Cukrzyca i otyłość są związane ze zwiększonym występowaniem nowotworów złośliwych w różnych lokalizacjach. Metformina jest powszechnie stosowana u chorych z cukrzycą typu 2, zwłaszcza u osób otyłych. Wykazano, że obniża ona zarówno zachorowalność na nowotwory złośliwe, jak i umieralność z ich powodu. Mechanizm działania metforminy jest plejotropowy: aktywuje szlak LKB1/AMP (kinaza wątrobowa B1/adenozynomonofosforan), prowadząc do hamowania szlaku mTOR, hamuje podziały komórkowe również poprzez wpływ na cykliny, promuje apoptozę i autofagię komórek, hamuje aktywność metaloproteinaz i aktywuje układ immunologiczny. Metformina obniża zachorowalność na raka płuca, trzustki, wątroby i jelita grubego. Zmniejsza odsetek trójnegatywnych raków piersi oraz poprawia odpowiedź na neoadiuwantową chemioterapię w przypadku tego nowotworu. W raku endometrium potęguje działanie gestagenów, potencjalizuje wpływ paklitakselu i poprawia odsetek przeżyć. W przypadku raka szyjki macicy wydłuża czas do wznowy, a przy raku jajnika wydłuża czas do progresji oraz poprawia całkowity czas przeżycia. Badania wskazują, że jednym z dodatkowych mechanizmów działania metforminy może być jej destrukcyjny wpływ na komórki macierzyste raka.

Diabetes and obesity are associated with an augmented manifestation of malignant tumors of various localizations. Metformin is commonly used in patients with diabetes type 2, particularly those classed as obese. It has been shown to reduce both incidence of malignant tumors and respective mortality. The action of metformin involves a pleiotropic mechanism: it activates the LKB1/AMP pathway (liver kinase B1/adenosine monophosphate) which inhibits the mTOR pathway and blocks cell division also by its effect on cyclins. Additionally, metformin promotes apoptosis and cellular autophagy, inhibits the activity of metalloproteinases and activates the immune system. Metformin reduces the incidence of lung, pancreas, liver and large intestine cancers. It also reduces the percentage of triple-negative breast cancers and improves response to neoadjuvant chemotherapy in this disease. In endometrial cancer, metformin increases the positive influence of gestagens, potentiates the effects of paclitaxel and improves survival. In cervical cancer, metformin extends time to relapse, and in ovarian cancer, it extends time to progression and improves overall survival. Studies indicate that a destructive effect on cancer stem cells may be its additional mechanism of action.
