I just received the result of a biopsy: it gave lichen planus, but the doctor who accompanies me is on vacation and only comes back in February, I've done some research on the internet and I'm a little nervous because I saw that it may be a pre-cancerous disease. Am I at risk of getting cancer? How serious is this disease?
Expert answer:

Lichen planus is a benign disease of chronic inflammatory skin, in very rare cases chronic and ulcerated can evolve after many years for a skin cancer.
