I have seen minimal information relating bladder cancer to the use of drugs such as lisinopril. There have been, as you have seen, reports linking these drugs to a small increase in lung cancer. However, the discussion portions of several of these reports note that patients with hypertension tend to be smokers more often than patients who do not have hypertension, and smoking is linked to lung cancer as well as to bladder cancer.
Any recall of lisinopril that I have seen has been due to contamination with either metal fragments or other chemicals, not because of a cancer-related issue.
Most of us will never know what led to our diagnosis of bladder cancer (it is supposed to be a disease of elderly smoking males and I am a non-smoking not-quite-elderly at diagnosis female). This is true of most cancers.
So glad to hear that your father is doing well after his surgery.
