Please check the screening schedule of nine common cancers
2022-04-22
You know, cancer is no longer an incurable disease. Nearly half of cancers can be prevented, and about 1 / 3 of cancers can be cured through screening and early detection. And why are many people diagnosed with cancer already in the advanced stage? Today, I would like to introduce a special "maintenance manual", which is closely related to our own health - screening and prevention of common malignant tumors. Why does cancer come to you without a genetic history? Malignant tumors are abnormal hyperplasia after normal cells gradually mutate. In addition to the continuous growth of the tumor itself, this abnormal hyperplasia is also manifested as invasion of adjacent normal tissues and transfer to other parts of the body through blood vessels, lymphatic vessels and body cavities. The increased tumor tissue occupies and destroys normal tissues and organs, resulting in organ function damage, eventually leading to organ failure and taking away the lives of patients. Some people may ask: "no one in the family has cancer, why do malignant tumors come to me?" People's understanding of tumor pathogenesis has risen from the single factor theory of physical carcinogenesis, chemical carcinogenesis, viral carcinogenesis and mutation carcinogenesis to the comprehensive carcinogenesis theory of multi factors and multi steps. The change of tumor incidence rate is mainly affected by many factors such as population age structure, nutrition, genetics, environment, lifestyle, economic level and education level. Among them, smoking, obesity, diabetes, viral infection and unhealthy eating habits are the first reasons. Cancer prevention physical examination "found" many patients with malignant tumors. When they were diagnosed, they were already in the middle and late stage of cancer. Why did this happen? The diagnosis of malignant tumors is the unity of multiple means of diagnosis such as clinical physical examination, laboratory tests, imaging observation and pathological examination. Because many cancer patients have no obvious symptoms in the early stage, or the patients do not pay enough attention to the subtle symptoms, most cancer patients are in the middle and late stage when they are diagnosed. Therefore, we say that no matter the progress of diagnostic technology or the development of treatment methods, the "three early" still fundamentally improve the prognosis of tumor patients, that is, early detection, early diagnosis and early treatment, which are indispensable. So, if you want to find out the real culprit of this disease, the cancer prevention physical examination is very important! Cancer prevention physical examination is mainly divided into five aspects, which can be condensed into five words: physical examination. Some tumors can be detected by physical examination, such as intestinal cancer, breast cancer and thyroid cancer. Test - the meaning of blood test. Many tumors have tumor markers that can be captured by blood tests. Imaging - mainly refers to imaging examination, such as color ultrasound, CT, magnetic resonance, etc. Endoscopy mainly refers to endoscopy, such as gastroscope, enteroscope, tracheoscope, etc. This is the pathological diagnosis. Take a small piece of the abnormal tissue for pathological diagnosis, so as to determine whether it is a malignant tumor. I want to remind you that cancer prevention physical examination is not just a general physical examination, nor is it the more expensive the items, the better. It needs to be "tailored". The screening population of these common cancers is people over 50 years old, with family history of lung cancer, smoking history, cough and chest
