Hello, I am concerned because a few months ago, I noticed that if I squeeze my nipple, I get a clear to milky white discharge from my right nipple. It seems to be coming from one duct only. My OB/GYN ran blood work to check for hypothyroid and increased prolactin levels - both negative. They also did lab work on the fluid from my nipple - negative. They have also ordered a mammogram which I have not had completed yet. I take 25 mg of Metoprolol SUCC ER/day. I also take Ibuprofen prn and Iron supplements until recently for anemia (prob due to heavy, prolonged periods/vegetarian diet). I am very afraid because I have read that nipple discharge from one breast and from one duct can be a red flag for breast CA.
