Hello! I have carefully & thoroughly evaluated what you have discussed. It appears that the pericarditis suffered by your husband is secondary to a malignancy, probably the colorectal cancer, hence there are many restrictions for his treatment. He will have no option than to have palliative care, & a psychosocial supporting therapy, if this is the case what I perceive from your description. Otherwise if the problem is not secondary to malignancy, then there is a lot more that can be done to completely relieve his symptoms, for example if it is due to tuberculosis, then a 100% cure is possible. Thanks & wishing a good recovery for your husband!
