Hi AlwaysWorried! I was just in your position about 3 weeks ago. I totally understand and was very scared also. At my yearly gyn appt, my dr. felt what he thought was cyst. However, I could not feel it, nor could my husband who is a physician. I'm 38 and had never had a mammogram, so my dr. sent me for a DIAGNOSTIC mammogram and an ULTRASOUND! Agh, I was freaked. I had the mammo and then the ultrasound and the radiologist came in the room, was pretty uncaring, and said that while my ultrasound was clear, there was more "white" in my right breast than my left. I have fibrous, dense breasts and fibrous tissue shows up as white, but so does cancer. He was concerned because my right breast definitely had more white, and that's where my dr. thought the "cyst" was, which BTW, never showed up on the ultrasound. I guess symmetry is good, and since there was more white on my right breast than my left, and since I'd never had an ultrasound to compare it to, the radiologist was concerned. So, he recommended an MRI. Waiting for that was the longest and worst week of my life. I seriously went nutty.
Anyway, I had the MRI, doped myself up on 2 xanax so I could stay calm while it was done. They told me it'd take a few days to get the results back. After the MRI was done, they said "The radiologist will call you this afternoon." HOLY CRAP. Way to freak a girl out! I knew it would be bad news after hearing that. I also knew that breast MRI's have a high number of false positives so I was totally expecting a biopsy. Imagine my surprise when they called my husband later that afternoon and said that I have "busy breasts" and lots of fibrous tissue, but that's it. WHEW! They recommend I have another MRI in a year and then after that go back to regular mammograms.
Like I said, my husband is a physician (family practice) and he said that breast cancer is the number one thing that doctors are sued for, so they are EXTRA cautious.
I don't know what state you live in, but I do know that some states have laws that when a woman has very dense breasts, they have to send them for an MRI or ultrasound. Hmm, I have a friend in Connecticut and I think she said that is the law there. Don't know where you live, but that could be the reasoning too.
I think you will be just fine. It is a good precaution. When do you get your MRI? Please keep us posted! ((((hugs)))
