You are due for a checkup and you are not sure what to ask for. Most people are not, because screening advice changes with age and is spread across a dozen sources. This guide pulls the national preventive guidance for women at average risk into one table, then explains how to turn it into your own calendar. It is written for the US; other countries run their own programs with different ages, so check your national health service if you live elsewhere.

The screening table by age

Screenings by age for women at average risk, from US national preventive guidance
ScreeningAgesHow often, in general
Blood pressureFrom 18Every three to five years from 18 to 39 if normal; every year from 40 or if at higher risk.
Cervical screening21 to 65Pap test every three years from 21; from 30, a Pap every three years or an HPV test every five.
HIV and hepatitis CAdultsHIV at least once from 15 to 65; hepatitis C at least once from 18 to 79.
Depression and anxietyAdultsAsked about in routine care; anxiety screening is recommended for adults under 65.
Mammogram40 to 74Every two years for women at average risk.
Diabetes and prediabetes35 to 70For adults with overweight or obesity, with repeat checks if normal.
Cholesterol and heart risk40 to 75A risk assessment that includes cholesterol, to guide prevention.
Colorectal screening45 to 75Several test options with different intervals; discuss which suits you.
Lung cancer50 to 80Yearly low-dose scan for people with a significant smoking history.
Bone density65 and overEarlier for postmenopausal women at higher risk of fracture.

At average risk means no strong family history, no earlier abnormal results and no symptoms. If any of those apply, your clinician may start earlier or check more often. Dental checkups, eye exams and skin checks are also worth keeping on your calendar, on the schedule your dentist, eye doctor or clinician suggests.

In your twenties and thirties

The core is blood pressure, cervical screening and a one-time check for HIV and hepatitis C. It is also the time to start two habits that make every later appointment better: writing down your family health history, and tracking your cycle so you have a record when something changes. Learn breast self-awareness: knowing your normal, so a change stands out.

In your forties

Mammograms start at 40 under current guidance, and a heart and diabetes risk check becomes routine. Perimenopause often begins in this decade; a log of symptoms makes the conversation easier, and what every woman should know about menopause explains what to track. Learn to read your own blood pressure and cholesterol numbers, and learn the heart attack symptoms more common in women.

From 45 and into your fifties and sixties

Colorectal screening starts at 45, lung screening applies at 50 if you have a significant smoking history, and by 65 a bone density scan is recommended, earlier if you are at higher risk. Protecting your bones is a long game; bone health covers the habits that help at any age.

A worked example: turning the table into your calendar

Take a 42 year old at average risk whose last cervical screening was an HPV test three years ago, who has never had a mammogram, and whose blood pressure was checked at a clinic last spring. Reading the table: blood pressure is due yearly from 40, so it is due again this spring; the HPV test is on a five year interval, so it is due in two years; a mammogram is due now, and then every two years; colorectal screening starts at 45, in three years. That gives four dates to write down. On the safety and admin card you can record each one and print it.

How to use this with your clinician

  1. Before the visit, list each screening in the table for your age and the date you last had it. health screenings every woman needs by age walks through it.
  2. Prepare a one-page list with your concern, your medicines and your family history.
  3. Ask which screenings are due, which can wait, and whether your history changes any start date.
  4. Ask how you will receive results. If you feel dismissed, ask what was ruled out and why.

Common mistakes

If low mood or anxiety is part of what you are dealing with, knowing when to talk to a therapist matters as much as any scan. In a crisis in the US, call or text 988.

Frequently asked questions

At what age should women start mammograms?

Current US national preventive guidance recommends a screening mammogram every two years from age 40 to 74 for women at average risk. A family history or other risk factors can change that, so ask your clinician what applies to you.

How often do I need a Pap or HPV test?

Under current US guidance, cervical screening usually starts at 21 with a Pap test every three years, and from 30 to 65 can be a Pap test every three years or an HPV test every five years. Your history can change the interval.

When should colorectal screening start?

Current US guidance recommends colorectal screening from age 45 for adults at average risk, with several test options. A close relative diagnosed young can mean starting earlier.

Can this page tell me if I am healthy?

No. It lists screenings that national guidance recommends by age so you can ask the right questions. It diagnoses nothing. Any symptom needs a visit on its own, whatever your screening dates.
