Cancer Screening Schedule by Age
The appropriate cancer screening schedule changes with age, sex, and risk factors. Here is the current consensus schedule from the American Cancer Society, United States Preventive Services Task Force (USPSTF), and American College of Physicians for average-risk adults.
Ages 21-29: Cervical cancer screening (Pap smear every 3 years for people with cervix); skin cancer awareness (monthly self-exam); testicular cancer awareness for men (monthly self-exam for ages 15-35). Ages 30-39: HPV co-testing with Pap every 5 years (or Pap alone every 3 years) for cervical screening; breast cancer risk assessment and clinical breast exam; cholesterol and blood pressure screening; type 2 diabetes screening if overweight.

Ages 40-49: Annual mammography recommended for women with average breast cancer risk from age 40 (ACS recommendation; USPSTF recommends from 40-44 as individual choice, mandatory from 45); colorectal cancer screening starting at 45 (FIT annually, Cologuard every 3 years, or colonoscopy every 10 years); prostate cancer screening discussion for men (PSA testing with physician discussion of benefits and limitations); skin cancer screening if high-risk (family history, fair skin, high UV exposure).
Ages 50+: Annual mammography for women; colonoscopy every 10 years (or FIT annually); annual low-dose CT lung cancer screening for current/former heavy smokers (55-80 years, 30+ pack-year history); prostate cancer screening for men per physician recommendation; bone density scan for women at 65+ (or earlier with risk factors); annual clinical skin exam; regular oral cancer exam. Key principle: early-stage cancers have 5-year survival rates of 85-95% for most types; late-stage cancers have 15-30%. Screening is not merely reassurance — it is one of the most lifesaving interventions available in modern medicine.
