Question 8 • Physics in the Universe

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

Answer
A
radiopharmaceuticals
B
high intensity focused ultrasound
C
superficial external beam radiation therapy
D
brachytherapy

Explanation

A small skin cancer close to the surface can be treated with superficial external beam radiation therapy, which directs radiation at the affected area from outside the body. Brachytherapy places a radiation source in or near a tumor, while high-intensity focused ultrasound and radiopharmaceuticals are not the usual choice for a small skin spot.
