How long does it take for colonoscopy results to come out

Colorectal cancer is a common malignant tumor, including colon cancer and rectal cancer, and the age of onset is becoming older. Regular check-ups are a healthy choice that everyone should make. But many people want to know how long it takes to do this check-up. So, how long does it take for a colonoscopy to produce results? Let's take a look at the following introduction.

Colonoscopy is indeed a little uncomfortable, but it is still within the tolerable range, so don't worry too much. Generally, the results of colonoscopy are available on the same day, but the specific details are subject to the hospital's regulations.

Diagnosis: Colorectal cancer

In addition to colonoscopy, there are other ways to detect colorectal cancer.

1. Laboratory examination

Blood routine, complete biochemistry (liver and kidney function + serum iron), stool routine + fecal occult blood and other laboratory tests can help understand whether the patient has iron deficiency anemia, liver and kidney function and other basic conditions. Testing for blood tumor marker carcinoembryonic antigen (CEA) can help diagnose tumors. In patients with colorectal cancer, high CEA levels do not mean that there is distant metastasis; in a few patients with metastatic tumors, CEA levels are not elevated.

2. Biopsy and exfoliative cytology

Biopsy is of decisive significance for the diagnosis of colorectal cancer, especially early cancer and polyp cancer, as well as for differential diagnosis of lesions. It can clarify the nature, histological type and malignancy of the tumor, judge the prognosis and guide clinical treatment. Exfoliative cytology has high accuracy, but the sampling is cumbersome, and it is not easy to obtain satisfactory specimens, so it is rarely used in clinical practice.

The early symptoms of colorectal cancer are very subtle and can be easily overlooked. Early diagnosis is key.
