Animal models have been used since early times to understand several diseases. Cancer is one of the most frequent diseases worldwide, accounting for approximately 10 million deaths in 2020. The most common cancers in 2020 were: breast, lung, colon and rectum, prostate, skin, and stomach. Cancer arises from the conversion of normal cells into initiated cells as a result of the interaction between intrinsic and extrinsic factors, namely physical agents, chemical agents and biological agents. In vivo studies are essential to improve and discover new strategies to prevent and treat cancer more effectively, improving patients’ lifespan and quality of life.
This presentation intends to describe the rodent models available for cancer study, highlighting their advantages and disadvantages, as well as their potential in the evaluation of several drugs and natural compounds for cancer treatment.
