This study aimed to evaluate DNA damage in patients with breast cancer before treatment (background) and after chemotherapy (QT) and radiotherapy (RT) treatment using the Comet assay in peripheral blood and the micronucleus test in buccal cells. We also evaluated repair of DNA damage after the end of RT, as well as the response of patient’s cells before treatment with an oxidizing agent (H2O2; challenge assay). Fifty women with a mammographic diagnosis negative for cancer (control group) and 100 women with a diagnosis of breast cancer (followed up during the treatment) were involved in this study. The significant DNA damage was observed by increasing in the index and frequency of damage along with the increasing of the frequency of micronuclei in peripheral blood and cells of the buccal mucosa, respectively. Despite the variability of the responses of breast cancer patients, the individuals presented lesions on the DNA, detected by the Comet assay and micronucleus Test, from the diagnosis until the end of the oncological treatment and were more susceptible to oxidative stress. We can conclude that the damages were due to clastogenic and/or aneugenic effects related to the neoplasia itself and that they increased, especially after RT.

Water is one of the most precious natural resources of the earth, without which the living beings cannot survive. Water is important for the sustenance of human civilization. Man uses water for many purposes like drinking, cleaning, washing, bathing, heating, rearing cattle, and farming. Mankind, for the bettering of themselves and society, advanced towards industries and industrial products. But this progress towards industrialization not only utilizes huge amounts of fresh water, but returns water to the environment with pollutants, which changes its natural quality. Thus, mankind is heading towards misery, instead of comfort. Effective measures need to be taken to prevent, minimize, and control water pollution before it becomes too late.
