Why is early detection for leukemia difficult?

Early detection of leukemia is challenging because its symptoms often resemble those of common illnesses, such as fatigue, fever, and frequent infections, leading to potential misdiagnosis. Additionally, the disease can progress rapidly and may not present noticeable signs in its initial stages. Diagnostic tests, such as blood tests and bone marrow biopsies, are necessary for a definitive diagnosis, but these are not routinely performed unless there are compelling reasons to suspect leukemia. As a result, many cases are identified only after the disease has advanced.
