Cancer screening: programs organized in France

IRIS Prévention
2 September 2026
Detecting cancer before symptoms appear often means treating it earlier, more simply and with a better chance of cure. Organized programs exist for this.

In France, three cancers are the subject of organized screening, free and accessible to targeted populations: breast cancer, colorectal cancer and cervical cancer. These programs are based on a simple idea: early detection for better treatment. However, participation often remains below the objectives. Let's take stock.

1. Why screen?

Cancer detected early is generally easier to treat and has a better prognosis. Some screenings even make it possible to identify precancerous lesions and treat them before they develop into cancer, such as for the cervix or colon.

2. The three organized programs

CancerPopulationReview
BreastWomen 50 – 74 yearsMammogram every 2 years
Colorectal50 – 74 yearsImmunological test every 2 years
CervixWomen 25 – 65 yearsSmear then HPV test

These screenings are supported and are the subject of invitations sent automatically, often by mail.

3. Colorectal screening, simple and at home

The colorectal cancer screening test can be done at home in just a few minutes. He looks for invisible traces of blood in the stools, a possible sign of lesions. In the event of a positive test, a colonoscopy is offered to verify. It is a particularly effective and yet underused screening method.

4. Beyond programs

Some people, due to personal or family history, require specific monitoring outside of organized programs. Other cancers (skin, prostate) are not subject to organized screening but may warrant individual monitoring discussed with the doctor.

Taking part in the screenings offered means giving yourself the best chance: the process is simple, free, and can really save lives.

💡 tips to remember

    • France offers three free organized screenings: breast (mammogram), colon (home test) and cervix (smear then HPV test).
    • Cancer detected early is easier to treat and has a better prognosis; some screenings even identify lesions before they become cancerous.
    • The colorectal test can be done at home in a few minutes: simple and effective, yet it remains underused.
    • The invitations are sent automatically according to age: I don't leave them aside and I make an appointment.
    • In the event of a personal or family history, specific follow-up may be necessary outside of the programs: I speak to my doctor.
