That's the point - there is no tumour to remove. Cancer had been ruled out as a cause.

A good job, because he'd be dead by now otherwise. Such hormone-secreting tumours tend to grow fast, are terribly malignant, and all medical science can do is give a few months extra. Or weeks.

I had more MRI scans, Ultrasounds, blood tests etc than you can imagine, trying to find neoplasms. But there were none.
