Hi Suzan - First, welcome to the site, sorry you had to find us. What good news you share with us today! Regarding liver regeneration, that is a good question for your surgeon. I also had a liver resection, but for some 'strange' reason, my liver did not regenerate back to capacity. it's just one more way I'm 'outside the box' with my CC journey, according to my doctors. But for only having 25% of my liver left, I'm doing OK.
I think I can speak for all of us who have had chemo, getting 'CHEMO BRAIN' is a very normal side effect. Some chemo drugs cause chemo brain worse than other drugs (at least in my experience, and I have been on several different chemo drugs in the 2 1/2 years since I started down this wacky crazy road). I still search for words sometimes but am better at forming a complete thought and verbalizing it. One thing I have learned to do is, the minute a thought pops into my head, write it down immediately. Otherwise, for me, the thought disappears as quickly as it came. I am always writing post it notes to myself like 'start dishwasher', or 'call so and so'. For a while it looked like (and still does sometimes) that I'm redecorating my home with post its! I also lose my train of thought frequently in the middle of sentence, so I just laugh and say 'oh well, that train left the station'. Sometimes the thought circles back around and sometimes it doesn't. Luckily my family and friends are sometimes able to help me reel the thought back in too. Keep asking questions, knowledge is power. Take care!
