Mastectomy
                     Mastectomy
INTRODUCTION
• A mastectomy is surgery to remove all breast tissue 
from a breast as a way to treat or prevent breast 
cancer.

Why it's done?
• A mastectomy is used to remove all breast tissue if 
you have breast cancer or are at very high risk of 
developing it. You may have a mastectomy to 
remove one breast (unilateral mastectomy) or both 
breasts (bilateral mastectomy).

Mastectomy for breast cancer treatment
• Ductal carcinoma in situ (DCIS), or noninvasive breast 
cancer
• Stages I and II (early-stage) breast cancer
• Stage III (locally advanced) breast cancer — after 
chemotherapy

Mastectomy for breast cancer treatment 
cont.
• Inflammatory breast cancer — after chemotherapy
• Paget's disease of the breast
• Locally recurrent breast cancer
Source: www.mayoclinic.org
When this can be recommended?
• You have two or more tumors in separate areas of 
the breast.
• You have widespread or malignant-appearing calcium 
deposits (microcalcifications) throughout the breast 
that have been determined to be cancer after a 
breast biopsy.
• You've previously had radiation treatment to the 
breast region and the breast cancer has recurred in 
the breast.
Source: www.mayoclinic.org
When this can be recommended?
• You're pregnant and radiation creates an 
unacceptable risk to your unborn child.
• You've had a lumpectomy, but cancer is still present 
at the edges (margin) of the operated area and there 
is concern about cancer extending to elsewhere in 
the breast.
• You carry a gene mutation that gives you a high risk 
of developing a second cancer in your breast.

Mastectomy to prevent breast cancer
• You might also consider a mastectomy if you don't 
have breast cancer, but have a very high risk of 
developing the disease.

Preventive Measures
• A preventive (prophylactic) or risk-reducing 
mastectomy involves removing both of your breasts 
and significantly reduces your risk of developing 
breast cancer in the future.

Prophylactic mastectomy
• A prophylactic mastectomy is reserved for those with 
a very high risk of breast cancer, which is 
determined by a strong family history of breast 
cancer or the presence of certain genetic mutations 
that increase the risk of breast cancer.
