Stage 1A means that the tumour is 2 centimetres cm or smaller and has not spread outside the breast. Stage 1B means that small areas of breast cancer cells are found in the lymph nodes close to the breast and that:. You might have just the cancerous area removed with a border of normal breast tissue.
Stage 3 cancer means the breast cancer has extended to beyond the immediate region of the tumor and may have invaded nearby lymph nodes and muscles, but has not spread to distant organs.

Stage 0 breast cancer,ductal carcinoma in situ DCIS is a non-invasive cancer where abnormal cells have been found in the lining of the breast milk duct.
Breast cancer is defined as Stage 1 when it's evident but confined solely to the area where abnormal cell division began—in other words, it's growing but hasn't spread.
