Recent research has covered the genetic polymorphisms of CYP1A1 carried weight with the risk of developing cancers containing lung cancer (Kudhair et al., 2020), upper digestive tract cancer (Tian et al., 2019; Zhao et al., 2019), and thyroid carcinoma (Bufalo et al., 2006; Figlioli et al., 2016). Here, CYP1A1 is linked to lung carcinoma.
