In recent years, affected by the continuous growth of cancer incidence rate and high mortality rate in the mainland, more and more people have begun to fear cancer, and even have a serious fear of cancer.
Especially in recent years, the Internet is very developed, there are many people used to the Internet to search for physical discomfort symptoms, when they see the word cancer in front of their eyes, whether they have cancer or not, they will immediately fall into a state of despair!
Because of this, many physical examination institutions have seen business opportunities, and they have launched a variety of physical examination packages, ranging from hundreds of yuan to thousands of yuan. Many people are affected by the psychology of cancer, and they willingly take out their wallets, hoping that ordinary physical examinations can help them fully understand their health conditions and screen out possible cancerous changes.
But can a normal physical examination really detect cancer? wrong!
The so-called general physical examination, in fact, is physical screening, which does include a variety of examination items, such as imaging tests, blood routine screening, routine examination of bowel and urine, three high disease tests, liver and kidney function tests and so on.
This does have a certain screening effect for ordinary acute and chronic diseases, and many diseases can be exposed in ordinary physical examination.
However, there are certain difficulties in screening cancer through these ordinary physical examinations.
Of course, it cannot be denied here that the ordinary physical examination project may indeed expose some cancerous changes, such as thyroid cancer, breast cancer, etc., which may be found in ultrasound. In addition, some hematopoietic system cancers, bone marrow proliferative malignant changes, etc., may show abnormalities in the blood routine.
However, the internal organs become cancerous and cannot be detected by routine physical examinations. Because the lesion is very small at the beginning of cancer, and there is no damage to organ function, it is difficult to find cell carcinogenesis in ordinary CT and ultrasound. As long as the cancer can be detected by ordinary ultrasound and CT, it has generally grown to a certain extent, and even entered the middle and advanced stages.
In addition, the carcinogenesis of the internal cavity organs of the body, such as esophageal cancer, stomach cancer, colorectal cancer, etc., may only be the color change of the mucous membrane, erosion or ulcer in the initial stage, and ordinary CT can not be found at all. Only a professional endoscopy may reveal potentially suspicious lesions, but the nature of the lesions cannot be judged simply by looking at them.
In clinical view, the screening method that is really suitable for cancer is actually: anti-cancer screening!
Cancer screening does not specifically refer to a certain kind of examination, it refers to people with high risk factors for cancer, such as people with a family history of cancer, a history of cancer-related chronic diseases, people over the age of 45 years old, living in areas with high incidence of cancer, etc., the probability of cancer is relatively large, and targeted cancer examinations are required on a regular basis;
That is to say, the doctor will formulate a targeted examination plan according to his actual situation. To take a simple example, if you have a family history of stomach cancer, a history of chronic stomach disease for many years, and an age of 45 years old, you need to seek regular medical attention for gastroscopy, and when you find that you can find a lesion, you also need to take tissue for pathological biopsy according to the doctor's recommendation.
So in general, you can't pin your hopes on ordinary physical examinations, knowing that cancer is a very cunning disease. Therefore, if you meet the high-risk conditions for cancer, you should tell the doctor your details completely before the examination, and then follow the plan formulated by the doctor to carry out the next step of the fine examination.
