Lateral developmental tumors are generally flat lesions originating from the intestinal mucosa.
Lateral developmental tumors usually spread laterally and superficially along the mucosal surface and rarely invade the deep intestinal wall. The tumor is most often found in the colon, is usually larger than 10 MM in diameter, and has a tendency to become malignant.
Usually, there are usually no obvious symptoms when suffering from this disease. As the disease progresses, symptoms such as changes in bowel habits, abdominal pain, and bleeding from the stool may occur. In severe cases, it may lead to conditions such as weight loss and anemia.
Due to the high likelihood of malignant metastasis in laterally developing tumors, prompt treatment is usually required once detected. Clinical treatment is mainly surgical, and endoscopic mucosal resection is usually used for laterally developing tumors confined to the mucosa.
Regular physical examination is recommended to detect abnormalities in time. Diagnosis and treatment should be carried out as soon as physical discomfort occurs to avoid untimely treatment and aggravation of the disease.
