Brooklyn, congratulations on the good scans. It's always good to hear there's nothing new and nothing bigger. I hope you continue to do well on Kadcyla. Texasrose, I don't think my 1st infusion was larger, but it did last longer because they had to give the infusion more slowly and watch me for reactions.
RNG is a game term that is an acronym for random number generator. Random number generators (or, more correctly, pseudorandom number generators) are algorithms used in computing when an outcome needs to be as random as possible. A computer can't generate completely random numbers on its own, so it uses a complex algorithm designed to get as close to random as is practical.
When there are a set of rules in place that cannot be deviated from, there is in actuality no randomness whatsoever. The term RNG is misused in this instance. The acceptable term is wonkey. This is such a stupid nitpick.
