Risk Factors for Triple-Negative Breast Cancer
Both men and women may get triple-negative breast cancer. The condition is very rare in men and mostly occurs in women under 40 years old. Certain risk factors for this form of breast cancer may include:
– Genetics: A mutated BRCA gene may increase the risk of triple-negative breast cancer. It is estimated that around 70 percent of reported cases had this mutation. Studies have suggested that those with the BRCA1 mutation tend to be at a higher risk than those with the BRCA2 mutation. The exact cause is still not fully clear.
– Obesity: This is a major risk factor for all types of breast cancer.
– Premenopause: Triple-negative breast cancer is more common in those people who have not gone through menopause.
– Ancestry: The condition tends to affect Hispanic and African American women more than other ethnic groups. [4]
