What is the basis for diagnosing colon cancer

We should know that colon cancer has no typical symptoms in the early stage of the disease, or the symptoms are hidden or minor, such as constipation, blood in the stool and other physical abnormalities, which are not easy to be discovered by patients and treated in time. But nowadays, what is the basis for the diagnosis of colon cancer?

Step 1: Medical history When examining each disease, the doctor first needs to ask about the medical history in detail, which is of great significance to the diagnosis of the disease. If the middle-aged or older person has unexplained weight loss, anemia, changes in bowel habits, mucus in the stool, blood in the stool, intestinal obstruction and other symptoms, the possibility of this disease should be considered.
Step 2: Physical examination Usually, after asking about the patient's medical history, a comprehensive physical examination is also required, which not only helps to correctly diagnose the disease, but also estimates the severity of the disease, the invasion and metastasis of cancer, and serves as a reference for formulating a reasonable treatment plan.
The diagnosis of colon cancer is of great significance for early detection of the disease and timely treatment, which is very beneficial to the recovery of the disease. I hope that patients can receive accurate diagnosis and timely treatment.
