I doubt that the Dr. would object to you recording the meeting if the intent
is to use the recording as a "notepad" and ask him beforehand and offer to
provide him with a copy of the tape or the opportunity to review and revise
it before you leave. If the Dr. feels that you're setting him up with a
"well, you said this or you said that",  he will probably be reluctant to
having his every word recorded.
I use a recorder daily at work for notes, however, at meetings, I've found
that keeping written notes makes everyone more comfortable, if he/she speaks
too fast for your note keeping; ask him/her to slow down or repeat.

Doctors know, or should, that you are experiencing a shocking conversation
and will not remember most of what was discussed unless you record the
meeting in some fashion, I still think that written notes are preferable.

It would be helpful for you to write down any questions you may have, prior
to the meeting. Also write down any questions that may surface after your
meeting and ask those by phone or at your next visit.

I can't speak for everyone, but, I and many others never heard much more
than the word "cancer" at the initial meeting.
