Cancer is a complex illness that arises from changes in the DNA within our cells. It occurs as a result of mutations that alter cell division, cellular growth, and the ability of cells to spread and invade other tissues in our body.

While there are many factors that can contribute to the development of cancer, there is one factor in particular that is gaining increasing attention from researchers- inflammation.

What is inflammation?

Inflammation is a natural response that occurs when our body detects a harmful stimulus, such as a virus, bacterium, or injury.

It is a complex process that involves the release of signaling molecules, immune cells, and other mediators that help to protect and heal our body. For example, when we cut our finger, inflammation brings in white blood cells and platelets to stop bleeding and fight infections, while also triggering the formation of new skin cells to heal the wound.

How does inflammation contribute to cancer?

While inflammation is a helpful response in the short-term, when it becomes chronic, it can lead to tissue damage, scarring, and mutations in the DNA within our cells.

For example, inflammatory conditions such as inflammatory bowel disease (IBD), arthritis, and hepatitis have all been associated with an increased risk of cancer. In addition, lifestyle factors such as obesity, smoking, and alcohol consumption are also known to cause chronic inflammation and increase cancer risk.

How does cancer use inflammation to grow?

Cancer cells have the ability to use the inflammatory response to their advantage by secreting their own inflammatory mediators.

These mediators can recruit immune cells to the site of the tumor, promote angiogenesis (the formation of new blood vessels), and suppress the immune response that would normally attack the cancer cells. In addition, cancer cells can also hijack the normal cellular pathways that regulate inflammation, allowing them to create an environment that is conducive to their own growth and survival.

What are some ways to reduce inflammation and cancer risk?

Reducing chronic inflammation can be an effective way to reduce cancer risk. Here are a few steps you can take:.

1. Maintain a healthy weight

Obesity is a major risk factor for chronic inflammation, and can increase the risk of several types of cancer. Maintaining a healthy weight through a balanced diet and exercise can help to reduce inflammation and lower cancer risk.

2. Eat anti-inflammatory foods

Foods that are high in antioxidants, omega-3 fatty acids, and other anti-inflammatory compounds can help to reduce inflammation in the body. Some examples include: berries, leafy greens, tomatoes, fatty fish, nuts, and seeds.

3. Avoid pro-inflammatory foods

Foods that are high in sugar, refined carbohydrates, and saturated fat can promote inflammation in the body. Limiting intake of processed foods and focusing on whole, minimally processed foods can help to reduce inflammation and lower cancer risk.

4. Exercise regularly

Regular exercise has been shown to reduce chronic inflammation in the body, and can lower the risk of several types of cancer. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.

5. Manage stress

Chronic stress can increase inflammation in the body, and has been linked to an increased risk of several types of cancer.

Finding healthy ways to manage stress, such as meditation, yoga, or deep breathing, can help to reduce inflammation and lower cancer risk.

6. Quit smoking

Smoking is a major risk factor for several types of cancer and can increase inflammation in the body. Quitting smoking can help to reduce inflammation and lower cancer risk.

Conclusion

Inflammation is a natural response that can be helpful in the short-term, but when it becomes chronic, it can increase the risk of cancer.

Cancer cells can use the inflammatory response to their advantage by secreting their own mediators and hijacking the normal cellular pathways that regulate inflammation. Reducing chronic inflammation through lifestyle interventions such as maintaining a healthy weight, eating anti-inflammatory foods, exercising regularly, managing stress, and quitting smoking can help to lower cancer risk.
