Mr. Lin, 51 years old, has a long history of smoking. Although he is not too obese, his BMI value is 27.5, which is considered obese. As a businessman, he often works overtime. He feels that working on weekdays is already too tiring, so he just wants to rest and relax on holidays. He often comforts himself by eating delicious food and does not develop exercise habits.
Colonoscopy revealed 3 polyps and 1 had developed into colorectal carcinoma in situ.

Recently, he went to the health management hospital to arrange an advanced imaging health examination. Considering his long-term smoking history and dietary habits that favor eating high-fat foods and not liking vegetables, gastrointestinal endoscopy and low-dose pulmonary examination were specially included in this health examination. The computerized tomography examination and the imaging report on the day of the physical examination were immediately released. He had a long history of smoking and had bronchial wall thickening and mild infiltration in his lungs. The radiologist evaluated that it might be related to chronic inflammation of the lungs caused by long-term smoking.
The doctor who explained the report then performed a colonoscopy on him and found three polyps of different sizes. One of the polyps was an adenomatous polyp with a high risk of cancer, exceeding 1 cm in size. During the examination, the doctor who operated the endoscope also performed a polypectomy. After subsequent pathological examination, one of the polyps was confirmed to be a tubular adenoma and had developed into colorectal carcinoma in situ. Fortunately, it was discovered early and the cancer cells were only in the epithelial cell layer. During the polypectomy, the cancer cells were removed at the same time.

Colorectal cancer can be staged and resected in this way
Liang Chengchao, deputy director of the Health Management Hospital, explained that the staging of colorectal cancer is mainly based on the depth of tumor invasion of the intestinal mucosa, the presence or absence of lymph node invasion, and distant metastasis. At present, in the clinical treatment of colorectal cancer, the most fortunate thing is that when the colorectal cancer is discovered at stage 0 (carcinoma in situ), it only requires colonoscopy to remove the tumor. However, if the tumor is too large or the margins after resection are not clean, there will be tumors. If the cells remain, they must be surgically removed.
Almost asymptomatic, mostly discovered during health check-up
Since colorectal cancer has almost no obvious symptoms when it develops in the early stages, most of the symptoms are in the late stage when symptoms appear. Liang Chengchao pointed out that the symptoms of colorectal cancer in situ are almost asymptomatic, and most of them are discovered accidentally due to health examinations. This is why This is why high-risk groups are always urged to proactively screen early and regularly.
Pay attention to the risk factors of colorectal cancer. These people are high-risk groups.
Liang Chengchao also reminded that most people think that smoking only affects the lungs, but in fact it also increases the risk of colorectal cancer. In addition to smoking, risk factors for colorectal cancer include: age (over 50 years old), family history, ulcerative colitis or Crohn’s disease, obesity, high-fat foods, red meat, low-fiber diet and alcohol consumption, etc. , if you have the above factors, you are a high-risk group for colorectal cancer.
It is worth noting that colorectal cancer is a type of cancer that can be prevented through health check-ups, and the earlier it is detected, the higher the prognosis and survival rate. With proactive screening, as long as the disease is detected in stage 0-1 in time, the five-year survival rate can be as high as over 90%.
