How Can You Protect Yourself from Skin Cancer?
Use broad-spectrum SPF 30+ sunscreen daily, seek shade during peak UV hours (10am-4pm), wear protective clothing including wide-brimmed hats and UV-blocking sunglasses, avoid tanning beds, and perform monthly skin self-examinations. These combined strategies can prevent the majority of skin cancers.
The Australian 'Slip-Slop-Slap-Seek-Slide' campaign (slip on a shirt, slop on sunscreen, slap on a hat, seek shade, slide on sunglasses) provides a comprehensive framework. A landmark Australian RCT demonstrated that regular sunscreen use reduced melanoma incidence by 50% and squamous cell carcinoma by 40% over a 10-year period. Sunscreen should be applied as part of your daily morning routine, not just for beach days — cumulative daily UV exposure drives most skin cancer risk.
Protective clothing with Ultraviolet Protection Factor (UPF) ratings provides reliable physical sun barrier. A standard cotton t-shirt provides only UPF 5-10, while UPF-rated clothing provides UPF 30-50+. Wide-brimmed hats protect the face, ears, and neck — areas with highest skin cancer incidence. Window film or tinting on car windows blocks UVA rays during driving, which is a significant exposure source.

How Do You Detect Skin Cancer Early?
Use the ABCDE rule during monthly self-examinations: Asymmetry (one half doesn't match the other), Border irregularity (ragged or blurred edges), Color variation (multiple colors or uneven distribution), Diameter larger than 6mm (pencil eraser size), and Evolving (changing in size, shape, color, or symptoms). Any lesion meeting one or more criteria should be evaluated by a dermatologist.
Perform a systematic monthly self-exam using a full-length mirror, hand mirror, and good lighting. Check your entire body including scalp (use a hair dryer to part hair), between toes, soles of feet, nail beds, and genital area. The 'ugly duckling' sign — a mole that looks different from all your other moles — is a useful additional detection tool. Photograph suspicious moles for comparison over time.
Dermoscopy (dermatoscope examination) by a trained dermatologist significantly improves diagnostic accuracy over naked-eye examination. Total body photography combined with sequential digital dermoscopy is recommended for high-risk individuals (multiple atypical moles, personal or family melanoma history, genetic predisposition). Early-stage melanoma (in situ or thin <1mm) has a nearly 100% 5-year survival rate, compared to approximately 30% for Stage IV melanoma.
