There are detailed differences in colon cancer diagnosis technology for women

There are certain differences in tumor biology between female and male patients with colon cancer, and there are also some subtle differences in diagnosis.

Digital rectal examination

Currently, digital rectal examination is still the most basic and important examination method in a series of examinations before colon cancer surgery, and this also applies to female patients.

Endoscopy

Fiber colonoscopy is currently the most effective, safest and most reliable method for diagnosing lesions in the large intestine, and can detect most early colon cancers.

Laboratory tests

Laboratory tests such as fecal occult blood test, hemoglobin test and serum carcinoembryonic antigen (CEA) test are also commonly used in the diagnosis of colon cancer.

Imaging and Ultrasonography

Imaging examinations include CT, MRI, and ultrasound. Since the vagina and rectum of female patients are adjacent, transvaginal ultrasound is also an ideal examination method. In addition, the scanning field of view is larger than that of transrectal ultrasound. At the same time, accurate positioning diagnosis can be made for intestinal stenosis lesions and high rectal lesions that are limited by transrectal ultrasound diagnosis, making up for the limitations of transrectal ultrasound. In addition, vaginal ultrasound during gynecological examinations can also be used as an important way to detect asymptomatic rectal tumors in the early stage.
