Early detection

Early detection of breast cancer

Early detection of breast cancer means discovering it as early as possible to detect – ideally before symptoms appear.

Early detection does not prevent breast cancer. However, it can detect it at an early stage.

The Mammography is the the most important screening test for early detection. It can make changes in breast tissue visible before a tumour becomes palpable.

Studies show that regular participation in organised mammography screening programmes reduces breast cancer mortality.

Why early detection is important

Appointment confirmed — calendar with a tick

Recommendation

Women aged 50 and over are advised to have a mammogram every two years – if possible, as part of a quality-assured screening programme.

MAMMOGRAPHY

Mammography is the most important examination for the early detection of breast cancer.

Mammography is a special X-ray examination of the breast that can make even the smallest changes visible – including those that are not yet palpable. The examination only takes a few minutes and is carried out in radiology clinics or hospitals.

Better chances of recovery

If breast cancer is detected at an early stage, this significantly improves the chances of recovery.

A gentler approach

In many cases, treatment can be carried out in a gentler manner.

Fewer women are dying

Participation in the mammography screening programme reduces the risk of mortality by 20 - 30 percent.

SCREENING PROGRAMME

In many cantons, women aged 50 and over are invited to take part in quality-assured mammography screening programmes.

In Switzerland, cantons decide on the introduction of a mammography screening programme.

from 0

These programmes attract women from age 50 for a mammogram every two years. Franchise-exempt and voluntary.

Currently Eight cantons have no mammography screening programme.

NEW STUDY

Breast cancer screening significantly reduces mortality
Women who regularly participate in a mammography screening programme have a 20 to 30 percent a lower risk of dying from breast cancer than women who do not participate in screening. This is shown by the latest data from a large-scale study from Germany, carried out by Federal Office for Radiation Protection. The study is based on data from up to ten million women in the period from 2009 to 2018.

In cantons with a mammography screening programme, breast cancer is detected significantly more often in earlier stages – with smaller tumours and less frequent lymph node involvement.
