A bit more context

Clear cell renal cell carcinoma is the most common form of kidney cancer in adults and is considered one of the more aggressive subtypes. It gets its name from how the cancer cells look “clear” under a microscope because of stored fat and glycogen. In Arnold’s case, doctors classified it as stage 4 because it had already spread beyond the kidney to his lung.
