While not a major commercial product, PFOS itself has been used in some products, including fire fighting foams `The mechanisms and pathways leading to the presence of PFOS in human blood are not well characterized but likely involve environmental exposure to PFOS or its precursor `molecules and residual levels of PFOS or PFOS precursors in industrial and commercial 000072 3M Company Pasas: products.

Under a multistage model that allows for clonal expansion, very low clonal expansion rates should lead to negligible divergence from the classical Armitage-Doll multistage model (8); in contrast, a very rapid round of clonal expansion would effectively reduce by 1 the number of steps in the process (11).
