What is fish oil and its connection with cancer?
Fish oil is a natural supplement derived from oily fish like salmon, mackerel, and sardines. It is loaded with omega-3s – principally EPA (Eicosatetraenoic Acid) and DHA (Docosahexaenoic Acid). They help to suppress inflammation, boost immunity, and support the heart. However, in cancer cases, some studies have suggested that certain qualities of fish oil can treat cancer.
It is this anti-inflammatory and cell-regeneration ability that made fish oil so popular with cancer patients. But does fish oil cure cancer? Illusions and facts will tell us how to answer this.
What is the effect of fish oil on cancer?
1. How does fish oil work in the body?
The omega-3 fatty acids in fish oil and cancer block inflammatory pathways after entering the body. When inflammation subsides, cells get a chance to regenerate. This process is very important in fish oil and cancer patients because inflammation can accelerate tumor growth.
2. What do scientific studies say?
- Research: According to a study, regular use of fish oil and cancer therapy slows down the growth of breast cancer cells.
- Anti-tumor Effect: Omega-3 fatty acids reduce the size of tumors in some cancers, such as colon cancer.
- Use in combination with chemotherapy: Fish oil and cancer therapy may reduce the side effects of chemotherapy, such as nausea and fatigue.
Therefore, fish oil and cancer treatment is considered a supplementary therapy that may support cancer treatment.
Benefits of Fish Oil in Cancer Treatment
1. Increases the effectiveness of chemotherapy
Fish oil, rich in omega-3 fatty acids, can boost the effectiveness of chemotherapy medications. They direct the drugs to the cancer cells.
2. Lowers the side effects of cancer treatments.
Fish oil can minimize the side effects of cancer therapy, including nausea, fatigue, and weight gain.
3. Strengthens the immune system
In cancer, one should keep an immune system healthy. Fish oil shields the immune cells.
4. Improves mental health

Facts About Fish Oil and Cancer
1. Fish Oil is a Supplement, Not a Cure
Fish oil cannot be considered a replacement for cancer treatment. It is a supplement that can support your existing treatment plan. It does not shrink tumors, but it can make chemotherapy more effective and reduce side effects.
2. Quality and Purity Matter
There are many fish oil supplements available in the market, but not all are effective. High-quality fish oil that is third-party tested should be taken. Fish oils containing contaminants such as mercury or heavy metals can cause problems for cancer patients.
3. It is important to take advice from a doctor
It is important to take advice from an oncologist or doctor before including fish oil in your treatment plan. You can get the best results with proper guidance regarding dosage and timing.
4. Dosage of Fish Oil
For general health, 1000 mg to 2000 mg daily fish oil is sufficient, but for cancer patients, this dosage can differ. Decide the dosage only after discussing it with the doctor.
5. Plant-Based Omega-3 Option
If you are a vegetarian, then omega-3 can also be obtained from plant-based sources like flaxseed oil and chia seeds. However, it cannot provide the full benefits of DHA and EPA, which are available only from fish oil.
Case Studies and Research Data
Case Study 1: Effect of Fish Oil on Breast Cancer Patients
In a study, breast cancer patients were given fish oil along with chemotherapy. The result was that those who consumed fish oil had slower tumor growth and fewer side effects such as fatigue and hair loss.
Data:
- Patients without fish oil: 25% experienced severe fatigue.
- Patients with fish oil: Only 10% felt severe fatigue.
Case Study 2: Colon Cancer and Inflammation Reduction
In a trial on colon cancer patients, regular use of fish oil showed a significant decrease in inflammation markers. Reduction in inflammation also slowed tumor progression.
Data:
- Inflammatory markers: 30% reduction in patients using fish oil.
- Tumor growth rate: slowed down by 15% in the fish oil group.
These studies suggest that fish oil may have a supportive role in cancer treatment.
