These chemotherapy medicines are called antitumor antibiotics. These antibiotics are not like the antibiotics used to treat infections. Instead, these antitumor antibiotics interfere with the DNA inside cells. This slows or stops cancer cells from growing and keeps them from multiplying.
Why It Is Used
Antitumor antibiotics are used to treat leukemia and cancer, such as bladder cancer.
Mitomycin is used to prevent bladder cancer from
coming back (recurring). It is given through a
urinary catheter directly into the bladder.
How Well It Works
These medicines work well in treating cancer. But the type and extent of the cancer affects how well this medicine slows or stops the growth of those cancer cells.
