Oh Boyd, I am sending prayers for your entire family, how very scary this is!! My cousin went through it a couple of years ago. I believe hers was diagnosed as Non Hodgkins Lymphoma.
She was devastated as she had waited years to get her life where she wanted it and they had finally decided to try to have a child. She had already been warned she may not be able to get pregnant due to other health issues and if she did, she would need to take blood thinners through due to blood clotting disorder.
Well, she beat the cancer, waited a year after the chemo and radiation like they told her too, then they went off birth control and low and behold she got pregnant the first month!! She gave birth to a beautiful healthy baby boy nine months later!! He is now 2 and they are thinking about #2!
Why did I tell you all this? This is a very beatable cancer, happy endings are in your future!!
