For example, there is evidence for metformin preventing the growth of cancer cells in lung, prostate, colon, and genograph. Since 2005, metformin has been reported to reduce the risk of cancer by up to 23% worldwide.
The anticancer activity of metformin has been confirmed against several cancer types in vitro and in vivo. However, the underlying mechanisms of metformin in the treatment of cancer are not fully understood.
Altogether, 12 randomized controlled trials and 41 observational studies met the inclusion criteria. They noted that in observational studies there was a significant association of exposure to metformin with the risk of cancer death, all malignancies, liver, colorectal, pancreas, stomach, and esophagus.
The current proposed anticancer molecular action of metformin is mainly associated with the inhibition of the mammalian target of rapamycin complex 1 (mTORC1). The mTOR pathway plays a pivotal role in metabolism, growth and proliferation of cancer cell (12). Metformin is thought to inhibit mTORC1 pathway (Figure 1).
1. Metformin action. Metformin protects heart and pancreatic β cells in addition to its improved insulin sensitivity in the primary insulin-targeted organs, such as liver, fat and muscle.
For decades we've known that metformin does more than just help lower blood sugar in people with diabetes. It also offers them cardiovascular benefits, including lower rates of death due to cardiovascular disease. And it sometimes helps people with diabetes lose excess weight.
Moreover, metformin improves insulin sensitivity and decreases fasting insulin levels in cognitive impairment patients with abnormal glucose metabolism (31). Metformin is a rational treatment choice for pregnant women with T2D, gestational diabetes (GDM), and polycystic ovarian syndrome (PCOS).
The study examined nearly 7000 people with a diagnosis of skin cancer (basal cell carcinoma or squamous cell carcinoma) and nearly 70,000 others. The authors discovered that: people taking metformin, even at very low doses, were about 30% less likely to develop basal cell carcinoma.
Our results indicate that metformin is associated with an estimated reduction of 62% in the risk of liver cancer among patients with type 2 diabetes. When restricting the analysis to four studies that investigated HCC, metformin is associated with an estimated 70% reduction in the risk of HCC.
Metformin suppresses the growth of colorectal cancer by targeting INHBA to inhibit TGF-β/PI3K/AKT signaling transduction.
For People With Diabetes, Metformin Lowers the Risk of Death
Research in humans suggests that metformin can impact mortality. A meta-analysis published in 2017 that included 53 different studies concluded that metformin reduces all-cause mortality and diseases of aging, independent of its effect on diabetes.
The current drug labeling strongly recommends against metformin use in some patients whose kidneys do not work normally because use of metformin in these patients can increase the risk of developing a serious and potentially deadly condition called lactic acidosis, in which too much lactic acid builds up in the blood.
Metformin-induced AMPK activation has also been shown to reduce cancer cell proliferation through several other mechanisms, including activation of cMYC, HIF-1α and DICER1 [11]. However, an alternative hypothesis focussed on metformin's effects on systemic 'host' metabolism has been proposed.
In a large six-year study, Professor Samaras and team previously found that people with type 2 diabetes taking metformin showed much slower cognitive decline and had reduced rates of dementia development, compared to those not taking the drug.
Metformin is considered a safe, cheap and effective medication worldwide, but it can cause some minor side effects in some people. Many of these mild symptoms are associated with taking the medicine for the first time.
Metformin doesn't cause kidney damage. The kidneys process and clear the medication out of your system through your urine. If your kidneys don't function properly, there's concern that metformin can build up in your system and cause a condition called lactic acidosis.

Six included studies were evaluated for the relationship between metformin and TC in NAFLD patients. It was revealed that metformin can significantly improve the high level of TC in NAFLD patients (MD = −0.29, 95% CI = −0.47 to −0.10, P = .
Metformin inhibits the growth and migration of thyroid cancer cells directly by mechanisms related to AMPK and mitochondrial respiration, and indirectly through effects on TSH levels and metabolic parameters associated with a less favorable environment for cell proliferation, as well as potentiating the effect of ...
Metformin also has anti-inflammatory effects, which may contribute to its ability to slow aging. Since chronic inflammation is one hallmark of aging and age-related diseases, reducing inflammation can improve health and life span. “It takes an old cell or an old organ and fixes a lot of things.
It's one of the most effective, safe, and commonly used medications for lowering blood sugar. Metformin isn't currently recommended for anti-aging benefits, and more research is needed.
Specifically for aging, metformin leads to decreased insulin levels, decreased IGF-1 signaling (Liu et al., 2011), inhibition of mTOR (Kickstein et al., 2010; Nair et al., 2014; Pérez-Revuelta et al., 2014), inhibition of mitochondrial complex 1 in the electron transport chain and reduction of endogenous production of ...
Outside of their work, other scientists are hailing metformin as a wonder drug not only because of its effect on Type 2 diabetes, but because of its emerging prominence in cancer research and potential influence in the lungs of those diagnosed with tuberculosis.
The use of metformin by non-diabetics stems from some evidence that metformin can decrease inflammation, protect against cardiovascular disease and cognitive impairment, minimize cancer risk and progression, and prolong life.
The drug may help with weight loss, inflammation, heart disease, and more.
