A breast lump is a swelling, protuberance, or lump in the breast.
Normal breast tissue is present in both males and females of all ages. This tissue responds to hormonal changes and, therefore, certain lumps can come and go.
Breast lumps may appear at all ages:
Infants may have breast lumps related to estrogen from the mother. The lump generally goes away on its own as the estrogen clears from the baby's body. It can happen to boys and girls.
Young girls often develop "breast buds" that appear just before the beginning of puberty. These bumps may be tender. They are common around age 9, but may happen as early as age 6.
Teenage boys may develop breast enlargement and lumps because of hormonal changes in mid-puberty. Although this may distress the teen, the lumps or enlargement generally go away on their own over a period of months.

One study found that male breast cancer is on the rise, with a 25% increase over the 25 years from 1973 to 1988. But it's still rare. It's unclear whether the reported rise means the disease is slowly becoming more common, or whether men better understand the symptoms and report their symptoms, leading to diagnoses that might have been missed in the past.
If you notice any persistent changes to your breasts, you should contact your doctor. Here are some signs to watch for:
a lump felt in the breast
an inverted nipple
nipple discharge (clear or bloody)
sores on the nipple and areola (the small ring of color around the center of the nipple)
enlarged lymph nodes under the arm
It's important to note that enlargement of both breasts (not just on one side) is usually NOT cancer. The medical term for this is gynecomastia. Sometimes the breasts can become quite large. Non-cancer-related enlargement of the breasts can be caused by medications, heavy alcohol use, weight gain, or m...
When the doctor told Mike Singer in 2010 that his biopsy had tested positive for breast cancer, he turned to his wife with an expletive and a request for an explanation.
How could a man have breast cancer?
Along with the shock that every cancer patient feels on hearing the words, “You have cancer,” Mike was in disbelief that he could have a “woman’s disease.” Although he knew he had a family history of the disease because his sister Joanne had died of metastatic breast cancer two years earlier, Mike hadn’t worried when he first noticed a lump near his nipple.
He didn’t even mention the lump when he saw the doctor for a check-up. At a follow-up visit, he thought to mention that he had had a lump for several months. As soon as the doctor felt the lump the size of a pencil eraser, he sent Mike for a needle biopsy. That biopsy was unsuccessful, so a surgica...
