Having a breast cancer family history risk is an important factor in assessing a woman’s chances of developing the disease. If a close relative has been diagnosed with breast cancer, your own risk may be higher than average.
Recognising this connection can help with early detection and proactive steps toward prevention. Understand your genetic predisposition and seek the right screenings with the guide of our breast specialist, Dr Andrew Lee.
How Family History Increases Risk
Having a family history of breast cancer can double your risk, especially if a first-degree relative—such as a mother, sister or daughter—has been diagnosed. The risk increases further if multiple relatives on the same side of the family have had breast cancer. However, even distant relatives with a history of breast cancer can contribute to an elevated risk.
While family history plays a role, not all breast cancers are inherited. Many cases occur without a genetic link, but those with multiple affected family members should consider discussing their risk factors with our specialist.
Inherited Genetic Mutations
Some cases of breast cancer are linked to inherited genetic mutations, most commonly BRCA gene mutation in BRCA1 and BRCA2. These mutations significantly raise the risk of both breast and ovarian cancers.
In addition to BRCA1 and BRCA2, other genetic mutations, such as PALB2 and TP53, can also contribute to hereditary breast cancer. If you have a strong family history of breast cancer, genetic testing may provide valuable insights into your level of risk.
Should You Consider Genetic Testing
Genetic testing can help identify whether you carry a BRCA gene mutation or other high-risk mutations. It is recommended for individuals with:
A first-degree relative diagnosed with breast cancer at a young age
Multiple family members affected by breast or ovarian cancer
A known family history of BRCA mutations
Understanding your genetic test results allows you to take preventive measures, such as increased screening, lifestyle changes or discussing risk-reducing strategies with our breast surgeon.
Breast Cancer Screening for High-Risk Individuals
For those with breast cancer family history risk, early and frequent screening is essential.
High-risk individuals should follow specific screening strategies, including:
- Annual mammograms starting earlier than the general population
- Breast MRI for enhanced detection, particularly in dense breast tissue
- Clinical breast exams conducted regularly by our breast specialist
Early detection improves treatment outcomes, making these screenings a critical component of breast cancer prevention.
Personalised Breast Cancer Risk Assessment with Dr Andrew Lee
Dr Andrew Lee offers comprehensive risk assessments and personalised care for women with a family history of breast cancer. With expertise in imaging techniques and tailored screening schedules, Dr Lee ensures patients receive the optimal preventive measures and treatment options.
Steps in risk assessment may include:
- Reviewing your personal and family medical history
- Identifying potential genetic risks
- Recommending breast cancer genetic testing if necessary
- Developing a customised screening and prevention plan
- Providing guidance on lifestyle changes to lower risk
- Maintain a Healthy Weight – Excess body fat, particularly after menopause, increases estrogen levels, which can fuel hormone-sensitive breast cancers.
- Stay Physically Active – Regular physical activity helps regulate hormones, improve immune function and support healthy weight management. Aim for at least 150 minutes of moderate-intensity exercise per week, such as walking, swimming or cycling. Strength training also helps maintain muscle mass and overall metabolic health.
- Limit Alcohol Consumption – Even small amounts of alcohol can raise estrogen levels and damage DNA, increasing breast cancer risk. If you choose to drink, limit alcohol intake to one drink per day or less, or consider cutting it out altogether.
- Avoid Smoking – Smoking is linked to many cancers, including breast cancer, due to the harmful chemicals that can damage DNA and cause chronic inflammation. Quitting smoking not only reduces cancer risk but also improves overall health and lung function.
- Eat a Nutrient-Rich Diet – A diet rich in fruits, vegetables, whole grains and healthy fats can help protect against cancer. Foods like berries, leafy greens, nuts and fatty fish contain antioxidants and anti-inflammatory compounds that support cellular health. Reducing processed foods, sugar and red meat can also benefit breast health.
- Manage Stress Levels – Chronic stress can impact hormone levels and weaken the immune system, potentially contributing to cancer risk. Practising stress management techniques such as meditation, yoga deep breathing or engaging in hobbies can support emotional and physical well-being.
- Prioritise Sleep and Rest – Poor sleep and irregular sleep patterns can disrupt hormone balance, particularly melatonin, which plays a role in regulating estrogen. Aim for 7-9 hours of quality sleep each night and maintain a consistent sleep schedule to support your body’s natural rhythms.
7 Lifestyle Choices to Lower Your Risk
Although genetic factors contribute to breast cancer family history risk, lifestyle choices can play a significant role in reducing your overall risk. While you cannot change inherited factors, adopting healthier habits can help protect your breast health.
