Role of Fish Oil in Reducing Cancer Growth (study)

@miked77
I was not aware of the connection of Fish Oil with PC. But the whole picture of someone watching their diet an taking healthy supplements could be association with better PC statistics with higher healthier living.

I have taken Fish Oil for about 20 years. I take Cold Water Salmon Oil. My heart failure recommended it to me to reduce triglycerides. It cut my triglycerides by 50%. So I am a pro Fish Oil even if did not have a good affect on PC. I hope it does as was diagnosed with PC back in 2023 and had 30 rounds of proton radiation.

Sounds like something worth trying. For best effects, be sure to replicate their full diet:
> high omega-3
> low omega-6
> comprising
—> 30% Kcal from fat,
—> 15% Kcal from protein, and
—> 65% Kcal from carbohydrates
—> also 4 fish oil capsules per day

Thanks for posting this info : ) !

JC - How much are you taking every day ? : ) I need to lower my triglycerides.

Regarding PC - maybe it did help , maybe it kept it at bay for those 20 years. Your Decipher was pretty low at the end regardless of gleason score : ) and it stayed localized : ))) One never knows, I guess ; ).

Thanks Brian for the link : ))) and yes, I think that multifaceted approach is a the key.

@brianjarvis This appears to be the link to the actual study that was published in March 2025 Journal of Clinical Oncology. Thanks for the link.

in question in the exclusion criteria was avoidance of Lycopene. I wonder why?

My heart failure doctor recommended I take 2,000 mg twice a day. I can't remember the exact date he recommended that but probably at least 15 years ago. It usually comes in 1K soft gels so I take two twice a day.

For me, and clarify just saying for me, I did see a 50% reduction in my triglycerides'. I started taking a statin (prescription) in 2015 to help with LDL and plaque found during a heart Catherization. That too made a dramatic difference in my LDL.

Some cheap brands use fish farms not open cold water which I was told was best. My wife was advised to take it also and at first was on a prescribed version. But her PCP said she could take the OTC brand just stay with a known brand manufacturer.

Yes I agree. All those years I was taking before PC diagnosis it could have been helping keep it at bay.

I am very careful though on my supplements. I talk to both my heart failure, and electrophysiologist about taking my supplements and sometimes have been told not to take this or that.

Good result after one year, but they really need a longer study. If you read further in the results, there was NO difference in PSA, tumor length or grade group in the pre and post biopsies done 1 year apart.
So yes, one tumor marker decreased by 15% but the overall picture, not so much. We really need to know what happens after 3-5 years; do the results stay the same, get better in terms of tumor shrinkage and PSA score - or do they reverse and show less improvement?
It would be fantastic if men on AS could stay there indefinitely with the simple addition of fish oil and a better diet. One can only hope! Thanks for the article,

@miked77 Some studies suggest a potential link between high lycopene intake and a reduced risk of developing prostate cancer (but studies have been mixed on this conclusion).

In this particular study, they wisely chose to exclude this possible confounder.

@brianjarvis Thanks for the info. I just checked my Centrum for Men vitamins and it contains no lycopene.
