Risk Reduction clinics

1. Risk Assessment:

Clinics perform a comprehensive assessment of a patient’s risk for breast cancer. This typically includes:

• Personal and Family History: Gathering information about any previous cancers and family history of breast, ovarian, or other cancers.
• Genetic Testing: If deemed appropriate, patients may be offered genetic testing to check for mutations in genes associated with an increased risk of breast cancer, such as BRCA1, BRCA2, and others (TP53, PALB2, etc.).
• Risk Models: Various models, such as the Gail Model, Tyrer-Cuzick model, or BOADICEA may be used to estimate a woman’s individual risk of developing breast cancer.

2. Genetic Counseling:

• Genetic counselors are a crucial part of risk reduction clinics. They help patients understand the implications of genetic testing results and guide them in making informed decisions about their options.
• Women who test positive for gene mutations such as BRCA1/BRCA2 are at a significantly increased risk of breast and ovarian cancers, and genetic counselors help in discussing preventive measures.

3. Enhanced Screening Protocols:

For women at high risk, clinics often recommend more frequent or earlier screening than is standard for the general population. Enhanced screening may include:

• Annual mammograms starting earlier (sometimes as early as age 25-30).
• Breast MRI: This is often recommended in addition to mammography for high-risk women, as it is more sensitive in detecting early breast cancers, particularly in dense breast tissue.
• Clinical breast exams: Regular physical exams by healthcare providers may be conducted more frequently.

4. Lifestyle Interventions:

Many risk reduction clinics provide guidance on lifestyle changes that can help lower breast cancer risk. This might include:

• Diet and exercise counseling: Promoting a healthy lifestyle through a balanced diet, regular physical activity, and maintaining a healthy weight, all of which have been shown to possibly reduce the risk of breast cancer.
• Alcohol and smoking cessation: Reducing alcohol intake and quitting smoking are important recommendations, as both are associated with an increased risk of breast cancer.

5. Chemoprevention:

Some women at high risk may be candidates for chemoprevention, which involves the use of medications to lower breast cancer risk. Two commonly used drugs include:

• Tamoxifen: Often used for premenopausal women at high risk.
• Raloxifene: Typically used for postmenopausal women at high risk.

These drugs have been shown to reduce the risk of estrogen receptor-positive (ER-positive) breast cancers but are associated with side effects, so careful assessment is necessary.

6. Surgical Risk-Reduction Options:

For women at very high risk, such as those with BRCA1 or BRCA2 mutations, surgical options to reduce risk are often considered:

• Prophylactic Mastectomy: Removing one or both breasts to significantly reduce the risk of breast cancer by up to 90%. This option is often considered by women with a strong family history or genetic predisposition.
• Prophylactic Salpingo-Oophorectomy: Removal of the ovaries and fallopian tubes to reduce the risk of ovarian cancer and, to a lesser extent, breast cancer in women with BRCA mutations.
• These decisions are typically made after extensive consultation with surgeons, genetic counselors, and oncologists to assess the risks, benefits, and timing of such procedures.

7. Psychological Support:

• Risk reduction clinics provide access to counselling and psychological support to help women cope with the emotional and psychological impact of living with a high risk of breast cancer or making difficult decisions about preventive surgery or chemoprevention.
• Support groups and therapy can also be offered to provide emotional support, especially for women considering prophylactic surgery.

8. Monitoring and Follow-Up:

• Women at risk are closely monitored with regular follow-up appointments to track any changes in their health, discuss updated risk assessments, and adjust preventive strategies as needed.
