Yes, its totally possible. but i dont know the healing spell you are talking about but yes a spell can cure diseases and all illness, it depends on the power of the person casting the spell. but most people will say its not possible.

to add to the above posts, it depends on the spell and the illness. a candle spell probably would not cure cancer. it would probably help with the nausea. the stronger the illness, the stronger the spell you must cast. also, be sure the person you cast for is fine with magical help. some people don't believe or like magic for whatever reason, casting upon them because you think it's the right thing to do is imposing your will over them, so it can be considered 'black magic'.
