Abstract Background Uncontrolled cell proliferation is a major cause of cancer development and progression. Inflammation along with inflammatory mediators and cells play a significant role in cancer. Cancer ranks in second in mortality rates, following cardiac diseases. Phytochemicals from medicinal plants offer a natural and effective approach for treating Inflammation and cancer. Main body of the abstract Animal studies provide evidence that phytochemicals present in food acts as antioxidants, anti-aging molecules, and health promoters, thereby extending lifespan. These natural compounds include quercetin, epicatechin, resveratrol, curcumin, kaempferol, vitamin C and carotenoids. However, clinical data on humans is still awaited. Conventional allopathic cancer therapies often have severe side effects. Recently, drug repurposing has emerged as an alternative strategy offering lower costs, shorter development times and the advantage of existing clinical data. The primary goal of drug repurposing is to discover new uses for approved or experimental drugs. Short conclusion The current review elucidates the side effects of synthetic drugs and the beneficial effects of phytochemicals and non-oncological drugs along with their mechanisms of action for treating cancer. Additionally, it highlights clinical trial data for various cancers focusing on molecular targets. By integrating natural products, drug repurposing and molecular targets, we can develop multifaceted therapies that maximize efficacy and minimize adverse effects. This integrated approach promises more personalized and effective treatments, improving patient outcomes and quality of life. Future research should identifying novel natural compounds, explore repurposing opportunities for existing drugs, and elucidate molecular targets for precise therapy. Additionally, clinical trials should be conducted to validate the efficacy and safety of these combined strategies in cancer patients. Graphical abstract
