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.

      This depends on whether your laboratory is reporting using the English/Australian system often called the Nottingham Index or Bloom and Richardson VERSUS the American system.

      You did not say which country you were posting from.

      The answer above is correct for US and US based tumour rating...

      The answer above is correct for US and US based tumour rating systems BUT in the Nottingham Index used in UK, Australia etc a Grade 3 means three individual scores of 1 [lowest risk] added together equals 3. Which under that system is the LOWEST score or the least aggressive form of cancer, not the more aggressive.

      I believe the grade is for agressiveness. 1. is mild, 2. moderate and 3. very agressive.

    I'm getting blisters on my feet right where I have thick callouses. Doc says to use Epsom salts and rest. Anyone else had this?

      It's a common side effect of chemo. I finished almost 7 months ago and the sides of my feet near the soles are still calloused! I had some thick skin, heavy peeling, etc. and while it's better, it's still an issue. I honestly don't know what causes it but I know it's not uncommon.

      I have had blisters and peeling feet since chemo 4 of 6. One heel completely peeled off first level of skin. I finished chemo 6 three weeks ago and feet are still peeling. I don't do anything special to treat them but I did get a pedicure today and I feel better. Good luck and hang in there.

      Finding 2 lumps is scary. 80% of lumps are not cancer, but please go to the doctor soon, for peace of mind and to determine what they are. Early detection saves lives. Keep us posted on the results.

      Atypia or atypical ductal hyperplasia (ADH) is a condition putting you at increased risk for breast cancer. If this is discovered at breast biopsy, this is removed surgically because it can be upgraded to breast cancer when it is resected.
