Basal cell radiation

I hope not to offend anyone here as my problem is so small compared to many on this forum.

69 year old male stroke survivor with heart failure. Now diagnosed with basal cell on my nose.

I've recently had a consultation with a specialist regarding  surgery to remove the growth. I thought he was rude and slightly arrogant but respect his experience. However, it has made me question if I want to proceed with the operation given his somewhat glib attitude. Has anyone had experience of radiation treatment, if so I would really appreciate your feedback

Thanks and regards

Phil
