another con-radiation can have even more side effects later in life.
I have a suggestion, ask the dr if you do not do radiation now can be used if the cancer does return. can it be something in your back pocket for later? For instance, if you do radiation now, and the cancer comes back, can you do radiation again? wouldn't it be better to do a couple extra rounds of chemo. and hope it doesn't rtn...but, if it does, do radiation then? does that make sense?
The reason I suggest it, my son had a brain tumor, we chose a clinical trial, he did high dose chemo, and rec'vd stem cells...he went 5 yrs cancer free, when he relapsed he rec'd radiation. and that was 2 yrs ago. I know Wilm's is a whole different category...but, just a suggestion.
Radiation at his age usually doesn't change fertility as much as if he were older. so, there is a plus.
Good Luck. My sons dr.'s gave us plenty of advice and opinions....and they weren't always the same. I remember your post before-Is he at a Children's Hospital? I see you are in El Segundo-Mattel @ UCLA is great-so is CHLA. I don't know if they live local. Please, this is the 1st thing I tell newly diagnosed families-get treatment at a children's hospital. If you research success stories, statistically, you have better survivor rates from children's hospital's.
