What are the symptoms of a kidney cancer before it is full blown?

Kidney cancer often doesn't cause any noticeable symptoms in its early stages. As the tumor grows, possible signs and symptoms may include:

- Blood in your urine (hematuria). This is often the first sign of kidney cancer. The blood may be visible or it may be detected only through a urine test.

- Pain in your side or back, between your ribs and hips.

- A mass or lump in your abdomen or side.

- Weight loss.

- Fatigue.

- Fever.

- High blood pressure (hypertension).

- Anemia.

- Swollen legs or ankles.

- Increased thirst.

- Frequent urination.
