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.

      Mel,
      I would be very watchful of this condition. If it does not get better, go back to your doctor and request a biopsy of that area. I wouldn't wait any longer than a couple of weeks. It is probably nothing but so be on the very safe side, be extra cautious. There is a very, very, rare...

      Mel,
      I would be very watchful of this condition. If it does not get better, go back to your doctor and request a biopsy of that area. I wouldn't wait any longer than a couple of weeks. It is probably nothing but so be on the very safe side, be extra cautious. There is a very, very, rare aggressive BC (inflammatory breast cancer) that can start out this way. Take care, Sharon

      You should make an appointment and have your doctor check it as any changes to one's body need to be checked out.

      I have had breast cancer 4 times, all low stage and once spread to the lymph nodes. I had negative margins after each surgery. This 4th time, I'm taking chemo to hopefully knock this thing out for good. I think it probably has more to do if it spread to other areas and what stage it is. I have heard of women who live with breast cancer for a long time as a managed disease.

      Unfortunately, I don't think there's dedication at all on finding a cure for cancer in general. There is researches on new treatments, new medications, less invasive procedures. But meanwhile the pharmaceutical industry makes millions with diseases, nobody will give up the profits for the cure....

      Unfortunately, I don't think there's dedication at all on finding a cure for cancer in general. There is researches on new treatments, new medications, less invasive procedures. But meanwhile the pharmaceutical industry makes millions with diseases, nobody will give up the profits for the cure. When you know that 1 (one) session of chemotherapy runs around $30,000/$40,000, you understand what I mean!
