I would definitely want to know if they are going to remove more than three or four lymph nodes. It actually is not beneficial for people to have a lot of lymph nodes removed. In some cases, people have had to have shunts to remove liquid created from them removal of lymph nodes that weren’t properly cauterized.

If you had a PSMA pet scan, they would know if any of the lymph nodes lit up and needed to be removed. Somebody with a 3+4 that is isolated to the prostate and caught early really wouldn’t need to have many lymph nodes removed. I was a 3+4 going into surgery and they did not remove any lymph nodes. I’ve never had a problem with them in the 16 years since.

Here is some more information about this

Lymph nodes aren't just passive waiting rooms for immune cells, they actively train and educate T cells, and send them off to do their job," said Professor Axel Kallies, PhD, Laboratory Head at the Doherty Institute and the corresponding author on both studies. "Our research suggests that removing lymph nodes during cancer surgery, a common practice to prevent tumor spread, may inadvertently reduce the effectiveness of treatments, such as checkpoint blockade and CAR T cell therapies. Preserving lymph nodes could strengthen immune responses and increase the effectiveness of immunotherapy."

But what are lymph nodes, and what do they do?
Lymph nodes are small, bean-shaped organs scattered throughout the body that act as checkpoints of the immune system. They filter lymph fluid, which drains from tissues, trapping and destroying germs, cancer cells, and other harmful material. Inside, lymph nodes are packed with immune cells like T cells, B cells, and dendritic cells that communicate, train, and multiply in response to threats.
