腫瘤細胞的DNA會從血液中分離脫落而成“循環中的遊離DNA”，而它可被用於識別導致不同類型的癌症的EGFR基因的突變狀況。

Experts believe the findings could aid future research by overcoming the difficulty of accessing some tumour samples.
The researchers analysed blood samples from patients with advanced non-small-cell lung cancer and looked for ‘circulating free DNA’ – bits of DNA shed from tumour cells that can be isolated from the blood.
They found that the tumour DNA present in blood samples could be used to identify different types of tumour-causing genetic faults in a gene called EGFR.
Blood samples could offer an alternative to tumour biopsies in lung cancer patients, according to European researchers.
