Researchers from Britain have made a landmark discovery wherein they were able to do the genetic mapping of two widespread cancer forms. The mapping has unravelled the DNA mutations that cause cancers inflicting the skin and the lung, the finding of which could alter the manner of diagnosis and treatment of these ailments in the imminent future. Cancers are the consequence of the harm done to the genes i.e., mutations in DNA which are elicited by factors that are environment-related like tobacco, exposure to detrimental chemicals or ultraviolet radiations that leads to the cells growing uncontrollably. Researchers at the Wellcome Trust Sanger Institute, Britain along with their associates have be able to map this genetic harm from the tumours of 2 patients ailing from lung cancer and  [...]
