Breast lumps happen for many reasons. Lumps can be hard, smooth, soft or round. Most of the time, a breast lump doesn’t mean you have breast cancer. Many other conditions can cause breast lumps. Treatment for a breast lump depends on the cause. Some lumps don’t require any treatment.
A breast lump is a mass or growth that develops in your breast. While a breast lump can be a sign of breast cancer, it’s usually benign (not cancerous). In fact, 8 out of 10 breast lumps are noncancerous. If you feel a lump in your breast or under your arm, try not to panic. A healthcare provider can figure out the cause of the breast lump and determine if you need tests or treatment.
It’s a good idea to familiarize yourself with how your breasts normally look and feel so you’re able to notice any changes.

This condition can be related to a hormonal imbalance or a side effect of medication, although most cases are “idiopathic,” meaning that providers don’t know what causes it.
