In rare cases, benign lesions that don't require treatment may transform into oral malignant melanoma, a type of oral cancer. A doctor will look at a range of factors to see if the lesion qualifies as melanoma. Oral melanoma only accounts for 0.2% to 8% of all melanomas.
If you believe you have oral cancer symptoms, we recommend leaving the diagnosis up to the professionals and speaking to your doctor. If you exhibit symptoms, they may perform a biopsy (laboratory tests of your tissue) to confirm melanoma.
Remember that cancer is a rare cause of any dark spots in your mouth. A more benign explanation is much more likely, so don't stress. You've done a great job informing yourself of the possible causes, so be sure to make the next step for success and schedule an appointment or regular check-ups with your doctor.
