The most important melanoma warning sign — the "E" for evolving — is a comparison over time. You can't judge whether a mole has changed unless you have a reliable record of what it looked like before. Memory isn't that record; the human eye is poor at recalling fine visual detail months later.
This guide gives you a simple, repeatable system for tracking your moles: how to build a photographic baseline, how to run a monthly self-exam, where apps and professional mole-mapping fit, and exactly what kind of change is worth a call.
Have Questions?
Ask questions and get clear, trusted answers — instantly.
•Regional overview shots. Photograph each body area — face, chest, abdomen, each arm, upper and lower back, each leg, feet — so you can spot a new mole, not just changes to known ones.
•Close-ups of your atypical moles and any that your dermatologist flagged, with a ruler or coin in the frame for scale.
For the photos to be comparable, keep these consistent every time:
•Same lighting (bright, even, no harsh shadows — daylight near a window works well).
•Same distance and angle; fill the frame but stay in focus.
•Plain background, flash off if it washes out color.
•Use anatomical landmarks (a scar, a freckle cluster) so you can relocate the exact mole later.
Date each set, store it in a dedicated album organized by body region, and repeat every 3 months — or on whatever schedule your dermatologist recommends.
Apps and Professional Mole-Mapping
Consumer mole-tracking apps are handy for keeping photos dated, organized, and on a reminder schedule. Use them for that. Do not rely on an app's automated "risk score" to decide whether a mole is safe — those tools are not a substitute for a clinician.
If you have many atypical moles, the most accurate tracking is done in the clinic: total-body photography plus sequential digital dermoscopy, where the dermatologist re-photographs selected moles under magnification and compares them frame by frame. This approach helps find melanomas earlier while removing fewer benign moles. See what a dermatologist looks for when examining atypical moles.
A Monthly Self-Exam Routine
Pick the same date each month and work through it the same way:
•Bright room, full-length mirror, and a hand mirror for hard-to-see areas.
•Go head to toe in a fixed order: scalp and face, neck and ears, chest and abdomen, both sides and underarms, arms and hands including between fingers and under nails, back and buttocks (hand mirror), legs, then soles and between the toes.
•Have a partner check your back, rear scalp, and other blind spots — or compare with your overview photos.
•Use a body mole map (a simple front/back diagram) to note the location of moles you're watching.
What Counts as a Change Worth Reporting
Put the new photo next to the old one and look for:
•A clear increase in size, or a change in shape or symmetry.
•New colors — especially black, blue-gray, red, or white — or color spreading unevenly.
•A border that has become ragged, notched, or blurred.
•A mole becoming raised, firm, or developing a lump within it.
•New symptoms: itching, tenderness, bleeding, oozing, or crusting.
•A brand-new mole after about age 40, or any mole that now stands out from your others.
Any of these deserves a call within a few weeks. The warning signs guide goes deeper on interpreting them.
Keep a Simple Log
Alongside the photos, keep a short dated note: which moles you're watching, where they are, and anything you noticed this month. Bring both the log and the photos to every dermatology visit — it lets your dermatologist compare against your record, not just theirs, and makes the appointment far more productive. This record also supports the interval planning in how often should I get my skin checked?
Which specific moles do you want me to photograph and watch closely?
How often should I redo my baseline photos?
Do you offer total-body photography or digital dermoscopy for my situation?
What's the best way to send you a photo if I spot a change between visits?
Can you mark my watched moles on a body map I can take home?
Conclusion
Good mole tracking isn't complicated: a dated set of consistent baseline photos, a fixed monthly self-exam, and a habit of comparing new against old. That's what turns the vague worry of "is this mole different?" into a clear yes or no.
Bring your photos and notes to every appointment. The combination of your record and your dermatologist's is the most reliable early-warning system there is.
