Is skin cancer screening done with a dermatoscope?

A dermatoscope is a handheld viewing device that magnifies a lesion and uses illumination to reveal structures that may not be clear to the unaided eye. The clinician may examine one mole, several changing marks or the skin more broadly, depending on your history and reason for attendance.

The device supports assessment; it cannot by itself confirm or exclude every skin cancer. The clinician combines its appearance with changes over time, symptoms, location, personal history and examination of nearby skin. If a lesion remains concerning, a biopsy may be recommended so tissue can be examined.

Tell the clinician about a new or changing mark, itching, bleeding, crusting, pain, previous skin cancer, significant sun exposure and relevant family history. Do not cover a lesion with makeup or a thick dressing before the appointment if it can be avoided, and bring information about earlier photographs or assessments.

During the visit, point out areas you have noticed rather than relying on a full examination to find every change. Ask how the lesion will be monitored if immediate sampling is not advised, and keep any recommended photographs or follow-up date.

Arrange prompt assessment for a mark that is changing in size, shape or colour, or one that bleeds, crusts, repeatedly itches or does not heal. Do not wait for a routine check if a lesion is rapidly changing or newly symptomatic; the urgency depends on the lesion's features, not on how common skin marks are.

Which marks need dermatoscope examination? What features make you recommend monitoring, photography or biopsy? When should I return, and which changes should make me contact you sooner?
