Wombat, I have had a small pea size cyst on the inner upper quadrant of my right breast for over 20 years. I can squeeze gunk out of it. The doctor told me not to worry about it until I could no longer squeeze anything out of it. Now the stuff smells bad. What I squeeze out is a long stringy yellow stuff. I've not painted my breast yet. What do you think this is? I had a mammagram twice in 12 years and only FBD was found.
