Cancer screening in Spain: which tests, at what age?

Spain's public health system screens adults for three cancers: breast, colorectal (bowel) and cervical. Women aged 50–69 are invited for a mammogram every 2 years. Men and women aged 50–69 are sent a stool blood test every 2 years. Cervical screening runs from 25 to 65, using a smear or an HPV test depending on age.

This guide explains who is invited, which test is used, how often, and what to do if you are new to Spain, not yet registered, or used to the UK schedule. It is written by Dr. Pedro Yelamo Vera, a GP licensed in Spain.

Why does cancer screening matter in Spain?

Spain expects 301,884 new cancer diagnoses in 2026, according to the Spanish Society of Medical Oncology (SEOM) and the Spanish Network of Cancer Registries (REDECAN). Colorectal cancer is the most common, with 44,132 expected cases, followed by breast cancer with 38,318. Screening finds these cancers, and the polyps that come before bowel cancer, while they are easier to treat.

Which cancers does Spain screen for?

The national programmes cover three cancers where screening saves lives: breast, colorectal and cervical. They are part of the common services of the Spanish National Health System, so every region offers them. Each region runs its own invitations, so letters, phone numbers and test centres vary.

Breast cancer screening: who and how often?

Women aged 50 to 69 are invited for a mammogram every 2 years. Some regions have started to invite women up to 74, and others plan to. The invitation comes by letter or text message from your region's programme, not from your GP.

Bowel (colorectal) cancer screening: who and how often?

Men and women aged 50 to 69 receive a home stool test that looks for hidden blood (test de sangre oculta en heces) every 2 years. You collect a small sample at home and take it to your pharmacy or health centre, as the letter explains. A positive result leads to a colonoscopy (see what a positive stool blood test means). Some regions are extending the upper age to 74.

Cervical cancer screening: who and how often?

• Age 25 to 29: a smear (citología) every 3 years for women without adequate HPV vaccination. Vaccinated women can start at 30.
• Age 30 to 65: a test for high-risk human papillomavirus (HPV) every 5 years, whether or not you are vaccinated.

These rules were updated recently and may change again as more women are vaccinated against HPV.

What about prostate, lung or skin cancer?

Spain has no national population screening for these cancers. A PSA blood test for prostate cancer, or a scan for lung cancer, is a decision you make with a doctor after weighing your personal risk, symptoms and family history. Testing without a reason can lead to false alarms and procedures you did not need.

How do you get invited if you are new to Spain?

Invitations go to people registered with a regional health service. Once you have your health card (tarjeta sanitaria), check with your centro de salud that your address is correct and ask whether you are due. If you are covered privately, your insurer or GP can arrange equivalent tests, but they are not part of the public programme.

How does the Spanish schedule compare with the UK?

The tests are similar but the ages and intervals are not identical. Bring the date and result of your last mammogram, bowel test or smear. Your GP can then tell you when your next Spanish test is due and avoid a gap or an unnecessary repeat.

What does a positive screening result mean?

A positive result is not a diagnosis. It means you need a further test, such as a colonoscopy after a positive stool test or a colposcopy after a positive HPV test. Most people with a positive screening result do not have cancer, but the follow-up test should not be delayed.

When should you see a doctor instead of waiting?

Screening is only for people without symptoms. See a doctor soon if you notice blood in your stool, a change in bowel habit that lasts, a new breast lump, nipple changes, or bleeding between periods or after sex. For an emergency, call 112.

How can an online GP help?

1. Pedro Yelamo Vera can explain a screening letter or result in English or Spanish, tell you what the next step is, and write a referral letter when it is clinically appropriate. Upload the letter through the patient portal and ask by eConsult, or book a video visit. The tests themselves are done in person.
