Intestinal tumours

author/s: Dr Mª Carmen Peña Cala

 

What is a tumour?

A tumour is an abnormal bulging of an organ or part of the body.

 

How are tumours classified?

Based on their histology, tumours can be classified as benign or malignant.

 

What are the most common intestinal tumours and how are they treated?

The intestine is formed by several layers of tissues, and tumours can originate in any part of these layers. Within the benign tumour group, polyps are the most common.

Within the malignant tumour group, colon and rectal cancer are the most frequent, in both men and women. These tumours usually have an invasive nature and many of them are diagnosed first due to the complications they present. The treatment of colon cancer is surgical, complemented sometimes with chemotherapy and radiotherapy.
