I have no idea.
You can go back over 20 years, and there was not a known problem in the bloodline.
It's also hard to rule out environment. We never know what was put on our yards, and fields many years ago.
Neither parent developed cancer. So if its gentic, it started with that breeding.
They still don't consider the type of cancer Lucy had to be gentic, but couldn't 100% rule it out.
I didn't ask what type of cancer Kinzie had. When she was diagnosed, she was only given weeks to live. A small spot appeared on her ear. The same week, the lymph node on her neck become the size of a soft ball. I think they had 3 weeks with her. I didnt want to ask a lot of questions while they were grieving.
Not all those who wander are lost.
Life is just a leap of faith.
Spread your arms and hold your breath and always trust your cape.
Two things define you. Your patience when you have nothing, and your attitude when you have everything.
