Skin cancer screening is essential for early detection and treatment. In the UK, the NHS recommends regular checks for moles and skin changes. Look for asymmetry, irregular borders, different colours, and larger diameters in moles, which may indicate possible skin cancer. If you notice any unusual changes, it's important to consult your GP. They may refer you to a dermatologist for further evaluation. While skin cancer is often associated with sun exposure, factors like skin type and family history also play a role. Regular self-examinations and professional screenings can significantly increase the chance of successful treatment.
