Dana,
Where in Europe (city/country) are you located? That can help if anyone then knows of top bladder cancer doctors within a reasonable distance.
The growths are typically called "tumors".
So, in English, the surgery to remove them is called a TURBT (TransUrethral Resection of Bladder Tumor(s). TransUrethral just means they go through the urethra to get into the bladder as opposed to open surgery.
What is important is the stage and grade of the tumors. Stage is how deep into the bladder the cancer is and grade is how aggressive the particular cancer is. Usually Grade is Low or High but there are some numbers used for that as well (1=low; 3=high).
It is certainly a scary time for you and your husband. Many of us have been in that same situation already and we understand.
Once you have the results from the pathology reports, it will determine what the next steps are. If caught early, bladder cancer is very treatable. However, it is often under-staged, so that second surgery to go back and make sure they got it all is very important. Understaged means they didn't get a deep enough sample to have clear margins so they can think it is only surface layer when it is actually deeper. That is why it is so important that they get good clear margins around any samples they take so they know exactly how deep it has gone. It is often caught when it is still on the innermost layer.
You and your husband are not alone. There are a LOT of bladder cancer survivors in the world and there are a bunch of here who are happy to answer questions.
If he was already "diagnosed" did you get a copy of the pathology report yet? If not, ask the doctor for a copy. If he/she doesn't want to give it then ask the hospital where the surgery was performed.
