A bladder mass is any large lump, tumor, or cyst that is found on the bladder or in the immediate area. The mass may be noticed after symptoms arise or during a pelvic exam regarding another condition. Not all instances of a bladder mass indicate cancer, but since it is a risk, a biopsy may be performed. In some cases a mass may be detected during certain urine tests.

One type of bladder mass is a cyst. In most cases, a bladder cyst is not cause for alarm unless it is blocking urine flow or causing extreme pain. These cases may require surgery to remove the mass, or the underlying cause of the cyst’s development may need to be determined to cause it to shrink or go away entirely.

The other major type of bladder mass is bladder cancer. Bladder cancer is much more common in men than in women, but it is a leading type of cancer diagnosis for both sexes. If cancer is suspected once a mass is found, additional tests may be done to determine if the mass is malignant or benign. Malignant tumors are those that are determined to be cancerous, and additional treatment will be necessary.
