Ultrasound uses sound waves to make pictures of your insides. It can help show the size of a bladder cancer and whether it has spread beyond the bladder. It can also be used to look at the kidneys.
This is an easy test to have. You simply lie on a table while a kind of wand is placed on the skin over the part of your body being looked at. No radiation is used.
Ultrasound can also be used to guide a biopsy needle into an area where cancer may have spread.
