According to the latest “Panorama of Cancers”, which has just been published by the National Cancer Institute (INCA), the number of new cases of cancer might reach 433,136 cases in 2023, all cancers combined. Or a doubling of the number of cancer cases since the 1990s. Explanations.
Twice as many cancer cases in 2023 as in 1993
Pollution, occupational exposure, ultra-processed food, change in lifestyles, … so many factors regularly singled out for their involvement in the development of many cancers. The figure published by the National Cancer Institute reports a doubling of the number of new annual cases of cancer between 1993 and 2023, i.e. in just thirty years. And the pace seems to be accelerating as the number of new cases is growing faster and faster year following year. According to projections, more than 50,000 new cases of cancer might be identified in 2023 compared to previous years.
For the National Cancer Institute, several parameters can explain this increase:
The ageing of the populationwhich might explain 48% of the increase in male cancer cases and 30% of the increase in female cancer cases; Population increase, leading to higher population densities, particularly in urbanized areas, with an increase in air pollution issues. The increase in population might explain 48% of the increase in male cases and 27% of the increase in female cases; An increased risk of certain cancersin connection with environmental factors.

Some cancers go up, some go down
All cancers do not increase in the same proportions. In men, the cancers that have increased in recent years are:
Among women, the rise in cases is of particular concern for the lung cancer and to a lesser extent for liver and pancreatic cancers.
In view of, and despite the overall increase in cancer cases in both sexes, some cancers are receding over the years, in particular ENT cancers, esophageal cancerthe stomach cancer, le cancer colorectal or lung cancer in men, and in women stomach cancer and certain gynecological cancers (ovary and cervix). The cancer be you remains the most common cancer in women.

Breast cancer in women and prostate cancer in men, the two most common cancers
How can the increase in cancers be limited, or even reverse the trend in the coming years? There cancer prevention and screening are the two main means of fighting cancer. Changing lifestyle habits and behavior (diet, physical activity, sedentary lifestyle, alcohol and tobacco consumption, etc.) is essential for reducing the individual risk of cancer and therefore reducing cases on a national scale. Some cancers, such as cervical cancer and liver cancer can also – at least in part – be prevented by vaccination, respectively by vaccination once morest HPV infections and by vaccination once morest hepatitis B. In addition, organized screening strategies allow early and regular screening of certain cancers (cervix, breast, colorectal, etc.).
Diagnostic and therapeutic progress more often makes it possible to detect cancers at the earliest stages of tumor development, offering a more favorable prognosis for patients. The rise of targeted cancer therapies (hormone therapy, immunotherapy, etc.) contributes to improving the treatment and management of cancers. The cancer with the best prognosis remains prostate cancerthe most common cancer in men, with a 5-year net survival rate of 93%.
