Asymptomatic

Overview
In medicine, a disease is asymptomatic while the patient does not experience any noticeable symptoms. Asymptomatic diseases may not be discovered until the patient undergoes medical tests (X-rays or other investigations). Some diseases remain asymptomatic for a remarkably long time, including some forms of cancer. If a patient is asymptomatic, precautionary steps must be taken.

A patient's individual genetic makeup may delay or prevent the onset of symptoms.
