What are the early symptoms of colon cancer

Transverse colon cancer is rare and easy to misdiagnose. In the late stage, it is often accompanied by invasion of surrounding organs and cannot be surgically removed, and the prognosis is poor. We must pay attention to the early symptoms of transverse colon cancer. With sufficient understanding, we can discover the problem earlier and conduct relevant examinations and treatments in time. Let's take a look at the relevant symptoms.

1. Mass type (cauliflower type, soft cancer) The tumor grows into the intestinal cavity, the tumor is large, hemispherical or spherical, easy to ulcerate and bleed, and secondary infection and necrosis. Most of this type are highly differentiated, less invasive, and grow slowly. They are more likely to occur in the right colon.

2. Infiltrative (constrictive, sclerosing) tumors surround the intestinal wall and infiltrate, with significant fibrous tissue reaction, growing along the submucosal membrane, with a hard texture, and easily causing intestinal stenosis and obstruction. This type of cell has a low degree of differentiation, a high degree of malignancy, and early metastasis. It is more likely to occur in the large intestine beyond the right colon.

3. Ulcerative tumors grow deep into the intestinal wall and infiltrate the outside of the intestinal wall. Ulcers may appear in the early stage, with raised edges and deep bottoms. They are prone to bleeding and infection, and can easily penetrate the intestinal wall. The cells are poorly differentiated and metastasize early. It is the most common type of colon cancer, and is prone to occur in the left colon and rectum.

Knowing the symptoms of transverse colon cancer, we should make an early diagnosis and treat it as soon as possible. In the early stage of transverse colon cancer, surgery is the main treatment. However, surgery can only remove the visible lesions. Cancer is a systemic disease, and there are residual cancer or regional lymph nodes. Since surgery damages the vital energy, the chance of recurrence and metastasis is very high.
