Okay, I am no expert, but I have had stage 2 Melanoma from a skin tag on my right arm.
The important thing is to go see a Doc ASAP.
To be honest, I couldn`t see the tag and didn`t notice it until I tore it on a truck door at work.
Lucky for me, I saw a dermatologist, right away.
I had a biopsy.
I got a suggestive result. It was melanoma and another elective operation was suggested by a plastic surgeon.
I had the operation and the results were good.
No sign of cancer anywhere and just a simple check up twice a year to prevent anything serious.
I need to see a dermatologist every six months.
Great news, steep learning curve.
I believe something caused the melanoma. But I can`t prove it.
But hopefully you can find out if you have anything wrong with your skin tag, if it looks strange, by simply reading the article below.
Again, I am not a doctor and I am not even giving advice.
I suggest you read the article below for peace of mind.
P.S. You are most likely fine, I am a rare bird, but I am glad I found out in time.
