Can abdominal CT scan detect colorectal cancer and stomach cancer?

Can abdominal CT scan detect colon cancer and stomach cancer?

1. Abdominal CT scans may not necessarily detect colorectal cancer or gastric cancer. If you have any suspected symptoms, it is recommended to go to the hospital for further examination as soon as possible.

2. Abdominal CT scan is an auxiliary examination to check whether there are abnormalities in the abdominal cavity through CT. It can be used to evaluate whether the abdominal organs have inflammation, tumors, perforations, effusions, etc., to help clinical diagnosis of digestive system malignancies such as colorectal cancer or gastric cancer. When there are space-occupying lesions in the digestive tract, abdominal CT scan is performed. Otherwise, the stomach and colon are not within the scope of the examination and cannot be examined.

3. Patients with colorectal cancer may experience diarrhea, constipation, blood in the stool, abdominal masses, etc. Patients with gastric cancer may experience abdominal discomfort, black stools, vomiting, hematemesis, dysphagia, etc. If there are suspected symptoms, it is recommended to go to the hospital for gastroscopy, colonoscopy, biopsy pathology, etc. as soon as possible, and receive treatment after diagnosis.

4. Both gastric cancer and colorectal cancer should be diagnosed and intervened as early as possible to avoid serious harm to health after the spread of cancer cells.
