Patients with a type of bladder cancer called NMIBC need special treatment after their surgery to help prevent the cancer from coming back, and they usually get a medicine called BCG.
There have been issues figuring out the best way to use BCG since not everything about how it works is clear, and this has changed how doctors treat the cancer over the years.
Recently, there have been shortages of BCG, leading doctors to change their treatment plans and look for new ways to help patients feel better and improve their chances against cancer.
