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.
In most cases, simple kidney cysts do not cause symptoms and usually do not require treatment. However, in some cases simple kidney cysts can grow large enough and cause a dull pain in a person's back, side or upper abdomen. These cysts can also get infected, causing pain, fever and tenderness. They can burst, also causing pain. Simple kidney cysts rarely harm kidneys or impair their ability to function.
