Effect of Turmeric (Curcumin) on Cancer Patients: A Comprehensive Review of its Anticancer Mechanisms, Clinical Efficacy, and Potential Therapeutic Applications

Turmeric, and its active constituent curcumin, have been the focus of much attention for their possible anticancer activity. This review will evaluate the effects of turmeric in cancer patients by examining its mechanism of action, clinical activity, and therapeutic efficacy. The main aim is to establish if curcumin is capable of preventing cancer growth and enhancing patient survival. The research strategy entailed an in-depth examination of available preclinical and clinical studies with a focus on the mechanisms of curcumin including antioxidant properties, anti-inflammatory activity, and induction of apoptosis in several cancer cell lines. The review also considered clinical trials evaluating the safety, bioavailability, and therapeutic efficacy of curcumin in cancer patients. Findings reveal that curcumin shows effective anticancer activities, including inhibition of tumor growth, metastasis, and induction of cancer cell apoptosis. Nonetheless, its clinical activity is compromised by its poor bioavailability, which has prompted the discovery of curcumin analogs and delivery systems to improve its therapeutic value. Certain clinical trials show favourable results, including diminished tumor markers and better quality of life among cancer patients. Finally, although curcumin has potential as an adjuvant therapy for cancer treatment, there is a need to enhance its bioavailability and develop standardized treatment modalities.
