[Breast cancer epidemiology].

The breast is the leading cancer site in women throughout the world. That said, breast cancer incidence varies widely, ranging from 27/100,000 (Central-East Asia and Africa) to 85-94/100,000 (Australia, North America and Western Europe). Its frequency in France is among the highest in Europe.

Short- and long-term impact of adapted physical activity and diet counseling during adjuvant breast cancer therapy: the "APAD1" randomized controlled trial.

Background: Patients with breast cancer undergoing chemotherapy and radiotherapy experience fatigue and other treatment side effects. Integrative therapies combining physical activity and dietary counseling are recommended; however to date no large randomized controlled trial has been conducted during adjuvant therapy. The Adapted Physical Activity and Diet (APAD) intervention was evaluated for its ability to decrease fatigue (primary outcome), anxiety, depression, body mass index (BMI), and fat mass, and enhance muscular and cognitive performances, and quality-of-life (QoL).

[Profile of first year secondary school children involved in the anti-smoking prevention trial "PEPITES"].

Background: Many programs which aim to reduce tobacco consumption in young people are carried out in the school environment, addressing a "captive audience" and monitoring the actions over a period of several years. The approaches identified as promising involve putting in place a tobacco prevention program throughout the entire school years incorporated in the school program. Several studies showed that early initiation to psychoactive substances is a strong predictor of addiction.

Rationale, design and conduct of a school-based anti-smoking intervention: the "PEPITES" cluster randomized trial.

Background: In France smoking initiation rates amongst 11 to 16 year-olds are worryingly high. Several studies show that early initiation to psycho-active substances is a strong predictor of tobacco addiction. Decreasing the age at which tobacco use starts represents a key challenge for reducing tobacco usage.

Low participation in organized colorectal cancer screening in France: underlying ethical issues.

International studies have shown a significant reduction in colorectal cancer (CRC) mortality following the implementation of organized screening programs, given a sufficient participation rate and adequate follow-up. The French national CRC screening program has been generalized since 2008 and targets 18 million men and women aged 50-74 years. Despite broad recommendations, the participation rate remains low (29.
