How harmful is colon cancer?

Experts point out that the harm of colon cancer mainly refers to its mortality rate. In my country, the mortality rate of colon cancer is only after lung cancer and liver cancer. Of course, as a type of cancer, its harm is not limited to this one, such as the metastasis it can cause. Below, we will introduce some of the more common harms of colon cancer:

1. As the cancer cells of colon cancer rupture and lose blood, toxins are absorbed, which leads to anemia, fever, fatigue, weight loss, edema and other symptoms in patients. The most obvious harm caused by colon cancer to patients is anemia and weight loss.

2. The intestinal cavity of the left colon is relatively narrow, and the feces become very viscous and formed after passing through it. In addition, the cancer occurring in this part is invasive cancer. Since the intestinal cavity is annular and narrow, patients will experience intestinal obstruction earlier, and in severe cases, acute obstruction will occur.

3. The right colon cavity is relatively wide, and the stool becomes very thin after passing through it. The colon is rich in blood supply and lymph, and has strong absorption capacity. Most cancer cells are soft cancers, which are prone to ulceration and necrosis, leading to bleeding and infection. Clinically, the symptoms are mainly poisoning, and in severe cases, intestinal obstruction may occur.
