background: radiotherapy plays an important role in the management of most malignant and many benign primary central nervous system (cns) tumors. radiotherapy affects both tumor cells and uninvolved normal cells; so, it is important to estimate absorbed dose to organs at risk in this kind of treatment. the aim of this study was to determine the absorbed dose to chiasma, lens, optic nerve, retin...

background : the association of the mobile phone use and risk of brain tumor remains controversial among radiationepidemiologists. methods : we hypothesized if an association between brain tumor and mobile phone use exists, this association will be manifested as a cohort effect (as a proxy of association between mobile phone use and brain tumor) in the incidence rates of brain tumor during the ...

the brain is a rare site for metastasis in most extracranial pediatric solid tumors, including wilm’s tumor. outcome for these patients are generally dismal. very few cases have been reported to have good survival even after therapy. this paper reports a case of stage iv wilm’s tumor with lung metastases in a patient who developed a solitary brain metastasis five months after completion of chem...
