What are the main tests for diagnosing rectal cancer

The incidence of colorectal cancer is increasing among young people, especially those who need to sit at work. So, what are the examinations for diagnosing colorectal cancer? Let's ask the experts to tell us in detail about the examinations for diagnosing colorectal cancer .

If rectal cancer is suspected, visual examination should be performed first. Generally, the patient should be in the side-lying or prone position. Observe the location, characteristics, size and nature of the lumps inside and outside the anus, and whether there are ulcers and bleeding spots. Observe the changes in the size of hemorrhoids and their relationship with body position, whether the lumps have prolapsed, and their size, shape, color of the surface mucosa, whether there are ulcers, necrosis, bleeding spots, and whether the prolapsed voluntarily retracts.

Another examination for diagnosing rectal cancer is digital examination. Rectal examination is the most important method for diagnosing rectal cancer. About 80% of rectal cancers can be found through rectal examination, while about 80% of delayed diagnosis of rectal cancer do not undergo rectal examination. Rectal examination mainly checks the texture of tumors inside and outside the anus, the presence of nodules, and tenderness. For anal fistula, attention should be paid to whether there is any abnormality with the anorectal ring and whether there is sclerosis.

The necessary examinations for diagnosing rectal cancer also include anoscopy and sigmoidoscopy. Observe whether the anoscope is inserted smoothly, the size, location, shape, surface mucosal color, bleeding and erosion of the mass above and below the tooth line, and whether the rectal mucosa is loose. For patients with anal bleeding, a sigmoid colon examination is necessary. If the examination indicates inflammatory bowel disease, a further electronic colonoscopy is required.
