Adding radiotherapy to vaccination could prevent millions of deaths from cervical cancer in low- and middle-income countries Princess Margaret Cancer Centre researchers show economic impact of cervical cancer left untreated in low- and middle-income countries from 2015-2035. 85 per cent of cervical cancer deaths occur in low- and middle-income countries making it one of the greatest public health challenges as women live longer. Universal vaccination alone results in a 3.9 per cent decrease in new cases over 20 years. Millions of women will require radiotherapy treatment in addition to vaccination to save lives in low-and middle-income countries. 9.4 million women will die without radiotherapy treatments, even with vaccination. 11.4 million life years gained by investing in radiotherapy. $151 billion in economic benefit if women’s lives are saved by adding radiotherapy treatment.
