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.

      Robert,

      My brother-in-law was diagnosed with breast cancer last year. He was having some pain in his breast, felt the area and found a lump. He tried to look at it in the mirror, rubbed the lump and had some discharge from his nipple. He was being seen by his doctor for something else the next week and mentioned it to his doctor. Doctor referred him for a mammogram, which confirmed a couple of suspicious lumps. He had an ultrasound, a biopsy which diagnosed infiltrating ductal carcinoma.... (JUST like mine!!!) He had a mastectomy, and a oncoDX test was made of the tissue. An oncoDX test is a predictor is the cancer was the type that would likely reoccur, thus recommending treatment with chemotherapy. The scale is from 0 to 100. 0 = no reoccurrence 100= will reoccur. His score was -0- so he was done with his treatment!!! Anyway.... even though breast cancer is relatively rare in men, it can still happen. The symptoms are the same. If you have a lump in your breast..... man-up and have it checked!!! This site or breastcancer.org. will have symptoms of breast cancer. Early detection is the key to getting rid of this sneaky disease. Hang in there... Take care, Sharon

      You should consider genetic counselling to get an accurate assessment of your risks of developing breast cancer especially if your family members were diagnosed with breast cancer at younger ages (less than 50 years).

      Yeah but nowdays, if you diagnose soon enough, and have the correct treatment, is much more likely to have it cured. My mom had it and treated for almost 2 years, but now she's ok!

      This is an unusually wonderful site and it just feels like a wonderful group of supportive pals. As for ovarian cancer.... you might Google Ovarian Support Group and try out to see if they make you feel. I hope you can find a site like this one. I can't thank the organizers enough for setting it up. It is a Godsend to many. I can tell you a site NOT to join for any healthrelated questions. Hang in there Patsy and take care, Sharon
