Cancer in livestock can affect humans in several ways. Firstly, zoonotic diseases can be transmitted from animals to humans, although cancer itself is not directly transmissible. However, the stress and health decline in livestock can lead to increased susceptibility to other infections that may be zoonotic. Secondly, the use of carcinogenic substances in livestock feed or as veterinary drugs can pose a risk to humans consuming these animal products. Ensuring safe and regulated use of such substances is vital.
