What can we learn from the dramatic decline in cancer deaths in the United States in 2021?

According to the latest Global Cancer Burden Data 2020 released by the World Health Organization's International Agency for Research on Cancer (IARC), there will be 19.29 million new cancer cases worldwide in 2020, including 4.57 million new cancers in China, accounting for 23.7% of the world's total. Death toll exceeds 3 million, see: 2020 latest global cancer data: Breast cancer replaces lung cancer as the world's largest cancer, China's annual cancer death toll exceeds 3 million U.S. cancer five-year survival rate of up to 67% (see: U.S. Cancer Statistics 2021) 1.89 million new cases, 600,000 deaths, the second year in a row that the mortality rate has dropped significantly), according to the latest Report on Nutrition and Chronic Diseases in China (2020), China's five-year cancer survival rate is 40.5%, a significant gap from that of the United States.
According to the Director of the National Cancer Center, he jie academician, China's cancer five-year survival rate compared with developed countries, the main reason is that, on the one hand, China's cancer incidence of the first few malignant tumors are mostly poor prognosis, such as lung cancer, esophageal cancer, stomach cancer, liver cancer and so on.
On the other hand, China's cancer screening and early diagnosis and treatment coverage of the population is relatively small, the public active participation in anti-cancer screening awareness is not strong enough, most patients in the discovery of cancer is already in the middle and late stage, so the treatment effect is relatively poor.
addition, the level of clinical standardization and homogenization needs to be further improved.
the overall growth trend of lung cancer morbidity and mortality worldwide, the 2021 U.S. Cancer Statistics Report shows that the mortality rate has dropped significantly for 2 consecutive years! Why can the United States reduce the death rate of several major cancers, including lung cancer, year by year, and what can we learn about cancer prevention? First, cancer screening cancer early screening technology to improve and promote, so that more cancer patients in the early detection of timely intervention and treatment, improve the overall five-year survival rate.
1, prostate cancer --- 5-year survival rate of about 99%! 2, thyroid ---- 5-year survival rate of about 98%! (Depending on the type of tissue) 3, testicular --- survival rate of about 95.1%! 4, melanoma --- 5-year survival rate of about 91.7%! 5, early ---- early stage (0 and 1 stage) 5-year survival rate: 99%-100%! 1, 15 years in advance of the physical examination, it is recommended that over 35 years of age should be regularly checked each year with a family history of cancer, in addition to the general medical examination, must be 15 to 20 years earlier than the age of cancer of immediate family members to go to the cancer specialist hospital or department to do cancer prevention examination.
, for example, if an immediate family member is diagnosed with cancer at age 55, you should start an anti-cancer check-up when you are 35 to 40 years old.
hpV) tests can detect cervical cancer at an early stage.
in many high-income countries, mammogram screening (target) reduces breast cancer mortality.
of colorectal cancer in clinical trials was reduced by screening for fecal latent blood tests.
low-dose spiral CT scans can reduce lung cancer mortality and mortality.
regular gastroenteroscopy can reduce mortality from stomach and colorectal cancer.
2, 40 years of age and older to pay attention to people over 40 years of age, the risk of cancer significantly increased, the need to pay more attention to regular cancer screening.
, strict control of the main risk factors 1, smoking ban in the United States each year due to cancer deaths, lung cancer accounted for more than a <2>.
The tobacco control campaign that began in the 1960s has seen a 40-year decline in the number of smokers, and a total ban on smoking in public places has been followed by strict legal restrictions on the time and place of smoking, from 42.4 per cent to 16.8 per cent for adults, 45 per cent for men and 19 per cent for women.
decline in smoking directly reduces morbidity and mortality from tobacco-related cancers, including lung, throat and bladder cancers, as well as overall morbidity and mortality.
2, weight control was associated with an increased risk of at least 13 types of cancer, including colorectal cancer, post menophageal breast cancer and advanced prostate cancer.
study found that overweight was associated with poor survival in patients with breast, prostate and colorectal cancers.
weight gain can lead to about 8% of cancer cases and 7% of cancer deaths.
report: Mendelsostize says obesity-related cancer risk is underestimated! 3. Increased exercise estimates that 3% of all new cancer cases in the United States (46,300 in 2014) can be attributed to physical ins exercise.
exercise can reduce the risk of colorectal cancer, breast cancer and endometrial cancer.
physical activity can improve the health-related quality of life of cancer survivors.
