overall situation

The "20 12 Annual Report on Cancer Registration in China" recently released by the National Cancer Registration Center shows that in recent 20 years, tumors in China have shown a trend of younger age, higher morbidity and mortality. There are about 3120,000 new cancer cases every year, and 6 people are diagnosed with cancer every minute. The onset age of breast cancer, lung cancer, colon cancer, thyroid cancer and other cancers all appeared earlier.

Material factor

1.？ environmental factor

With the acceleration of industrialization, environmental pollution is becoming more and more serious, and carcinogens in the environment are also accumulating rapidly, which directly leads to the increase of cancer incidence. Air pollution directly increases the incidence of lung cancer; The pollution of water and soil will lead to the accumulation of carcinogens in food through the pyramid effect of biological food chain, causing malignant tumors in digestive tract; Chemical raw materials contained in decoration materials and cosmetics can directly lead to blood tumors and so on.

2.？ Change one's lifestyle

With the improvement of living standards, people's lifestyles have also undergone significant changes; Bad living habits, eating habits and sexual behavior will all increase the risk of cancer. The westernization of diet directly increases the occurrence of colorectal cancer, and presents an obvious trend of youthfulness. Long-term smoking increases the incidence of lung cancer and laryngeal cancer, and unclean sex leads to a younger incidence of cervical cancer.

3.？ social factor

At present, the fierce social competition, people's fast pace of life and high work pressure often lead to psychological and spiritual problems, which are related to the occurrence of cancer. Psychological research has long confirmed that cancer is a physical and mental disease; Most studies also believe that the occurrence of cancer is related to certain personality characteristics, that is, the so-called "cancer personality". People who are often in a state of tension, anxiety and depression are high-risk groups of cancer. Young people's long-term exposure to this psychological state also stimulates the occurrence of cancer from the side.

In a word, the occurrence of cancer is the result of the joint action of its own factors and environmental factors, and the rejuvenation of cancer is the final product of the joint action of many factors such as environment and society.

What do young people need to pay attention to

? In recent years, it has been found that in recent 20 years, cancer in China has been younger, and young people are easy to become high-risk groups of lymphoma. /kloc-the incidence of gastric cancer in young people aged 0/9 ~ 35 has doubled compared with 30 years ago. Young people are the best time in their lives, but they will get cancer, so let the white-haired people send them to the black-haired people. The trend of cancer rejuvenation means irreparable loss to society and families, as well as to units and individuals. Nowadays, it should be an urgent social problem to prevent cancer from becoming younger.

Young people should first find their own problems, pay attention to diet and rest time, and don't often stay up late to eat some spicy food. This must be corrected. The former sages advocated that if you want to educate his spirit, you must first savage his body. In Gao Shuai, both civil and military skills were once more enviable capital than wealth, which should not be out of date. Physical exercise has always been the best choice for young people to keep fit and keep youthful vitality. While overcoming bad living habits, young people should at least choose a sport that suits them and keep exercising for a long time.

Although cancer is also related to many factors, such as the environment. But just pay attention and exercise more. There won't be any problems
