Dear EV900, Cysts are fluid filled lumps. They typically occur in women in their 30's, 40s and early 50s and are most common in women approaching menopause. Usually a woman will only get one or two cysts in a lifetime, however some woman do get many cysts, and get them often. Cysts are harmless in themselves, and as long as it has been confirmed by mammogram and ultrasound that these are indeed cysts there really is no need to aspirate them. Aspiration of the cyst involves putting a tiny needle into the cyst and removing the fluid. Also if the cyst is causing pain or discomfort, aspiration of the fluid may relieve the discomfort. Cysts do not turn into cancer, but having so many cysts may make finding a cancer more difficult. Discuss with your doctor some specifics about how you will be followed regarding these cysts, you may consider seeing a doctor who specializes in breast care, to help with the management and follow up of your case.
