developing cancer. With
