Above: skin cancer can often appear as bumps that won't go away or rough and scaly patches
4. A sore or spot that won’t go away
Some skin cancers cause pinkish or reddish bumps that look a lot like pimples, but unlike a pimple, the growth doesn’t go away over time. Others can cause sores or ulcers that are resistant to healing, so if you have a sore or pimple that refuses to go away, book a spot check to be sure it’s nothing to worry about.
5. Scaly patches
Some types of skin cancers cause patches of skin to feel dry, rough, or scaly when touched. Sometimes these patches may be discoloured, but not always. If an area of skin stays rough and scaly even after application of moisturising products, it could be skin cancer.
Alternatively, it could be a lesion called an actinic keratosis (AK), which can be a precursor to squamous cell carcinoma. AKs tend to appear in areas of the body that have been exposed to the sun, including the scalp, and they become more common with age.
Either way, if you have a dry, rough or scaly patch on your skin that doesn’t go away over time, it would pay to get it checked professionally.
