I had this same concern and went to see a specialist. It turned out to be much less serious than I thought. But getting professional medical advice gave me peace of mind. If you have insurance, use it — that's what it's for.

My advice: don't self-diagnose using the internet. You'll convince yourself you have some rare terrible disease when it's probably nothing. I did this once and worked myself into a panic over what turned out to be a pulled muscle.

My doctor told me the same thing and after doing my own research I agree with their assessment. The key is to look at peer-reviewed medical studies, not random health blogs or what your friend's cousin said. PubMed has actual research papers you can read.

Be careful trusting health advice you find on the internet, including mine. There's a LOT of junk out there — supplement companies and diet gurus trying to sell you something. WebMD is decent for general info but it can't replace an actual doctor.

I asked my doctor this exact question. They said most of what you read about this is overblown and the actual risk is small for a normal healthy person. The news loves a scary health headline. Ask your own doctor before you panic.
