Studies indicate that sensitivity to mutagens is increased in patients with environmentally
related cancers. This sensitivity can be evaluated by treating an individual's lymphocytes
in culture with bleomycin and counting the resulting number of chromatid breaks. In combination
with exposure to carcinogenic assaults, this sensitivity greatly influences cancer risk assessment,
suggesting that it is a cancer susceptibility factor. Cloos et al. (p. 1125) studied the heritability of the susceptibility to DNA damage by evaluating chromatid breaks in
the following three groups: 1) family members (siblings
