SERVICES > Rectal polyps / tumours

Rectal polyps are protuberances in the inner lining of the bowel. The innermost lining of the musosa comprises of cells which overgrow and in doing so, heaps up on itself forming a surface elevation. The significance of polyps is that they can transform into cancer and this process accounts for 75% of colorectal cancers. The risk of transformation is proportional to size or the grade of dysplasia, i.e. the degree of abnormality in the behavior of surface mucosal cells that are clumped together.
