It might be a cancerous, it might not be.
I went to see my dentist early in my quit. I had a small white spot where I had held my dip. I hadn't even noticed it. It was pretty light, and pretty small. My dentist called it leukoplakia.
He didn't seem too alarmed, so I didn't get too alarmed, but I did schedule a follow-up visit. I can't remember if it was one week later or two weeks later. He took a pic of the spot so he could make a comparison. If the spot grew, and was thicker, it may have been precancerous.
The day of my follow up, I looked for the spot, and couldn't find it. I almost skipped the appointment, but I ended up deciding they he was the medical professional, and I wanted to put my mind completely at ease.
The spot was almost completely gone, only a very faint shadow remained. What I did find out from that experience is that my gums are permanently receded where I held my dip. They are gone, and will never grow back.
My advice is for you to see your dentist as soon as you can get in.
Stay active here at KTC. Post roll every day. Stay quit.
If you find out that your spot is harmless like mine was, don't use that as an excuse to go back to the can. People do get cancer and lose their tongues and jaws and die from it.
It's nasty, disgusting, and you stay a slave to the can.
