The balance of benefits and harms cannot be determined due to limited direct evidence on effectiveness and potential harms, including unnecessary biopsies and overdiagnosis.
A task force has been criticized for not recommending melanoma screening due to lack of evidence, but dermatologists believe early detection reduces risk of death from melanoma through visual inspections. The issue highlights the need for refined standards on skin cancer screenings with potential life-saving benefits.
A recent study by researchers at Johns Hopkins finds that people with a history of nonmelanoma skin cancers still get sunburned, likely due to ineffective use of sun-protective methods. The study urges healthcare providers to better educate patients on protective skin care practices.
A new study of over 1,000 primary care melanoma screenings found no significant increase in surgical treatments or specialist referrals. The practice did result in a 79% increase in per-patient melanoma diagnoses among the most trained group, but this was not associated with an increase in dermatologist visits or surgeries.
