Canker sore, which is more commonly known by its alternate name-mouth ulcer, is a terribly painful sore that takes at least a week’s time to heal. Canker sores are the most common type of mouth ulcer and the most common places where they occur is the inside of the lip or cheek. They appear either white or yellowish and are circled by red, inflamed tissue which is warm.

Canker sores do not require extensive diagnostic procedures for confirmation. Usually the physician diagnoses canker sore by just looking at it. If the doctor thinks it could be a virus, vitamin or mineral deficiency, problem with the immune system or hormonal disorder that is causing the problem or if there is a severe breakout, he/she may take a biopsy of the area or recommend blood tests.

Sometimes, cancerous lesions may also appear as canker sores and it is during such a diagnosis that treatment becomes necessary.
