This paper is an integrative review and hypothesis paper based on observation and practical analytical experiments of Dr. Larysa Karaliova. The second part of a review series examines agricultural and industrial-consumption goods such as carcinogens and their contribution to cancer development. Part II focuses on consumer products, food-related exposures, and materials unsuitable for food contact that may contribute to carcinogenic risk. Particular attention is given to dietary, environmental, and industrial factors potentially involved in the development of colorectal (CRC)-, lung cancer addressing its multifactorial nature, including genetic susceptibility, metabolic status, lifestyle, and chronic exposure to exogenous carcinogens. The review analyzes agricultural, industrial, and consumer-product carcinogens, as well as endocrine-disrupting compounds and agents capable of suppressing immune function, as potential contributors to the increasing global incidence of malignant diseases. The analysis is based on peer-reviewed scientific literature, selected analytical experiments, documented real-world cases, and laboratory investigations conducted at the Norwegian Drug Control and Drug Discovery Institute. The relative importance and interaction of diet, environmental conditions, genetic predisposition, and chronic exposure to industrial and agricultural carcinogens are discussed. Comparative observations of cancer occurrence in selected animal species are also considered to support the evaluation of environmental carcinogenic risk.
