Hi there,
Of course much depends on your Mum, her attitude, her overall health, and how she wishes to proceed. Like your Mum, I'm old too. And after helping my husband through his chemotherapy for colon cancer, if I were in her shoes, I'd take the chemotherapy WITHOUT HESITATION. Sure like me, she's a bit older, but she's also of the generation (like me) who has witnessed the nasty side effects MUCH OLDER chemotherapy regimens.
But chemotherapy is no longer the blunt instrument it used to be. It is tolerable for most people.
Case in point -- my husband, who is Stage IV, is now wrapping up his first four months of chemo (Avastin, Oxyplatian and oral Xeloda). Since starting his chemo in April, he's done very well ... that is, once he got used to how he felt and learned to anticipate the peaks and valleys. Once he got to know the peaks and valleys of his therapy (i.e., he's typically drained for a few days after the chemo then he picks up to almost normal) he's been able to return to near normal daily activities like fixing his car, returning to work on light duty, puttering around his workshop, etc. And he's a supposidly incurrable Stage IV who was supposed to die about now if we had listened to the doctors. Hardly, he's gaining weight and is currently NED with a very low CEA rate.
More importantly, he's not Stage IIIb (like your Mum) which is considered curable. Moreover, given that 30% of Stage IV patients diagnosed today can expect to live beyond five years, it means if your Mum is up to it, meaning she wants to fight her cancer and do what needs to be done and take the chemo given to her, then she's got much higher odds than my husband -- who, by the way, is currently doing well and now entering his first chemo brake after his next drip and planning a couple of short trips to see friends and family in celebration.
Finally, each person undergoing cancer treatments are different. Much depends upon one's "can do it, can win this battle" attitude. If your Mum's heart is not into the battle (my father at age 72 gave up and died from another disease) there is not much you can do about it.
But, on the other hand, perhaps you can share with her the survivor stories on this and other message boards, and help convince her that chemotherapy is not as bad as she likely thinks it is. Sure, any chemo is not a cake walk -- my husband will be the first to admit that, as I'm sure other survivors will tell you -- but neither it is abject torture either. There are ways and methods to help patients with chemotherapy and its side effects. Also, there is everyone on this board who can offer what they have learned. Indeed, I must thank the fellow who suggested in an earlier post on about how to mitigate neuropathy. Thanks to his post, we implemented his suggestions very early on in my husband's chemo journey - and we've since implemented more -- and as such, his hand/foot/mouth issues have been tolerable for the first week after his drip, then in the second week, nearly non-existant to the point that he eats ice cream. So, please ask your Mum to reconsider ... describe to her these posts and even print them off and share them with her ... and then encourage her. If after you have informed her fully -- been an advocate in finding the right advice -- and she still declines to fight her battle against her cancer, you must respect her wishes ... just as many years ago, I had to respect my Dad's wishes.
