How Is Tubular Adenoma Treated. Home Health Conditions & Diseases. Mild to moderate, or low-grade dysplasia means that the tissue is only mildly abnormal. High-grade or severe dysplasia indicates the tissue more closely resembles cancer. Sessile serrated adenomas, traditional serrated adenomas and adenomatous polyps are pre-cancerous.

Foci of dysplasia/carcinoma are fairly commonly encoun-tered. High grade dysplasia or invasive carcinoma is associated with 12–47% of the lesions.

Since you had an adenoma, you will need to have a colonoscopy every so often to make sure that you don’t develop any more adenomas. If you have a tubular adenoma, traditional serrated adenoma, or sessile serrated adenoma without high grade dysplasia you may not need colonoscopy for another 5.
