Subchapter: 1 - What is Cancer?

What is Cancer?
Healthy cells are the basic building blocks of all tissue and organs in the body. But when cell DNA (the cell’s wiring) is damaged, mutated cells begin to rapidly reproduce without following the pre-wired plan.

Aggressive cell growth can form a tumor (or mass of tissue) that, like each individual cell, does not function as originally intended. These abnormal cells or groups of cells can progress into the disease known as cancer.

Cancer Origins
Breast cancer usually begins either where the milk is being produced, the lobules, or in the milk ducts.

Lobules
Lobular Carcinoma in Situ (LCIS) is a pre-cancerous condition that forms and is contained in the lobules. Invasive lobular carcinoma is a type of cancer that develops and breaks through the lobules, with the potential to spread to other areas of the body.

Milk Ducts
Ductal Carcinoma in Situ (DCIS) is a type of cancer that forms in the milk ducts and is considered non–invasive because it has not spread to any surrounding tissue. Once the cancer has spread beyond the milk ducts, it is known as ductal carcinoma.

Less frequently, breast cancer can originate in the stromal tissue– the fatty and fibrous connective tissue of the breast.

Prognosis
Treating breast cancer as soon as it’s discovered is very important. If left untreated, the cancer cells may invade healthy breast tissue or lymph nodes. Once in the lymph system, cancer can spread more easily to other parts of the body.

      I think you are going to have to try that again. Don't you just hate auto-spell-check?

      If you are asking about an aspiration type of biopsy, then NO it doesn't automatically mean you have cancer. You wait for the results come back from the lab. Many more women have biopsies that come back negative, rather than positive. You had the biopsy done because the other tests were inconclusive. A test of some of the suspicious cells are the only way to really diagnose whether it is cancer or not. Take care, Sharon

      It means pretty much just that. Usually cancers have blood flows because that is how they are nourished to grow. You NEED to contact your doctor for a definite meaning in your specific case. Take care, Sharon
