In brief: Colon cancer

One of the most common causes of anemia in adults is colon cancer.
In this type of cancer, one can slowly bleed over many months slowly making him/her more anemic. If a small cancerous polyp is found early, it can be removed and the cancer treated before it spreads. That is why a colonoscopy is recommended in unexplained cases of anemia.

Your doctor is looking for a reason for your anemia and one possibility is that you have been bleeding from your GI tract without noticing it.
There are multiple causes for this ranging from benign to cancer.
