My mom was diagnoised in Sept. 07 with lung cancer. She had 42 treatments of radiation on her lungs which in turn burned her throat , she had 10 chemo treatments and then they did 24 radiation treatments on her brain. Everything seemed to be going fine but, now it seems that she has lost her memory, or even Alzheimer's has set in. The doctor's say this is normal but my poor dad is almost at his wits end with taking care of her, between her putting on three pairs of pants or going to the bathroom in the closet. Now every pain she gets, she is so hard to handle because she wants to go to the emergency room. Thank goodness my dad is retired military. Has anyone else experienced any of these side effects?
