Benign calcifications are harmless. You won't need treatment or other tests.
''Probably benign'' calcifications have a less than 2% chance of being cancer. Typically, they're monitored every 6 months for at least a year. After that, your doctor will recommend a routine mammogram once a year.
With "suspicious'' calcifications, your doctor may recommend a biopsy -- a small amount of breast tissue is removed and sent to a lab. If they find that it's cancerous, you may need surgery to remove the breast along with radiation or chemotherapy to kill any remaining cancer cells.
