Q | what are the symptoms and signs?
A | The classic symptoms and signs include an abdominal mass, loin pain overlying the kidney and haematuria. Although these are classic symptoms they may only occur in 20% of patients with RCC.
The sudden appearance of a left sided varicocele should also alert your specialist to have a closer look at the kidneys. Occasionally, a tumour of the left kidney can be large enough to block the venous drainage from the left testicle causing a varicocoele to appear in the scrotum.
In 25% of patients, paraneoplastic syndromes may occur. These are disorders of the other systems of the body seemingly not related to the kidney problem itself. They appear to be caused by the release of chemicals from the cancer cells and include, for example, problems with high blood pressure and the body's hormone control.
