Hair dye study
Women who regularly dyed their hair prior to 1980 have a 20% higher risk of developing lymphoma compared to women who have never dyed their hair, according to an unpublished study presented by the International Agency for Research on Cancer at the International Conference on Malignant Lymphoma June 8. Study included approximately 4,800 people across seven European countries, half of whom had lymphoma, and found that 73% of women and 7% of men regularly dyed their hair. However, "it is reassuring to notice that dyes used in the last 25 years do not seem to carry an increased risk," IARC says. Research corroborates recent findings of a large-scale U.S study that also identified an increased lymphoma risk among subjects who used hair dye prior to 1980 (1"The Rose Sheet" Feb. 2, 2004, p. 11)...
