Cancer screenings are one of the best examples of preventive care actually working as intended: catching potential problems early, when treatment tends to be more effective and less invasive. Medicare covers a solid range of cancer screenings at no cost when you meet the eligibility criteria, but a lot of people don’t take full advantage simply because they don’t know a specific screening is covered — or how often.
Colorectal Cancer Screening
Medicare covers several types of colorectal cancer screening, including colonoscopies, at intervals based on your risk level. For most people at average risk, a screening colonoscopy is covered every 10 years, with more frequent coverage for those at higher risk. Medicare also covers other screening methods, including fecal occult blood tests and stool DNA tests, which can be reasonable options for people who want a less invasive screening approach between colonoscopies. One important detail: if a polyp is found and removed during a screening colonoscopy, the visit is still generally treated as a screening rather than a diagnostic procedure for cost-sharing purposes, though it’s worth confirming this directly with your provider given how billing can vary.
Breast Cancer Screening
Medicare covers annual screening mammograms at no cost for women 40 and older, along with one baseline mammogram for women between 35 and 39. If you have a family history or other risk factors, talk to your doctor about whether more frequent screening or additional imaging makes sense for your situation.
Cervical and Vaginal Cancer Screening
Medicare covers Pap tests and pelvic exams, generally every 24 months, or every 12 months for women at high risk. This screening also typically includes an HPV test at the intervals Medicare specifies, which has become an increasingly important part of cervical cancer prevention.
Lung Cancer Screening
Medicare covers annual low-dose CT lung cancer screening for people who meet specific criteria: generally ages 50 to 80, a significant smoking history, and either currently smoking or having quit within the past 15 years. This is one of the newer additions to Medicare’s preventive screening coverage and remains underused, partly because eligibility criteria are specific enough that not everyone realizes they qualify.
Prostate Cancer Screening
Medicare covers an annual digital rectal exam and PSA (prostate-specific antigen) test for men 50 and older. Unlike some other screenings, there’s ongoing clinical debate about optimal screening frequency and approach for prostate cancer specifically, so this is a good one to discuss directly with your doctor about what makes sense given your individual risk factors.
Skin Cancer Awareness
Medicare doesn’t currently cover routine full-body skin cancer screenings for people without symptoms or risk factors, which surprises some people given how common skin cancer is. If you notice a new or changing mole or lesion, that visit is typically treated as diagnostic rather than preventive, which means normal Part B cost-sharing applies rather than no-cost preventive coverage. It’s still worth bringing up any skin concerns with your doctor promptly, even knowing the cost-sharing difference.
Why “No Cost” Has Real Conditions Attached
Medicare’s preventive screenings are covered at no cost specifically when the visit is billed as a screening and you meet the eligibility criteria for frequency and risk category. If a screening turns diagnostic — for example, additional imaging ordered because something was found — normal Part B cost-sharing can apply to that portion of care. Knowing this distinction ahead of time helps you understand a bill that might otherwise seem inconsistent with what you expected to be a “free” screening.
A Quick Screening Checklist by Age and Risk
- Ask your doctor which screenings you’re currently eligible for based on your age, sex, and personal or family risk factors.
- Confirm the screening interval that applies to your specific risk category.
- If you have a significant smoking history, ask specifically about lung cancer screening eligibility.
- Understand the difference between a screening visit and a diagnostic follow-up for billing purposes.

Bottom Line
Medicare’s cancer screening coverage is broad, but it depends on meeting specific age, risk, and frequency criteria that not everyone is aware of. Talking with your doctor about exactly which screenings you’re eligible for — and how often — is the best way to make sure you’re using this coverage fully.
