Skin cancer is the most common cancer diagnosed in the United States. It develops when UV radiation damages DNA in skin cells, which triggers abnormal growth. The condition is highly treatable when caught early, and regular skin checks are central to early detection. Here is more information on skin cancer, the primary prevention methods, and what patients can expect during a professional skin check:
What Is Skin Cancer?
Skin cancer develops when abnormal cells grow uncontrollably in the skin’s layers. Since UV radiation is the primary trigger, it most commonly arises in exposed areas such as the face, neck, arms, and hands. The three main types are basal cell carcinoma, squamous cell carcinoma, and melanoma; melanoma carries the highest risk of spreading to other parts of the body, making it the most dangerous.
How Is It Prevented?
UV exposure is the leading cause of skin cancer, and sun protection helps protect the skin. Applying broad-spectrum SPF 30 or higher sunscreen reduces UV exposure. Wearing protective clothing and avoiding peak sun hours further minimizes risk, as these measures limit direct contact with harmful radiation. Tanning beds emit concentrated UV radiation, so avoiding them is beneficial.
Staying aware of the skin’s baseline appearance supports early detection; changes in moles, new growths, or spots that bleed or fail to heal are warning signs. Because these changes can indicate malignant development, they warrant prompt clinical evaluation. Combining protective habits with routine professional skin checks provides a comprehensive approach to reducing cancer risk.
What Are Regular Skin Checks?
A skin check is a clinical examination a dermatologist performs to detect early signs of skin cancer or pre-cancerous lesions. Dermatologists generally recommend annual skin checks for adults, though patients with a personal or family history of skin cancer may require more frequent appointments. Individual risk factors including skin type, sun exposure history, and the number of moles present determine how often checks are needed; these factors vary from patient to patient.
Self-examinations between professional appointments also play an integral role in early detection. Patients may be encouraged to inspect their skin monthly using good lighting and a mirror; paying close attention to hard-to-see areas such as the scalp and back is beneficial. See a dermatologist promptly for any new or changing spots, as waiting for a scheduled appointment delays identifying a potentially serious condition.
What Do Skin Checks Involve?
A professional skin check begins with a thorough review of the patient’s medical history, and this includes prior skin conditions, family history of cancer, and current medications. The dermatologist then conducts a full-body visual examination, systematically assessing the skin from the scalp to the soles of the feet. The process is non-invasive and typically brief, so patients do not need to set aside much time. No special preparation is required.
During the examination, the dermatologist looks for specific warning signs using the ABCDE criteria:
- Asymmetry: One half of a mole does not match the other
- Border: Edges are irregular, ragged, or blurred
- Color: Variation in color, including shades of brown, black, red, or white
- Diameter: Spots larger than 6 millimeters
- Evolving: Any changes in size, shape, color, or new symptoms
