Bacillus Calmette-Guérin treatment

Bacillus Calmette-Guérin (BCG) treatment is an immunotherapy used mainly for bladder cancer. It involves injecting a weakened form of the bacteria that causes tuberculosis directly into the bladder. This stimulates the body's immune system to recognize and attack cancer cells lining the bladder. BCG treatment is typically given in multiple sessions and can help prevent cancer recurrence and progression. While effective, it can cause side effects like bladder inflammation or discomfort, but serious reactions are rare. Overall, BCG leverages the body's immune response to fight bladder cancer more effectively.
