Customer Question

My mother passed away last September of bladder cancer. She was taking a lot of medication (all prescribed) but I've notice metformin may cause this type of problem. She was taking 5 mg 2x daily. This was for type 2 diabetes. Her only sister also has bladder cancer.
Could her condition have been caused by the medication?

Hi there,

I am sorry to hear about your loss.

Metformin has not shown to cause bladder cancer.

In fact, some studies suggested that metformin may reduce the risk of bladder cancer.

Type 2 diabetes itself poses a higher risk for bladder cancer.

Some anti diabetic medications like pioglitazone, or rosiglitazone can increase the risk of bladder cancer.

But metformin is not a problem.

Again my commiserations for you.

Best wishes,

It was my pleasure to help you today.
