Which physical examination items can find early cancer?

1. Endoscopy is an effective method to diagnose early digestive tract tumors.

Endoscopy generally refers to gastroscope and enteroscope, especially enteroscope. Many people are worried about the pain or unexpected situation during the examination, resulting in resistance. As we all know, in clinical screening, endoscopy such as colonoscopy is a more effective and ideal diagnostic method. Because in the process of examination, the doctor can directly observe whether there is any abnormality in the intestine with the naked eye. If lesions are found, doctors can use special biopsy forceps at the front end of colonoscopy to take tissue for biopsy, and early diagnosis of malignant lesions through pathological examination can effectively find early asymptomatic digestive tract tumors. With the continuous progress of medical technology, the diameter of colonoscopy tube is smaller than before, the material is softer, and the degree of pain during examination is not as high as we thought. If the tolerance of colonoscopy is not good, many hospitals also carry out painless colonoscopy, which can alleviate or even eliminate the pain of patients.

2. The difference between low-dose spiral CT and ordinary chest film.

In the routine physical examination of lung cancer, there are generally chest radiographs, which can find some lesions of lung, heart, mediastinum and pleura, but chest radiographs can hardly find early lung cancer lesions with a diameter below 1 cm, so the missed diagnosis rate of early lung cancer lesions found by chest radiographs is high. Compared with traditional chest film, low-dose spiral CT has obvious advantages in finding early lung cancer, and can find small nodules below 1 cm, which greatly improves the detection ability of early lung cancer, and the radiation dose is not as large as that of conventional CT, so it is a good choice for high-risk groups of lung cancer. Studies have confirmed that low-dose spiral CT screening in high-risk groups of lung cancer can reduce the mortality rate of lung cancer by about 20% and the overall mortality rate by 7%, which is of great significance for finding early lung cancer.

3. What is breast molybdenum target?

Speaking of screening methods for breast cancer, I think many people have heard of molybdenum target, and most people are stunned by this seemingly tall name. How to do this test? Is it expensive? This is a common problem that puzzles everyone. Let's know what molybdenum target inspection is today.

In fact, in general, mammography is one of the authoritative means to find early asymptomatic breast cancer, and it is a screening means to prove that the risk of death can be reduced by early detection of breast cancer. Therefore, it is suggested that women over 40 ~ 45 years old should have a molybdenum target combined with B-ultrasound examination every 1 ~ 2 years to reduce the possibility of missed diagnosis.

4. What is the detection of tumor markers?

In daily life, many people think that "a drop of blood can detect cancer" through small advertisements distributed around the internet, media and hospitals. The concept here is tumor marker detection. In fact, this statement is very unreliable. Tumor markers are biochemical substances produced by tumor tissues themselves to reflect the existence and growth of tumors. It can be tested in blood in hospital, mainly including carcinoembryonic antigen, carbohydrate antigen, natural autoantigen, cytokeratin, tumor-related enzymes, hormones and some oncogenes. It is often used as an auxiliary reference index in clinical diagnosis and treatment to help clinicians determine the biological characteristics and disease stages of tumors, but it is not the fundamental standard for cancer diagnosis. Many people are very nervous when they see the arrow behind the value on the laboratory sheet, and they are worried whether the test results are beyond the normal range and they will get cancer. In fact, the result may not be a malignant tumor.

In the view of Duomu Health, the fundamental reason why Japanese medical tourism is popular among Chinese people is that the overall technical service level of domestic hospitals can not meet the requirements of the people. Expensive medical expenses, medical expenses, incurable diseases, difficulties in hospitalization and the demand for doctors combine to cause China people to go abroad to seek services that meet their needs. If there is an opportunity, you should bring your family to Japan for an examination.
