Patterns in the DNA of cancers would be able to show if smoking caused the disease in a patient

Scientists claim to have found clues about the causes of cancer which they say could lead to personalisation of treatments for the disease.

After analysing tumours of 12,000 NHS patients, researchers said that it was possible for the first time to detect patterns – called mutational signatures – in the DNA of cancers.

These patterns serve as clues including whether a patient has had past exposure to contributing factors such as smoking or UV light.
