My bro has been on sutent and is moving onto immunotherapy soon so currently not medicated. Has 1 functioning kidney and a vertebral implant but otherwise just a regular 40y/o meatsack with cancer that is "under control". Any concerns we should have regarding vasoconstriction and blood pressure or kidney issues?

Will obviously talk to a doctor about it but any info anecdotal or otherwise is helpful thx.

Edit: did some research, talked to some docs, psychs and weed have been known to reduce efficacy of immunotherapy, as these drugs are immunomodulatory. So we are holding off. If he comes off these meds we will reassess. Thought this was important to mention.
