7.5 people in China are diagnosed with cancer every minute! What do you know about this healthy killer?

February 4th is World Cancer Day.
from WHO shows that one in five people in the world will now develop cancer through their lifetime.
, 7.5 people are diagnosed with cancer every minute in China, according to domestic data.
do you know about this "killer" that is a serious threat to life and health? The latest WHO figures from WHO show that 10 million people will die from cancer worldwide by 2020, with 19.3 million confirmed cancer cases worldwide by 2020, while the number of cancer deaths will rise to 10 million.
cancer is the second-largest cause of death.
now, one in five people in the world will develop cancer in their lifetime, and one in eight men and one in eleven women will die of cancer.
breast cancer is now the most common cancer in the world, accounting for 11.7 per cent of new cancer cases, followed by lung cancer (11.4 per cent), colorectal cancer (10.0 per cent) and prostate cancer (7.3 per cent), with cervical cancer being the fourth most common cancer in women.
, cancer is the leading cause of death among children and adolescents, with about 400,000 children diagnosed each year.
, the incidence of cancer is also worthy of attention.
According to the 2019 National Cancer Statistics released by the National Cancer Center, there are about 3.929 million malignant tumors in China each year, with about 2.338 million deaths and 7.5 people diagnosed with cancer every minute.
The Report on Nutrition and Chronic Diseases in China (2020), released in December 2020, shows that in 2019, the premature mortality rate of Chinese residents due to four major chronic diseases, namely cardiovascular disease, cancer, chronic respiratory diseases and diabetes, was 16.5%, i.e. the probability of each person dying from four major chronic diseases between the ages of 30 and 70 was 16.5%.
incidence of cancer among urban residents was 293.9 per 100,000, which is still on the rise, with lung cancer and breast cancer ranking first among men and women respectively.
the top five cancer deaths were lung cancer, liver cancer, stomach cancer, esophageal cancer, and colorectal cancer.
is this causing the incidence of cancer to rise? What causes the increase in cancer incidence among Chinese residents? On this issue, the Chinese Academy of Sciences, the director of the National Cancer Center He Jie has analyzed that in recent years, with the Chinese mouth aging, industrialization, urbanization process gradually accelerated, coupled with chronic infections, unhealthy lifestyle, environmental exposure and other reasons, so that the incidence of cancer in China is still on the rise.
, according to him, China's cancer spectrum is in the developing countries to developed countries cancer spectrum transition stage.
High incidence of lung cancer, colorectal cancer, breast cancer and so on is rising in developing countries, such as esophageal cancer, stomach cancer, liver cancer and so on compared with the 1970s and 1980s, but the overall burden is still heavy, the overall cancer prevention and control situation is still relatively serious.
In terms of cancer survival rates, China's five-year survival rate has risen from 30.9% to 40.5% in the past decade, an increase of nearly 10 percentage points, but there are still some gaps with the five-year survival rate in developed countries.
The main reasons for these gaps are two aspects, on the one hand, because the first few malignant tumors of cancer in China are mostly poor prognosis, 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 examination 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.
you need to know about cancer! Cancer is a major health threat, so what are the factors associated with the development of such diseases? How can it be effectively prevented? Recently, the reporter interviewed Wang Yingxuan, deputy director of oncology department of Beijing Concord Hospital, on related issues.
- what is the link between cancer and genes? Nearly 30 hereditary cancer syndromes have been identified, and many studies have shown a genetic correlation between cancer.
common malignancies, colorectal cancer has the highest genetic-related rate, up to 20-30%.
, however, inherited genes have no obvious relationship with cancer, and the after-effects play an important role in cancer.
- what are the controllable factors that cause cancer? Earlier, the National Cancer Center analyzed 23 carcinogenic risk factors associated with common cancers in China.
These factors are divided into dietary factors (inadequate intake: fruits, vegetables, dietary fiber, calcium; excessive intake: red meat, processed meat products, pickles), behavioral factors (smoking, secondhand smoke, alcohol consumption, lack of exercise), metabolic factors (overweight, diabetes), environmental factors (PM 2.5 pollution, ultraviolet radiation), infection factors (Helicobacter pylene (HP), hepatitis B virus (HBV), hepatitis C virus (HCV), HIV (HIV), EB virus (EBV), human papillomavirus (HPV), Chinese testicular sucker, human herpes virus type 8 (HHV - 8).
- cancer has a "son-in-law" trend in the face of cancer, gender inequality, cancer has a "son-in-law" trend.
, with the exception of male and female cancers (male and female-only cancers), male cancers have higher morbidity and mortality rates than female cancers.
men with high incidence of cancer are lung cancer, stomach cancer, liver cancer, esophageal cancer, colorectal cancer, bladder cancer, prostate cancer, lymphoma, brain nervous system, pancreatic cancer.
women with high incidence of cancer are breast cancer, lung cancer, colorectal cancer, thyroid cancer, cervical cancer, liver cancer, esophageal cancer, uterine cancer, ovarian cancer.
- What are tumor markers? Tumor markers, tumor markers, tumor indicators refer to the same thing.
In fact, normal cells and cancer cells in the human body produce tumor markers, which are essentially sugars, lipids, peptides, hormones and other substances, but cancer cells produce much more than other cells.
over time, people's understanding of tumor markers has become more and more perfect, and some tumor-related genes have been added to the list of tumor markers.
- Tumor Marker Abnormality - Cancer? Increased tumor indicators are usually not caused by cancer, and the most common cause is non-tumor factors such as inflammation or injury.
for example, hepatitis can lead to elevated AFP associated with liver cancer, CA125 associated with menstrual or ovulation ovarian cancer in healthy women, and elevated levels of cancer embryo antigen CEA in smokers.
the incidence of tumors also confirms this view, the total incidence of all cancers is only a few thousandths, far below the incidence of tumor indicators, a considerable number of people with abnormal signs do not have cancer.
in fact, the root of tumor markers is cell damage, cells including tumor markers and other proteins into the blood, and then with the blood test was detected.
, abnormal tumor indicators do not amount to cancer.
addition, some tumors are metastasis in a comprehensive way and the tumor indicator is never even high, which may be related to the tumor cell not secreting the associated protein or, although secreted but not bleeding.
- is there a "harbinger" before cancer? In fact, cancer doesn't happen all at once, it's a slow process.
, for example, there is a general process of the development of stomach cancer: normal gastric mucosa →hyso chronic superficial gastritis→ chronic atrophic gastritis→ enteric, heterogenous growth→ stomach cancer.
chronic atrophic gastritis can be diagnosed through gastroscopy and mucosal biopsies, as long as the chronic period of timely formal treatment, usually not cancerous.
, for example, more than 95% of colon cancer comes from colon adenomas, which typically take an average of 5 to 15 years from pneumocarcinoma to cancer.
at this stage, the occurrence of bowel cancer can be greatly reduced by a colonoscopy.
there is a trilogy of liver cancer in China: hepatitis→ cirrhosis → liver cancer.
if there is a history of hepatitis B disease accompanied by cirrhosis of the liver, is a high-risk group of liver cancer, if accompanied by imaging found suspicious pretation or elevated fetal protein, it may be cancerous.
, before every cancer occurs, there is actually an early warning, just look at you do not pay attention to!
