Lancet Digital Health study: face-photo AI estimates cancer survival risk
A Lancet Digital Health study says Mass General Brigham's FAHR-Face, trained on more than 40 million face photos, can estimate cancer survival risk from one photograph.
A Lancet Digital Health study reports that a model trained on more than 40 million facial photographs can estimate a cancer patient's survival risk from a picture of their face. Mass General Brigham researchers built the system, called FAHR-Face. It has two tools: FAHR-FaceAge, which estimates biological age, and FAHR-FaceSurvival, which predicts survival directly.
According to the paper, FaceSurvival was fine-tuned on 34,363 patient photographs, and the highest-risk quartile had more than triple the mortality of the lowest (adjusted hazard ratio 3.23; p<0.0001). Scientific American reports that in a test group of 3,820 patients, 64 of the 122 with the highest risk score died within 90 days of the photo. FaceAge had a mean absolute error of 5.1 years on public datasets. Among US radiotherapy patients, those who looked five or more years older than their age had a 21% higher risk of death over an average four-year follow-up, according to the Guardian.
The paper says the models generalize across age, sex, race and cancer subgroups. Scientific American notes the survival model was trained on a majority-white Boston-area population, and bioethicist Matthew Liao warns that insurers and employers could misuse it.
My take: a hazard ratio is not a clinical decision. The coverage gives no head-to-head against a clinician simply looking at the patient, and that is the eval I want before anyone calls this a tool rather than a result.

Meanwhile at the anchor desk
A patent pending on face health algorithms, more than 40 million photos and a Lancet paper? Mass General Brigham is holding an asset, darling, and every insurer on earth just sat up straight.
No repo, no price per token in the coverage. Not much here for my usual benchmarking routine. Liao's insurance point is the part I would keep an eye on.
