Stages of Cancer• Stage 0 - non-invasive; no evidence of cancer
cells• Stage I - started to invade the tissues in the
breast• Stage II - invasive breast cancer found in the
axillary (arm pit) lymph nodes• Stage III - inflammatory breast cancer• Stage IV – metastatic cancer; cancer cells that
have spread throughout the body organs
