There are 4.57 million people suffering from cancer in China every year! Reminder: these 4 kinds of food, no matter how much you love to eat, keep your mouth shut

As long as people are alive, they can get cancer. "A Brief History of the Human Body" writes: You have 5 chances of getting cancer every day. But most of the time, it's the immune system that saves us.

Do you know what the earliest evidence of human cancer is? It is a fossilized osteosarcoma of the foot bone from 1.7 million years ago. The entanglement between human beings and cancer has a long history. Today, cancer is still an unsolved mystery that haunts mankind.

1. 4.57 million people suffer from cancer every year in China

Cancer is one of the most common causes affecting the health of Chinese residents and leading to death. According to the 2016 China Cancer Data published by the Hejie academician team in JNCC, the total number of new cancer cases in China was 4,064,000 , and the total number of deaths was 2,413,500. For example , between 2000 and 2016, the overall incidence remained stable in men, but increased by an average of 2.3% per year in women.

According to the latest global cancer burden data in 2020 released by the World Health Organization's International Agency for Research on Cancer, there will be 19.29 million new cancer cases worldwide in 2020, of which 4.57 million new cancer cases will be diagnosed in China , accounting for 23.7% of the world's total. The number of new cancer cases and deaths in China ranks first in the world.

At present, the five-year relative survival rate of malignant tumors in China is about 40.5% , which is far behind developed countries. This is caused by the low rate of early diagnosis in China, the small number of early clinical cases, and the non-standard treatment of advanced cases.

2. Why does cancer prefer middle-aged and elderly people?

The incidence and mortality of cancer both increase with age. The Hejie academician team found that the two age groups of 60-64 years and 50-54 years old had the most cancer patients; 60-64 years old and 75-79 years old were the two Men and women in this age group had the most deaths from cancer; the 60-79 age group had the most cancer deaths.

Why does cancer prefer middle-aged and elderly people?

This is because with the increase of age, bodily functions begin to decline, immunity declines, and it is easier to get sick; in addition, the older you are, the more carcinogenic factors you have been exposed to. If carcinogens accumulate to a certain extent, it may induce cancer In addition, the elderly often have a variety of chronic diseases , if they fail to receive regular treatment, cancer may occur.

Therefore, middle-aged and elderly people should be especially alert to the occurrence of cancer. Attention should be paid to these 6 symptoms:

· Unexplained persistent fever: Many cancer patients will have symptoms of fever, especially to be alert to unexplained persistent fever, and to check as soon as possible.

·Nodules and masses appear in the body: These conditions may be benign tumors or malignant tumors. You can identify them from the aspects of size, texture, boundary and activity, and go to the hospital for examination in time.

Inexplicable fatigue and weight loss: In the absence of active weight loss, if you experience weight loss, progressive weight loss, or are accompanied by symptoms such as fatigue, fatigue, and anorexia, you should also be alert to the possibility of cancer.

· Persistent digestive abnormalities: If you have persistent indigestion or are accompanied by upper abdominal pain, acid regurgitation and heartburn, you should be alert to the possibility of esophageal cancer or stomach cancer.

·Changes in bowel habits and traits: such as changes in bowel habits, traits, and frequency, or alternating diarrhea and constipation, you need to be alert to the possibility of colorectal cancer.

Non- traumatic abnormal bleeding : for example, long-term blood in sputum and hemoptysis should be alert to lung cancer; non-menstrual bleeding or irregular vaginal bleeding should be alert to ovarian cancer, endometrial cancer, etc.; painless hematuria should be aware of urinary system tumors and many more.

3. Eat cancer, these 4 kinds of food should be touched less

There are many factors related to the occurrence of cancer, among which eating habits are closely related to the occurrence of cancer, especially these 4 kinds of food should be eaten less.

· Pickled food

Such as bacon, sausage, salted fish, pickled radish, sauerkraut and other pickled foods, most of these foods contain nitrates and nitrites, which are one of the important causes of esophageal cancer.

·Processed meat

Back in 2015, the International Agency for Research on Cancer classified processed meat as a Class I carcinogen. Processed meat mainly refers to meat that can be stored for a long time after being smoked, air-dried, cured, etc., such as ham, bacon, canned meat, hot dogs, bacon, etc. Processed meats often contain large amounts of nitrites, which react with meat proteins to form highly carcinogenic nitroso compounds.

· Moldy food

When the food is moldy, it is easy to produce aflatoxin with strong carcinogenicity. It has been classified as a first-class carcinogen by the International Agency for Research on Cancer, and it is also the strongest carcinogen discovered so far.

· Barbecue and fried food

When food is grilled, it is easy to produce cyclic aromatic hydrocarbons and 3-4 benzopyrene substances with clear carcinogens. Fried foods are prone to produce carcinogenic substances such as malondialdehyde and polychlorinated biphenyls due to the repeated heating of edible oil at high temperatures.

Fourth, after physical examination, these diseases may be precancerous lesions

Physical examination is one of the effective ways to detect early-stage cancer. If these kinds of precancerous lesions are found in the physical examination, you should go to the hospital for further examination in time and pay attention to reexamination.

①Atypical breast hyperplasia → breast cancer

The development of breast cancer is from normal mammary duct hyperplasia → atypical hyperplasia → breast cancer in situ - invasive breast cancer.

② Liver cirrhosis → liver cancer

There are three main steps in the occurrence of liver cancer, hepatitis → liver cirrhosis → liver cancer. This process is a slow evolutionary process.

③Adenomatous intestinal polyps → colorectal cancer

About 95% of colon cancers develop from colon adenomas, and it takes about 5 to 15 years to develop from polyps to cancer.

④ Cervical intraepithelial neoplasia → cervical cancer

If cervical epithelial cells continue to be infected by HPV virus, they may gradually develop from atypical hyperplasia to cervical cancer, which takes an average of more than 10 years.

⑤ Chronic atrophic gastritis → gastric cancer

The occurrence of gastric cancer usually requires multiple processes, from normal gastric mucosa → chronic superficial gastritis → chronic atrophic gastritis → intestinal metaplasia → dysplasia → gastric cancer.

In short, cancer prevention should start from many aspects, develop good living habits, eat less or no food that is easy to cause cancer, and also have regular physical examinations. If precancerous lesions are found, they must be diagnosed and treated in time.
