The frequency of micronucleated binucleate lymphocyte (MNBNC) was determined in the peripheral blood lymphocytes of patients suffering from various types of cancer before the onset of radiation treatment, middle (mid-) of the treatment and after completion of the treatment (post-treatment). The frequency of micronuclei increased significantly in the pretreatment sample of cancer patients when compared with the normal untreated healthy volunteers. During the middle of the radiotherapy an approximate two or >two-fold increase was observed in the micronuclei frequency in most of the patients when compared with the concurrent pretreatment samples. Immediately after the completion of treatment, the frequency of micronuclei further increased, and this increase was significantly higher than that of pretreatment and mid-treatment samples. Out of 27 patients analyzed, only nine patients did not have any history of smoking, tobacco chewing or alcohol consumption, while the remaining 18 patients had a history of either smoking, tobacco chewing or alcohol consumption or combination of two or all habits at the time of blood collection.
