Mastectomy (cont.)

Results

  • If breast cancer is detected in its earliest stage, treatment results in a 10-year survival rate (that is, percent of women still living) of more than 90%. Long-term survival is similar whether the woman chooses lumpectomy or mastectomy. The difference between the treatments is the risk of recurrence locally (in the breast or on the chest wall). The 20-year risk of local recurrence after mastectomy is 3%-5% compared to 15%-20% after lumpectomy and radiation.
    • Self-examination of the breast and an annual mammography help in the early detection of breast cancer.
    • In the United States, yearly mammography screening is recommended for women older than 40 years.
  • In addition to mastectomy, treatments such as hormonal therapy, radiation therapy, and chemotherapy (if required) improve the chances of recurrence-free, long-term survival.
