Can kidney cysts develop into kidney cancer?

More and more kidney cysts are being discovered. How to deal with these cysts is very frustrating for the people involved. Although most kidney cysts are benign, which ones are malignant? Are those cystic kidney cancers the result of cystic transformation? This is a question that is often asked. Sometimes it is difficult to explain clearly because it would hurt people. More often, it is impossible to explain clearly because many scientific issues have not yet been clarified.

Does cystic renal cancer develop from a cyst? So far, there is no scientific evidence to answer this question. Based on my personal knowledge and experience, a cyst is a cyst and cystic renal cancer is cystic renal cancer. There is no relationship between them.
How to distinguish renal cysts from cystic renal cancer? There are two points to pay special attention to. First, we must understand the characteristics of renal cysts and cystic renal cancer. Second, plain scan + enhanced thin-layer scan must be performed to diagnose and distinguish renal cysts from cystic renal cancer. According to the characteristics of CT scans, cystic space-occupying lesions of the kidney are divided into simple renal cysts and complex renal cysts. The former has a smooth inner wall without partitions, while the latter has partitions, an uneven inner wall or nodules. In particular, if the inner wall is irregular with nodules and the nodules are enhanced on the enhanced CT scan, it is highly suspected to be cystic renal cancer. In fact, some renal cysts with such manifestations are cystic renal cancer after surgical resection and pathological examination.
