Dr. Li Man
Colorectal cancer can typically cause iron deficiency anemia. It is a major cause of anemia. Gastrointestinal bleeding and blood loss due to colorectal cancer can significantly reduce hemoglobin levels in the blood. Colorectal cancer may also lead to inadequate absorption of nutrients such as folic acid and vitamin B12. Anemia associated with colorectal cancer might also result from its treatment.
