Cyst Aspiration

Breast cysts are fluid-filled sacs inside the breast that may cause some discomfort but are generally not cancerous. When a breast lump hurts or causes concern, physicians can aspirate it, or drain the fluid, to rule out cancer and alleviate the soreness.

If the cyst contains watery fluid and disappears once it has been drained, no further tests are required. If it contains bloody fluid, your doctor may perform a biopsy to look for cancer cells.
