A skin-check offer often sounds as though a rule stands behind it. This article sets that impression beside what one independent guideline body, the U.S. Preventive Services Task Force, actually concluded.

What the U.S. Preventive Services Task Force concluded

For adolescents and adults who do not have signs or symptoms of skin cancer, the U.S. Preventive Services Task Force found the current evidence insufficient to assess the balance of benefits and harms of visual skin examination by a clinician to screen for skin cancer.

The word "insufficient" is not the same as "no". It says the evidence has not settled the balance of benefits and harms for people without signs or symptoms.

What the patient summary adds

The National Cancer Institute publishes a patient summary on skin cancer screening. It is a companion read from a second independent source.

What an exam looks for and what the task force weighed

An offer that says a skin check can find skin cancer is describing what an exam looks for. The task force statement is about something different, which is whether screening people without signs does more good than harm. The American Academy of Dermatology's skin cancer pages cover symptoms, diagnosis and causes, so they speak to a reader who has already noticed something.

What the Skin Cancer Foundation says about annual exams

The Skin Cancer Foundation has a page on annual exams. Read it as one organisation's position, set next to the task force's statement and not in place of it.

The second version of the National Cancer Institute summary

The National Cancer Institute also lists a second version of the same material, titled Skin Cancer Screening (PDQ). Reading both shows how the same subject is laid out for different readers.

Checking who an offer's recommendation covers

Before you accept an offer, check whether the recommendation behind it covers people who have no signs or symptoms. Whether a spot you can see deserves a closer look is a decision for a clinician who examines it.
