Bladder tumors are abnormal growths that occur in the bladder. If the tumor is benign, it’s noncancerous and won’t spread to other parts of your body. This is in contrast to a tumor that’s malignant, which means it’s cancerous.

Papillomas (warts) are common viral skin growths. They’re usually harmless.

Leiomyomas are the most common benign tumor found in women. That said, they’re rarely located in the bladder: According to a on bladder leiomyomas, they account for less than 1 percent of all bladder tumors.

Leiomyomas form in the smooth muscle cells. Those that develop in the bladder can continue to grow and may result in symptoms such as obstruction of the urinary tract.

Fibromas are tumors that form in the connective tissue of your bladder wall.

Hemangiomas occur when there is a buildup of blood vessels in the bladder. Many hemangiomas are present at birth or during infancy.

Neurofibromas are categorized as tumors that develop in the nerve tissue of the bladder. They’re very rare.

Lipomas are tumor growths of fat cells. They’re often caused by an overgrowth of such cells. Lipomas are fairly common and usually don’t cause any pain unless they press against other organs or nerves.
