Yes it can be completely normal to have a shorter treatment than first thought. If they go aggressively like it looks like they did with your mum. It can actually achieve what they where aiming to do. Only in a quicker time frame. When a oncologist says we will give you this ??????? For X amount of time. Please bare in mind it's not a exact science. It's worked out on average time scales. However in a lot of cases it could work out with some people to be a lot longer than first anticipated other times it can be one hell of a lot quicker than estimated. I take it after all that. She has had a scan and discussed the scan with your mum if I gave you a for instance maybe it may help more. After being diagnosed with stage 3B none small cell lung cancer. I had a operation to havd a left upper lobe removed I had 4 rounds of ajuvent chemotherapy. Which made me ill but bearable. 9 months later after having had 2 previouse scans every 3 months things where looking ok. On the third scan 9 months later I was told I was terminal with 6/8 months if I had some palliative treatment I would not get no where near that if I had not have had palliative treatment. After the first one a different drug I had 6 sessions booked originally. Second session as the first knocked me off my feet a few days I was sort of ready for it to happen again, so I had the second one. Sure enough it knocked me clean of my feet only this time it wasn't just for a few dats. The side affects were far worse the second time round. So so much worse I kept drifting in and out of consciousness. My Macmillan called our GP out. After her examination of me they took my husband out of the room but left a door open they where speaking quietly and said to him I am sorry but I honestly do not think your wife as very long left at all, they said well if you can squeeze a Christmas in before the weekend maybe I might just get to see it but by the weekend they said sorry she's going to actually be lucky to see the weekend we give her that at the latest. So when I said about squeezing in a Christmas I sort of meant like tomorrow or Thursday. We will only have Pallitive nurses in now from Thursday afternoon my Macmillan nurse she was a Pallitive nurse her self but if she could get out every timr to see me it would.be other palliative nurses not distract ones is what f sad he meant. The doctor left and I heard Diana my nurse say we will chat downstairs. Now how daft is this you hear them talking about you dying but all I could really think was I need a cup of coffee I shouted the best I could to my husband to make me a coffee if he didn't mind. What I didn't hear was my GP had ordered a hospital bed oxygen all to be delivered thst same day. Cutting a long story short because trust me I remember a lot. Apart from when I drifted away and sometime during the night I had been illusionsting overnight. I got it into my head I am not going to die this weekend no matter what anyone said. I am not ready so they can go to hell. I had lost my voice and my mouth and face was full of ulcers. In my mouth was horrendous. Oh no way could I actually get out of bed. I didn't die as I said I wasn't going to. However I pulled out of that chemo. I thought I might not have long but I am not spending it like that. Apparently I shocked them all by not dying. I whispered to my oncologist no more he couldn't hear me it was such a faint whisper. So my husband said she telling you she's not having anymore sessions of that chemo it almost killed her. He looked at me because at the end of the day I had to confirm what my husband said with my lost voice so he asked me to which I nodded to no more and almost croaked it out I had to have another scan and he arranged it plus another appointment all very quickly once I said no more. On my return I was better able to walk and better able to whisper. Ps my hair had gone too. My results shocked him, the drug that I had only worked on 6% of the population and surprisingly it had killed a lot of the cancer off. It was put down as a partial response. Which as I say it was the percentages of people it actually worked on plus the actual amount of cancer it had killed that was the shocking part. So this woman who was given 6/8 months left what cancer had survived my own body killed it. Not quite cancer free, but almost it stopped like that for 2 and a half years when it did start growing aha I went into immunotherapy pulled out after 7 months at present my cancer is stable after having given so much blood to cancers research to send to various countries to find out why I am still alive and they only thing they can agree on is I should be dead. But her I am 7 and a half years later. Still not needing anymore treatments.....so as I say cancer is not a exact science I hope this gives you some hope for your mum. We all react differently plus I am being honest once I was told I had cancer not even until they said terminal. I turned round I didn't cry I didn't say why my. I said oh no no no I have things to do places to go people to see so I am not going to die it's inconvenient. If you think I am going to let cancer take me that easy your very much mistaken, it's got a biggest fight ever it's got into the wrong body if it thinks it's taking me that quick hell will freeze over before that happens it's now thought my way of thinking and staying positive may have more to do with me being alive today than anything because after extensive bloods research etc they can not still

ans why I am still around and living. Without being crude I know it's going to catch up with me eventually and bite me on the ***. I meant bottom and get me. It might just be starting too we will see. If it is I can definitely not complain with how much longer I have had. Yet still not going without a fight. Lots of love and don't hesitate to ask me anything. Good luck to your mum. Take care Marj 

Wow that's truly incredible! I also believe in a positive mindset. My mum is very positive. She also has stage 3b non-small cell lung cancer. However her cancer is inoperable. The doctors seem really positive. One of the consultants said that 10-15 years ago this would have been bad news but survival rates have improved greatly. Also the oncologist said that they're aiming to cure my mum's cancer. I hope that they well. She's in very good hands. The hospital where she's being treated is fantastic. I hope that the immunotherapy keeps the cancer away for good. 

I wish you many long and healthy years.
