Hi, dairy have gone through your question. I can understand your concern. Black out may occur due to anemia, hypoglycemia, hypotension, hypertension.  Chances of tumor causing blackout are very rare.  So first you should go for basic investigation for anemia, diabetes and hypertension.  Then you should take treatment according to cause. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
