Tubulovillous adenoma, TVA, is a type of polyp that grows in the colon and other places in the gastrointestinal tract and sometimes in other parts of the body. These adenomas may become malignant (cancerous).
TVAs are considered to have a higher risk of malignant transformation than tubular adenomas.
