For how we live.
US guidance recommends mammography from 40. A Canadian review of the same randomised evidence put the benefit at 0.27 fewer breast cancer deaths per 1,000 women aged 40-49 over ten years.
In a trial of 1,643 men, prostate cancer killed 3.1% of the monitored group and 2.2% of the surgery group — a difference the trial could not distinguish from chance. Metastases were twice as common.
That is the 23-year result from the largest randomised trial. A 2026 Cochrane review of 789,086 men rates the mortality benefit moderate-certainty and the harms largely unmeasured.
A review of Paige Prostate Detect and Ibex Prostate Detect finds the tools mainly help less-specialized pathologists, and warns performance shifts when a tool meets a new population.
A linked-registry cohort of New South Wales residents from 2001 to 2018 finds cancer risk in people with intellectual disability inverts with age — higher when young, lower after 50.
A trial across five Chinese hospitals found remote robotic urological surgery non-inferior to local surgery. The sample is small, the surgeons were experts, and the network never failed.
In 105,260 people followed for 7.6 years, higher intakes of sorbates, sulfites, nitrates and acetates tracked with modestly higher cancer incidence. This is an observational study of self-reported diets.
A draft-reporting model cut documentation time 15.5% across 23,960 radiographs without changing report quality. A separate reader study found AI assistance raised prostate MRI accuracy by 3.3 percentage points.
