Most breast lumps are noncancerous, which means they are benign. You might be surprised to find a breast lump, but itâ€™s important to remember that it may not affect your long-term health.
However, a breast lump can be a sign of cancer. Itâ€™s wise to always seek a medical evaluation of any lumps or swelling you discover on your breasts.
Although breasts are commonly associated with women, breast tissue is present in both men and women. Your hormones affect this tissue. Hormonal changes can cause lumps to form and, in some cases, to naturally disappear. You can develop breast lumps at any age.
Some babies develop breast lumps due to the estrogen they get from their mothers during birth. These generally clear up as the estrogen leaves their bodies.
Pre-pubescent girls sometimes get breast lumps that feel tender. These usually go away naturally during puberty. Adolescent boys can also get breast lumps during puberty. These are temporary and usually disappear in a few months as well.
