Hi!
I don't have prostate cancer, but my daddy does. He has been coping since 2000. He used to get the worst hot flashes, I beleive it just comes with the territory of your entire body trying to fight off the cancer cells, so your body climate is pretty unstable. I dont think it is anything abnormal. My daddy just relaxes and takes deep breathes, tries to calm down and stand in front of a fan when he gets the flashes. I beleive he also takes some hormones to stabalize his body temperature.
Hope maybe I helped.
God bless, and best regards,
Kacey
