While most ulcers are harmless and clear up within one to two weeks, radiation oncologist Dr Jiri Kubes of the Proton Therapy Center warns that any ulcer persisting longer than three weeks could be a sign of something more serious, such as mouth cancer. “Ulcers inside the cheeks, lips, or on the tongue are frequent and rarely dangerous, but because they’re so common, persistent ones can easily be overlooked,” explains Dr Kubes.https://gloucestershiredaily.co.uk/oncologist-urges-vigilance-the-three-week-rule-for-mouth-ulcers-could-signal-cancer/Wed, 27 May 2026 11:05:51 +0000https://gloucestershiredaily.co.uk/oncologist-urges-vigilance-the-three-week-rule-for-mouth-ulcers-could-signal-cancer/Mouth ulcers are a common annoyance often dismissed as stress or fatigue, but a radiation oncologist warns they shouldn’t be overlooked if they persist. Dr. Jiri Kubes from the Proton Therapy Center explains that while most ulcers heal within one to two weeks, any that linger beyond three weeks warrant medical evaluation. “Ulcers frequently appear on the inside of the cheeks, lips, or tongue and usually resolve quickly,” says Dr. Kubes.
