Colorectal cancer diagnosis

1. The differential diagnosis of colon cancer is mainly from inflammatory diseases of the colon, such as intestinal tuberculosis, schistosomiasis, granuloma, amebic granuloma, ulcerative colitis and colon polyposis, etc. The key points of clinical differentiation are the duration of the disease, parasites in stool examination, the morphology and range of lesions found in barium enema examination, etc. The most reliable differentiation is through colonoscopy and biopsy.

Periappendiceal abscess may be misdiagnosed as cecal cancer (colon cancer), but the blood count of this disease shows increased white bowel movement and neutrophils, without cachexia such as anemia and emaciation. A barium enema examination can confirm the diagnosis.

2. Rectal cancer is often misdiagnosed as hemorrhoids, bacterial dysentery, chronic colitis, etc. The misdiagnosis rate is as high as 60% to 80%, and the main reason is that the necessary examinations are not performed, especially digital rectal examination and proctoscopy.

3. Other colon tumors such as colorectal carcinoids are asymptomatic when the tumor is small, but may rupture when the tumor grows larger, and symptoms very similar to those of colon adenocarcinoma may appear; malignant lymphomas originating in the colon have diverse lesion morphologies and are often difficult to distinguish from colon cancer. Tissue smear biopsy should be performed to differentiate them.

The above is an introduction to "How to diagnose rectal cancer?" When the above symptoms appear, the patient should go to a regular hospital for treatment. Early detection and early treatment can effectively cure rectal cancer. People who are related to the pathogenic factors of rectal cancer are advised to take preventive measures for rectal cancer.
