Typic adverse reactions from chemotherapy in cancer patients

The issues of chemotherapy remain the most difficult, because it is perhaps practically impossible to carry out drug therapy correctly, observing the main ethical principle of a doctor – do no harm. One of the main principles of chemotherapy is based on stopping cell replication, destroying their growth and vital activity, which is undoubtedly associated with an impact on healthy cells, the life cycle of which, depending on histological characteristics, may vary from several days to several weeks and months, which, in any case, implies an inevitable damaging effect on various organ and tissue systems. The more aggressive the chemotherapy, the more complex the combinations used, the greater the damaging consequences. Knowing the most vulnerable targets, the mechanisms of their development, it is possible to correct the most dangerous risks and prevent undesirable consequences. Accumulated experience with chemotherapy allows us to predict the most dangerous risks arising both during therapy, from chronic diseases that reduce quality of life, and after its completion, including delayed effects leading to death due to hidden, dangerous complications. Properly selected and timely complication prevention, comprehensive diagnostics of markers of pathological changes in vital organs, adjustments to therapy, and other measures are the fundamental principles of effective therapy. The main recommendations are regular visits to specialized physicians in related fields and patient compliance. Treatment for cancer patients does not end with their discharge from the hospital. Lifelong follow-up is required for patients who have completed therapy with a positive outcome.
