Most adults assume their primary care doctor will track their screening schedule for them. Sometimes that works. Often it doesn't, especially for screenings that fall outside the primary care visit itself (dermatology, gynecology, GI, urology, eye). Screening cadences also change over time as guidelines update; the colonoscopy you remembered as starting at 50 was lowered to 45 by the US Preventive Services Task Force a few years ago. Following the recommendation set from your parents' era is no longer accurate.
The list below is a practical decade-by-decade reminder set for adults at average risk. It isn't medical advice; it's a starting point to discuss with your primary care doctor, and a structure for the reminders that follow whatever cadence the conversation lands on. Family history, prior conditions, and personal risk factors can shift many of these earlier or change their frequency.
In your 40s
The 40s are when the screening schedule starts shifting from minimal to substantial. The biggest changes are colorectal and breast cancer screening.
- Colorectal cancer screening, starting at 45. The US Preventive Services Task Force expanded the recommended ages to 45 to 75. Options include colonoscopy (typically every 10 years if normal), stool-based tests (annually for FIT, every 3 years for FIT-DNA), and CT colonography. Set a reminder at 44.5 to schedule the first one.
- Mammogram (starting at 40 or 45). The USPSTF recommends biennial mammography for women 40 to 49; the American Cancer Society suggests annual mammograms 45 to 54, with optional starting at 40. Discuss with your provider which pattern fits.
- Skin check (annually if light-skinned or significant sun history). Dermatology doesn't usually call you. A standing annual reminder catches the visit.
- Lipid panel and blood pressure (every 4-6 years at minimum). Cardiovascular risk starts mattering more after 40. The cadence often becomes annual if any markers are abnormal.
- Diabetes screening (every 3 years starting at 35). Per USPSTF guidance for adults 35 to 70 with overweight or obesity; risk-based earlier.
- Eye exam (every 2 years for adults without conditions). Annual if diabetic or with glaucoma family history.
- Dental cleaning (every 6 months). Easy to forget once you're not getting school-style routine reminders. A standing recurring reminder catches the drift.
In your 50s
The 50s add a few items and intensify the cadence on the ones already running. The biggest additions are prostate cancer discussions, shingles vaccine, and tighter cardiovascular monitoring.
- Continue colorectal, mammogram, lipid, and BP screening on the cadences set up in your 40s. If your last colonoscopy at 45 was normal, the next is typically 10 years out.
- Prostate cancer screening discussion (50, or 45 for higher risk). USPSTF recommends an individual discussion between patient and provider for men 55 to 69. African American men and those with family history often start the discussion earlier.
- Shingles vaccine (50+). Two doses of Shingrix recommended for adults 50 and older.
- Hepatitis C screening (one-time for all adults 18 to 79). Easy to forget; many adults never get this baseline.
- Lung cancer screening (50-80 with smoking history). Annual low-dose CT for adults 50-80 who have a 20 pack-year smoking history and currently smoke or quit within the past 15 years.
- Hearing screening (consider). Not formally a recommended screening for asymptomatic adults but a useful baseline check.
In your 60s
The 60s add bone density screening, AAA screening for men with smoking history, Medicare timing, and several immunizations.
- Bone density (DEXA) screening at 65 for women. Per the CDC, screening is recommended at 65 for women, and for women 50-64 with specific risk factors. Typical follow-up is every 2 years if osteopenia is present.
- AAA (abdominal aortic aneurysm) screening once between 65 and 75 for men who have ever smoked. One-time ultrasound screening per USPSTF.
- Continue colorectal, mammogram, cardiovascular, diabetes screening per the cadences set up earlier.
- Pneumococcal vaccine (at 65). Series usually includes PCV15 or PCV20.
- Medicare Initial Enrollment Period (3 months before to 3 months after 65th birthday). Not strictly a screening but a hard-deadline admin item worth a long-horizon reminder. See the retirement transition checklist for more.
- Tdap booster every 10 years. Easy to lose track of, especially if the last one was decades ago.
In your 70s and beyond
Screening recommendations in the 70s and beyond become more individualized; some screenings continue at the same cadence, others are scaled back, and several stop entirely. The cutoffs depend significantly on overall health and life expectancy, which is a conversation to have with your primary care doctor rather than a generic schedule.
- Colorectal screening continues to 75 routinely, with the decision to screen 76-85 being individualized.
- Mammography continues to 74 per USPSTF; ACS recommends as long as life expectancy is 10+ years.
- Bone density follow-ups continue per prior schedule.
- Annual physical and cognitive check-in become more important as a catch-all for changes that may need follow-up.
- Fall risk assessment becomes a routine item in the 75+ range and isn't always raised by physicians without prompting.
- Several screenings reasonably stop if life expectancy is short enough that intervention wouldn't change outcomes. This is a frank conversation with your provider, not a default.
Setting up the actual reminders
The total list above is longer than most adults realize, but the long-horizon structure makes it easy to manage. Most items recur on multi-year cycles. Set up reminders once, in roughly an evening, and the entire screening schedule runs itself for the next decade.
- For each screening currently due: set a reminder 30 days before the target month, naming the screening and the action ("Schedule mammogram for October").
- For each multi-year cycle: set a reminder 30 days before the next one is due. Mammogram at year+1 or year+2; colonoscopy at year+10; bone density at year+2; AAA at the appropriate age window.
- For one-time items: set a single reminder at the appropriate age (Shingrix at 50, hepatitis C any time, AAA screening between 65 and 75).
- Annual catch-all: set a yearly reminder a month before your annual physical to confirm all screenings are on schedule. The annual physical itself becomes the moment to review and update the list with your doctor.
Why email-based reminders fit screenings well
Medical screening reminders share the same property as other once-per-decade tasks: they need to fire reliably across long horizons, and the system has to survive whatever phone, app, or device you're using when the reminder eventually arrives. Email is the only digital channel most adults keep for ten or more years continuously, which makes it the natural home for reminders that span decades.
BoldRemind handles this without ceremony. You enter each screening's date and cadence, the email arrives on schedule, and the reminder follows up if you don't mark it done. There's no app to maintain in the meantime, no account to forget the password for. The reminders set today for your next colonoscopy in 2036 will still arrive on schedule, in the inbox you'll almost certainly still be using.
The takeaway: medical screening cadences update by decade. Following the current recommendations (not the ones from your parents' era) is what keeps the schedule useful. A practical reminder system, set up once for all the recurring screenings at your age, runs quietly in the background for years and catches the items that nobody else is going to remind you about.
