Hello, here are the basics

Cancer patient, lumber puncture was performed after speach became slurred and swallowing mechanism not working properly. MRI and CAT scans were performed to rule out the cancer having spread to the brain or a mild stroke, neither of which had occurred. The results showed high levels of protein, any ideas as to why?

Still waiting for an appointment with neurologist about what might be the cause.

Cheers

Elevated protein is a non-specific indicator of disease, ie meningitis, encephalitis, inflammatory diseases OR of tumor.  
Where is the primary tumor site?

The primary tumor was is the kidney which was removed in November last year.

Not a real good cure rate for that.  And it can metastasize to almost anywhere in the body.  However, my ex husband had cancer of the kidney and had his removed about 15 years ago without a recurrence.  Had one bad scare with a swollen lymph node in his armpit, and we later found out that it was cat scratch fever.  His cancer was at a very early stage when they found it.  I think he went in for a GI problem and they did a routine urinalysis and the blood in the urine led to his diagnosis.

so elevated protein level means that there is increase in plasma colloid osmotic pressure and hence decrease in GFR and this means thats there is very low urine formation in cancer guide me through it.
