Nutraceuticals: A Way Forward for Cancer Treatment

Background: Cancer is a term used for large groups of diseases that are characterized by gene malfunction and cause abnormal cell proliferation that affects different parts of the human body. There are different traditional treatments of cancer, such as radiation and chemotherapy, but they often have significant side effects. Objectives: This review article aims to describe various types of cancer, their treatments, and associated problems. All the treatment methods for cancer are costly. However, the use of nutraceuticals for cancer treatment is cheap. Methodology: Research papers on the therapeutic benefits of nutraceuticals against cancer were collected from various electronic databases, including Google Scholar, PubMed, and Science Direct. The research papers from 2000 to 2024 were collected and analyzed. Results: There are different sources of nutraceuticals, such as animal, plant, and microbial origins. They exhibit antioxidant, anti-cancer and anti-inflammatory effects by enhancing the immune system and inhibiting metastasis. For example, a compound beta-sitosterol derived from plants is very effective against cancer of different body parts. Similarly, sulforaphane present in cruciferous vegetables is very effective in reducing the risk of lung cancer. Additionally, curcumin from turmeric is effective in inhibiting metastatic cancer cells. Conclusion: In recent years, there has been a growing focus on the use of nutraceuticals in cancer treatment. This approach offers promising therapeutic potential with minimal or no side effects, making it a safer alternative to conventional therapies. Nutraceuticals are increasingly being integrated into comprehensive cancer care, complementing standard treatments and enhancing patient outcomes.
