How much does 6 weeks of radiation cost?

I'm curious, could you please elaborate on the cost of undergoing six weeks of radiation treatment? Is this a standard price across all medical facilities, or does it vary depending on factors such as location, insurance coverage, and the specific type of radiation therapy being administered? Additionally, are there any potential additional costs that patients should be aware of, such as medication, follow-up appointments, or travel expenses? Understanding these details would be greatly appreciated.
