6. Puffed-up ankles and feet

Swollen ankles and feet are normally associated with pregnant women. They are seen as a sign of a new life, but swollen ankles are a symptom of something oppositely sinister too. Any kidney disease including kidney cancer can cause your feet and ankles to puff-up.

A cancerous tumor in Kidney can cause it to function improperly. When kidneys are not functioning properly, as a result, a fluid can build up in the body. This fluid settles in the feet. This process causes the feet to swell up. A patient particularly feels weak in the ankles. Walking starts to feel like a difficult task.
