I am having a thermoregulatoru sweat test done because i don't sweat and have hypotension. can this detect cancer if i fail and no sweating happens?

No: You are having this test because you have an autonomic nervous system dysfunction. This is not associated with cancer. Having low blood pressure can be helped by eating 6 small meals a day and doing exercise while lying done. The core program by a physical therapist is very helpful. Be sure to check 25-oh vit d and restore to normal levels. Use unprocessed salt on your food , avoid alcohol.

No: You may have postural tachycardia syndrome. It causes your blood pressure to fall and your heart rate to increase for no clear reason. No one knows what causes it, but it is related to your nerves, blood vessels, and your hormones. Cancer is not a known cause of this, so you can take a breath and have one less thing to worry about! the picture shows systems affected by this fyi.
