Haley noticed a small spot on her skin that turned out to be skin cancer. Which treatment is her doctor most likely to use?

Superficial external beam radiation therapy directs radiation from outside the body onto or just beneath the skin, making it suitable for treating a small skin cancer spot. Brachytherapy places a radioactive source inside or next to a tumor, radiopharmaceuticals deliver radioactive drugs through the body, and focused ultrasound uses sound waves rather than radiation.
