With the gradual improvement of people’s health awareness, medical checkups have become a must-do homework for many people every year. Many people believe that if you pass the physical examination, it means that your health is fine, at least for a year, you can rest easy. In fact, many people have been diagnosed with tumors soon after medical checkups, and tragedies have happened as usual. Today, I would like to give you a brief introduction of cancer prevention physical examination: health physical examination ≠ cancer prevention physical examination Health physical examination is not equal to cancer prevention physical examination. The focus of regular health physical examination is mainly on physical examination, cardiovascular disease, chronic liver disease and diabetes, but not on cancer screening. Cancer prevention medical checkup is a more professional medical checkup, which is a whole body examination of the examinees by oncology professional physicians through professional technical means and methods, with the purpose of discovering early tumors. Up to now, there are clear diagnostic methods for each tumor, and different tumor types require different examination methods. For example, tumor examination of parenchymal organs requires imaging, cavity organs require endoscopy, body surface tumors require palpation or ultrasound examination, etc. What professional examinations are required for cancer prevention physical examination In addition to routine examination, cancer prevention physical examination must be combined with professional examination means. For example, some early cervical cancers have smooth cervical surface and the lesion area cannot be detected by naked eye observation, so if cervical cytology smear examination is not done, early cancers will not be detected. Also, diagnostic examinations like breast palpation, regardless of whether the examiner is professional enough, will not have much significance in detecting early microscopic cancers of the breast. It must be supplemented by breast ultrasound and X-ray examination. The significance of cancer prevention physical examination As a professional oncologist tells you, early detection of cancer is crucial, and 1/3 of cancers can be cured through early detection. And cancer prevention physical examination is an important way to actively detect early cancer, and it is also a key step to enable patients to get the best treatment effect. Conducting regular professional cancer prevention medical checkups is still the best way for human beings to fight against cancer. Through medical checkups, many precancerous diseases can be detected, such as severe cervical erosion, acromegaly infection, chronic gastric ulcer, cystic hyperplasia of breast, etc., which should be actively treated or closely followed up, and do not think that it is safe to ignore because it is not cancer. The interval of cancer prevention checkups Healthy people, especially those aged 35-40 or above, should preferably have a regular checkup once a year followed by a cancer prevention checkup; people who are consciously in sub-health after 40 years old and various high-risk groups should be screened for cancer once every six months, because they may be hit at any time, and the growth time of many solid tumors of cancer needs to grow to detectable size is about half a year, so they need Semi-annual screening. People who already have symptoms of precancerous lesions, these people need to monitor their condition in real time, once every three months to ensure safety. These include people with chronic hepatitis B combined with cirrhosis; people with severe colorectal polyps; and people with a long history of smoking who suddenly start to have chronic cough and chest pain.
