More boys than girls with cancer in India are being diagnosed with the disease and the probable cause for this is gender bias in society, according to a study published in The Lancet Oncology.

 The researchers collected individual data of children aged 0-19 years with cancer extracted from the hospital-based records of three cancer centres in India between January 1, 2005, and December 31, 2019. 

 They also used data from two population-based cancer registries: PBCRs in Delhi between January 1, 2005, and December 31, 2014 and Madras Metropolitan Tumour Registry between January 1, 2005 and December 31, 2017. 

 The researchers from All India Institute of Medical Sciences, New Delhi and Cancer Institute (WIA) Chennai calculated the male to female sex ratio from the three hospitals in the context of the ratio in the corresponding PBCRs. 

 This ratio allowed them to see how many boys with cancer were seeking treatment for each girl seeking treatment. The team separately analysed the male to female ratios of patients undergoing stem cell transplant which is a comparatively expensive procedure used in cancer care. 

 "We observed that among nearly 11,000 patients registered in the PBCRs, there was significant skew in favour of boys for getting diagnosed with cancer. Similarly, among the 22,000 children with cancer enrolled in the three hospitals, we saw that more boys were seeking treatment than girls," said Professor Sameer Bakhshi, from Department of Medical Oncology, AIIMS New Delhi.
