My husband was diagnosed with bowel  cancer nearly 4 years ago . He had surgery to remove it the chemo .we hot the all clear fir 6 months when he went for his next check up unfortunately the cancer had spread to his liver.we were then told no surgery is available but luckily a few weeks before covid the surgeon contacted him and did the surgery. He then went 9 months with no chemo. The next scan showed his cancer was back . He's been having chemo for 6 months but it is no longer working. 

We received a letter to say he might be able to have immune treatment but we will have to wait 6 weeks with out any news he has now gone 14 weeks with out any chemo and still another 6 to wait .has anyone had any success with immune treatment. If not the oncologist  has said 6 months at the most
