multiple choice question
often both radiation and medications are used to treat cancer. high energy rays in radiation therapy are used to treat tumors by damaging the dna in cancer cells.
what is one benefit radiation therapy has over taking medication for cancer treatment?
○ radiation is targeted directly toward the cancer cells.
○ radiation therapy can be done from home.
○ there are no side effects from radiation therapy.
○ radiation can be used on a tumor found anywhere in the body.

Explanation:

• Radiation therapy is a local treatment, meaning it can be precisely targeted at the tumor site (cancer cells), minimizing damage to surrounding healthy tissues compared to medications (which are systemic and affect the whole body).
• Radiation therapy cannot be done from home as it requires specialized equipment in a medical facility.
• Radiation therapy does have side - effects such as fatigue, skin irritation, etc.
• While radiation can be used on many tumors, it is not applicable to all tumors found anywhere in the body (e.g., some tumors in sensitive or hard - to - reach areas may have limitations).

Answer:

Radiation is targeted directly toward the cancer cells.
