✅ Lifestyle Matters: Healthy habits may reduce risk by 30-40%.
8 Proven Ways to Lower Breast Cancer Risk
1. Stay Physically Active
- Why? Exercise lowers estrogen levels & reduces inflammation.
- Goal: 150 mins/week of moderate activity (brisk walking, cycling).
- Bonus: Helps maintain a healthy weight.
2. Maintain a Healthy Weight
- Postmenopausal women with obesity have 20-40% higher risk.
- Tip: Aim for a BMI between 18.5–24.9.
3. Eat a Cancer-Protective Diet
| Eat More | Eat Less |
|---|---|
| Leafy greens, berries, cruciferous veggies | Processed meats (bacon, sausages) |
| Whole grains, legumes | Ultra-processed snacks (chips, sweets) |
| Healthy fats (olive oil, nuts, fatty fish) | Sugary drinks & refined carbs |
4. Limit Alcohol
- 1 drink/day increases risk by 7-10%.
- Best choice: Avoid or limit to <3 drinks/week.
5. Avoid Smoking
- Smokers have a 10-30% higher risk.
- Quitting helps—risk decreases over time.
6. Breastfeed If Possible
- Breastfeeding for 12+ months lowers risk by 4.3% per year.
7. Be Cautious with Hormone Therapy
- Long-term estrogen-progestin therapy increases risk.
- Discuss alternatives with your doctor.
8. Get Regular Screenings
- Mammograms start at age 40-50 (based on risk).
- Self-exams help detect changes early.
Breast Cancer Screening Guidelines
| Age Group | Recommendation |
|---|---|
| 40-49 | Discuss with doctor (earlier if high risk). |
| 50-74 | Mammogram every 1-2 years. |
| 75+ | Individualized based on health. |
| High Risk (BRCA+) | MRI + mammogram yearly from age 30. |
🔹 Women with dense breasts may need ultrasound or MRI for better detection.
