**Understanding Cancer and Its Causes**
Cancer happens when “certain cells in the body begin to divide uncontrollably,” disrupting normal functions and forming tumors. While some causes are unavoidable, many can be prevented through healthy choices.

**Common Triggers of Cancer**
Key risks include “smoking and tobacco use,” “excessive sun and radiation exposure,” and infections like HPV. Poor diet and inactivity also play a major role—“nearly 20% of cancer cases in the U.S. are related to obesity, poor dietary choices, and a sedentary lifestyle.”

**Foods That Increase Cancer Risk**
Some foods may raise cancer risk:
– **Sugary Foods**: Linked to higher insulin and cancer cell growth. “High amounts of sugary foods had an increased risk of pancreatic cancer.”
– **Processed Meats**: Contain preservatives tied to colorectal cancer.
– **Smoked/Pickled Foods**: “Loaded with preservatives, which can damage cells.”
– **White Flour and Hydrogenated Oils**: Promote inflammation and cancer.
– **Microwave Popcorn**: Packaging may contain PFOA, linked to kidney and bladder cancer.
– **Farmed Salmon and Potato Chips**: Contain contaminants like PCBs and acrylamide.

**How to Reduce Risk**
Eat organic produce, quit smoking, exercise regularly, and limit alcohol.

**Final Thoughts**
While “no single food or lifestyle change can guarantee complete cancer prevention,” healthier habits strengthen the body’s defenses.
