________ is a technique in which cancer cells are damaged with radiations, while limiting the harm to nearby healthy tissue.

Radiotherapy

The correct answer is Option (1) - Radiotherapy

The technique in which cancer cells are damaged with radiations while limiting the harm to nearby healthy tissue is known as Radiotherapy.

Radiotherapy: Radiotherapy, also called radiation therapy, is a medical treatment that uses ionizing radiation to target and kill cancer cells. It is a localized treatment aimed at a specific area of the body where cancer is present. High-energy radiation is directed at the cancer cells, damaging their DNA and preventing them from dividing and growing. The goal is to destroy or shrink the tumor while minimizing the impact on nearby normal cells.

Combination with Other Treatments: Radiotherapy is often used in combination with other cancer treatments such as surgery, chemotherapy, or immunotherapy, depending on the type and stage of cancer.

Side Effects: While radiotherapy aims to target cancer cells, it can also affect nearby normal cells, leading to side effects. The severity of side effects depends on factors such as the type of cancer, the location of the tumor, and the overall health of the patient.
