Retinoblastoma is a rare eye cancer that typically affects children under age 5, starting in the retina and often noticed as a white pupil, crossed eyes or eye swelling. Early detection is key to protect vision and life. Causes include DNA mutations, sometimes inherited, leading to uncontrolled cell growth in the retina. Treatment options range from chemotherapy, laser and cryotherapy to surgery, tailored to tumour size and spread. With expert care from Dr Nandini Hazarika, children receive timely diagnosis and personalised treatment plans to improve outcomes and preserve sight.
