Cancer ,also called malignancy, is an abnormal growth of cells. It sounds scary, but when you look at the dictionary definition it doesn't seem as scary. Caner can be a scary thing and most people can get nervous when there is even a possibility of cancer. There are more than 100 types of cancer, including breast cancer, skin cancer, lung cancer, colon cancer, prostate cancer, and lymphoma, but the one that is being researched is breast cancer.
Breast cancer is an uncontrolled growth of breast cells. To better understand breast cancer, it helps to understand how any cancer can develop. Cancer occurs when there are mutations in the genes that are responsible for regulating the growth of cells and keep them healthy. In the normal body cells replace

Benign tumors are not cancerous, because their cells are close to normal in appearance, while growing slowly, and do not invade tissues or spread to other parts in the body. Malignant tumors are cancerous and if left unchecked can eventually spread beyond the original tumor to others parts in the body.
Breast cancer is always caused by a genetic mistake. Only 5-10% of cancer patients get cancer from genetics that are inherited from their mother or father. Then 85-90% of breast cancer patients are due to genetic abnormalities that happen as a result of the aging process and the “wear and tear” of life in

Stage IIA describes invasive breast cancer in which: no tumor can be found in the breast, but cancer (larger than 2 millimeters) is found in 1 to 3 axillary lymph nodes (the lymph nodes under the arm) or in the lymph nodes near the breastbone (found during a sentinel node biopsy), the tumor measures 2 centimeters or smaller and has spread to the axillary lymph nodes, or the tumor is larger than 2 centimeters but not larger than 5 centimeters and has not spread to the axillary lymph nodes. Stage IIB describes invasive breast cancer in which: the tumor is larger than 2 centimeters but no larger than 5 centimeters; small groups of breast cancer cells -- larger than 0.2 millimeter but not larger than 2 millimeters -- are found in the lymph nodes, the tumor is larger than 2 centimeters but no larger than 5 centimeters; cancer has spread to 1 to 3 axillary lymph nodes or to lymph nodes near the breastbone (found during a sentinel node biopsy) , or the tumor is larger than 5 centimeters but has not spread to the axillary lymph
