In most countries of the world, there is an increase in the number of cases of certain types of cancer. In particular, among people under the age of 50, the rate of growth is leading colorectal cancer.

In a significant part of cases, this trend is associated with obesity, says the study, the results of which published in the scientific journal Annals of Internal Medicine, writes Euronews.

In their work, scientists analyzed statistics on 13 types of cancer in 42 countries on five continents during 2003-2017. The analysis confirmed that some cancers are indeed becoming more common among adults aged 20-49.

In particular, the increase in the incidence of thyroid cancer and mammary glandcolorectal cancer, kidney cancer, endometrial cancer and leukemia were recorded in the vast majority of the studied countries.

The number of thyroid cancer cases grew the fastest – the average annual increase was 3.57%. Next in the ranking are kidney cancer (2.21%) and endometrial cancer (1.66%).

Colorectal cancer grew somewhat more slowly – an average of 1.45% per year. It is noted that unlike most other types of cancer, where rates have increased in both young and older people, colorectal cancer has been an exception to this general trend.

In almost 70% of countries, the rate of increase in new cancer diagnoses was higher among younger people compared to older age groups.

The authors of the study suggest that this may indicate shared risk factors that belong to them adipositychanges in diet and use antibiotics.

At the same time, scientists warn that prevention should not be aimed only at young people, because the vast majority of cancer cases still occur in the older generation.
