Some of the known risk factors for breast cancer include:

Age: The risk of developing breast cancer increases as a person gets older, with most cases occurring in women over the age of 50.

Gender: Breast cancer is more common in women than in men.

Family History: Having a first-degree relative (mother, sister, or daughter) who has had breast cancer increases a person’s risk of developing the disease.

Personal history: A person who has had breast cancer in one breast is at increased risk of developing cancer in the other breast or a different part of the same breast.

Genetic Mutations: Inherited changes in certain genes, such as BRCA1 and BRCA2, can increase a person’s risk of developing breast cancer.

Reproductive History: Women who started menstruating at an early age or who have a late menopause are at increased risk. Women who have never been pregnant or who had their first child after age 30 are also at higher risk.

Hormone Therapy: Long-term use of hormone replacement therapy (HRT) or oral contraceptives may increase a person’s risk of developing breast cancer.

Lifestyle Factors: Poor diet, lack of physical activity, and alcohol consumption have also been linked to an increased risk of breast cancer.
