[|Human|] My dentist referred me to a pathologist because i have a white ulcer like lesion on one side of my gums. Is this something that i should worry such as cancer or can it be a simple canker sore. i notice it when i felt a bit of discomfort such as like having something in between you teeth and cheeks.  I brushed it and irritated the area and it bleed. no pain just irritation when i use salt and water or mouth wash.  not a smoker or tobacco user. please advised. thank you
[|AI|]  Hello, Welcome to Chat Doctor .com.  I had gone through your question I can understand your concern. White lesions in Oral cavity are not cancerous presented symptoms. Most common reasons of white lesions are;Leukoplakia, candidiasis, liken plans or any other autoimmune skin or mucus membrane disorder.  Most likely it can be either fungal infection or leukoplakia.  Oral cancers mostly present itself a non-healing chronic raised ulcer.  But you must go for histopathology to rule out any malignant lesion like leukoplakia, these lesions if not treated for many years can lead to cancer.  So you don't need to worry and hope you will be fine. Write to us in case of any further query or doubts. Regards Chat Doctor.
