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
Treatments
Surgery:
Lumpectomy (tomy = “to cut”)
Mastectomy
Axillary lymph node dissection
Chemotherapy
Radiation therapy
Lifespan (Prognosis)

patients will survive.
• Stage 0 = 99
• Stage 1 = 92
• Stage 2 = 65
• Stage 3 = 44
• Stage 4 = 14
