Cancer screening by age: what to book, and when
The screenings worth booking at each life stage, matched to age and sex, and why early detection changes everything about treatment.

Why the timing matters, not just the test
Cancer screening exists to catch disease before it causes symptoms, when treatment is simplest and most effective. Screening too early wastes money on a low-risk population; screening too late misses the window it exists for. Age and sex-based guidelines aim for the point where the balance tips in your favour.
For women
Cervical screening from the mid-20s, repeated every few years, catches changes caused by HPV years before they could become cancer, one of the most preventable cancers in existence when screening is kept up. Breast screening becomes relevant from 40, or earlier with a family history; know your own normal well enough to notice a change between screens too.
For men
Prostate screening (a PSA blood test) becomes a conversation from 45, informed rather than automatic, because the test itself has trade-offs a doctor should walk you through, not a default add-on to every checkup. Family history moves that conversation earlier.
For everyone from 45
Colorectal screening is worth discussing from 45, or earlier with a family history or persistent symptoms like unexplained bleeding or a change in bowel habit that lasts more than a couple of weeks. None of these tests are pleasant to think about, which is exactly why they're worth booking on a schedule rather than waiting for a reason to feel ready.
