Thank you for your question.
Yes it may cause other signs other than anemia.
Colon cancer may only cause anemia as the first sign.
Stomach cancer usually will also cause a lot of weight loss, nausea and vomiting at times.

Platelet count being on the higher side and the hemoglobin a little lower most likely means that she could be bleeding from somewhere.
It may not be cancer or anything serious but that is something that must be considered and ruled out.
Also an upper GI endoscopy is also required.
Stool for occult blood is also required.
Yes ferritin so low and hemoglobin low means you are most likely bleeding from somewhere.
Another, less likely possibility, is that you may be having reduced absorption of iron from your body.
