Doctors use chemotherapy, radiation therapy, surgery and biologic therapy to treat papillary carcinoma, also known as stage 0a bladder cancer, according to the National Cancer Institute. Ongoing clinical trials also test advanced treatments to eradicate cancerous cells and tumors of the bladder.
The surgical procedure known as transurethral resection with fulguration burns away the papillary carcinoma tumors that invade the lining of the bladder, as detailed by the National Cancer Institute. Biotherapy utilizes bacillus Calmette-Guérin to stimulate the immune system and allow the body to fight off the cancer itself. High-energy X-ray machines use radiation to shrink or kill bladder tumors, while internal radiation therapy employs needles to deliver radioactive substances to the direct site of the bladder lining affected by papillary carcinoma.
