What are the common factors that cause colon cancer?

What are the common factors that cause colon cancer? Many patients have difficulty in treatment because they do not know the cause of their disease. Let us follow the experts to learn about the factors that cause colon cancer .

1. Age: It is generally believed that young patients with colon cancer have a poor prognosis, especially those under 30 years old. Specific analysis shows that young people have no obvious clinical symptoms, and most of them are diagnosed in stage III or IV, so the chance of radical surgery is relatively low.

2. Gender: It is generally believed that the prognosis of men and women is different due to anatomical and physiological differences, and the prognosis of men is worse than that of women. A multi-factor analysis of 743 cases of colon cancer at the Institute of Oncology of Zhejiang University showed that the 5-year survival rate of women over 65 years old was significantly better than that of men (69%, 60%, P<0.01). This phenomenon is more obvious in rectal cancer. In cases of colon cancer, the 10-year survival rate of female patients is slightly higher than that of male patients.

3. Location of onset: The location of colon cancer also affects the prognosis. It is generally believed that the farther from the anus, the better the prognosis. The median survival time of colorectal cancer is 80.19±1.87 months and 72±6.48 months respectively. The 5-year and 10-year survival rates of the former are 15 percentage points higher than those of the latter. In Dukes C stage patients with lymph node metastasis, the prognosis of colon cancer is significantly better than that of rectal cancer. This is a factor that causes colon cancer.

4. Course of disease: The symptoms of patients are mainly based on their own statements, and there is a lack of objective indicators. It is generally believed that the prognosis of patients without symptoms (discovered by census, etc.) is significantly better than that of patients with symptoms. The length of the course of disease after the onset of clinical symptoms is also related to the prognosis. The longer the course of disease, the more serious the development of the lesion, and the worse the prognosis. Most of the time, the course of disease is prolonged due to misdiagnosis, which creates time conditions for tumor growth. In addition, the tumor cell doubling time is short, resulting in rapid development of the disease, which makes most colon cancers lose the best treatment opportunity. This is also a factor in causing colon cancer.

The above is an introduction to the factors that cause colon cancer. Through the above content, have you learned some relevant knowledge about colon cancer? I hope the above content can be helpful to you, and I also hope that patients can actively treat and recover soon!
