Cauza cancerului la colon a fost identificată de cercetători în bacteria care provoacă apariţia diareei la copii şi adulţi şi care poate duce la inflamarea colonului şi apariţia unor tumori maligne, potrivit unui studiu publicat în Nature Medicine şi citat de sciencedaily.com.
Până la 35% dintre copii şi adulţi şi până la 40% dintre persoanele cu cancer la colon sunt purtătoare ale acestei bacterii. Cercetătorii consideră că bacteria ar putea interacţiona cu altele din intestin, ducând astfel la apariţia cancerului la colon. Descoperirea este considerată de o importanţă similară cu cea a identificării cauzei ulcerului stomacal - bacteria Helicobacter pylori, suspectată că ar fi responsabilă şi de majoritatea formelor de cancer la stomac.
