Could you have cold sweats after having snyope experiences with injuries? and could any type cancer cause these?

Syncope vs. cancer: If you sustained an injury and ended up passing out (syncope) from it, you may expect having cold sweats from the syncope. I am not sure what cancer has to do with the injury, though, unless you may have cancer that caused you to pass out and sustain the injury in question, but the cold sweats are still related to the syncope and not to the cancer.
