A 94-year-old academician who has been studying cancer for more than 60 years has come up with six "cancer prevention prescriptions" that are worth reading

Xiaojiu recently received a sad private message in the background:

This morning my best friend, Lao Liu, died of lung cancer at the age of 68. The company's main business is to provide a wide range of products and services to its customers. As a result, it didn't take long to feel special pain in the chest and had to go to the hospital for examination, which confirmed the diagnosis of advanced lung cancer, which had already metastasized to the bone, and after six months of treatment, it still didn't stay with him.

Suddenly I found that after I got older, my close friends around me were leaving one by one, and the people I could meet to have dinner and chat and travel together were gradually disappearing. I've sent three of them away this year, all because of cancer. Why do you think cancer likes us old people so much? I'm sure I'll leave this world one day because of cancer, too.

I. Why are older people more likely to get cancer?

It's true that the occurrence of cancer has a lot to do with age, and the older you are, the more likely you are to get cancer. Some data show that if you are within 30 years of age, the annual probability of developing cancer is about 0.06%; if you are 70 years old, the risk of developing the disease is more than 100 times that of a 20-year-old. Why are people more likely to get cancer as they get older?

There are three reasons, according to Jiang Yongsheng, chief physician of the Department of Oncology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, China:

First, it has to do with the etiology of tumors and their biological characteristics. It takes 10-30 years for tumors to form. The body is constantly exposed to chronic stimuli and carcinogens, and the risk of cancer increases with age.

Second is the duration of exposure to carcinogens. About 80% of cancer triggers come from external cancer-causing factors, most of which are chemical carcinogens. Some people need to be exposed to harmful substances for a long time because of their work, which also increases the risk of cancer.

Lastly, it is related to immunity. As we age, the body's organs and immune function gradually decline, and the immune system's ability to monitor cancer cells decreases, making it easy for tumors to develop in the body.

5 abnormalities or signals of cancer, do not think it is a chronic disease

In daily life, we should pay more attention to the performance of the body, once found abnormalities should be timely medical treatment, especially these symptoms, need to be highly alert.

1. Unexplained weight loss

Clinical data show that 25% of unexplained weight loss is associated with cancer and is more likely to occur in patients with advanced cancer. Cancer cells continue to compete with normal cells for nutrients in the body, preventing the body from absorbing sufficient nutrients, which then causes the body to lose weight.

2. Unexplained lumps on the body surface

Under normal circumstances, our skin surface should be smooth and free of swelling. Once we find inexplicable lumps on the skin, such as in the breast, neck, armpit and groin, we should be highly alert. In particular, some lumps that are poorly mobile, hard, and develop rapidly in a short period of time are mostly caused by malignant tumors.

3. Blood in the stool

Blood in the stool is mostly associated with gastrointestinal tumors. Bright red color may be associated with sigmoid colon and rectal bleeding; dark red and brown color may be associated with small intestine and right hemicolectomy bleeding; and gastrointestinal bleeding will be very dark in color, and coffee grounds in general.

4. Unexplained pain

Abnormal pain in various parts of the body may be due to primary tumor or tumor metastasis leading to compression, and generally tumor-induced pain lasts longer and is more profound.

5. Persistent cough

Cough is directly related to conditions such as cold, but if there is a persistent cough on the body that cannot be relieved for a long time, you should be alert to the possibility that it is caused by lung cancer.

Three, how to prevent cancer?

The Chinese Academy of Engineering member Sun Yan, who is now 94 years old, is still in good health and active in the public eye. In an interview with the media, he generously shared his "secret recipe" for cancer prevention.

Stay away from carcinogens

Stay away from factors that can trigger cancer, such as moldy foods, smoking, drinking alcohol, and excessive intake of high-calorie foods.

Regular medical checkups

Regular medical checkups can help detect abnormalities in the body in a timely manner, and people of all occupations need to have regular medical checkups. Middle-aged and elderly people, in particular, should add cancer screening to their basic physical exams.

Eat seven percent of your meal

Sun Yan has been very restrained in her diet, keeping her meals only seven percent full for a long time and leaving the table as soon as she feels she has eaten almost enough to avoid overconsumption of food that she cannot control.

Like controlling drunk driving, go for tobacco control

Many tumors are induced by poor lifestyle habits, such as lung cancer. There is a direct relationship between tobacco intake and the development of lung cancer, and some non-smokers can be linked to secondhand smoke. If we can control the smoking ban with the same intensity as we control drunk driving, we believe we will get better results.

Living a regular life

A regular life and adequate sleep are important for the protection of the body's internal environment. Long-term lack of sleep and staying up late can reduce immune function, and digestion, mental activity, cardiovascular and endocrine function can be affected to varying degrees.

No anger, no tossing and turning

Emotional factors are also important for health. Being under long-term stress, anxiety and other adverse emotions can put the body under stress, which in turn can lower the immune system and give cancer cells an opportunity to take advantage of it.

Although the level of medical treatment for cancer has improved greatly compared to the past, we humans are still on the downside. The treatment of cancer also relies on early prevention, early detection, early diagnosis and early treatment. In addition to regular medical checkups, we need to pay attention to whether our body has any abnormalities on a daily basis and seek medical attention in time if we find any abnormalities, and then we also need to adhere to a healthy lifestyle, stay away from carcinogens, regular work and rest, etc.
