Melanoma is less common than other skin cancers, but it is more aggressive and more dangerous when caught late. The encouraging reality is that early detection and consistent protection dramatically reduce risk. This guide focuses on practical habits and simple checks you can actually sustain.
Melanoma originates in pigment‑producing cells (melanocytes). It can develop anywhere, including areas that do not get much sun. That is why regular, full‑body checks matter.
| Signal | What It Means | Why It Matters |
|---|---|---|
| A — Asymmetry | One half doesn’t match the other | Possible abnormal growth |
| B — Border | Irregular, jagged edges | Higher risk pattern |
| C — Color | Multiple shades in one mole | Potential change in cells |
| D — Diameter | Larger than 6 mm | Needs monitoring |
| E — Evolving | Changes over time | Most important warning sign |
A mole that changes in size, shape, texture, or sensation deserves attention. New spots after age 30 or a “mole that stands out” compared to others are worth checking.
Use sunscreen daily and treat it like toothpaste — a standard habit. Pair it with physical protection like hats and UPF clothing.
Practical Rule: Daily SPF, shade at peak UV hours, and monthly self‑checks.
These three habits cover most risk without forcing drastic lifestyle changes.
