    Does metformin cause cancer


    Metformin is the most commonly prescribed treatment for type 2 diabetes and has consistently shown anti-cancer benefits in research studies. Metformin has modest effects on blood glucose levels but helps to reduce the amount of insulin produced by the body and therefore has wider benefits including reducing cancer risk. Metformin helps to improve sensitivity to insulin in the body and helps to reduce production of glucose by the liver (gluconeogenesis). These two mechanisms can both help to reduce the amount of insulin the body needs to produce. Insulin is the hormone responsible for moving glucose out of the blood and into our cells. Insulin has another role and that is in helping new cells to grow. Cancer occurs when new cells grow in an uncontrolled fashion, resulting in a tumour. Population studies, mouse models, and mechanistic studies all show that metformin, a cheap well-tolerated diabetes drug, impacts in some way on how some cancers develop and progress. Anna Wagstaff talks to clinicians and researchers building the evidence on what it can deliver in the clinic. In the early 2000s diabetologists began reporting an unusually low rate of cancer among their patients who were treated with metformin. What happened next seemed to follow a ‘false-dawn’ pattern that has become all too familiar in the history of cancer research. A series of epidemiological studies came out showing large effect sizes, some showing cancer rates more than halved in metformin users – results that wiser heads cautioned were simply “too good to be true”. But then attempts to back up the findings with lab studies confounded the sceptics: whether used against cancer cells in petri dishes or against tumours in mice models, metformin did indeed inhibit cancer growth. “That was the golden period,” says Michael Pollak, whose lab at the Mc Gill translational research centre in Montreal, Quebec, was one of those tasked with carrying out the research.

    Sometimes I get so frustrated, seems everything makes us sick or cause something else to get worse. Since then, I have started noticing that my eyes ache, a sort of dry, painful ache. This time is different, no blood, just constant pain. I do not know if it is related to my bladder cancer as I was diagnosed in 2014, but I will for sure check into because I have two more tumors and possibly will have to do a 6 week of BCG and once a month for 2 years. I have been taking Metformin 500mg for about four months to lower my Al C. I have been prone to UTI's in the past, but always with different symptoms such as pain while urinating, fullness, and blood in my urine. I took it for almost a year a few years back and it made me feel terrible. I went to my GYN yesterday and she did a urine culture and sent me for an internal pelvic ultrasound, both for which I am waiting the results. The ultrasound became extremely painful, I did not know if I would be able to handle her continuing. I am anxious to get my results, but can only wonder if taking Metformin has something to do with my symptoms since all of this started after I began taking it. This just may be a coincidence but I had symptom of burning upon urination. I felt it was caused by something in my diet or meds.

Meanwhile, preexisting diabetes is associated with an increased risk of all-cause and cancer-specific mortalities.

Association of diabetes as a growing and costly disease with cancer is a major health concern. Presence of diabetes related comorbidities, poorer response to cancer treatment, and excess mortality related to diabetes are among the most important explanations. Although diabetes appear to be a risk factor for cancer and is associated with the mortality risk in cancer patients, several factors such as diabetes duration, multiple drug therapy, and the presence of diabetes comorbidities make the assessment of the effect of diabetes treatment on cancer risk and mortality difficult. Metformin is the drug of choice for the treatment of type 2 diabetes. The available evidence from basic science, clinical, and population-based research supports the anticancer effect of metformin. However, randomized controlled clinical trials do not provide enough evidence for a strong protective effect of metformin on cancer incidence or mortality.
