Head and neck cancer includes a heterogeneous gathering of tumors emerging from the upper aero-digestive tract, paranasal sinuses, and salivary and thyroid glands. The ideal administration of head and neck cancer requires a multidisciplinary approach. Surgery and radiotherapy are the significant treatment modalities. The significant objective of radiotherapy is to accomplish local control of the tumor while limiting harm to the critical organs. Radiotherapy for patients with head and neck malignancy is amazingly intricate and has advanced incredibly in the previous decade, attributable to the coming of conformal and force balanced radiotherapy procedures. Impressive variety practically speaking arrangement exists among organizations. The degree of essential tumor and neck lymphadenopathy of different subsites and the pathologic discoveries direct the proper radiation fields, portion, and fractionation. Customization of the treatment methods is fundamental. For most privately progressed head and neck disease, medical procedure and postoperative radiotherapy are corresponding, a blend of the two modalities accomplishing the ideal outcome. Careful expulsion of gross tumor may kill the significant wellspring of illumination disappointment, and radiotherapy may sanitize tiny tumor spread past the careful edges, which is the significant wellspring of repeat after a medical procedure. As of late, the blend of chemotherapy and radiotherapy has been acquainted with increment tumor control and safeguard organ uprightness. Ongoing advances in radiation material science, PC innovation, imaging innovation, and radiotherapy office have significantly improved the therapy arranging and conveyance of radiotherapy. Technologic advances, for example, converse therapy arranging and the multileaf collimator-prepared direct gas pedal have prompted the fruitful execution of intensity-modulated radiation therapy (IMRT). IMRT is a high level type of three-dimensional conformal radiotherapy utilizing PC upgraded backwards treatment arranging and a PC controlled multileaf collimator. With these methods, the power of radiation can be regulated so a higher radiation portion can be conveyed to the objectives with a forcefully conformal target volume inclusion, while simultaneously the portion to the encompassing ordinary tissues is notably diminished. Hence, radiotherapy can be conveyed in manners that safeguard however much of basic organs and capacities as could be expected. IMRT has been pervasive lately in the therapy of head and neck cancers, which have end upbeing the ideal objective for its execution. In the head and neck district, organ movement is essentially irrelevant. Numerous radiosensitive basic organs, like the spinal rope, cerebrum stem, and parotid organ, are in closeness to the objectives. Fruitful execution of IMRT requires profoundly exact patient arrangement and immobilization, ideal imaging modalities, sufficient objective volume outline, and fitting assurance of portion volume limitations. The ideal fractionation conspires for IMRT has not been convincingly characterized, notwithstanding broad examination endeavors. More examination is expected to assess distinctive fractionation plans. Complications The huge treatment volume used in head and neck cancers can incite acute and late complications. Complication rates are expanded in patients with simultaneous chemotherapy or coinciding medical diseases such as diabetes. With current threedimensional conformal radiotherapy techniques, radiationrelated intricacy rates can be reduced. Acute Complications: Acute mucositis reflects fundamentally the immediate harm of the irradiated mucosa and addresses the most common dose-limiting side effect of radiotherapy. Patients may encounter irritation of throat and mouth. Late Complications: Xerostomia was by a long shot perhaps the most widely recognized radiation-related complications. Xerostomia ordinarily happens by the third week of radiotherapy and continues after the finishing of treatment. The level of xerostomia is largely dependent on the radiation portion and the volume of the major salivary glands inside the radiation fields. Loss of capacity of salivary glands is normally lasting after radiation dosages of 35 Gy.
