MPs are to launch an inquiry into “postcode lotteries” in cancer treatment.

The all party parliamentary group on cancer will investigate why mortality rates are 15 per cent higher in some poor neighbourhoods than the national average.

It will also consider why people from some black and minority ethnic groups or who have certain disabilities are more likely to be misdiagnosed or receive poor treatment.

Group chair Ian Gibson said: “It is very worrying that in 2009 we still don’t know why inequalities in cancer treatment continue or how we can ensure that every cancer patient gets the same high quality treatment no matter who they are or where they live.

“We think an inquiry is vital if the government is to meet its stated goal of reducing cancer inequalities by 2012.”

The group is asking for people to submit written evidence by 25 June.

An inquiry report will be launched in December.
