Elaborate on the practicality of radiation therapy in the treatment of cancer.

A. Radionucleotides are minimally effective in cancer treatment and are only used when the cancer is near the skin surface.
B. Modern radiation therapy is effective because the isotopes used have fairly short half-lives and are absorbed mainly by damaged cells.
C. Radiation therapy is a last resort for cancer patients due to its inability to target cancerous cells, therefore also killing many normal cells.
D. Many different radionucleotides are used in cancer treatment due to their ability to completely eradicate the damaged cells with no adverse effects on the patient.

Final answer:

Radiotherapy is a valuable cancer treatment due to the sensitivity of cancer cells to radiation and the focus on maximizing the therapeutic ratio.


Explanation:

Radiotherapy is an effective cancer treatment method as cancer cells are more sensitive to radiation due to their rapid reproduction. The key challenge in radiotherapy is maximizing the dose to cancer cells while minimizing it to normal cells, known as the therapeutic ratio. Various techniques, like using different types of radiation beams, help concentrate the radiation in tumor tissues while minimizing exposure to normal tissues.
