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.

      Don't freak out. It's probably a cyst.

      They found my suspicious lump on a mammo and then I was send for an ultrasound which I later found out pretty much confirmed that it was a malignancy - they can tell by shape and density, etc. That was followed up by a needle biopsy which confirmed that I did indeed have breast cancer. You will usually then have other tests like an MRI and a PetScan. Please let us know if you have any more questions.

      I had the same issue. Surgery on right side, port on left. About 6 months after my last chemo, my arm on left side started going numb. I talked to my oncologist and he thought it was maybe a small blood clot where the port goes into the vein. I got my port removed (I was done with it anyway)...

      I know a women who had cancer cone back to lung and liver met. She was estrogen positive - given arimidex and has no evidence of disease a year later. There are some good stabilizing treatments for many stage 4 cancers.... Can't totally get rid of it, but can live with decent quality of life.
