In the face of cancer, everyone often talks about cancer discoloration.
The source of this fear is not groundless. In recent 40 years, the cancer burden in China has also increased significantly.
According to an article published in The Lancet Oncology by He Jie, an academician of China Academy of Sciences, in the past 40 years, the proportion of people in China who died of cancer has decreased from 1973— The proportion of cancer increased from 10.1% in 1975 to 24.2% in 2015, and the burden of cancer increased day by day.
Why are some cancers found late?
Some cancers are terminal as soon as they are discovered. Why?
First, the concealment of cancer itself is high. The incubation period of most cancers is long, which is very long, whether it is from oncogene mutation or from persistent infection with carcinogenic virus to the final formation of cancer. In this process, there may be no obvious clinical symptoms, which are not easy for patients to detect. Once there are perceptible clinical symptoms, they often metastasize, which is the advanced stage of cancer.
Second, patients are too negligent. Some cancers have nonspecific symptoms in the early stage, such as fatigue, cough, slight chest pain or abdominal pain, but many patients often neglect diagnosis and treatment, or the abnormal indicators of physical examination do not further clarify the cause, which delays the treatment opportunity.
Third, there is no regular physical examination. Many people feel healthy and refuse to have regular health checkups, but they don’t know that health checkups can find some cancers in time.
So which cancers are advanced as soon as they are discovered?
Pancreatic cancer is often called the king of cancer, and its survival rate is low. Most of the early pancreatic cancer has no clinical symptoms, and it is in the middle and late stage when it is diagnosed, so it is difficult to cure.
The incidence and mortality of lung cancer have increased the fastest, and it is one of the most threatening malignant tumors to people’s health and life. The symptoms of early lung cancer are often mild, and there may even be no discomfort.
The symptoms of early liver cancer generally have no obvious characteristics, and the middle and late stages will be accompanied by symptoms such as liver pain, abdominal distension, fatigue and emaciation.
These symptoms require vigilance.
British scholars published an article in The Lancet Oncology. By studying the data of 8,000 patients suffering from 12 common cancers, it was found that 13 of the 20 symptoms appeared in the early stage of cancer, including abnormal nevus, breast mass, postmenopausal bleeding, rectal bleeding, lower urinary tract symptoms, hematuria, change of defecation habits, hoarseness, fatigue, abdominal pain, lower abdominal pain, weight loss and so on. Therefore, once the above symptoms appear, ordinary people should see a doctor in time.
It needs to be emphasized that we should pay special attention to weight loss. A study published by Oxford University in the British Medical Journal on August 13th, 2020 shows that subjects who suddenly lose weight are twice as likely to develop cancer as those who don’t.
How do ordinary people avoid getting sick
Doing the following will help us stay away from cancer.
In daily life, people need to pay attention to stay away from ionization and ultraviolet radiation.
Develop a reasonable dietary structure and balanced nutrition. Control the intake of red meat food, choose rough grains, and increase the intake of fresh fruits and vegetables and low-calorie foods.
Keep moving properly. Adults should try to reduce sedentary time, and exercise time is recommended to be about 150 minutes per week.
Develop good habits of work and rest. Guaranteed daily 7-mdash; 9 hours of sleep, it is recommended to sleep from 10 pm to 6 am the next day.
Pay attention to controlling drinking and quitting smoking, and keep a good attitude. Learn to deal with things positively and peacefully in life, and don’t be overly anxious about everything.
Regular physical examination, arrange targeted cancer screening every year to achieve early detection and early treatment. (Source: Popular Science China)
