While I think this was absolutely the right decision for this particular person, I am very glad my mother-in-law has decided to go with chemo and radiation and all the other treatments, even as the cancer has spread from her lungs through her body.
Our children were teens when she was first diagnosed. Thanks to chemo slowing the progress of her cancer and extending her life, she's been with us as they've grown into young adults.
And her doctors have done a GREAT job of ensuring her comfort and maintaining her quality of life. She is not miserable, she's happy. Her mind is as sharp as ever. She still has her hair (though it lost a bit of it's curl, temporarily). Chemo's come a long way in the last decade!
And it's been a privilege having her in our lives these past few years.
So while each person's decision is individual, I'm glad my mother-in-law has decided to live longer.
