The brain, kidney, breast or colorectal cancers have seen their impact from 2000 to 2020 in continental France between adolescents and young adults, in whom cancers remain rare than in older people, according to a study published on Monday, March 3.
For the first time, Public Health France, in association with the National Institute of Cancer in particular, publishes data on the incidence of cancers in France between adolescents and young adults aged 15 to 39, according to two decades of departmental figures.
New necessary studies
This emerges an increase in the incidence of six cancers: glioblastomas: aggressive form of brain cancer -(+6.11%on average per year), kidney cancers (+4.51%), liposcomces -tumers hosted in adipose tissues -(+3.68%), hyodgkine limpomas -a of the lymphatic system -(+1.86%) of breast (+1.60%) and colorectal (+1.43%).
“Obesity could be an explanatory factor in the increase in the cancers of the digestive system, including colorectal and renal cancers,” but this remains to be demonstrated, depending on the study. Currently, 9.2% of young people aged 18-24, 13.8% of children aged 25 to 34 and 16.7% of 35-44 years.
For the health agency, new studies are needed to “better understand risk factors and exhibitions caused by the observed increases” and strengthen prevention.
Some cancers in decline
On the other hand, the incidence of certain cancers decreased during the period of 20 years studied: that of melanomas (-3.05% per year), “probably in relation to prevention measures”, as well as that of the cancers of the head and neck (-1.1.24%).
For other tumors, the incidence stabilized “at the end of the period”: testicle cancers, after having increased until 2012, and those in the uterine neck, after a fall until 2013.
However, the incidence of cervical cancer could decrease with a better coverage of papilloma vaccine (HPV), estimate the authors of the study, calling to reach the threshold of 80% of vaccinated adolescents by 2030.
Between 2000 and 2020, 54,735 people aged 15 to 39 had had a diagnosis of cancer in the 19 departments concerned with the study, which represent almost a quarter (24%) of the population of France.
In women, breast cancers and thyroid, as well as melanomas, are the most common in this period. In humans, these are testicles, Hodgkin or Hodgkin lymphomas, melanomas, gastrointestinal and urinary cancers.
Several recent studies report An increase in this disease in young adultsin particular digestive cancers (colon, esophagus, liver …) but also thyroid, breasts and kidneys. BMJ Oncologyand this phenomenon particularly affects developed countries.
