癌症在人類眾多殺手中名列前茅，每四個人之中就有一個人會患上癌症。不少早期癌症都沒有任何徵狀。當病人感到不適而求醫時，往往已是癌症晚期，大大降低生存機會。因此，不少科學家都致力研發早期癌症診斷方法，希望能及早診斷出癌症並提供治療，以挽救更多生命。傳統上我們依靠入侵性方法，如活組織檢查作癌症診斷。然而，這些入侵性方法可能導致痛楚、感染或誤傷附近的器官，不少人因而卻步。有見及此，科學界正努力研發各種無創癌症檢測方法，讓癌症檢測變得更安全。這新興領域稱為「液體活檢」…

Cancer is one of the leading causes of death. One in four people will suffer from cancer in their life time. Many cancers are asymptomatic in early stage. When patients are diagnosed with cancer, they are often in advanced stages, leading to a poorer survival. The key to conquer the disease is to detect cancer at its early stage. Traditionally, cancer diagnosis relies on invasive methods such as tissue biopsy, which can cause complications such as pain, infections and injuries to surrounding organs. As such, there has been an increasing interest in the development of non-invasive methods for cancer testing. This emerging field is called ‘liquid biopsy’…
