8. Swelling of the Legs and Ankles
Edema is the accumulation of fluid in the body’s tissues, especially the extremities.
Swelling caused by edema can be a tell-tale kidney cancer symptom, as impaired kidney function often means that sodium in the body isn’t adequately eliminated and builds up, causing you to retain water. (23)
9. High Blood Pressure
Medical research on kidney cancer symptoms has found a connection between hypertension (high blood pressure) and renal cell carcinoma.
In a 2009 study, 79.3% of people with kidney cancer also experienced high blood pressure.
Additionally, cardiovascular disease is a risk factor for kidney cancer; in this particular study, the data suggested that renal cell carcinoma can cause hypertension. (24)
