Types of Colon Cancer
Adenocarcinoma is the most common type of colon cancer but there are many other types of colon cancer as well. Examples include sarcoma, melanoma, carcinoid, and lymphoma. Here, you can learn more about each type of colon cancer.

Malignant Melanoma of the Colon and Rectum
When most people think of malignant melanoma, the first thing that comes to mind is skin cancer. But malignant melanoma can occur in a lot of places, including the colon and rectum.

Mucinous Adenocarcinoma of the Colon and Rectum
Scientists think that the presence of mucus allows cancer cells to spread faster. As a result, mucinous adenocarcinomas are considered more aggressive than regular adenocarcinomas and are harder to successfully treat. Mucinous adenocarcinomas account for about 10-15% of all adenocarcinomas.

Signet Ring Cell Adenocarcinoma of the Colon and Rectum
Signet ring cell adenocarcinomas are considered more aggressive than regular adenocarcinomas and are harder to successfully treat. The signet ring cell form is very uncommon and accounts for about 0.1% of all adenocarcinomas.

Leiomyosarcoma of the Colon and Rectum
Colorectal sarcomas occur in the smooth muscle of the colon and are called leiomyosarcomas. Leiomyosarcomas account for less than two percent of colorectal cancers and have a fairly high chance of metastasizing.

Adenocarcinoma of the Colon and Rectum
Adenocarcinoma is the most common type of colorectal cancer. Learn what "adenocarcinoma" means, where it comes from, what its subtypes are, and more.

Carcinoid Tumors of the Colon and Rectum
Carcinoid tumors are more likely to occur in the rectum than in the colon and don't usually spread to other parts of the body. Carcinoid tumors account for less than 1% of all colorectal cancers.

Lymphoma of the Colon and Rectum
Lymphoma of the colon and rectum accounts for less than half a percent of all colorectal cancers. A lymphoma is like a city whose mayor has gone mad and designs a machine to crank out drones who have one purpose: to make sure he stays in office.
