MIL has been dealing with cancer for several months. It doesn't look great and the treatment isn't working that well, but right now this is only 50% of her problem. If anyone's had the misfortune to deal with this - any advice on being treated decently by medical professionals???

Here's what she's run into so far:
- the doctor and the treatment center don't seem to communicate. The center staff misses important tests ordered by the doctor, then basically says "oops!" This is partly why we wasted three months on chemo that doesn't seem to have worked.
- when she comes to the center for treatment or a procedure, she'll come in on time and no matter what, be taken in last and leave last. Part of me wonders if someone's doing it on purpose, cause it can't be a coincidence every time. She's in her 80s, already not feeling great between her age and cancer, and they just keep her chilling in the waiting room. Some of the procedures are fasting. She's diabetic.
- of course, she eventually decided to go for a second opinion and possibly switch doctors. OMG, even worse. She was supposed to have a consultation today before a biopsy. The office handling that wouldn't tell her until the very last minute what time the appointment is set. Last night they called and asked her to show up *9:30 am* or all the procedures that follow are cancelled, because they depend on this consult. She's not young enough or well enough at this point to just hop on a train. It's a miracle she was able to arrange transportation at the last minute. Well, she comes in, the doc takes one look at her, cancels the consult and... sends her to the ER because she has really high blood pressure. Duh. She has really high blood pressure because his office kept her on edge all day yesterday. She was so stressed she was up half the night. Now the consult is cancelled, the procedures afterwards presumably aren't happening, and all that happened was that a sick elderly woman got dragged across town twice for nothing, and is spending the night at the ER.

She's sick of this mess, exhausted, and thisclose to giving up and just stopping treatment. It's not even like she's doing this alone. Her sons come with her to every appointment and try to advocate for her, but the system is too big and it doesn't care if one old lady lives or not.

Are we missing something? Is there any way to go through treatment while being treated like a human being? Any tips or tricks?
