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.
Simple cysts do not need any intervention or further follow up. Complex cysts, however, do need further attention. Complex cysts pose a concern because a subset of complex cysts may have cancerous growth. Of note, most cancerous growths in the kidney are solid, not cystic. Yet some cancers of the kidney may have a cystic component.
