For hormone-related cancers, birth order and age at menarche had the most influence on this relation, while maternal proteinuria, birth order and own parity had the most effect on non-hormonal cancer risk. Birth length and cancer risk Univariate analysis A positive and statistically significant trend was found between birth length and all cancers combined (P = 0.007), and non- hormonal cancers (P = 0.011), while a marginally significant trend was found for combined hormone-related cancers and colon cancer (P = 0.058), adjusted for gestational age.
