Supplements may help reduce cancer risk through five key pathways:

• Boost immune system function.
• Reduce inflammation.
• Improve insulin sensitivity.
• Support digestion and detoxification.
• Reduce stress-induced hormone imbalances.

It is important to determine that a particular supplement is appropriate for your particular condition and that the dosage and specific brand is appropriate as well.

Typical supplements include but are not limited to:

• Omega-3 fatty acids
• Probiotics
• Polyphenols
• Green tea catechin
• Curcumin
• Resveratrol, which has been postulated to prevent breast cancer by activating tumor suppressor genes and increasing the rate of apoptosis (normal programmed cell death)
• Antioxidants
• Glutathione
• Coenzyme Q10 
• Vitamin D
