been a year and a half for me (I started a thread then which is now closed)- and still no progress. Didn't show up on mamogram or sonogram. could not do an MRI because I cannot lie face down or get the gladonimium enhancement. After all the palpation a yea r ago, it started hurting and has not stopped. hurts frequently. Have an appt. with another doc, but just a gyn, not a breast surgeon in august. we'll see what she recommends. I'm not really sure if tis grown- I've left it alone in hopes the pain would stop. have lots of medical stuff going on and lump removal would be difficutl for me. I was supposed to go back every 3 months to the breast surgeon fo rclose followup-but did not. I hated the place- a cancer center that used these weird pagers in lieu of calling a persons name. just hated the place and now currently i'm not in that city anyway. I'm 48.
If you have dense breasts (and many women do) you might ask about a Breast MRI which tends to pick up abnormalities better under these circumstances. You might also consult a Surgeon and have him/her review your films and examine your breasts and get an opinion there. I don't think I would feel comfortable not knowing either. Keep looking ....
