Should you tell people you can cure diseases?

This question is a yes and a no.

For the yes , if you have the cure you can tell people and even before they have to know you have a cure to the disease, the medication or what ever it is must be first tested at the science laboratory. Before you tell people.

For the no, you might be telling lies and in case you mentioned what the cure for the disease is, one can mistakingly go out there to take some of the medication or what ever it is just to cure his or her disease and it can lead to so many crisis which can cause death

communicate with the patient and explain every step before proceeding to do so
