Deprivation has a serious impact on cancer survival rates, a Welsh study shows.
There is a 6% gap in one-year survival rates for men diagnosed with cancer between those living in Aneurin Bevan Health Board area and those in rural Powys the least deprived area of Wales.
Five-year survival rates for men and for women are also lower in Aneurin Bevan Health Board, which includes the deprived areas of Blaenau Gwent, Torfaen and Newport, than elsewhere in Wales.
The data, published in a series of maps, also reveals a north-south divide in cases of lung cancer the deadly disease is the second most common form of cancer for men and women living in South Wales but the third most common for people in Mid, West and North Wales.
Neighbouring Cardiff and Vale University Health Board has some of the highest one and five-year cancer survival rates for men and women in Wales, Madeleine Brindley wrote in Western Mail.
Dr John Steward, director of WCISU, said that a number of factors might account for the variation in survival rates, including the general health and nutrition of the population; awareness of cancer symptoms and access to and the response of local GPs; access to hospital and specialist care and screening for cancer.
All of these may be determined by underlying deprivation and previous research has suggested deprivation is a major contributing factor to cancer.
