 Biomedical research has become increasingly interdisciplinary, requiring a wide range of approaches to better understand human health. In this study, numerical simulations were used to analyze the effects of commercial chemotherapy on cancer cell viability and apoptosis. Experiments were conducted on three different types of cancer cell lines, HCT-116, MDA, MB-231, and HRC-5, which were then compared to each other and to healthy long fibroblasts. The results showed decreased viability and the appearance of late apoptosis in the treated cells, suggesting a correlation between certain parameters. A mathematical model was developed to further explore the behavior of the cancer cells and accurately predict their growth. This approach provides a more comprehensive view of the processes involved in cancer viability and apoptosis, allowing for a deeper understanding of how they are affected by chemotherapy.
