Cancer Screening

The cancer screening is a preliminary cancer judgment for the human body to prevent the occurrence of cancer and timely treatment of cancer, which can effectively reduce the probability of cancer death. The cancer screening conducts physical examinations, laboratory tests, and direct or indirect visceral examinations. During the physical examination, imaging examination, nuclear magnetic resonance (MRI), ultrasound, endoscopy, laboratory examination, pathological biopsy. Basic Information Specialist classification: Oncology examination classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Tips: Pay attention to full rest and ban smoking. Normal value There were no tumor images in the image examination, no lesion images in the nuclear magnetic resonance (MRI), no radioactive concentration in the radionuclide scan, no abnormalities in the ultrasound images, no tumors found in the endoscopy, and no tumor cells in the pathological sections. Clinical significance Abnormal results: 1. Image examination An image examination of a part of the body can help the doctor determine if there is a tumor. X-ray examination is the most common way for doctors, such as chest radiographs, X-ray examination of bones, etc. to obtain a series of detailed images within the body, which can provide a basis for cancer diagnosis. 2. Nuclear magnetic resonance (MRI) can produce images similar to CT scans but with different effects, which can indicate whether there is a lesion. 3. Radionuclide scanning Oral or injection of a substance with mild radioactivity, the radioactivity level of certain organs is measured by a scanner, and an abnormal region of radiation concentration in an organ is analyzed to reflect the lesion. 4. Ultrasonic high frequency sound waves enter the body and then bounce back, which forms an ultrasound image. Reflects the internal structure of the body and indicates the lesion. 5. Endoscopy A very thin tube is observed through the throat, trachea, esophagus, intestine, vagina or uterus, and abnormal tissue or cells can be collected to indicate the presence of cancer cells. 6. Laboratory testing laboratory testing blood, cerebrospinal fluid, bowel movements and sputum, etc., may indicate the presence of certain tumors. 7. Pathological section examination to take a small piece of tissue sample or to remove the entire tumor to determine the presence of cancer, can distinguish what kind of cancer, can judge the growth of the tumor cells. Need to check the crowd: middle-aged and elderly people, long-term engaged in high-risk industry groups. Precautions Taboo before the test: pay attention to adequate rest, no smoking. Requirements for examination: Endoscopy will cause discomfort and the patient should actively cooperate with the examination. Inspection process The cancer screening conducts physical examinations, laboratory tests, and direct or indirect visceral examinations. During the physical examination, imaging examination, nuclear magnetic resonance (MRI), ultrasound, endoscopy, laboratory examination, pathological biopsy. Not suitable for the crowd Inappropriate crowd: None. Adverse reactions and risks No relevant information.
