Current issues of 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.
