The pooled analysis included 4,461 females with NHL and also 5,799 girls who did not have NHL.

Although these outcomes are in accordance with the notion the hair dyes are somewhat more carcinogenic, it's also possible the absence of raised dangers for hair dye people that began utilizing dyes later 1980 reflects lower cumulative vulnerability ranges or inadequate period since first vulnerability for any growth in hazard to develop into evident.
