Are targeted drugs for bladder cancer good?

Bladder cancer has stages, and highly malignant bladder cancer is more likely to take people's lives. It can be said that bladder cancer is very harmful, with symptoms of hematuria and urinary retention, and patients in the late stage are more likely to metastasize. Regardless of the stage of bladder cancer, patients need to face it positively. Patients should not be depressed because of the presence of cancer. On the contrary, they need active treatment, and when receiving treatment, they should not believe in quack doctors, but go to a regular hospital for treatment. What are the benefits of targeted drug treatment for bladder cancer?

We know that some non-muscle-invasive bladder cancers require surgery, but even after surgery, 70 percent of bladder cancer patients are more likely to relapse, and 70 percent of bladder cancer patients have tumors that invade the patient's muscle layer.
Bladder cancer patients need to undergo intravesical chemotherapy through the urethra. They can also take immunotherapy to eliminate residual tumors after surgery. The main immunomodulatory drug for targeted drug therapy of bladder cancer is BCG.
