After a skin cancer: preventing the next one
One skin cancer means a higher risk of another, and a clear prevention plan.
Having one skin cancer is the single strongest predictor of developing another, which makes the period after a Mohs procedure the ideal moment to commit to prevention and surveillance.
The two pillars are protection and monitoring. Protection means rigorous, daily, broad-spectrum sun protection, sunscreen, protective clothing, hats, shade, and avoiding peak sun and tanning, because cumulative ultraviolet exposure drives the great majority of these cancers. Monitoring means regular full-skin examinations by a dermatologist on a schedule they recommend, often every six to twelve months after a skin cancer, plus self-checks for new, changing, or non-healing spots between visits. For an independent overview, see Sun protection and skin cancer prevention.
For patients with extensive sun damage, a dermatologist may also treat precancerous lesions (actinic keratoses) before they progress. The encouraging framing is that skin cancer surveillance works: most subsequent cancers, caught early through regular checks, are even simpler to treat than the first. Treating a Mohs procedure as a prompt to build lifelong sun protection and a check-up routine is the most valuable thing a patient can do for their long-term skin health.

A few principles hold across skin cancer care. The right plan is the one matched to the tumor type, its location, and your individual risk, not a one-size-fits-all rule. For cancers on the face and other sensitive areas, margin checking and tissue conservation matter most, which is where Mohs surgery earns its reputation. Ask why a given approach fits your specific lesion before any treatment begins.
Outcomes also depend on realistic staging and good aftercare. A careful consultation should set out the expected timeline in plain terms, name the recovery, explain how the wound will be repaired, and describe the plan if a side effect appears. Final cosmetic results are best judged over months as the skin remodels, and steady, sun-protected scar care helps the repair settle.
