Conventional therapies for cancer diseases, such as chemotherapy, radiotherapy,
immunotherapy, hormonal therapy, and surgical removal, are effective, but they often
come with acute side effects and the development of drug resistance due to their
systemic application. Nanotechnology is one of the options that allows us to reduce the
occurrence of these effects. It enables specific targeting of cancer cells, while the
therapeutic agents used do not affect the surrounding healthy cells. By using various
modifications of nanoparticles, the retention time in tumor tissue can be prolonged,
specificity to tumor cells can be increased, and the nanoparticles can be modified to
achieve controlled release of the therapeutic agent triggered by different stimuli. Further
research in this field can lead to greater optimization of nanoparticles, which may result
in higher effectiveness of cancer treatment and a reduced likelihood of its recurrence in
the future.
