Hi Hanky I've also got metastatic cervical cancer in my chest now and micro cancers in my system. I've been looking into immunotherapies as I'm at the beginning of this, but I thought the dentritic cell therapies and CAR-NK cell therapies looked promising but means travelling abroad... I'm putting my flat on the market this next few weeks to try to raise the capital, but please google these cell therapies. I believe the CAR-HK cell therapy costs around £80,000 but the dentritic cell therapy costs around £16,000 and can get done in the UK... Best wishes xxx
