Only 5-10% of diagnosed breast cancers are believed to be inherited, while there are important lifestyle-related factors that have been implicated in increasing the chances of developing the disease. To minimise these changes, we need to recognise the above harmful factors and avoid them:
- Over-consumption of calories, so that weight exceeds normal levels (BMI> 25)
- Limited consumption of healthy foods (fruits, vegetables, whole grains)
- Lack of exercise, since moderate to intense exercise for 4-7 hours a week, seems to reduce the risk of breast cancer.
- Consuming more than three portions of alcohol a week, compared to zero consumption, leads to a 15% increase in the chance of developing breast cancer.
- Smoking among the many diseases with which it has been associated appears to increase the likelihood of developing breast cancer in young, pre-menopausal patients.
- Menopause hormone replacement therapy for over 5-10 years and long-term use of contraceptives.
