Risk factors in breast cancer: are they important, are they the same in pre- and post-menopausal breast cancer patients?

The information derived from the mammographic history questionnaires of 450 breast cancer patients was collated and separated, comparing 332 post-menopausal and 118 pre-menopausal breast cancer patients. Our observations confirm the importance of risk factors in the development of breast cancer and show the similarity in the incidence of certain risk factors among pre- and post-menopausal breast cancer patients.
