My husband was diagnosed with plural mesothelioma last June. He has never knowingly worked with asbestos but has enjoyed renovating houses over the years and we think this must have been where he came in contact. He has had 6 rounds of chemo which he came through fairly well although it was quite brutal. His scan in February showed no disease progression but the last one shows a deterioration. He has been offered an immunotherapy trial and although we are keen to try immunotherapy are concerned about the possibility of him getting the placebo. We have going private to ensure he gets the drugs and wondered if anyone out there has experience of immunotherapy to see if we should pursue this. Any advice would be helpful.
