What are the stages of triple
negative breast cancer?

The stage of breast cancer is a way of describing how big the breast cancer is and which parts of the body are affected.1

The stage of the cancer helps you and your doctor:

  • Figure out the likely outcome of breast cancer treatment (your prognosis)
  • Decide on the best treatment options for you
  • Determine if certain clinical trials may be a good option for you

The number staging system divides breast cancers into 4 main stages, from 1 to 4. (There is also a stage 0, which refers to ‘pre-invasive’ breast cancer such as ductal carcinoma in situ or DCIS)

Stage 0 refers to ‘pre-invasive’ breast cancer such as ductal carcinoma in situ (DCIS) or lobular carcinoma in situ (LCIS)

Stage I, Stage IIA and Stage IIB (early) refer to early breast cancer

Stage IIB (advanced), Stage IIIA, Stage IIIB, Stage IIIC and Stage IV refer to advanced breast cancer (locally advanced breast cancer or metastatic breast cancer).

How quickly does triple-negative breast cancer progress?

Triple-negative breast cancer (TNBC) is considered an aggressive cancer because it grows quickly, is more likely to have spread at the time it’s found, and is more likely to come back after treatment than other types of breast cancer.2

Keep in mind that this information is based on previous outcomes of large numbers of people who had a specific cancer, but they can’t predict what will happen in any particular person’s case.

Information on TNBC can be confusing and may lead you to have more questions. Talk with your doctor using questions from our TNBC Patient Discussion Guide to become more familiar with your specific situation.

What does breast cancer grade mean?

The grade describes how cancer cells look under the microscope and whether they are similar or very different to normal cells.3

Low grade (grade 1)
The cells look similar to normal breast cells and are slow growing. These cancers tend to grow and spread slowly and have a good outlook (prognosis).

Intermediate grade (grade 2)
The cells look quite different to normal breast cells. This means the features and outlook (prognosis) are somewhere between well and poor.

High grade (grade 3)
The cells look very different to normal breast cells, are faster growing, and have abnormal features. They tend to grow and spread more quickly and have a worse outlook (prognosis).
