GLOBOCAN 2018 (a project of the International Agency for Research on Cancer) was officially announced at the end of September. It is estimated that in 2018, the world had 18.1 million cases and 9.6 million deaths from cancer. The number of people globally alive 5 years after detection is 43.8 million

It is often difficult to know exactly why one person has cancer and another does not. Many studies have shown that there are many cancer risk factors such as exposure to chemicals, as well as certain health risk behaviors. Therefore, a correct understanding of cancer risk is very important for cancer prevention.
