Colorectal Cancer

Cancers of colon and rectum frequently present with bleeding in stools, pain during passing stools and anemia. Suspected patients need to undergo colonoscopy and biopsy.

A biopsy is the test for confirmation of cancer. After confirmation staging is done by CECT and MRI in cases of rectal cancers.PET CT may also be required in select cases.

Treatment starts with the intention of curing the patient and also preserving the continence and thereby avoiding the permanent stoma. To preserve the continence sphincter has to be free from disease and MRI is the best tool to confirm this.

At Oncoxpert we use all advanced techniques like neoadjuvant chemoradiation, Intersphincteric resection with coloanal anastomosis to preserve the continence.
