The number of cancer diagnoses among people under the age of 50 has increased by approximately 80% globally during the three decades since 1990, and an international research group reported in the journal BMJ Oncology that most of the cases recorded in 2019 were cancer cases. the breast. The fastest increase over the past three decades has been recorded in the number of cases of tracheal and prostate cancer. The number of liver cancer cases recorded in the age group examined decreased by approximately 3%. To conduct the analysis, the team led by Xu Li from the College of Medicine at Zhejiang University in China used the 2019 edition of the “Global Burden of Disease” series of studies issued in Britain. The release contains data collected between 1990 and 2019, on 29 types of cancer in 204 countries, with a focus on people between the ages of 14 and 49 years. According to the data, a total of 3.26 million new cancer diagnoses were recorded in 2019, an increase of 79% compared to 1990.
In total, more than one million people under the age of 50 died from cancer in 2019, an increase of approximately 28% compared to 1990.
Geographically, the highest rates of cancer were observed in North America, Australia and Western Europe, but case numbers were also increasing in low- and middle-income countries, especially among women. The study authors point out the possibility of a lack of inventory or diagnosis data in light of the different quality of cancer registration data in different countries.
