Welcome to Cancer Chat Sam although I'm sorry to read about your mother-in-law's diagnosis.

We have some general information about what to expect in the last few weeks and days which I hope will help you know what to look out for as the time draws near, but only her medical team can give you a timeframe so if you or your wife are able to get your mother-in-law's permission to speak with them privately you should be able to find this out.

Our members know how difficult this time can be so hopefully you'll get to hear about their experiences and get some advice from them soon.

Kind regards, 

Steph, Cancer Chat Moderator
