Scientists have developed a vitamin D pill to treat advanced prostate cancer.
Exposure to Vitamin D from sunlight is known to improve the prognosis of certain cancers.

US drug company Novacea has produced a pill which delivers a concentrated dose of the vitamin without running the risk of side-effects from an overdose.

Chemistry and Industry magazine reports that if clinical trials of the drug - Asentar (DN-101) - are successful it could be available by 2009 //

Data shows that rates of prostate cancer are higher in countries further away from the equator, where there is less exposure to sunlight.
