Cancer remains one of the leading causes of death worldwide, prompting ongoing research into potential treatments. In 2021, scientists discovered that a specific type of collagen might help keep dormant cancer cells from becoming active, offering new possibilities for cancer treatment.

The Role of Collagen in Cancer Prevention

A study published in Nature Cancer found that in mice, dormant cancer cells were surrounded by higher amounts of a specific collagen type than active cancer cells. This collagen, known as type III collagen, is a key protein in connective tissue.

Researchers also analyzed patients with head and neck cancer and observed a similar pattern. Tumors with lower amounts of type III collagen were more likely to spread to the lymph nodes, suggesting that this collagen helps keep cancer cells inactive. When collagen levels drop, the cancer becomes active again.

How It Works

In mouse models, researchers observed that type III collagen levels gradually decreased over time. When this happened, the cancer cells became active. They also found that the collagen altered the body’s chemistry, maintaining dormancy through a process called the signaling pathway. When this process was disrupted, the cancer reactivated.

Implications for Cancer Treatment

These findings could help oncologists predict whether a cancer is likely to spread. Additionally, researchers found that replacing tumors with scaffolds made of this collagen could prevent cancer from growing and spreading. Using specialized microscopy, they monitored cancer cells in real time.

“We want to film them in real time so we can understand their process and their behavior,” said study senior author Jose Javier Bravo-Cordero. He noted that tumors with decreasing collagen expression might be more likely to spread.

Boosting Collagen Intake

Collagen plays a crucial role in the body, and increasing collagen intake may have potential health benefits. Some ways to boost collagen naturally include:

• Eating collagen-rich foods like bone broth, chicken skin, and fish skin.
• Consuming protein sources such as meat, fish, eggs, and dairy to support collagen production.
• Taking collagen supplements in powder, capsule, or gummy form.
• Eating vitamin C-rich foods like citrus fruits, strawberries, and bell peppers, as vitamin C aids collagen synthesis.
• Incorporating amino acid-rich foods like lean meats, fish, and eggs.
• Avoiding excessive sun exposure, as UV radiation can break down collagen.
• Reducing sugar intake, which can damage collagen fibers.
• Not smoking, as smoking lowers collagen production and accelerates aging.

Choosing the Right Collagen Supplement

When selecting a collagen supplement, consider the following:

• Type of collagen: Type I and III benefit skin, hair, and nails, while Type II supports joints.
• Source: Collagen can come from bovine (cow), porcine (pig), marine (fish), or chicken sources.
• Hydrolyzed form: Hydrolyzed collagen (collagen peptides) is easier for the body to absorb.
• Quality and purity: Look for products from high-quality, pasture-raised, or wild-caught sources.
• Additives: Choose products with minimal additives or artificial sweeteners.
• Brand reputation: Check reviews and ratings for customer satisfaction.
• Price and return policy: Compare costs and ensure a refund option is available.

More Research Needed

In mice, scientists successfully forced cancer cells into a dormant state about 80% of the time. While promising, it remains unclear if the same approach will work in humans, as human cancers are more complex.

Though further studies are needed before this discovery can be used in regular cancer treatments, these findings offer hope for new strategies to prevent cancer from spreading—an exciting possibility for those affected by the disease.
