Husband diagnosed with Colon Cancer treatment was surgery then offered but not advised to have Chemo as they believed they had got all the cancer, no lymph nodes impacted and chemo considered to have very marginal potential benefits. No further treatment. 6 months later received the news it's spread to duodenum. They won't operate as they are not sure that will kill/get all the cancer and very risky operation. Question is what are the other treatment options we should explore?
