The greatest risk factor is the tar from cigarettes, which places smokers at twice the risk of developing bladder cancer. The key to curing bladder cancer is detecting it early.

Larger tumors may require more intense surgery, with chemotherapy or radiation therapy used to kill any remaining cells. For more information about bladder cancer, contact a health care professional. Most bone tumors are considered secondary tumors because they have developed from cancer cells spread from a primary malignant tumor to the bone. Both of these are much less common than cancer that travels to a bone. Generally, bone tumors are benign.
