Worldwide approximately 6 lac new patients are diagnosed annually with squamous cell head and neck cancer. RT and surgery are the major curative modalities in treatment of head and neck cancer. With the currently available photon technology, sparing of nontarget tissues is frequently difficult, as target volumes in head and neck cancers are generally large, complex in shape, and surrounded by critical normal structures which may lead to higher incidence of toxicities. So patients suffer from both acute and late toxicities during and following radiotherapy like mucositis, xerostomia, radiation dermatitis, trismus etc. which largely compromise their qualities of life. Hence necessitates the emergence of new and modified radiation techniques along with some pharmacological approaches and life-style modifications to combat this problem. Over the last few decades, conventional RT which used simpler rectangular treatment fields has changed significantly to conformal RT techniques. The use of 3D CRT, IMRT, IGRT, Adaptive RT, VMAT, Proton beam therapy etc. and improved imaging techniques for target volume and organ at risk delineation have accompanied efficacy improvements in decreasing acute and late toxicities by sparing normal tissues and hence dose escalation to tumors. Along with advancements in RT techniques, some simple life-style modifying education and a few pharmacological approaches also help to alleviate poor quality of life of these patients. In this context, this article will focus on some of these technical advancements along with other general approaches to minimize post-RT complications in head-neck cancer patients. The scope of improved treatment delivery in the perspective of Bangladesh will also be mentioned briefly [ABSTRACT FROM AUTHOR]
