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.

      Well, dang Lisa, you hit the cancer jackpot! I also must add you really are a winner because these were both caught at early stages!!!! It is always difficult to say what is going to be happening as far as your treatment because it truly depends on your individual cancer cells. You have a lot of information right now but your oncologist will lay out your treatment plan and YOU WILL BE OK! It isn't a picnic but as someone said to me, "It's not your mother's chemotherapy." Meaning.... it has been made much more tolerable. We have all been there and know the path you are on right now. We are here to help you through this and are sorry you joined the club. This is the only club were we hate getting new members... sigh. Hang in there Lisa, please keep in touch with us. (That is an adorable pupper-doodle you have!!!) Take care, Sharon

      I have chemo every Friday and the third Friday I have Taxater, Herceptin and Charbo. The triple cocktail kicks my butt for a week. My Dr. Is giving me extra nausea and fluids to help me. So far it's working but fighting low energy.

      Sounds like dose dense, but not the type. Dose dense is supposed to be better. In that it hits the cancer harder, from what I've read.

      I found a very nice discussion on another website about this topic. Several women who had this diagnosis, were talking among themselves. They didn't make this sound earth-shattering. It seemed the women were under 40 and were node negative (no cancer found in lymph nodes) but there was cancer found in blood vessels to the nodes. Here is the link. I think you will find it very informative and not scary. Hang in there, gal!

      Yes!!! This is normal if you have fibrous tissue in your breasts. Most women under 45 experience this. Vitamin E 400iu can help with tenderness but you have to lay off the caffeine and chocolate...
