Gonadal and hypophyseal hormones were investigated in 15 males with breast cancer and 15 tumour referents, on average 1 month postoperatively. Plasma prolactin was found to be significantly more often elevated in men with breast cancer compared with referents (p <0.005). Another group of men with breast cancer disclosed a tendency for lower S-FSH levels compared with the referents (p <0.01). No significant difference was seen between cases and referents regarding S-LH, p-estradiol or p-testosterone. The size of the primary breast tumour was correlated with a higher prolactin level. The findings lend support to a theory implicating prolactin and possibly prolactinomas as a risk factor for the disease in males.
