Doctors do not completely understand what causes adenocarcinoma, or any type of cancer. Specialists have speculated risk factors and likely causes depending on the location of the adenocarcinoma.
For instance, these are a few of the common risk factors for what causes adenocarcinoma in the colon (colon cancer):
- Previous cancer in the colon/rectum
- History of polyps
- Inflammatory disorders (IBD, Crohn’s Disease)
- Ethnic background
- Diet and exercise habits
- Alcohol intake
Are Polyps Causes of Adenocarcinoma?
In some parts of the body, polyps can form in the lining of an organ. This exaggerated growth of cells may become cancerous over time and may be one of the causes of adenocarcinoma. Still, doctor’s are not certain why these polyps become cancerous.
