Uncle Li would go to the park every day to play a few games of chess leisurely, and his life was enjoyable.
But a sudden phone call shattered his peaceful life.
On the other end of the phone, the hospital informed him that his old friend Lao Wang had unfortunately passed away due to cancer.
Uncle Li was stunned, he and Lao Wang have known each other for many years, and their living habits are similar, they don't smoke or drink, why did Lao Wang leave like this?
After hanging up the phone, Uncle Li's mood couldn't calm down for a long time.
He couldn't help but wonder, "Does everyone have cancer, why do some people get cancer and some people are spared?" This accident made him deeply worried about his health.
He began to reflect on whether he should also pay more attention to the condition of his body.
Actually, Uncle Li's doubts are not superfluous. Cancer, a term that makes people smell and change, is indeed not far away from us.
According to statistics, millions of people in mainland China are diagnosed with cancer every year, and this number is rising year by year.
So, how can you prevent cancer from happening in your life?
01
In this day and age, cancer seems to have become a common disease. Whether it's our friends, loved ones, or news reports, we hear about cancer all over the place.
According to statistics, millions of people on the mainland are diagnosed with cancer every year, including young people and children. This data is staggering, and it also makes us have to face up to the prevalence of cancer.
However, studies have found that cancer cells are prevalent in the human body.
So why do some people get cancer and some people get it? It involves our immune system.
The human body has a strong immune system, which is able to recognize and remove the vast majority of cancer cells in a timely manner, preventing them from developing into real cancer.
However, cancer can develop when the immune system is compromised or when cancer cells escape the immune system's surveillance.
In recent years, a research team from the Chinese Academy of Medical Sciences has revealed a novel mechanism of tumor immune escape. They found that the ability of cancer cells to escape was linked to a gene called CSDE1.
The differential epigenetic modification and subsequent differential expression of this gene affects the ability of tumor cells to escape, thus explaining why some people still develop cancer despite their good lifestyle habits.

Cancer cells are abnormal cells that multiply wildly in the human body to form tumors.
These tumors will consume a lot of nutrients in the body, resulting in weakness and weakened immunity, which can easily lead to other diseases.
At the same time, as the tumor grows, it can also put pressure on the surrounding tissues and organs, affecting blood circulation and leading to organ failure.
What's even more terrifying is that cancer cells also have a strong ability to metastasize, and they can metastasize to other parts of the body through blood circulation or lymphatic system, continuing to destroy the function of other organs.
In the process of treating cancer, radiotherapy, chemotherapy and other means will also cause certain damage to the body.
Although these treatments can kill cancer cells, they can also cause damage to normal cells, resulting in a series of side effects, such as nausea, vomiting, hair loss, etc.
These side effects not only affect the patient's quality of life, but may also increase the psychological burden of the patient.

While cancer is scary, it is not unpreventable. Here are four tips that can help you reduce your risk of cancer:
(1) Regular physical examination
This is one of the important measures to prevent cancer. Through regular medical check-ups, we can detect abnormalities in the body in time and thus take timely interventions.
In particular, cancer screening programs, such as breast examination, colonoscopy, etc., should attract our attention.
(2) Quit smoking and drinking
Smoking and excessive alcohol consumption are both risk factors for cancer. Both harmful substances in smoke and alcohol can cause damage to the human body and increase the risk of cancer. Therefore, we should resolutely quit smoking and drinking to protect our health.
(3) Maintain a moderate amount of exercise
Exercise is one of the effective means of cancer prevention. Moderate exercise can promote blood circulation, enhance immunity, reduce stress, etc. We can choose the type of exercise that suits us, such as walking, jogging, swimming, etc., and stick to it.
(4) Rational food
Diet is closely related to the development of cancer. We should maintain a balanced and varied diet, eat more fresh fruits and vegetables, and reduce the intake of foods high in fat, sugar and salt.
At the same time, avoid eating expired and spoiled food to reduce the intake of carcinogens in food.
Preventing cancer is not that hard to do. As long as we develop good lifestyle habits, regular physical examinations, quit smoking and alcohol, maintain a moderate amount of exercise and a reasonable diet, we can effectively reduce the risk of cancer.
