Adjuvant treatment protocols in breast cancer are currently based on the biological characteristics of the primary tumour, which in most cases has been removed surgically. Considering tumour heterogeneity in met...

breast conservation surgery combined with radiation therapy is now an accepted option for the treatment of early breast cancer. so we decided to evaluate the results of such treatment in our first group of patients treated by this method. from 1992 to 1996 , one hundred patients with stage i and ii breast cancer treated with breast conservative surgery (lumpectomy or quadrantectomy). were irrad...
