Risk Reducing Mastectomy
Risk Reducing Mastectomy is a surgical procedure designed to significantly lower the risk of developing breast cancer in individuals identified as having a high genetic or familial predisposition to the disease. This proactive measure involves the removal of healthy breast tissue before cancer has a chance to develop.

Key Takeaways
- Risk Reducing Mastectomy is a surgical option for individuals at high risk of breast cancer.
- It involves removing healthy breast tissue to drastically lower future cancer risk.
- Candidates typically have strong family histories or genetic mutations like BRCA1/2.
- Benefits include substantial risk reduction and psychological relief, but potential risks and body image changes exist.
- The decision for this procedure is highly personal and requires thorough consultation with healthcare professionals.
What is Risk Reducing Mastectomy?
Risk Reducing Mastectomy, also known as a preventive mastectomy procedure, is a surgical intervention performed to reduce the likelihood of developing breast cancer. This procedure involves the removal of one or both healthy breasts in individuals who are at a significantly elevated risk of the disease. The goal is to remove the majority of the breast tissue where cancer could potentially form, thereby dramatically lowering the risk.
This procedure is distinct from a mastectomy performed to treat existing breast cancer. Instead, it is a prophylactic measure, meaning it is undertaken to prevent a disease from occurring. While it cannot eliminate the risk entirely, as some breast tissue may remain, it can reduce it by a substantial margin, often by 90% or more for high-risk individuals. The decision to undergo this surgery is a deeply personal one, made after careful consideration of individual risk factors, psychological impact, and potential outcomes.
Who Should Consider Risk Reduction Mastectomy?
Individuals who should consider a Risk Reduction Mastectomy are typically those with a significantly elevated lifetime risk of developing breast cancer, far exceeding that of the general population. This elevated risk is often determined by a combination of genetic factors, family history, and personal medical history. Healthcare providers assess these factors to identify suitable candidates for this proactive surgery.
Key indicators for considering a risk reduction surgery breast cancer include:
- Genetic Mutations: Carrying specific genetic mutations, such as BRCA1 or BRCA2, which are strongly linked to an increased risk of breast and ovarian cancers. Other less common mutations like PALB2, CHEK2, and ATM also increase risk.
- Strong Family History: A significant family history of breast cancer, particularly in first-degree relatives (mother, sister, daughter) diagnosed at a young age, or multiple family members affected by breast or ovarian cancer.
- Previous Radiation Therapy: A history of radiation therapy to the chest area at a young age, which can increase the risk of developing breast cancer later in life.
- Prior Breast Biopsies: A personal history of certain high-risk benign breast conditions, such as atypical ductal hyperplasia (ADH), atypical lobular hyperplasia (ALH), or lobular carcinoma in situ (LCIS), which indicate an increased risk for future cancer development.
A comprehensive genetic counseling and risk assessment process with a specialized medical team is crucial to determine if this procedure is the right choice for an individual.
Benefits and Potential Risks of Prophylactic Mastectomy
The decision to undergo a prophylactic mastectomy benefits from careful consideration of both its significant advantages and potential drawbacks. The primary benefit is a drastic reduction in the lifetime risk of developing breast cancer. For individuals with BRCA1 or BRCA2 mutations, studies indicate that a bilateral prophylactic mastectomy can reduce the risk of breast cancer by up to 90-95%, according to organizations like the National Cancer Institute (NCI). This significant reduction can offer profound psychological relief and peace of mind for those living with high-risk factors.
However, like any major surgical procedure, a prophylactic mastectomy carries potential risks and considerations. These include:
- Surgical Complications: Standard surgical risks such as infection, bleeding, pain, swelling, and adverse reactions to anesthesia.
- Aesthetic Changes and Body Image: The removal of breast tissue permanently alters the appearance of the chest. While breast reconstruction is often an option, it may not perfectly replicate the natural breast, and some individuals may experience dissatisfaction with their body image or loss of sensation.
- Psychological Impact: Despite the reduction in cancer anxiety, some individuals may experience feelings of loss, grief, or changes in self-esteem and sexuality.
- Reconstruction Complications: If reconstruction is performed, potential complications include implant rupture, capsular contracture, or issues with flap surgery.
- Not 100% Risk Elimination: While highly effective, a small amount of breast tissue may remain, meaning the risk of developing breast cancer is significantly reduced but not entirely eliminated.
It is essential for individuals considering this surgery to have open and honest discussions with their healthcare team, including surgeons, oncologists, genetic counselors, and mental health professionals, to weigh these factors against their personal risk profile and quality of life considerations.
