Impurities can influence cancer development through several mechanisms. Chemical impurities, for example, can act as carcinogens, initiating or promoting the transformation of normal cells into cancerous ones. Certain environmental impurities, such as pollutants or toxins, have been linked to increased risk of specific cancers. These substances may induce genetic mutations, disrupt cellular processes, or cause chronic inflammation, all of which can lead to carcinogenesis.
