Don't be careless, these symptoms may be signs of cancer

In the face of cancer, everyone often talks about cancer discoloration.
The source of this fear is not groundless. In the past 40 years, the burden of cancer in China has also increased significantly.
According to a paper published by He Jie, academician of the Chinese Academy of Sciences, in The Lancet Oncology: In the past 40 years, the proportion of Chinese people who died from cancer has increased from 10.1% in 1973-1975 to 24.2% in 2015. The burden of cancer Increasingly.
Why some cancers are found in advanced stages
Some cancers are at an advanced stage as soon as they are discovered. Why?
One is the hidden nature of cancer itself.
Most cancers have a long incubation period, whether it is from oncogene mutations or continuous infection with cancer-causing viruses, to the final form of cancer, it is very long.
During this process, there may be no obvious clinical symptoms, and the patient is not easy to detect. Once the perceptible clinical symptoms appear, metastasis often occurs, and the cancer is already in the advanced stage.
The second is that the patient is too negligent.
Some cancers have unspecific symptoms in the early stage, such as fatigue, coughing, mild 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 timing of treatment.
Third, there is no regular physical examination.
Many people feel that they are in good health and refuse regular health check-ups. They do not know that health check-ups can detect some cancers in time.
So which cancers are late when they are discovered?
Pancreatic cancer is often called the king of cancers, with a low survival rate. Most early pancreatic cancers do not have any clinical symptoms. When they are diagnosed, they are already in the middle and advanced stages and are difficult to cure.
Lung cancer has the fastest increase in morbidity and mortality. It is one of the most threatening malignant tumors to the health and life of the population.
The symptoms of early lung cancer are often mild and may not even cause any 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 weight loss.
These symptoms need to be vigilant
An article published by a British scholar in "The Lancet Oncology" found that out of the 20 types of symptoms, 13 of the 20 types of symptoms appeared in the early stages of cancer, including abnormal moles, breast lumps, Postmenopausal bleeding, rectal bleeding, lower urinary tract symptoms, hematuria, changes in bowel habits, hoarseness, fatigue, abdominal pain, lower abdominal pain, weight loss, etc.
Therefore, once the above symptoms occur, ordinary people should consult a doctor promptly.
Need to emphasize one point: pay particular attention to weight loss.
A study published by the University of Oxford in the British Medical Journal on August 13, 2020 showed that subjects with sudden weight loss are twice as likely to develop cancer as subjects without sudden weight loss.
How do ordinary people avoid illness
Doing the following points will help keep us away from cancer.
In daily life, people need to keep away from ionization and ultraviolet radiation as much as possible.
Develop a reasonable diet structure and balanced nutrition.
Control the intake of red meat food, choose crude grains, and increase the intake of fresh fruits and vegetables and low-calorie foods.
Keep moving properly.
Adults try to reduce the time spent sitting for a long time. The recommended exercise time is about 150 minutes per week.
Develop good work and rest habits.
To ensure 7-9 hours of sleep a day, it is recommended to sleep from 10 pm to 6 am the next morning.
Pay attention to control drinking and quit smoking, maintain a good attitude.
Learn to deal with things positively and peacefully in life, and don't be overly anxious about everything.
Regular physical examinations and targeted cancer screenings are arranged every year to achieve early detection and early treatment.
