Why Tracking Mole Changes Matters
The "E" in the ABCDE melanoma criteria stands for Evolution—change over time. Many melanomas are caught not because they look obviously abnormal, but because someone noticed a mole was changing. Regular photography creates a visual record that makes subtle changes visible.
Studies show that patients who regularly photograph and monitor their moles have higher rates of early melanoma detection. Early-stage melanoma has a 99% survival rate, compared to much lower rates for advanced disease.
A mole getting bigger — what growth actually means
"Getting bigger" is the single most common change people notice, and it matters for a specific reason: melanoma cells divide and expand outward or downward, so measurable growth in a mole is a direct visual signature of what's happening biologically. A benign mole normally stays roughly the same size for years — it may darken a little with sun exposure or become slightly raised with age, but the outline shouldn't be creeping outward month on month.
Use dated photos with a coin or 5mm/10mm ruler in the same frame. Widening of the border, a new bump on one edge, or a fresh dark patch inside a previously even mole are the three growth patterns dermatologists most want to see. If you can see any of those between two photos taken 4–8 weeks apart, book an in-person review — don't wait for a routine appointment. Pair this with the free AI mole checker to get an ABCDE-scored second opinion on the photo before you go.
Why one check is rarely enough
A single scan tells you about one spot, on one day. But skin changes are about patterns over time — a new mole appearing, a slow shift in shape, size or colour, or a patch that simply isn't healing. Monitoring the same spots side-by-side, week after week, surfaces the subtle changes a one-off check will always miss — and gives you a clear record to show a clinician if something needs a closer look.
