Reminders for a monthly skin self-check: what to look for and when to act

Melanoma is among the most dangerous skin cancers, but also one of the most detectable when found early. The 5-year survival rate for stage 1 melanoma is over 98%; for stage 4 it drops significantly. The difference between early and late detection is often whether someone was checking regularly. A monthly self-examination — looking systematically at skin across the body, including scalp, soles of feet, and between fingers — is a standard recommendation from dermatology organisations. The challenge is building and maintaining the habit. A monthly phone call reminder is a simple, reliable prompt.

What a skin self-check involves

A systematic skin self-check uses the 'ABCDE' framework: Asymmetry (one half doesn't match the other), Border (irregular, ragged, or blurred edges), Colour (more than one shade, or uneven distribution), Diameter (larger than 6mm, roughly the size of a pencil eraser), and Evolving (any change in size, shape, colour, or a new symptom like itching or bleeding). A spot that meets any of these criteria warrants prompt GP review.

The check should cover all skin, not just visible areas. Use a full-length mirror and a hand mirror to examine the back, scalp (use a comb to part the hair), between toes, and the soles of the feet — areas that are easy to overlook and where melanomas are sometimes found in people with no history of sun damage.

Setting up a monthly skin check reminder

Create a recurring monthly reminder on a fixed date — the first Sunday of each month works well. The message should prompt a complete check, not just a quick glance: 'Monthly skin check — use both mirrors, check scalp, soles, and between fingers. Note any new or changed spots.' A structured message means you know exactly what you're doing when the call arrives.

If you have a mole map, photography tool, or dermatology app that tracks changes over time, add a reminder to update it during the same session. Year-on-year comparison photos are among the most useful tools for detecting slow-growing changes.

When to see a GP without waiting for the next reminder

Set a separate note in the reminder message: 'If any spot is new, changed, itching, or bleeding — see your GP this week, don't wait for the next check.' The reminder creates a habit; the habit creates the context for noticing something that needs prompt attention.

People with fair skin, a history of sunburn, more than 50 moles, a personal or family history of melanoma, or who use sunbeds are at higher risk and may be advised to check more frequently or have professional skin checks. Always follow the guidance of your GP or dermatologist. This information is for general awareness and does not substitute for medical advice.
