I Had A 2 Brain Surgeries. 1 At 13 For

I had a 2 brain surgeries. 1 at 13 for a tumor and the 2nd for scar tissue and the remaining portion of my right temporal lobe and hypo-campus. My seizures returned soon after due to the stress. Now 23 yrs later, I had a cyst on the same side of my brain. This caused my very serious seizures. My stress level working 24 hrs a day for yrs was a direct result of the occurrence of seizures. 3 weeks ago I had 2 more brain surgeries where a cyst was removed on the same side as the last. Is it possible the stress levels I endured for years may have caused the cyst to develop?
