K.C.
It's not as bad as it seems. My doc gave me a prescription for Ativan, which really helped. And you're face down, kinda like if you're getting a massage, so I didn't feel "closed in" at all, my face was planted down on the pillow thingy and my eyes were closed. It's loud, but they give you headphones, and it's more rhythmic than annoying.
The first time I had it done, I almost fell asleep, seriously. But then in the last 10 minutes, my shoulder involuntarily jerked, and that made me really aware of my body and that I couldn't move at all. That last 10 minutes was the longest 10 minutes of my life.
I don't really remember any details about my second MRI...THAT'S how uneventful it was. And it was only a few months ago.
Unfortunately for me, my test results confirmed what the docs had already told me - DCIS or Stage 0 BC. I had a lumpectomy and 7 weeks of radiation, and now I'm on Tamoxifen. But treatment was actually very easy and now I feel more healthy than *before* the BC. My second MRI confirmed that they'd gotten it all and there was no sign of any abnormal cells left in my body. It was a real wake up call to live a healthier life, and I've found that once I made that commitment, it's been kinda easy to do.
Frankly, breast cancer changed my life for the better. I was lucky, I dodged a bullet, and I'm not going to take my health for granted anymore. It was a hard learned lesson, but one that I'm embracing fully. That was my personal experience with it.
