Kòm timè grandi, yo evolye. Apre yon tan, mitasyon goumen ADN nan, ak yon pati nan timè a kòmanse gade trè diferan nan yon lòt. Men, Swanton te jwenn ke selil timè menm konplèks ka sipòte l 'karakteristik yo nan orijin yo. Ekri nan jounal la, Syans, li dekri kijan, nan de pasyan kansè nan poumon, pwoteyin sifas te sibi mitasyon byen bonè nan e te parèt nan tout timè yo.

As tumours grow, they evolve. Over time, mutations scramble the DNA, and one part of the tumour starts to look very different to another. But Swanton found that even complex tumour cells can bear the hallmarks of their origins. Writing in the journal, Science, he describes how, in two lung cancer patients, surface proteins had mutated early on and appeared throughout the tumours.
