Abstract
Background and Aim: Breast cancer has been reported to increase globally imposing a public
health in both developing and developed societies. The association of carotenoids and cancer
development has been demonstrated in a number of clinical, in vivo, and in vitro studies. In this
study we reviewed the relationship between carotenoids and breast cancer.
Method: A review of the literature was conducted using databases such as PubMed, Scopus, and
Web of Science, covering studies published between 2000 and 2024. Experimental and clinical
studies focusing on association of carotenoids and breast cancer were included. Mechanistic
studies exploring the biological action of carotenoids on cancer cells were also reviewed.
Results: Studies have found that circulating carotenoids may be linked to breast cancer risk. It has
been suggested that high consumption of carotenoids could reduce the risk of premenopausal
breast cancer. Significant associations have been reported between plasma carotenoids, retinol,
tocopherols, and postmenopausal breast cancer risk. An inverse association has been observed
between plasma concentrations of β-cryptoxanthin and β-carotene with overall and breast cancer
risk. We have shown that deinoxanthin, a carotenoid extract, can induce apoptosis in breast cancer
cells by decreasing of anti-apoptotic BCL2 gene expression level and also increasing of BAX gene
expression levels.
Conclusion: Overall, the findings of experimental and clinical studies reveal the potential role of
carotenoids in breast cancer risk, with some studies suggesting a protective effect. Further research
is required to reveal the exact mechanism behind the relationship between carotenoids and breast
cancer
