Dear editor
This letter is regarding our concerns regarding the paper entitled “The Association between Smartphone Use and Breast Cancer Risk among Taiwanese Women: A Case-Control Study” by Shih et al, published in Cancer Management and Research.

1 Although this paper addresses a very important topic, it has some shortcomings that at least to some extent, affect its conclusion. In their case-control study on 894 healthy controls and 211 patients with breast cancer, the authors had asked the participants to provide information on their sleep quality, smartphone addiction, and smartphone use. Shih et al. concluded that heavy smartphone use could be linked to increased breast cancer risk, particularly in phone-addicted individuals, and in cases who had placed their smartphones at a close distance with their breasts and those who used to use their smartphone before bedtime.
