A breast lump is a growth of tissue that develops within your breast. Different types of breast lumps can vary in the way they look and feel. You may perceive a lump as a mass, growth, swelling, thickness or fullness.

You might notice:

• A distinct lump with definite borders
• A firm, hard area within your breast
• A thickened, slightly more prominent area in your breast that's different from surrounding breast tissue
• Other breast changes, such as redness, dimpling or pitting of the skin
• One breast that's noticeably larger than the other
• Nipple changes, such as a nipple that's pulled inward or spontaneous fluid discharge from your nipple
• Persistent breast pain or tenderness, which might increase during your menstrual period

Sometimes, a breast lump is a sign of breast cancer. That's why you should seek prompt medical evaluation. Fortunately, however, most breast lumps result from noncancerous (benign) conditions.
