I have had 4 operation in 3 yrs, my first was a complete hysterectomy because of cancer. I always went back to work after each operation and never really fully recovered from each when going back to work. Well now, I feel like I have dementia, I m lost with simply words when speaking, and I get panic attack also. Is this normal? Is my body still in recovery. I am 53 yrs old. .......P.S. I had adenocarcinoma cancer. thank you for your response.
