i would like to express my gratitude to liana Oganesyan, a junior researcher at the chemotherapy department Vachaganovne. I have been undergoing chemotherapy for 1.5 years. The health situation is constantly changing. Liana Vachaganovna is always very attentive to all changes in the state of health. Promptly, and most importantly very accurately changes the course of treatment. I always feel it immediately on my health. This indicates her high level of knowledge and professionalism! Many thanks to her. God grant that all doctors were like that!
