The risk factors for breast cancer can be divided into those that cannot be changed and those that can be modified. Some of the risk factors that cannot be changed include:
- Getting older: The risk for breast cancer increases with age, and most breast cancers are diagnosed after the age of 50.
- Genetic mutations: Women who have inherited changes to certain genes, such as BRCA1 and BRCA2, are at a higher risk of breast cancer.
- Reproductive history: Factors such as starting menstrual periods before age 12, starting menopause after age 55, having the first pregnancy after age 30, not breastfeeding, and never having a full-term pregnancy can raise breast cancer risk.
On the other hand, some risk factors that can be changed include:
- Lack of physical activity: A sedentary lifestyle with little physical activity can increase the risk for breast cancer.
- Poor diet: A diet high in saturated fat and lacking fruits and vegetables can increase the risk for breast cancer.
- Being overweight or obese: Being overweight or obese, especially after menopause, can increase the risk for breast cancer.
- Drinking alcohol: Frequent consumption of alcohol can increase the risk for breast cancer.
Its important to note that having a risk factor does not mean someone will definitely get breast cancer, and not all risk factors have the same effect. Most women have some risk factors, but most women do not get breast cancer. Its advisable to talk with a doctor about ways to lower the risk and about screening for breast cancer.
