Unfortunately, you really have to be sceptical about the treatments doctors suggest.
In the complicated German health care system, accounting regulations for hospitals change from time to time.
Depending on how the current regulations about remunerations are, hospitals change their behavior, e.g. wherease some years ago patients had to stay in hospital for two weeks after small surgeries or treatments, now they are thrown out of the hospital bed when the bleeding has hardly stopped - reason is, hospitals used to get 'credit points' for each day a patient was in hospital, and how they get the credit points for each operation performed, so there interest is to get rid of the patients as early as possible.
Due to the new regulations, many hospitals propose surgery much too early although conservative treatments would be promising.
It's a scandal.
