Treatment modalities refer to various methods or approaches used in healthcare to diagnose, treat and manage a patient's condition. These may include medications, therapies, surgeries, or other interventions that are designed to improve the patient’s overall well-being. The choice of treatment modality depends on factors such as the severity of the illness, the patient’s medical history and their personal preferences. Treatment modalities may be used individually or in combination with one another depending on what is best for the patient's specific needs.
