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 are the most common type of kidney cyst. They are not the same thing as polycystic kidney disease, which is a progressive disease that can lead to kidney failure. Simple kidney cysts most often do not cause harm.
