A new online map that allows people to enter their postcode and find the risk of developing 14 conditions has gone live, highlighting the high risk of skin cancer in Cornwall and Devon.
The map created by researchers at Imperial College London presents population-wide health information for England and Wales, with the risk of malignant melanoma highest in Cornwall and Devon.
The data was gleaned from the Office for National Statistics and from cancer registries for 1985 to 2009.
The atlas provides maps of the geographical variations for a range of health conditions and environmental agents at a small-area scale (census wards). It also provides contextual information such as known risk factors for the health conditions and a summary of what is known about possible health effects associated with the environmental agents mapped in the atlas.
The data was also adjusted for age, deprivation and to take into account small numbers.
Also included are the relative risk levels for lung cancer, breast cancer, prostate cancer, bladder cancer, leukaemia, brain cancer, mesothelioma, liver cancer and coronary heart disease mortality.
Dr Anna Hansell, from the UK Small Area Health Statistics Unit told the BBC: "We tried to present this so people do not jump to the wrong conclusions."
"The new thing about it is you can go right down to neighbourhood level - beforehand it has been at a broader scale."
