I don't know your life story, but you probably don't know how an artist works and you probably don't know the power that art (especially music) has to heal people, but let's focus on your question.
An unhappy artist in a profession that doesn't make sense for him/her could be dangerous:
The person can be mentally affected because he/she works in a shitty job, that can lead to stress, depression, etc. And the last thing you want is to be treated/envolved/engaged by a depressed {put any profession here} doctor or to travel in an airplane with a burned out, stressed, depressed pilot.
The probability that something REALLY good and life changer can come out from an unhappy and unfulfilled person is really low, let alone the cure of cancer.
