A prognosis is a medical professional's prediction about the likely course and outcome of a disease or condition, including chances of recovery. Doctors base prognoses on factors like the type and stage of illness, the patient's overall health and age, available treatments, and statistical outcomes for similar cases. A prognosis might describe expected survival time, likelihood of full recovery, potential complications, or quality of life expectations. Prognoses are inherently uncertain since individuals vary, and medical advances can change outcomes. Understanding a prognosis helps patients and families make informed decisions about treatment options, care planning, and personal affairs.
