However, even with dense breasts, a screening mammogram is still the most effective method to detect breast cancer early for women over age 50. Dense breasts also tend to be more common in younger women or women with a lower body mass index. In addition, breast density tends to decrease as women become older.

Why do I have breast tissue in my armpit?

The takeaway

It's often caused by excess weight, but hormones and genetics may also play a role. In some instances, armpit fat may actually be a condition called axillary breast.
