Hi, My Wife Came From A Hospital Visit Where They

Hi, my wife came from a hospital visit where they did an xray of the whole body and said they found a dark spot on the liver but did not explain anything. They said to continue with tests in another 6 months to see if it changed after having taken a new pill against HIV (from 3 to 2 to 1 (say that this is the best cocktail of today)).
I know that this is guesswork and I will talk to the hospital people next time more thoroughly but I want to be better prepared.
