The hazards of colon cancer and rectal cancer

Experts point out that the harm of colon cancer and rectal cancer mainly refers to its mortality rate. In my country, the mortality rate of colon cancer and rectal 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 common harms of colon cancer:

The dangers 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.

The dangers of rectal cancer

1. Due to the blood loss and toxin absorption caused by the ulceration of rectal cancer tumors, patients with rectal cancer often experience anemia, low fever, fatigue, weight loss, edema and other symptoms. The harmful manifestations of rectal cancer are particularly prominent in anemia and weight loss.

2. The occurrence of left-side rectal cancer is also caused by the harm of rectal cancer. The intestinal cavity of the left colon is relatively narrow, and the feces have become viscous and formed here. In addition, this part is mostly invasive cancer, and the intestinal cavity is often annular and narrow. Therefore, clinically, patients with rectal cancer will have symptoms of intestinal obstruction earlier, and some patients with rectal cancer may even have acute obstruction.

3. Another hazard of rectal cancer is right-sided rectal cancer. The right-sided colon cavity is wider, the stool is thinner, the colon is rich in blood and lymph, and has a strong absorption capacity. Cancers are mostly soft cancers, which are prone to ulceration, necrosis, bleeding and infection. Therefore, the clinical manifestations of rectal cancer are mainly poisoning symptoms. However, when the condition of rectal cancer worsens, intestinal obstruction may also occur.

4. Abdominal masses are also caused by the harm of rectal cancer. They are hard masses that are infiltrated and adhered to the tumor or the omentum and surrounding tissues. Some patients with rectal cancer may have a certain degree of mobility along the intestinal tract. In the late stage, the tumor infiltration of rectal cancer is more serious and the mass may be fixed.
