Suz47nascar,
I’m sorry to hear of your troubles! I was in a similar situation in 2009 after chemo caused septic shock, and then a domino effect of other life threatening conditions, including a collapsed lung, which put me in ICU for two months and hospital for six. It wasn’t until a year later that I had curative treatment.
I wish your mother a speedy recovery, so she may further treatment or hope the surgery was enough!
