A breast lump is a swelling in the breast, tender or nontender that feels different from the normal tissue of the breast. There are many reasons for breast lumps and majority of them are not cancerous. The causes include infection, cysts, fat, abscesses, necrosis, or fibrocystic masses.
If you feel a breast lump you should have it evaluated as soon as possible. Breast lumps may be present in both males and females, but they are much more common among females.
