A comparative study of urinary oestrogens in the cancer of breast and prostate

Abstract

Estrogens have been estimated in 24 hr urine of breast cancer women during premenopausal and postmenopausal phases, before and after the surgery. There was an increased excretion of one of the fractions of estrogens, i.e. estriol as compared to the normals. There was not much change in the other two fractions, i.e. estrone and estradiol. With the advancement of the disease, there was an increased excretion of the urinary estrogens. Estrogen levels have also been observed in the patients suffering from carcinoma of prostate and a decrease in the urinary estrogen level was observed.
