So I attended my oncologist to get my CT Scan results immunotherapy appears to be working so I get #4 treatment tomorrow. The lung tumour has shrunk to almost half the size lymph nodes also shrinking so if treatment continues to work I can carry on with it for the next 2 years. Thanks pembrolizumab. I am so so relieved and staying positive. I am aware my cancer can't be cured but as long as this drug can keep it under control and I can have more years with family and friends.
