Adenocarcinoma is the most common colon cancer type, but others include melanoma, lymphoma, and carcinoid. Browse these articles to learn more about each type of cancer.
Types of Colon Cancer
Adenocarcinoma is the most common type of colon cancer but there are many other forms as well. Examples include leiomyosarcoma, lymphoma, melanoma, and neuroendocrine tumors. Here, you can learn more about each type of colon cancer.
Adenocarcinoma
Adenocarcinoma is the most common type of colon cancer.
Aggressive Neuroendocrine Tumors
Aggressive neuroendocrine tumors account for about four percent of all colon cancers. The average age at diagnosis is 65, and they seem to favor the right (ascending) colon.
Carcinoid Tumors
Carcinoid tumors account for less than one percent of all colon cancers and don't usually spread to other parts of the body.
Leiomyosarcoma
Leiomyosarcomas account for less than two percent of colon cancers and have a fairly high chance of spreading to other parts of the body.
Lymphoma
Lymphoma accounts for less than half a percent of all colon 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.
Malignant Melanoma
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.
Mucinous Adenocarcinoma
Mucinous adenocarcinomas are considered more aggressive than regular adenocarcinomas and are harder to successfully treat.
Signet Ring Cell Adenocarcinoma
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.
