Urmărește-ne pe DiscoverMai exact, la fiecare 15 ţigări fumate, are loc o mutaţie la nivelul ADN-ului, potrivit studiului realizat de Institutul Wellcome Trust Sanger din Marea Britanie.
Conform studiului, toate tipurile de cancer sunt provocate de erori la nivelul ADN-ului, mutaţii care pot fi induse de agenţi de mediu.
Niciuna dintre mutaţii nu pare să fie cauza principală a declanşării bolii, ci acţiunea lor combinată învinge, în timp, mecanismele de apărare şi de reparare ale organismului.
