Hello and welcome to BBC Xtra English!

Scientists have unlocked the entire genetic code of two of the most common cancers - skin and lung - a move they say could revolutionise cancer care.

Not only will the cancer maps pave the way for blood tests to spot tumours far earlier, they will also yield new drug targets, says the Wellcome Trust team.

Scientists around the globe are now working to catalogue all the genes that go wrong in many types of human cancer.

The UK is looking at breast cancer, Japan at liver and India at mouth.

China is studying stomach cancer, and the US is looking at cancers of the brain, ovary and pancreas.

Professor Michael Stratton from the Wellcome Trust told the BBC that “ These catalogues are going to change the way we think about individual cancers ”.

The International Cancer Genome Consortium scientists from the 10 countries involved say it will take them at least five years and many hundreds of thousands of dollars to complete this huge task.

But once they have done this, patients will reap the benefits.

Professor Michael Stratton, who is the UK lead, said: "These catalogues are going to change the way we think about individual cancers.

"By identifying all the cancer genes we will be able to develop new drugs that target the specific mutated genes and work out which patients will benefit from these novel treatments.

"We can envisage a time when following the removal of a cancer cataloguing it will become routine."

It could even be possible to develop blood tests for healthy adults that can check for tell-tale DNA patterns suggestive of cancer.

Cancer experts have applauded the work.

The Institute of Cancer Research said: "This is the first time that a complete cancer genome has been sequenced and similar insights into other cancer genomes are likely to follow.

"As more cancer genomes are revealed by this technique, we will gain a greater understanding of how cancer is caused and develops, improving our ability to prevent, treat and cure cancer."

Professor Carlos Caldas, from Cancer Research UK's Cambridge Research Institute called the research "groundbreaking".

He feels that the study is groundbreaking because for the first time researchers have been able to link particular mutations to their cause.

It is so exciting that he feels in the future scientists can have a "detailed picture of how different cancers develop, and ultimately how better to treat and prevent them."
