Pediatric Colorectal Cancer
Cancer that starts in the colon or in the rectum is known as colorectal cancer.
When a child has cancer that starts in the colon or in the rectum, this type of cancer is known as colorectal cancer. Colon cancer and rectal cancer are typically grouped together because they share so many of the same characteristics.
There are several types of colorectal cancer, including:
- Adenocarcinomas – the most common type of colorectal cancer, this type of cancer begins in the cells that makes mucus that lubricates the inside of the colon and rectum
- Carcinoid tumors – this type of cancer begins in a special type of cell in the intestine that produces hormones
