Stage 3 invasive breast cancer includes various types of cancer. It is primarily based on the location and number of lymph nodes to which the cancer has spread, but it can also depend on the size of the tumor and if the chest wall or skin have been affected.

Stage 3A

Stage 3A is when the tumor is less than 2cm (0.8in) and the cancer has spread to connecting axillary (underarm) lymph nodes or lymph nodes near the breastbone. Stage 3A can also mean that the tumor is larger than 5cm (2in) and the cancer has spread to axillary lymph nodes that may be connected or lymph nodes near the breastbone.

Stage 3B

At Stage 3B the tumor can be any size and the cancer has either spread to the chest wall and/or the skin of the breast or to connecting axillary (underarm) lymph nodes or lymph nodes near the breastbone.

Stage 3C

In Stage 3C the tumor may be any size and is affecting the chest wall and/or skin of the breast. It has also spread to the lymph nodes near the collarbone.

Stage 3C breast cancer is divided into two types: operable and inoperable. Operable Stage 3C means that cancer has spread to ten or more axillary lymph nodes or that it has been found in lymph nodes below the collarbone. Cancer is considered inoperable Stage 3C when it has spread to lymph nodes above the collarbone.
