diabetes, type 2
"My brother was prescribed Invokana almost three years and developed a cancerous tumor in his kidney.  it was a very complicated surgery because of where the tumor was located and because of that the entire kidney had to be removed.  he was taking 300 mg.  upon diagnosis the surgeons instructed my brother to stop the medication immediately.  my brother never had any kidney problems in his whole life.  let this be a warning."
