Skin cancer symptoms may include sores that don’t heal, expert warns

Skin cancer is considered one of the most common cancers in the world, with 46 new melanoma cases appearing every day, according to Cancer Research UK.

Just like with any type of cancer, early detection is key as it can improve treatment outcomes and prognosis.

“That’s why it’s important to be aware of the signs and symptoms, including the lesser-known changes to look out for,” said Denis Kinane, a leading scientist and founder of Cignpost.

Based on the position of this cancer type, the tell-tale signs can be spotted with your eyes.


Sores can be a red flag, especially if they don’t heal within four weeks or have an abnormal appearance.

Kinane explained that you should also watch out for sores that are painful, itchy, bleed, crust or scab.

He added: “Spots or lesions that ooze and bleed without being picked, can [also] be signs of skin cancer


An appearance of a new mole or a change in an existing mole could also point to skin cancer.

Kinane said: “People should also be on the lookout for changes in the size, shape, or colour of moles.  

“Don’t forget to check your whole body regularly including the soles of the feet, palms of the hand and under the nails.” 

While melanoma, which is a type of skin cancer that can spread to other areas of the body, commonly develops in areas of the skin that are regularly exposed to the sun, such as the face, neck, and arms, it can also crop up in other places.

“Look for changes in your skin’s appearance, texture, or sensation, regardless of whether or not it’s an area that’s typically exposed to the sun,” the expert added.

While these signs are not a guarantee that you have skin cancer, “they should not be ignored”, according to Kinane.

He said: “Although some people may notice these symptoms, others may overlook them or delay getting these checked, delaying treatment.”

The NHS recommends seeing a GP if you have any skin abnormality, such as a lump, ulcer, lesion, skin discolouration or changes in your moles.

The good news is that there’s plenty you can do to reduce your risk of skin cancer developing in the first place.

Kinane added: “Wear protective clothing, apply sunscreen, and avoid direct sunlight during peak hours whenever possible.

“By taking proactive steps to protect your skin, examining your skin regularly, and seeking medical attention as soon as you notice any unusual changes, you are taking an active role in your own skin health.”
