Why Cancer Rates are Rising

Cancer treatment has undergone a revolutionary shift with the rise of immunotherapy, a treatment that leverages the body’s own immune system to target and destroy cancer cells. While traditional treatments like chemotherapy and radiation have been the cornerstone of cancer care, their limitations—including immune suppression, severe side effects, and inconsistent efficacy—have spurred the search for alternative approaches. Among these, immunotherapy has emerged as a powerful tool, offering targeted treatment with the potential for long-term remission. But its success is far from guaranteed.

Recent research has uncovered a critical factor influencing cancer treatment outcomes: the gut microbiome. The relationship between gut health and immunity is well-documented, with growing evidence showing that microbiome composition can impact cancer progression and the efficacy of immunotherapies.

Additionally, the rising incidence of cancer in young people has prompted deeper investigations into environmental and lifestyle factors contributing to immune system dysfunction.


The Role of Immunotherapy in Cancer Treatment

For decades, chemotherapy and radiation have remained the primary treatment strategies for most cancers. However, these methods often come with significant drawbacks, including systemic toxicity, immune suppression, and severe side effects that diminish quality of life. In contrast, immunotherapy works by enhancing the immune system’s ability to recognize and eliminate cancer cells more effectively.

Checkpoint inhibitors, such as anti-PD-1 and anti-CTLA-4 therapies, have revolutionized the treatment of cancers like melanoma and lung cancer by preventing tumor cells from evading immune detection. However, not all patients respond equally to these treatments, and in many cases, immunotherapy’s effectiveness is closely linked to the overall health of the immune system—including its interactions with gut bacteria.


Scientific Evidence from Cancer Studies

Clinical studies have highlighted the potential role of mycolicibacteria in improving patient outcomes. A trial involving lung cancer patients found that supplementation with Mycobacterium vaccae significantly improved quality of lifewithout impacting survival. Additionally, research into melanoma and pancreatic cancer has revealed that patients with stronger immune resilience—often linked to gut health—exhibited better treatment responses. Since immune strength plays such a critical role in treatment outcomes, it raises an important question: could improving gut health be a missing piece in optimizing cancer care? The connection between the microbiome and immunity is becoming increasingly clear, setting the stage for exploring how gut health interventions could enhance cancer treatment success.


How Microbiome Health Affects Cancer Risk

The gut microbiome is the largest immune-regulating organ in the body, playing a crucial role in training immune cells to detect and attack abnormal cells. A well-balanced microbiome helps prevent immune exhaustion, reduces chronic inflammation, and improves overall resilience against diseases, including cancer.

One of the most striking examples of the gut-immune connection is the impact of fecal microbiota transplants (FMT)on cancer treatment outcomes. Studies have shown that patients receiving fecal transplants from individuals with robust microbiomes experienced improved responses to immunotherapy. In melanoma patients, FMT from responders to non-responders increased the latter group’s immune activity and likelihood of benefiting from treatment.


Why Are Cancer Rates Rising in Young Adults?

Cancer rates are rising in people under 50, with colorectal cancer seeing one of the most dramatic increases. This shift is alarming because cancer was once considered a disease primarily affecting older adults with genetic risk. Researchers are now looking into what’s driving this trend, focusing on changes in lifestyle, increased exposure to environmental toxins, and the disruption of gut health, and have identified some possible causes:

  • Diet & Nutrition: The rise in ultra-processed food consumption and low-fiber diets has led to widespread microbiome imbalances, contributing to chronic inflammation.

  • Environmental Toxins: Exposure to microplastics, air pollution, and endocrine disruptors has been linked to immune suppression and increased cancer risk.

  • Sedentary Lifestyles: Reduced physical activity exacerbates inflammation and weakens immune surveillance.

  • Gut Microbiome Disruption: Early and frequent antibiotic use, poor dietary habits, and urbanization have weakened the gut microbiome, making younger individuals more susceptible to chronic diseases.

But these factors don’t operate independently—they are all connected through chronic inflammation. When the immune system is constantly battling inflammation, it loses its ability to effectively detect and eliminate cancerous cells, and over time, this dysfunction weakens the body's natural defenses, increasing the risk of early-onset cancers.


What Can immy Do For You

While we can’t claim to know what will cure cancer forever, we do know that immune resilience plays a crucial role in overall health. The immune system and microbiome are deeply connected, influencing inflammation, disease progression, and even how well the body responds to treatment. Given that chronic inflammation weakens immune strength, supporting gut and immune health may be an important step in maintaining long-term resilience.

immy, with its unique mycolicibacteria formulation, is designed to help balance immune response and promote gut health. While research continues to explore the link between microbiome support and cancer outcomes, what’s clear is that strengthening the body’s natural defenses is a step worth taking for overall well-being. Taking care of your immune system today may help you stay stronger and more resilient in the future.
