Recently, several young patients were treated, such as 18-year-old peripheral primitive neuroectodermal tumor, 19-year-old lung cancer, 26-year-old gastric cancer, and 31-year-old rectal cancer, etc. All of these patients were advanced and had a very poor prognosis. In addition, most of these patients were physically unwell and failed to seek timely medical attention. Let’s look at the official release again. The 2012 China Tumor Registry Annual Report released by the National Tumor Registry recently shows that cancer in China has shown a trend of youthfulness, high incidence and mortality in the past 20 years, with about 3.12 million new tumor cases each year, and 6 people are diagnosed with cancer every minute. The age of onset of cancers such as breast cancer, lung cancer, colon cancer and thyroid cancer are all appearing earlier. The trend of younger cancer and higher incidence and mortality rates means irreparable losses for society and families, for organizations and individuals. Families of patients almost always ask their doctors why they got tumors? There is a consensus among colleagues in the oncology field: various kinds of pollution are the culprits, among which environmental pollution is the most scourge. Some doctors even lament that our next generation will be lucky to live to 60 years old! The diseases caused by environmental pollution in human body may be more terrible than infectious diseases such as hepatitis and AIDS! Reducing environmental pollution and pollution exposure will definitely reduce tumor occurrence! Reducing all possible pollution can reduce cancer incidence and mortality rate. To reduce environmental pollution, we must control the source! Young people, who need to pay attention to early diagnosis of tumors, need to protect themselves more and reduce pollution exposure to prevent tumors from occurring.
