What are some early symptoms of leukemia?

The early signs and symptoms of leukemia include fever, persistent fatigue or weakness, frequent infections, weight loss, and easy bruising, states Mayo Clinic. These symptoms may persist for many weeks to months.

Leukemia is a type of cancer that affects a patient's blood-forming tissues, according to Mayo Clinic. The disease affects a patient's bone marrow and his lymphatic system, which can cause a variety of symptoms. Patients with leukemia tend to bruise or bleed easily, since their blood-forming tissues are being attacked by the cancerous cells. They also tend to get frequent infections, since their lymphatic system is breaking down and is closely tied into their immune systems.
