Question

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.
○ there are no side effects from radiation therapy.
○ radiation can be used on a tumor found anywhere in the body.
○ radiation therapy can be done from home.

Explanation:

• Option 1: Radiation therapy can be precisely targeted at cancer cells, minimizing damage to surrounding healthy tissues. This is a key advantage over some medications which may have more widespread effects.
• Option 2: Radiation therapy does have side - effects such as fatigue, skin irritation, etc. So this option is incorrect.
• Option 3: While radiation can be used on many tumors, it is not true that it can be used on any tumor anywhere in the body. There are anatomical and physiological limitations. For example, tumors near critical organs with high radiation sensitivity may be difficult to treat with radiation alone.
• Option 4: Radiation therapy requires specialized equipment in a hospital or clinic setting and cannot be done from home.

Answer:

Radiation is targeted directly toward the cancer cells.
