Is this a good thing? My dad was due to have surgery in 4 weeks but they've done a biopsy this week to look for the PDL1 indicator and said if it's there then chemo and immunotherapy before surgery would possibly be the option with the best outcome. This would delay surgery for 3 months and he's worried if the chemo /immunotherapy doesn't work then the cancer will have spread in that time and then be inoperable.
