About Breast Cancer
Based on National Cancer Registry Programme (ICMR), report of (2001-03), about 25% of the total Breast Cancer Cases among Indian women constitutes of Breast Cancer Treatment in India. Breast Cancer usually starts off in the inner lining of milk ducts or the lobules that supply them with milk. A malignant tumor can spread to other parts of the body. A Breast Cancer that started off in the lobules is known as lobular carcinoma, while one that developed from the ducts is called ductal carcinoma.
Breast cancer starts in the cells of the breast. A cancerous (malignant) tumour is a group of cancer cells that can grow into and destroy nearby tissue. It can also spread (metastasize) to other parts of the body. Cells in the breast sometimes change and no longer grow or behave normally. These changes may lead to non-cancerous (benign) breast conditions such as atypical hyperplasia and cysts. They can also lead to non-cancerous tumours such as intra-ductal papillomas. But in some cases, changes to breast cells can cause breast cancer. Most often, breast cancer starts in cells that line the ducts, which are the tubes that carry milk from the glands to the nipple. This type of breast cancer is called ductal carcinoma. Cancer can also start in the cells of the lobules, which are the groups of glands that make milk. This type of cancer is called lobular carcinoma. Both ductal carcinoma and lobular carcinoma can be in situ, which means that the cancer is still where it started and has not grown into surrounding tissues. They can also be invasive, which means they have grown into surrounding tissues.
