What should you know about black spot in roof of mouth cancer?

Dark areas can result from normal pigment, a small injury or blood blister, irritation, medicines, dental materials, infection, or a pigmented growth. A dentist, oral medicine clinician, or ear, nose and throat specialist can assess features that a photograph cannot show.

The clinician will consider when the spot appeared, whether its border or colour is uneven, whether it is raised or ulcerated, and whether it feels firm. Pain, bleeding, numbness, difficulty swallowing, a neck lump, or a nearby tooth or denture problem provide additional clues.

Mouth cancer may present as a patch, sore, lump, or area that does not heal, and some oral cancers can be pigmented. Many non-cancerous conditions can look similar, so visual inspection alone cannot confirm or exclude cancer.

Book a dental or medical examination if the area is unexplained, persists, or changes. Avoid scraping or applying caustic home remedies. If possible, note the date you first saw it and take a well-lit photograph for comparison without delaying care.

An examination may include the whole mouth and neck. If the cause remains uncertain, the clinician may recommend referral or a small tissue sample. Treatment is based on the diagnosis; surgery or radiotherapy is considered only when appropriate for the confirmed condition.

Arrange prompt review for a spot that enlarges, develops irregular edges, bleeds without a clear injury, becomes an open sore, or is accompanied by persistent mouth pain, numbness, swallowing difficulty, voice change, unexplained loosening of a tooth, or a neck lump. Seek urgent help if swelling interferes with breathing or swallowing saliva.

You might ask what non-cancerous causes fit the appearance, whether the spot should be photographed or measured, when it should be rechecked, whether specialist assessment is needed, and what a biopsy would involve.
