What are the symptoms of early colon cancer

Colon cancer is a common malignant tumor of the digestive tract, ranking second among gastrointestinal tumors. The most common sites are the rectum and the junction between the rectum and the sigmoid colon, accounting for 60%. The incidence is mostly after the age of 40, with a male to female ratio of 2:1. What are the early symptoms of colon cancer? Some epidemiological studies on colon cancer have shown that social development status, lifestyle, and dietary structure are closely related to colon cancer, and there are phenomena suggesting that there may be differences in environmental and genetic factors affecting the incidence of colon cancer in different parts and age groups. Environment (especially diet), genetics, physical activity, occupation, etc. are possible etiological factors that affect the incidence of colon cancer.

What are the early symptoms of colon cancer?

(1) There may be symptoms such as bloating, discomfort, and indigestion, followed by changes in bowel habits, such as increased bowel movements, diarrhea or constipation, and pre defecation abdominal pain. Later on, there will be mucous stools or mucous purulent bloody stools, which are the earliest symptoms of colon cancer.

(II) Symptoms of intestinal obstruction: It is characterized by incomplete or complete low-level intestinal obstruction symptoms, such as abdominal distension, abdominal pain (bloating or cramping), constipation or constipation. Physical examination shows abdominal distension, intestinal type, local tenderness, and strong bowel sounds can be heard.

(3) Early toxic symptoms of colon cancer: Due to tumor ulceration, blood loss, and toxin absorption, patients often experience symptoms such as anemia, low-grade fever, fatigue, weight loss, and edema, especially anemia and weight loss.

(IV). The early symptoms of colon cancer include abdominal mass in patients with colon cancer: since the incidence rate of the disease is the highest in the middle age and above, we should be vigilant and consider the possibility of colon cancer if there are any of the following symptoms in the middle age and above.

Warm reminder: There may be differences in the environmental and genetic factors that affect the incidence of colon cancer in different parts and age groups. Environment (especially diet), genetics, physical activity, occupation, etc. are possible etiological factors that affect the incidence of colon cancer.
