There are three main locations of the lymph nodes that drain into the breasts. The importance of the lymph nodes are to filter out toxic substances in the body. Cancerous cells start inside the tubes or ducts of the breasts or lobules but may gradually drain into the lymph nodes. The damage is done when the cancer cells lymphatic vessels that drain the breasts, enter the lymph nodes, settle and proliferate. When this occurs, the cancer is more difficult to treat although it is not always fatal.
Awareness is half the battle to prevention.
Breast cancer varies with every person and as I stated earlier, is due to many different risk factors. It is important to be educated about breast cancer because there are many different lumps that may or may not be cancerous or lead to cancer. Lumps that occur in the breast are common and may not be cancerous and should be checked to make certain. These lumps occur in women about one or two weeks before their period. Fibrocystic disease occurs with hormonal changes.
