Mammograms are commonly recommended every 1–2 years for women starting around age 40.

Colorectal cancer screening

Screening is generally recommended for adults 45–75, by colonoscopy or stool-based tests.

Bone density testing is generally recommended for women 65+ and younger people with risk factors.

Lung cancer screening

Yearly low-dose CT may be recommended for adults 50–80 with a significant smoking history.
