Cancer
Many forms of cancer would lead to damages to your bone marrow in which blood cells are produced. As a result, it leads to a reduction of both white and red blood cells and causes leukopenia. In addition, many drugs and medications used for treating cancer can also further the effects and worsen the symptom. That’s why patients with cancer often experience extreme fatigue and can be more vulnerable to many diseases due to a weakened immune system. Radiation therapy, chemotherapy, and bone marrow transplant can be the main cause during cancer treatment. [6]
