If you feel a lump in your breast, your first thought may be that you have breast cancer. Fortunately, most breast lumps are benign, meaning they’re not cancerous.
Breasts are complex structures, filled with glands, tissue and fat. It’s relatively common to develop a breast lump, cyst or tumor in your breast. This is known as benign breast disease. While these breast conditions aren’t cancerous or life-threatening, they may increase your risk of developing breast cancer in the future.
