A prevention or preventative measure is a method to avoid an injury, illness, or illness to start with, and often it won’t help someone that is unwell. As an example, many babies in developed states are given a polio vaccination straight after they’re born, which stops them from contracting polio. But the vaccination doesn’t work on patients who have already got polio. Treatment or cure is applied after a medical problem has started.

Treatment treats a difficulty, and may lead the way on to its cure, but treatments frequently ameliorate a difficulty just for so long as the treatment is continued, particularly in protracted illnesses. As an example, there isn’t any cure for aids but treatments are available to decelerate the harm done by HIV and delay the death of the illness. Treatments don’t always work. For instance, chemical treatment is therapy for some sorts of cancer. In a number of cases, chemical treatment may lead to a cure, although not in all cases for all cancers. When nothing can be done to stop or improve a health problem, beyond attempts to make the patient more relaxed, the condition is claimed to be untreatable. Some untreatable conditions naturally resolve all alone ; others don’t.

Cures are a subset of treatments that reverse diseases utterly or end medical issues forever. Many diseases that can not be cured are still treatable.
