Explanation:

The text mentions that chemo can kill cancer cells (so "kills cancer cells" is a benefit). It can shrink tumors ("shrinks tumors" is a benefit). It can stop cancer from growing and spreading ("stops cancer from spreading" is a benefit). It can work throughout the whole body ("works throughout the whole body" is a benefit). Also, chemo can help shrink a tumor that's causing pain or pressure (so "decreases pain" and "reduces pressure" are benefits as the tumor - related pain and pressure are lessened when the tumor is shrunk). Chemo is a drug treatment, so "provides a drug - free treatment" is incorrect. Surgery removes tumors, not chemo, so "removes tumors" is incorrect.

Answer:

decreases pain, shrinks tumors, kills cancer cells, reduces pressure, stops cancer from spreading, works throughout the whole body
