Breast cancer results from a malfunction of certain cells that multiply, most often forming a mass called a tumor. Cancer cells can remain in the breast or spread to other organs, leading to a more dangerous situation known as metastases. The development of breast cancer typically takes several months or even years.
The chances of recovery depend on several factors, including age, tumor size and type, and the stage of the disease. Generally, the earlier breast cancer is detected, the higher the chances of a cure. It is recommended to consult a healthcare professional for any unusual changes in the breast or under the arm, such as a lump, skin modifications (retraction, redness, swelling), or changes in the nipple or areola.
Key identified risk factors include age (nearly 80% of breast cancers occur after 50), lifestyle choices (alcohol and tobacco consumption, overweight, lack of physical activity), and personal or family history of diseases or cancers, as well as certain medical radiation exposures or hormone replacement therapies.
Screening, particularly through mammography and annual clinical examination, helps detect abnormalities before symptoms appear. Early detection significantly increases survival rates (99% at 5 years) and often leads to less aggressive treatments. Screening is recommended every two years for women aged 50 to 74 and is fully covered by health insurance.
In France, over 2.5 million women undergo screening each year. The town hall encourages participation in this vital cause.
