How many radiotherapy sessions are needed for oral cancer?
Radiation therapy is delivered in doses called fractions—typically once daily, five days a week, for six or seven weeks. Intensity modulated radiation therapy may be combined with chemotherapy.
What are the effects of radiotherapy on the oral mucosa?

What are the doses of radiotherapy?

What is the success rate of radiation therapy for oral cancer?
The data for this group suggested that the 5-year survival rate was 52.5% among patients treated only by surgery, and 56.0% among patients who had received both radiotherapy and surgery.
How long does it take to feel better after radiation?
The general effects of radiation therapy like fatigue, nausea, and headaches resolve fairly quickly after treatment. Your body just needs time to process the radiation but can recover within a few weeks.
How long is a session of radiotherapy?

The cost of radiation therapy was estimated from Medicare reimbursements. The median cost for a course of radiation therapy per patient was $8600 (interquartile range [IQR], $7300 to $10300) for breast cancer, $9000 (IQR, $7500 to $11,100) for lung cancer, and $18,000 (IQR, $11,300 to $25,500) for prostate cancer.
Does radiotherapy damage your teeth?
Radiotherapy increases your risk of dental decay. Fluoride helps prevent decay by hardening the teeth. Harder teeth resist decay more effectively.
