Live Science: Older children often think younger siblings are a headache, but sobering findings reveal the chances of a child developing a brain tumor and cancer elsewhere in the nervous system increase with the more younger brothers and sisters one has.

infectious agents might play a role in causing these cancers.

The researchers analyzed more than 13,000 cases of nervous system tumors in Sweden, data collected over the course of more than 70 years. They found people with four or more siblings were twice as likely to develop such tumors as people with no siblings.

The investigators also found there was a two- to four-fold increase in nervous system tumor rates among children younger than 15 who had three or more younger siblings compared to children of the same age who had no younger siblings.

FYI -- You may want to add an attribution on this entry of yours re: the photo of the 3 kids.

Appreciate that a photo from my blog was used on your site...but it's not attributed to the correct photographer/link source. And it's not actually my photo, in the first place.

If you go back to my original post that you copied it from, you'd see a link via Flickr to the original source. Might be worth putting that on your post...

Otherwise, best to you in the research you're doing.
