What are the examination methods for intestinal cancer?

The common examination methods of intestinal cancer include digital rectal examination, endoscopy (divided into anoscopy, sigmoidoscopy and colonoscopy according to the location and scope), fecal occult blood test, tumor marker examination, imaging examination (barium meal X-ray, CT, MRI, PET-CT) and fecal DNA detection technology recommended as routine screening for intestinal cancer in recent years. Among them, digital rectal examination means that doctors use their fingers to check whether there is a tumor in the rectum. This examination method can find 60%-70% of rectal cancer, which is a relatively simple, economical and effective examination method. However, the privacy of digital rectal examination is low, which leads many people to ignore this step automatically during physical examination. As a new technology for detecting intestinal cancer-fecal DNA detection technology, Huada Gene has developed a non-invasive gene detection for intestinal cancer in China, and selected three genes closely related to the occurrence and development of intestinal cancer to detect whether their methylation is abnormal, with a sensitivity of 88% and a specificity of 92%. Huachangkang has the characteristics of simple operation, strong privacy and high crowd acceptance, which provides a new choice for people who are afraid of colonoscopy and busy office workers.
