Forearm Hair Density And Risk Of Keratinocyte Cancers In Australian Adults

The study investigated the relationship between forearm hair density and the risk of keratinocyte cancers (BCC and SCC) in Australian adults, involving 715 participants with an average age of 61 years. It found that individuals with dense forearm hair had a higher incidence of BCC (IRR = 2.24) and SCC (IRR = 2.80) compared to those with sparse hair. Men with dense hair were more likely to develop SCC (IRR = 3.01), and women with moderate hair density were more likely to develop BCC (IRR = 2.29). The findings suggested that higher body hair density might be associated with an increased risk of these skin cancers.
