All We Need To Know About Medical Uses of Radiotherapy

A cancer's radiosensitivity describes how it reacts to radiation. Modest radiation dosages quickly kill cancer cells that are highly radiosensitive. Leukemias, the majority of lymphomas, and germ cell cancers are among these. Since most epithelial tumours are only moderately radiosensitive, a radical cure requires a much greater radiation dose (60–70 Gy). Certain cancers are especially radioresistant, meaning that considerably greater doses than are likely safe in clinical practise are needed to provide a drastic cure.


Radiotherapy is still a palliative option for many patients with metastatic melanoma despite the fact that radiation resistance is typically associated with renal cell carcinoma and melanoma. An ongoing field of research that has shown some promise for treating melanoma and other malignancies is the combination of radiation therapy with immunotherapy.


If the draining lymph nodes are clinically or radiologically associated with the tumour, or if there is a possibility of latent malignant dissemination, the radiation fields may additionally include those nodes in addition to the tumour itself. To account for uncertainties in daily setup and internal tumour mobility, a margin of healthy tissue must be present around the tumour. These ambiguities may be brought on by both internal movement (such as breathing and bladder filling) and outward movement of skin markings in relation to the tumor's position.


In contrast to radiology, which uses radiation for imaging and diagnosis in medicine, radiation oncology is the branch of medicine that deals with prescribing radiation. A radiation oncologist may prescribe radiation with the goal of curing cancer ("curative") or as adjuvant therapy.
