general retinoblastoma questions

since this was a discussed topic the other day, what is the avg. age a child is diagnosed?  would the white reflex be consistently showing up in photos?  what are the odds of a child getting this form of cancer?  i have searched the 'net, but trust the info. here on this board since i know the sources are reliable.  thanks.

1. I don't know. You would have to look that up. I would surmise between age 6 and 18 months.
2. No the retinoblastoma may be of a size or location that it doesn't cause a white pupil reflex.
3. I don't know. an educated guess would be one in 25,000 births.

You can look up the exact figures. I'm rather busy today.
