Omega-3 fatty acids, commonly found in fish oil and certain plant-based sources, have been linked to various health benefits, including potential protective effects in cancer care. As someone diagnosed with stage IV rectal cancer, I’ve explored how omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), can influence cancer treatment and outcomes.
Research suggests omega-3s may impact cancer risk, including breast cancer, prostate cancer, colorectal cancer, and gastrointestinal cancers, by reducing inflammation and potentially slowing tumor growth. Throughout my cancer journey, I’ve seen the role omega-3 fatty acids could play in improving overall health and supporting the immune response. This article will dive into the science behind omega-3s, cancer risk, and their possible role in improving cancer outcomes, with insights from my personal experience.

My Diagnosis and Initial Challenges
In 2020, I was diagnosed with stage IV rectal cancer that had metastasized to my liver. A colonoscopy revealed a 6 cm tumor in my rectum, and further scans showed my liver was covered with tumors. My CEA tumor marker was over 2000, and the prognosis was grim. I immediately began chemotherapy and radiation, which came with severe side effects, including fatigue, nausea, and significant weight loss. These challenges made it clear that I needed to find supportive strategies to complement my treatment.
Searching for answers, I turned to research on ways to support my body during cancer treatment. This included understanding the role of nutrition, particularly omega-3 fatty acids, which I learned could play a key role in reducing inflammation and supporting immune health. Integrating these nutrients into my diet became a crucial step in my fight against cancer.

Understanding Omega-3 Fatty Acids
Omega-3 fatty acids are essential fats the body cannot produce independently, requiring them to be obtained through diet or supplements. They are a type of polyunsaturated fatty acid known for their anti-inflammatory effects and significant impact on human health. These fats are vital for maintaining heart health, reducing inflammation, and supporting brain and immune function.
Types of Omega-3 Fatty Acids
- Eicosapentaenoic acid (EPA): Found in cold-water fish like salmon and mackerel, EPA plays a crucial role in reducing inflammation and supporting cardiovascular outcomes.
- Docosahexaenoic acid (DHA): Present in fish oil and DHA-enriched diets, DHA contributes to brain health, membrane composition, and overall survival for cancer patients.
- Alpha-linolenic acid (ALA): A plant-based omega-3 found in flaxseeds, chia seeds, and walnuts, ALA serves as a precursor to EPA and DHA, though its conversion in the body is limited.
Research shows omega-3s provide wide-ranging benefits, from lowering cholesterol to potentially improving cancer outcomes. These fatty acids may reduce cancer-related inflammation, slow tumor growth, and support overall health in cancer patients, including those with breast cancer, colorectal cancer, and prostate cancer.

The Connection Between Omega-3s and Cancer
Scientific research has shown that omega-3 fatty acids play a promising role in cancer care. Studies suggest they may reduce cancer risk, slow tumor growth, and improve cancer-related outcomes. The anti-inflammatory effects of omega-3s are particularly relevant for conditions like breast cancer, prostate cancer, and colorectal cancer. For cancer survivors, omega-3s have also been linked to better overall survival and reduced cancer mortality.
Omega-3s can lower inflammation by influencing metabolic pathways and improving the immune response. Chronic inflammation is a known risk factor for cancer development, contributing to tumor growth and the spread of cancer cells. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have been shown to decrease inflammatory markers, improve red blood cell membrane composition, and support cardiovascular health, which is crucial for cancer patients.
Key studies and expert opinions influenced my decision to incorporate omega-3s. A recent systematic review highlighted the protective effects of omega-3s on cancer outcomes, including their ability to lower cancer incidence in high-risk individuals. Clinical trials and cohort studies also pointed to their potential to reduce gastrointestinal cancer risks and improve cancer treatment results. These findings and discussions with healthcare professionals gave me confidence in making omega-3s part of my routine.
Deciding to Supplement with Omega-3s
As I researched supportive strategies for cancer care, I found compelling evidence that omega-3s could reduce cancer-related inflammation and improve immune function. Meta-analyses and clinical trials indicated that fish oil supplements, rich in EPA and DHA, might slow tumor growth and improve cancer-related outcomes. The link between omega-3s and reduced risks of breast, prostate, and colorectal cancer further solidified my decision.
I consulted with healthcare professionals to ensure omega-3 supplementation was safe and effective for my condition. They emphasized the importance of the correct dosage to avoid adverse effects, such as bleeding risks or interactions with cancer medications. These discussions guided me to select high-quality fish oil supplements and include dietary sources like cold-water fish to support my overall health.

Incorporating Omega-3s into My Routine
I’ve structured my daily routine to maximize the benefits of omega-3 fatty acids. Here's how I incorporate them into my schedule:
Time | Activity |
Morning | 10:00 AM - Morning supplements, including omega-3s, and making 1000 cc of green tea.
10:30 AM - Half cup of kefir for gut health.
10:50 AM - Black coffee with 10 cc MCT C8 oil and a small piece of organic grass-fed butter. |
Lunch | 12:00 PM - 30 cc olive oil with supplements, including omega-3s, and a meal with sauerkraut. |
Afternoon | 4:00 PM - Exercise to support overall health. |
Evening | 7:00 PM - 30 cc olive oil with supplements, including omega-3s, and dinner.
11:00 PM - Evening supplements. |
This schedule ensures I get consistent omega-3 intake throughout the day, supporting my immune system and overall health while complementing my cancer treatment regimen.
Benefits of Omega-3s During Cancer Treatment
Incorporating omega-3 fatty acids into my routine during cancer treatment provided several noticeable benefits. These essential fats improved my physical and mental health while complementing my ongoing medical treatments.
How Did Omega-3s Impact My Health?
- Reduced inflammation and improved immune response: Omega-3s, particularly EPA and DHA, helped lower chronic inflammation, a key factor in cancer development. These fatty acids also supported my immune response, which is critical during chemotherapy and recovery.
- Enhanced mental clarity and mood stabilization: Omega-3s improved my mental clarity, reducing the "chemo brain" fog and stabilizing my mood. They have been studied for their role in managing major depressive disorder and cognitive health.
- Potential slowing of cancer progression and better treatment outcomes: Studies suggest omega-3s may slow tumor growth and improve overall survival rates. By integrating these fatty acids into my regimen, I noticed better resilience during treatment and improved cancer-related outcomes.
Advice for Others
Omega-3 fatty acids offer significant potential for cancer patients, but their use should be approached thoughtfully. My experience taught me that careful planning and regular monitoring are essential to reap their benefits safely.
