Can I request a mammogram if I am not yet invited?

Many people wonder whether they can simply ask for a mammogram: before the age their country starts inviting people, or in the years between invitations. The answer depends on where you live, how old you are and, most of all, on whether you have symptoms. This page explains how referral generally works in the United States, England and Canada, the difference between a screening and a diagnostic mammogram, and what you might ask your doctor. It describes systems; it cannot tell you what applies to you.

Screening and diagnostic mammograms are different

A screening mammogram is an x-ray of the breasts done to look for cancer in people who have no symptoms. A diagnostic mammogram is done to check a lump or other change that you or your doctor has found.11National Cancer Institute: Mammograms Opened October 2026; explains screening versus diagnostic mammograms and that diagnostic ones need more angles and a higher dose. The same machines are used, but a diagnostic exam takes more images from more angles, so the radiation dose is higher.

The US National Library of Medicine's MedlinePlus lists the signs that lead to a diagnostic mammogram: a lump, breast pain, thickened skin, nipple discharge or a change in breast size or shape. These signs can also come from a benign (not cancer) condition.22MedlinePlus: Mammography Opened October 2026; describes screening and diagnostic mammograms and when each is used. A diagnostic mammogram may also follow an abnormal screening result, to look more closely at the area of concern.33RadiologyInfo.org: Mammography (Mammogram) Page last reviewed February 4, 2025; defines screening and diagnostic mammography.

In the United States

The National Cancer Institute (NCI) says mammograms are offered at breast clinics, hospital radiology departments, mobile vans, private radiology offices and doctors' offices. It adds that you may be able to schedule a screening mammogram directly with the facility, without a referral from your doctor.11National Cancer Institute: Mammograms Opened October 2026; says direct scheduling of a screening mammogram may be possible without a referral. Rules still vary by facility and insurer, so a phone call to the facility is the quickest check.

Age matters for cost as well as access. NCI states that insurance plans governed by the Affordable Care Act must cover screening mammograms every 1 to 2 years for women 40 and over without copayments, and that a diagnostic mammogram should be checked with your insurer.11National Cancer Institute: Mammograms Opened October 2026; coverage for screening mammograms from age 40 and a note to check diagnostic coverage. The task force that sets much of US practice recommends a mammogram every 2 years from 40 to 74.44US Preventive Services Task Force: Breast Cancer Screening Published April 30, 2024; biennial screening mammography for women 40 to 74. Below 40, guidance usually involves higher risk. The American Cancer Society describes yearly MRI and mammography, typically starting at age 30, for people at high risk, and the decision is made with a doctor.55American Cancer Society: ACS Breast Cancer Screening Guidelines Last revised July 23, 2026; high-risk guidance, typically from age 30.

In England

The NHS sends invitations automatically: a first invitation between ages 50 and 53, then every 3 years. If you have not been invited by 53 and think you should have been, you can contact your local breast screening service. After 71 you are no longer invited automatically, but you can call the service to ask for an appointment every 3 years.66NHS: Who breast screening is for Page last reviewed 9 October 2025; invitation ages and how to contact the service.

Under 50, routine screening is not offered. Cancer Research UK says the best evidence suggests the harms outweigh the benefits at that age, and that people with a higher risk from family history or an inherited gene change can have screening from a younger age. The route is to speak to a GP, who can refer you to a genetic specialist or a specialist breast clinic for assessment.77Cancer Research UK: Breast screening (mammography) Last reviewed 21 May 2026; under 50 and higher-risk routes to screening.

In Canada

Canadian screening programs are run by provinces and territories. The Canadian Cancer Society notes that not every province or territory offers mammograms through an organized program, or by self-referral, to people in their 40s.88Canadian Cancer Society: Screening for breast cancer Last medical review April 2024; availability for people in their 40s differs by province or territory. The Canadian Task Force's draft recommendations say programs should give clear information however people reach screening, whether by self-referral, invitation or a health care provider.99Canadian Task Force on Preventive Health Care: Breast Cancer (Update), Draft Recommendations (2024) Archived draft; the guidance for programs names self-referral, invitation and provider referral. For ages and intervals by country, see what age to start, and stop, by guideline.

The NHS advises seeing a GP as soon as possible about symptoms, even soon after a screening mammogram.1010NHS England: Your guide to NHS breast screening Crown copyright 2026; urges contacting a GP about symptoms between screening appointments. The American Cancer Society likewise says people should report any change to a health care provider right away.55American Cancer Society: ACS Breast Cancer Screening Guidelines Last revised July 23, 2026; says to report breast changes right away.

What to ask your doctor

Before booking, a few questions can save time. RadiologyInfo advises bringing earlier mammograms if they were done elsewhere, so the radiologist can compare them.33RadiologyInfo.org: Mammography (Mammogram) Page last reviewed February 4, 2025; advises obtaining prior mammograms for comparison.

• Would this be a screening or a diagnostic mammogram, and why?
• Do I need a referral, or can I book directly?
• What do my age and family history mean for when screening begins?
• What will it cost, and what will my plan or health system cover?
• How and when will I get the result, and who do I call if I do not?

For cost questions see costs and access to screening, and for the day itself see preparing for a screening appointment. If family history is the reason you are asking, higher risk: family history, genes and other factors outlines how doctors think about it. Your own doctor or screening service has the final word.
