How often is it better for ordinary people to do cancer screening? Doctor: It depends on the individual situation

Do you know why the cancer mortality rate remains high and the prognosis is so poor? The answer is only five words: early detection is difficult!

Clinically, more than 4 million　　new cancer patients are diagnosed each year in China . But unfortunately, nearly 2/3 of the patients are not detected in the early stage, and the cancer has even reached the middle and late stages, with serious complications.

　　Only a small number of patients are extremely fortunate, and cancer screenings or other screenings have found abnormalities in their bodies and are eventually diagnosed with cancer.

　　After entering the middle and late stages of cancer, due to the extensive spread and metastasis of cancer cells , even if there are treatment measures such as radiotherapy and chemotherapy, targeted drugs and immunotherapy, the prognosis of patients is often unsatisfactory. In just a few months, a year, or 3 years , he passed away due to completely uncontrollable cancer, organ failure, complications, etc.

　　Therefore , the clinic has always emphasized the importance of early detection and early treatment of cancer. However, in the early stage of cancer, the cancer cells did not cause substantial damage to the organs, nor did they damage the function of the organs, so most of the cancers are in the stage of carcinoma in situ and local invasive cancer, and the patient's body has no typical symptoms . There may even be no exceptions.

　　Therefore, if you want to detect cancer early, the most indispensable link is: cancer screening!

　　Affected by the high incidence and mortality of cancer in China in recent years, hospitals and physical examination centers in many regions have launched anti-cancer screening programs. The so-called anti-cancer screening does not refer to a specific inspection item, but an inspection for a certain type of cancer. That is to say, it is different from physical screening, which is a targeted examination item.

　　From a clinical point of view, not everyone is suitable for cancer screening, because everyone has different chances of developing cancer. Cancer screening for ordinary people is not only a waste of personal money, but also a waste of medical resources, which is a meaningless examination. The people who are really suitable for cancer screening are actually high-risk groups of cancer.

　　Judging from the current clinical data, there are many high-risk groups of cancer, such as long-term heavy smoking and alcoholism, family history of cancer, age over 45, specific occupational history (such as frequent exposure to ionizing radiation, industrial waste gas, chemicals), Those with a history of chronic diseases (such as atrophic gastritis, viral hepatitis, chronic cervicitis), viral infections (such as hepatitis B virus or hepatitis C virus, EB virus infection, HIV virus infection, HPV virus infection), etc., belong to the high-risk group of cancer .

　　When seeking medical examination, patients cannot blindly screen, but need to inform the doctor in detail about their disease and family medical history, age, physical symptoms and other information , and then carry out relevant screening according to the doctor's recommendations. For example and the best way to screen for bowel cancer is colonoscopy!

　　Under normal circumstances, when no abnormality is found in one examination, doctors often recommend that patients undergo the next screening 2-3 years later , and some examination items will have a longer interval. However, if any abnormality is found in this examination, timely intervention and treatment are required, and the time for later reexamination is shortened.

　　All in all, we should follow the doctor's advice and arrangements as to which cancer screening should be performed and how long the interval between each cancer screening should be. Because each person's actual situation is different, and the probability of getting cancer is also different, it cannot be generalized.

　　In addition, everyone must be clearly aware that cancer screening is aimed at screening high-risk groups of cancer, so if we do not meet the conditions, we do not need to worry too much, and we can do regular physical examinations.
