Final answer:

Radiation therapy is recommended for tumors under 4cm and can decrease the recurrence rate to 30%. It uses ionizing radiation to kill cancer cells by delivering a concentrated dose to the tumor while minimizing damage to surrounding healthy tissue.

Step-by-step explanation:

Radiation therapy is recommended for tumors under 4cm. Post-op radiation can decrease the recurrence rate to 30%. Radiation therapy uses ionizing radiation, such as X-rays, to kill cancer cells.

The technique involves directing multiple rays from different angles at the tumor to deliver a concentrated dose while minimizing damage to surrounding healthy tissue.
