Screenings & scans to ask for

These are the tests that catch cancer and vascular problems before they cause symptoms. Missing them is where not having a family doctor hurts most. Use the country switch in the header to tailor guidance.

Colorectal cancer screening

Start at 45. Colonoscopy every 10 years, or FIT stool test yearly.
Cancer screening

Colorectal cancer is one of the most preventable cancers when caught early.

Ask for it like this

"I'm due for colorectal screening. Can you order a FIT test, or refer me for a colonoscopy?"

Early colonoscopy (family history)

Start 10 years before your relative's diagnosis, or age 40
Cancer screening

Family history significantly raises your risk and lowers the recommended start age.

Ask for it like this

"I have a first-degree relative with colon cancer β€” I need a referral for a colonoscopy."

Cervical cancer screening (Pap / HPV)

21–29: Pap every 3 years. 30–65: HPV test every 5 years.
Cancer screening

HPV-driven cervical cancer is almost fully preventable with screening. Testosterone can cause atrophic changes that need a note on the requisition so the lab interprets the sample correctly.

Ask for it like this

"I have a cervix and I'd like a Pap and HPV test. If a speculum exam is uncomfortable, can we discuss self-collected HPV swabs?"

Mammogram / chest imaging

Every 1–2 years from 40–74
Cancer screening

Screening reduces breast cancer deaths from age 40. Trans women on estrogen for 5+ years have similar risk to cis women and are screened the same way.

Ask for it like this

"I'd like a mammogram referral. (Trans women on estrogen 5+ years: same recommendation.)"

Chest wall check after top surgery

Annual clinical chest exam; imaging only for symptoms
Cancer screening

Top surgery removes most, but not all, breast tissue. Cancer risk is low but not zero.

Ask for it like this

"I've had top surgery β€” can you do a clinical chest wall exam and show me how to check the residual tissue myself?"

Early mammogram (family history)

Start 10 years before the relative's diagnosis; discuss MRI too
Cancer screening

BRCA and other genetic risks change the screening timeline substantially, regardless of gender identity.

Ask for it like this

"I have family history of breast/ovarian cancer β€” can I get a genetic-risk referral and early imaging?"

Low-dose CT (lung cancer)

Yearly from 50–80 if 20+ pack-year smoking history
Cancer screening

Catches lung cancer at a curable stage in high-risk smokers.

Ask for it like this

"I have a smoking history β€” I'd like a low-dose CT lung cancer screen."

Skin check

Self-check monthly; clinician check every 1–3 years if fair-skinned or high sun exposure
Cancer screening

Melanoma is highly curable when caught early.

Ask for it like this

"Can you look at any moles that have changed? I don't have a dermatologist."

Anal cancer screening

Discuss yearly if HIV+, MSM, or history of receptive anal sex
Cancer screening

HPV-related anal cancer risk is higher for people living with HIV and for people who have receptive anal sex. Under-screened in most primary care.

Ask for it like this

"Given my history, should I have an anal Pap or high-resolution anoscopy?"

Blood pressure check

At every visit, at least yearly from 18
Heart & vascular

Hypertension is silent and the #1 preventable cause of stroke.

Ask for it like this

"Please check my blood pressure and tell me the numbers so I can track it."

Baseline ECG

Once around 40, or earlier with symptoms/family history
Heart & vascular

A baseline makes it far easier to spot changes later.

Ask for it like this

"Can I get a baseline ECG to keep on file?"

Clot-risk conversation (on estrogen)

At start of therapy and yearly
Heart & vascular

Oral estrogen raises venous clot risk more than transdermal. Worth knowing before surgery or long flights.

Ask for it like this

"I'm on estrogen β€” can we review my clot risk, especially if I smoke, travel long-haul, or need surgery?"

Atrial fibrillation check

Ask about pulse checks / ECG from 65, or sooner with palpitations
Heart & vascular

AFib is a leading cause of stroke and often has no symptoms.

Ask for it like this

"I'd like to be checked for atrial fibrillation β€” pulse check or ECG."

Abdominal aortic aneurysm ultrasound

One-time ultrasound between 65 and 75 if you've ever smoked
Heart & vascular

A ruptured aneurysm is usually fatal; the one-time scan prevents that. Recommended based on smoking history β€” some guidelines extend to anyone assigned male at birth who smoked.

Ask for it like this

"I'd like the one-time AAA ultrasound."
