Triple-Negative Breast Cancer
There are many causes of breast lumps. Some of these causes are harmless, while others can be painful and/or dangerous. Causes of breast lumps include infections, injuries, non-cancerous growths, and cancer.
Breast cancer is the second leading cause of cancer-related deaths in women in the United States. Currently, death rates from breast cancer are declining. The decline in death rates may be due to a combination of earlier detection and better screening as well as improved treatments. While most breast lumps are harmless (benign), every breast lump should be evaluated by a doctor to exclude or establish a diagnosis of cancer.
