What tests are used to check for colon cancer

Colon cancer is a malignant tumor disease that not only has a very high incidence rate in China, but also has been increasing worldwide in recent years. It has had a huge impact on the health and daily life of many patients and friends. Next, I will introduce to you the examination methods for colon cancer:

1. Intestinal cavity examination: Use a special fiber ultrasound endoscope to fill water between the ultrasound sensor and the intestinal wall, wrap a special water bag or an air bag around the ultrasound sensor and inject water into the intestinal cavity, so that the sensor can be measured through water. The measured image shows five layers of the intestinal wall, namely the mucosal layer, the muscularis mucosa, the submucosal layer, the muscularis propria and the serosa. This is one of the methods for checking colon cancer.

2. Ultrasound section imaging diagnosis: Ultrasound examination of colon tumors can be used in the following two aspects, namely, examination through the abdominal wall or through the intestinal cavity. This is also a checkup item for colon cancer.

3. Transabdominal examination: directly examine the location, size, and relationship of the primary intestinal mass with surrounding tissues; examine metastatic lesions: including retroperitoneal and mesenteric root lymph nodes, metastatic nodules or masses, whether there are metastatic nodules in the pelvis; and whether there are space-occupying solid masses in the liver. This type of examination for colon cancer is relatively common.

The above three aspects are the relevant introduction to the question of what are the examination methods for colon cancer. I hope everyone can realize the importance of correct examination for the treatment of colon cancer. At the same time, we must pay attention to the prevention of colon cancer. I wish you all good physical and mental health.
