Indications for screening for skin cancers in the general immunosuppressed populations

Who is at risk

Immunosuppressed patients (particularly solid organ transplant recipients) require structured, more frequent skin cancer screening than the general population, given their substantially elevated risk, particularly of squamous cell carcinoma
Skin cancer risk begins rising within the first few years post-transplant and continues to increase with cumulative immunosuppression duration - screening needs are lifelong and intensify over time, not a one-off assessment

The mechanism (reduced immune surveillance of UV-damaged and HPV-infected keratinocytes) means risk is cumulative and progressive with ongoing immunosuppression exposure, justifying an intensifying rather than static screening approach over the years post-transplant

Baseline full skin examination before or shortly after transplant, with regular follow-up skin checks (typically annual at minimum, more frequent - 6-monthly or more often - with increasing time post-transplant or once a first skin cancer has occurred, since prior skin cancer strongly predicts further lesions)
Patients should also be educated in self-examination between formal reviews, given the volume of skin surface area to monitor and the practical limits of clinic-based review frequency alone

Screening indications intensify with: longer time since transplant, prior skin cancer diagnosis, fair skin type, and high cumulative sun exposure history - risk stratification should inform individualised screening frequency rather than a single fixed interval applied to every immunosuppressed patient
Early detection through structured screening allows earlier, simpler treatment (versus later detection of more advanced, harder-to-treat disease) - the central rationale for intensive screening in this population
Screening frequency should increase, not remain static, with time since transplant and particularly after a first skin cancer diagnosis - this progressive intensification, rather than a fixed annual check regardless of history, reflects the genuinely cumulative and progressive nature of the risk

Solid organ transplant recipients, squamous cell carcinoma (the disproportionately elevated risk), prior skin cancer as a risk factor for further lesions, self-skin-examination education
