Can biting nails cause cancer?

I developed a really severe nail bed infection from biting them, which required a minor surgical procedure to drain. It is not something to take lightly. If you have any non-healing wounds or lumps on your fingers, please see a doctor.

No, nail-biting does not cause cancer. It just causes bacterial infections and damages your teeth.

Actually, it is highly unlikely to cause cancer, yaar. But you can get some really nasty stomach bugs from all the dirt under your nails. Just try using a bitter nail polish to quit.

I was actually looking this up because I have a bad habit of biting my nails. Turns out, unless there's a chronic, untreated infection or major tissue damage over years, it doesn't cause cancer. But yeah, the germs are still gross!

Bro, instead of biting your nails, keep your mouth busy with some peanuts or chips! It is a much tastier way to handle the stress, and your fingers will thank you.
