Free on board (FOB) is a contractual term that refers to the requirement that the seller deliver goods at the seller's cost via a specific route to a destination designated by the buyer. How It Works To understand how FOB terms work, let's look at an example.
A kidney cyst or renal cyst, is a fluid collection within the kidney. Most kidney cysts are âsimpleâ or âbenignâ meaning no treatment is required. Some cysts are more âcomplexâ and require either close radiographic imaging (with either a CT scan or MRI) or surgery since these cysts can be cancerous.
Renal cysts occur in a variety of genetic diseases in adults and children, but simple renal cysts are commonly observed in normal kidneys. They are so common, it is difficult to consider them a disease.
