A member asked:

If a 1cm complex kidney cyst has been stable in size for 4 months, what are the chances it is cancer and is it possible for it to spread at this size?

Renal cyst: The fact that it is small and stable after 4 months is a good sign. However another renal ultrasound should be done in 6 months to look for growth or change in structure. There is an increased risk of malignancy with a complex cyst and it should be watched closely
