Cancer treatment for Adrian

My husband Adrian was diagnosed with stage 4 Bowel cancer in July 2018 age 44 that’s the day our world came crashing down.
adrian has had chemotherapy since then and it worked its magic taking Adrian from not operable to operable this year in February however due to delays in the operation because of covid the cancer spread from 6 Mets in the liver to 20 Mets and is no longer operable, we are devastated and to make matters worse the chemotherapy is stopping working and we are running out of options, we have been told Adrian could stop treatment and enjoy what time he has left or there is a drug called avastin that could be given alongside chemo that could work, if Adrian received private care he would have received this drug as standard but as we nhs we have to self fund this for him, Adrians worked so hard all through his chemo to pay the bills barely having a day off ensuring his little family still get fed and now it’s my turn to look after him and give him time, time together it’s all we want.
