It is very sad for someone so young to die from cancer. I can't stand programs like Big Brother and was never a fan of Jade's but I feel some connection with her - I saw her once at McDonalds (when she was really nice to a couple of people who asked her for her autograph) and she got married in the village I grew up in.
Once girls are vaccinated the problem of cervical cancer should improve, here in the UK there is also a vaccination program
"From autumn 2008, the vaccine will be offered every year to 12- to 13-year-old girls (school year 8). A three-year catch-up programme will also start from autumn 2008 and will offer the vaccine to older girls aged 13-18."
However that leaves a huge number of girls unprotected, and in England they don't screen until you are 25 (in Scotland it is 20).
Jade has given some money to charity. Apparantly she donated money in India after she did Big Brother there to help the street kids.
