Skin cancer can appear on the tongue, the inside of cheeks, roof of the mouth, gums and lips. “Lips get sun-damaged as people forget to put sunscreen on them, so if a sore or ulcer pops up on your lips and it cracks, bleeds, or changes shape or colour, get it checked,” says Creeper.
Whitish sores, however, are most likely cold sores caused by the herpes simplex virus (HSV). Around 90 per cent of adults have been exposed to the HSV and a third of those experience cold sores.
A cold sore breakout can be triggered by a chest infection or flu, stress, the sun or wind. They usually clear up on their own but antiviral creams applied as soon as the area begins to tingle may help them to heal faster. #
