“…Reproductive factors, including age at menarche (7, 9, 10, 16), age at menopause (5, 8, 16), age at first live birth (7, 9, 10, 16) and nulliparity (9, 16), have largely shown no association with NHL risk, which was also found in an InterLymph pooled analysis (14). Although fewer in number, studies of acute myeloid leukemia (AML) have shown no association with use of HT (17, 18), age at menarche (17) or parity (17, 19), while one study showed a weak inverse association between OC use and risk of AML (17). One study showed a weak inverse association between parity and age at first birth in chronic myelogenous leukemia (CML) (19).…”
