Lots of people make a decision about not having children without cancer to prompt a response. I wasn't having any! I did change my mind, not because my later partner wanted children but because two of us bringing up a child became a very real want for me too. You may have to make this decision solo, so talk to your medical team so you are sure of the pros and cons. Whatever you decide, if you choose wisely for whatever matters to you, you'll have no regrets. I am confident that if I had chosen not to have children, I would be happy with that. That other path would not have been chosen, would have remained unknown so not a part of me. It's been a wonderful path, but then the other may have been too. Even if we live to 95, life's too short for deep regrets! Best wishes.
