Putting aside that MDs trained in medical ethics should be the ones to decide the end-all debate of HRT for those under 18y/o (or maybe 24 by your standard) -- I would imagine "tips" here is mostly about logistics of navigating the US health system and filling in health-effect anecdotes where science has yet to affirm/study (which encompasses more areas of health than you might think). Also, "Invasive" and "non-invasive" are usually reserved for surgical contexts so I'm not sure I would apply that here.
