These subtle changes could be warning signs of skin cancer, a disease that affects over 170,000 people in the UK each year. As with any illness, the earlier the symptoms are spotted, the better the chances of recovery.
With this in mind, Dr. Emily Alfonsi, a skin cancer specialist from Shade Dermatology Clinic in the UK, has shared the skin changes you shouldn’t ignore.
“The skin is the body’s largest organ, and it tells a story about your overall health,” she explains. “Even subtle changes can indicate something alarming. Early detection is crucial for skin cancer and other conditions.”

The signs to look out for are:
Moles or unusual lesions
Any mole that changes in size, shape, or color, or has an irregular border, should be checked immediately.
Persistent dry patches or itching
While these symptoms may be harmless, prolonged issues could indicate eczema or even cutaneous lymphoma.
Non-healing wounds
Sores that don’t heal within two weeks could be a warning sign of basal cell or squamous cell carcinoma.
Sudden skin discoloration
Unexplained red, yellow, or black spots may indicate underlying health issues such as liver disease or melanoma.
New lumps
Pay attention to new lumps or swollen areas, especially if they bleed or scab.
According to Dr. Alfonsi, skin cancer is one of the most treatable forms of cancer when caught early. Recent studies show that over 90% of skin cancer cases can be cured when detected in the early stages.
This is why regular self-examinations and professional screenings are vital. Dr. Alfonsi recommends monthly at-home skin checks, paying particular attention to often-missed areas like the scalp, behind the ears, and under the fingernails.
“If you notice anything unusual, don’t hesitate to seek expert advice,” she adds. “A quick visit could put your mind at ease or save your life.”
The UK’s National Health Service (NHS) states that ultraviolet (UV) radiation is the most common cause of non-melanoma skin cancer.
To reduce your risk when outdoors:
– Avoid sun exposure during the hottest part of the day (11 am to 3 pm)
– Cover up with clothing, a wide-brimmed hat, and sunglasses to protect against UV rays
– Use sunscreen with a sun protection factor (SPF) of at least 30 and a minimum 4-star UVA rating – reapply frequently
– Ensure babies and children are protected from sunlight – their skin is far more sensitive than adults’
