What Is Kidney Cancer?

The main function of the kidney is to filter blood for electrolytes and urinary waste to produce urine. Kidney cancer is one of most lethal cancers, yet many kidney tumors are detected at an early stage when they are small and very curable.

These small renal masses (under 4 cm) can be treated or observed with outstanding survival rates. Compared to early cancers, those kidney cancers that have spread to lymph nodes or other parts of the body often require systemic therapy.

At Northwestern Medicine, we treat the entire spectrum of kidney cancer from patients with early to advanced cancers.
