Chapter: 5 - Types & Stages

Subchapter: 2 - Stage 0 & 1

Stage 0
Stage 0, DCIS (Ductal Carcinoma in Situ) is a noninvasive cancer where abnormal cells have been found in the lining of the breast milk duct.

Even though Stage 0 cancer is still noninvasive, it does require immediate treatment and is typically treated with surgery or radiation, or a combination of the two. Chemotherapy is not part of the treatment regimen for earlier stages of cancer.

Stage 1
In Stage 1 invasive breast cancer, the tumor has not exceeded 2cm (0.8in). Although it’s considered to be invasive, it has not yet spread to any surrounding lymph nodes or outside the breast tissue.

      I have stage 3C as well. Yes, it is extremely important that you get treated! Stage 3C has extensive lymph node involvement. Our stage is one step from stage 4 and could easily turn into 4 if left untreated. Stage four is when breast cancer metastasizes (spreads) to other organs, such as bones,...

      I have stage 3C as well. Yes, it is extremely important that you get treated! Stage 3C has extensive lymph node involvement. Our stage is one step from stage 4 and could easily turn into 4 if left untreated. Stage four is when breast cancer metastasizes (spreads) to other organs, such as bones, liver, brain, lungs, etc. I'm not trying to scare you but I want you to be one of the survivors! Please get treated. Some people say the treatments are worse than the disease. Not true in my opinion. Sure, the treatments don't make you feel good....BUT it doable! And you want to live!

      Yes it is very serious. I am a stage 3 also. Without treatment, the cancer will spread to other organs

    I am undecided about getting radiation for DCIS. Surgery turned up nothing - biopsy got it all. I'm thinking risk is low...

      I had dcis. Biopsy got everything also. The radiation decreases the risk of it recurring. Good luck with your decision.

      I was diagnosed with DCIS in Sept. My oncologist did not recommend radiation due to the (small) size of the area & wide (clear) margins. She told me to get a second opinion if I wasn't comfortable with that. Some oncologists believe that radiation should be given for all cases of DCIS. I...

      I was diagnosed with DCIS in Sept. My oncologist did not recommend radiation due to the (small) size of the area & wide (clear) margins. She told me to get a second opinion if I wasn't comfortable with that. Some oncologists believe that radiation should be given for all cases of DCIS. I decided to hold off on radiation & take aromatase inhibitors for 5 years (my feeling is that if I develop invasive CA later on, I want to have the option of radiation at that time.) Also, 2/3 of DCIS do not become invasive, so I'm concerned about over treatment. It's confusing, so do your homework, ask for advice, but know in the end, it's your decision.

    What is the significance of isolated tumor cells in a single lymph node? (a small five cell cluster of about 1mm)

      Although the amount of cells seems small, the significance lies in the fact that the cancer moved into the lymph nodes. Chemotherapy will insure that any cell that got free will be killed and your chance of recurrence will be reduced.

      I suggest speaking to your surgeon and to an oncologist, perhaps even requesting the Oncotype Dx testing of the cells.

      I suggest speaking to your surgeon and to an oncologist, perhaps even requesting the Oncotype Dx testing of the cells. I was faced with a similar situation - two microscopic cancer cells in my nodes - and after a great many sleepless nights, chose to follow my surgeon's advice. He said the cells were too small to test further and chemo would only increase my survival chances by approx. 2%, so I chose no chemo. After 4 years of Arimidex, I'm still going strong. Your situation may be different, certainly, so the advice of your doctors is critical. Ask lots of questions. Best of luck to you.

      It is unusual to get three opinions that do not agree. Did the second and third opinions completely rule out DCIS? I would want to be clear on that issue. Did they say why no tamoxifin? Unless you have a family history of bc, it would be usual to be closely followed. I'm sorry you are going...

I'm sorry you are going through this confusion about your diagnosis, but I would want to confident , and would get another opinion if I was not.
