An international research team led by experts from Zhejiang University in Hangzhou (China) has found that people under 50 are much more likely to develop cancer – 80% of the number of “young” cancer patients in the past 30 years. It is estimated that their numbers will increase by 31% by 2030. The scientists’ work was presented in a published paper magazine BMJ Oncology.
The authors analyzed data from the large Global Burden of Disease (GBD) 2019 study of 29 cancers worldwide. The results showed that the number of cancer cases was 1.8 million in 1990, this number increased to 3.2 million in 2019, with the death toll increasing by 27%.
Researchers note that among the most common types of cancer in women are breast cancer, trachea, lung, stomach and bowel cancer. The sharpest increase in mortality was observed in people with kidney or ovarian cancer.
However, experts were unable to determine the exact cause of the increase in the case. One of the theories put forward by scientists says that malnutrition, alcohol consumption, nicotine addiction, lack of physical activity and obesity may be among the factors that trigger the development of the disease.
