Cyst Aspiration

Cysts are fluid filled sacs within the breast. These sacs form when normal milk-producing glands enlarge. The cause of this enlargement is not definitely known but is very likely related to an imbalance between the normal production and absorption of fluid. Breast cysts may be solitary but are most commonly multiple and can vary in size from microscopic to larger … Read More
