Unfortunately I developed a lot of bad habits over a short term of a period.but my question is regarding my bottom lip it s pink I can t tell if it infected because it does really seem so it s a little area in the middle it s pink where the rest is more red it s natural color. It started after a while back like 2 years ago it gets smaller but then it comes back. I thought it was because I lacked vitamin c and other Important vitamins. I have a horrible diet I don t really get allot of vitamins but what would be the cause of this situation could this be early stages of cancer.also I picked up a habit of smoking around the same period.
