I'm having a really bad day today. My mum has stage 3b lung cancer and has just finished chemo and radiation. She will likely start immunotherapy soon. The oncologist was really positive and said that they're aiming to cure her cancer and that immunotherapy boosts survival. However she's seen people being cured of the same cancer without immunotherapy.

Today I've been reading online and have made myself even more anxious. There's so much mixed information. Some sites say that stage 3 lung cancer can be cured, others say that it can't. There also seems to be quite a lot of hope with the immunotherapy.

I'm scared that the cancer will still come back with immunotherapy. I read that 90% of people without immunotherapy have the cancer come back with a year and that immunotherapy makes it come back 3 times the time of that, so it doesn't make it stay away forever. I don't know I'm really confused. The doctors seemed really positive about my mum. My mum is being treated at a very good hospital. 

I'm scared as 3-5 years survival is not good enough. The doctors haven't given us any time frame of how long my mum will have or how many years left. The oncologist said that using the best treatment and immunotherapy will help boost her 5 year survival rate but I know that statistics on cancer aren't usually done past the 5 year survival rate. Does this mean that my mum could have a lot longer?
