What are the risk factors for breast cancer?

Breast cancer risk factors include:

Age: As you become older, your chance of getting breast cancer rises. Women over 55 are most often diagnosed with invasive breast cancer.
Consuming alcohol: Your risk is increased by alcohol use disorder.
Dense breast tissue: Mammograms are challenging to interpret when breast tissue is dense. Your chance of developing breast cancer is also increased.
Gender: Compared to men, women are far more likely to acquire breast cancer.
Genes: Breast cancer is more likely to strike those who have the BRCA1 and BRCA2 gene mutations than those who do not. Other gene mutations may also impact your risk.
Early period: You have a higher chance of developing breast cancer if you start your periods before becoming 12 years old.
Having a baby at a later age: Breast cancer risk is higher in those with their first child after age 35.
Hormone therapy: Breast cancer risk increases in those who have taken or are now taking postmenopausal estrogen and progesterone drugs to cope with menopause symptoms.
Inherited risk: You have a higher chance of getting breast cancer if you have a close female relative who has. Your mother, grandmother, sister, or daughter are included in this. You may still get breast cancer even if your family has never had the disease. Most of those who contract it don't have a family history.
Menopause begins late: Breast cancer risk increases for those who enter menopause after age 55.
No pregnancies: The likelihood of developing breast cancer is higher in those who have never conceived or carried a pregnancy to term.
History of breast cancer: If you've had breast cancer in one breast, you're more likely to have it in the other breast and in a different part of the breast that was previously impacted.
