What is the most common site of metastasis for renal cell carcinoma?

Explanation:
RCC tends to spread through the bloodstream, and the renal vein drains directly into the systemic circulation. Tumor cells entering the renal vein reach the right heart and are pumped to the lungs, so the lungs are the first and most common site where RCC cells lodge and grow. While metastases can occur in bone, liver, or brain, they occur less frequently than in the lungs. Therefore, the lungs are the most common metastatic site for renal cell carcinoma.
