Abstract: Deadly disease cancer has many types; among them, lung cancer is responsible for the
highest number of cancer mortality. Existing therapies as well as drugs for treating lung cancer are
not effective and are often associated with innumerable side effects and toxicities. For these reasons,
researchers have been working on developing novel anti-cancer medicines from plants and
other natural sources that have a high safety profile. Natural flavonoids are a polyphenolic group of
phytochemicals extracted from plants and other plant-derived compounds. Natural flavonoids are
gaining popularity due to their unique and priceless medicinal properties, including anticancer
properties. Several researchers have already declared that flavonoids possess the ability to treat different
cancers, particularly lung cancer. The bioactivity of natural flavonoids is mainly due to their
structural diversity. Natural flavonoids fight against lung cancer by regulating redox homeostasis,
upregulating apoptosis, pro-apoptotic factors, and survival genes, arresting cell cycle progression,
autophagy, reducing cell proliferation and invasiveness, maintaining inflammation response, downregulating
anti-apoptotic factors, and targeting lung cancer signaling pathways. Flavonoids can act
alone or synergistically with other agents to treat lung cancer. Due to these reasons, it is possible to
use natural flavonoids as pharmaceutical leads to prevent and treat lung cancer.
