You have a mouth ulcer that wont heal. Youve also noticed unusual bleeding or gum swelling. In rare cases, persistent oral symptoms can be an early sign of something more serious — including blood cancer. Heres what to watch for.

What is a leukaemia ulcer?

A leukaemia ulcer is not a type of ulcer in the usual sense. Its an area of tissue breakdown in the mouth that occurs because of leukaemia — a cancer of the white blood cells. When leukaemia develops, abnormal cells crowd out healthy ones, including those that help your body fight infection and repair tissue. This can allow ulcers to form, particularly on the gums, tongue, or inside of the cheeks.

How does leukaemia show up in the mouth?

Your dentist may be the first professional to notice signs of leukaemia during a routine examination. Oral signs can include swollen, bleeding gums that look spongy or purplish, persistent ulcers that dont heal within two weeks, and unexplained oral bleeding. You might also notice white patches in the mouth caused by an overgrowth of abnormal white blood cells. These symptoms often appear alongside general signs such as fatigue, bruising easily, or frequent infections.

Why you shouldnt panic — but should act

Its important to understand that most mouth ulcers, swollen gums, and oral bleeding have far less serious causes. Aphthous ulcers — also known as common canker sores — are far more likely to blame. Gum disease, vitamin deficiencies, or accidental biting can all produce similar symptoms. However, because leukaemia is a serious condition, any persistent oral symptom that doesnt resolve within two weeks should be checked by a dentist or doctor promptly.

What to do if youre concerned

If you have a mouth ulcer that has been present for more than two weeks, or if youve noticed unusual bleeding or swelling in your gums, book a dental appointment as soon as possible. Your dentist can examine the area and, if needed, refer you for further tests. Early detection of leukaemia significantly improves treatment outcomes.

Looking after your oral health

Regular dental check-ups are about more than just your teeth. Your dentist is trained to spot oral signs of many systemic conditions, including leukaemia. Attending your routine appointments means any unusual changes in your mouth can be identified and investigated early.
