I posted a few studies on the anti-tumor effects of saturated fatty acids (SFA). However, they were all in-vitro studies and as such do not carry as much weight as studies on living organisms. In addition, a few of my doctor friends I have discussed this with kept insisting that even if SFA were to have an anti-tumor effects in vivo they are probably cytotoxic to normal tissue and cannot be clinically used. The fact that most approved cancer drugs are also cytotoxic if of course conveniently ignored.
Anyways, this study below was done on both mice and rats and as such carries even more weight as it spans different species. As you can see, a relative low dose of caprylic acid (HED was 5g - 10g, used just twice in a single day) was able to obliterate most of the studied tumors if they were small/medium in size, and the ones that it did not obliterate were greatly inhibited. Perhaps just as importantly, caprilyc acid did not have any toxic effects on normal tissues. Coconut oil contains 6%-10% caprylic acid, so that is probably the best dietary source to replicate the design of this study.

Oncolytic effects of fatty acids in mice and rats. - PubMed - NCBI
"...Intrahepatic implants of M114 carcinoma in B6D2F1/J mice were treated by intraperitoneal injection of 30 mg sodium caprylate (octanoate), and implants of Nb2 lymphoma in Nb rats were treated with 300 mg tricaprylin orally. After 4-11 h extensive damage to tumor cells was evident microscopically whereas liver cells were unaffected. Tumors in mice treated once daily from the fourth to eighth day after implantation were obliterated. Subcutaneous implants of hepatoma Nb10L in Nb rats treated transdermally with a caprylic acid preparation underwent similar damage. Fatty acids can cause lysis of tumor cells with little damage to normal tissue in certain situations. This action is not related to mitotic activity and represents a novel mode of antitumor action."

"...Figure 5 is the remains of mouse tumor M I I 4, which was treated daily from days 4-8 after implantation. Tumor tissue has been destroyed and replaced by scar tissue."

"...Rat hepatoma NblOL implanted under the skin -4 wk earlier was treated with caprylic acid ointment twice daily for 2 d. Tumors shrank and became soft; tumors of -6 mm diameter were reduced by about half. Histological examination showed a picture similar to that ofthe liver tumors, with areas of intense damage and areas that were unaffected. Smaller tumors could be obliterated. Larger tumors allowed to grow again after treatment did so, being retarded in proportion to the degree of reduction in size by the treatment."

"...Caprylic acid was chosen because it rapidly enters the liver via the portal system after oral ingestion of the triacylglyceride, and it has no fate other than oxidation (1 1); also, it penetrates skin more readily than do longer-chain FAs (12). It has been tested as the free acid, the sodium salt, and as the triacylglyceride; the cellular effects on various tumor cells are the same in all cases. In the liver extensive damage to tumor cells can be seen hours after administration. In subcutaneous growths similar damage can be achieved by transdermal application. In both cases there is a certain amount of tumor damaged with each application; in both locations it is possible to obliterate small tumors."


In addition, here is another in vitro study showing robust inhibiting effects of caprylic, capric and caproc acids against breast, skin (melanoma) and brain cancers. The concentration used was in the range 0.6mM/: up to 3mM/L, which means in vivo human doses of 6g - 20g would be needed to replicate these effects. Quite doable with a 1-3 tbsp. of MCT.

Anticarcinogenic properties of medium chain fatty acids on human colorectal, skin and breast cancer cells in vitro. - PubMed - NCBI
"...Additionally, real-time quantitative PCR (RT-qPCR) was performed to elucidate the potential anti-cancer mechanisms of the three fatty acids under investigation. Capric, caprylic and caproic acids reduced cancer cell viability by 70% to 90% (p < 0.05) compared to controls. RT-qPCR data indicated that these natural molecules produced anticancer effects by down-regulating cell cycle regulatory genes and up-regulating genes involved in apoptosis. Future research will validate the anticancer effect of these fatty acids in an appropriate in vivo model."

"...This study investigated the ability of capric, caprylic or caproic acid to inhibit the proliferation of human colorectal carcinoma, human skin epidermoid carcinoma and human mammary gland adenocarcinoma cells. The cancer cells were treated with various concentrations of fatty acids for 48 h, and their effect on cell viability was monitored. The concentrations of fatty acids used in the growth inhibition assay were selected based on preliminary experiments that were performed using a wide range of concentrations for each fatty acid. As indicated before, all three fatty acids significantly (p < 0.05) inhibited the cell proliferation of human colorectal carcinoma, skin epidermoid carcinoma and mammary gland adenocarcinoma cells (Figure 1A–C). The growth inhibitory effect was concentration dependent for all three fatty acids, with the highest concentration producing the greatest anticancer effect. It was also observed that capric acid exhibited the strongest inhibitory effect, especially on colon and skin cancer cells, followed by caprylic and caproic acids. Although the reason behind the differences in their efficacies is not known, the anticancer efficacy generally diminished with the decrease in the number carbon atoms present in the fatty acid; the most effective capric acid contains the highest number of carbons [10], followed by eight and six carbons in caprylic and caproic acids, respectively."

We may as well. Peat already mentioned this:
http://raypeat.com/articles/articles/coconut-oil.shtml
"...While components of coconut oil have been found to have remarkable physiological effects (as antihistamines, antiinfectives/antiseptics, promoters of immunity, glucocorticoid antagonist, nontoxic anticancer agents, for example), I think it is important to avoid making any such claims for the natural coconut oil, because it very easily could be banned from the import market as a "new drug" which isn't "approved by the FDA." We have already seen how money and propaganda from the soy oil industry eliminated long-established products from the U.S. market. I saw people lose weight stably when they had the habit of eating large amounts of tortilla chips fried in coconut oil, but those chips disappeared when their producers were pressured into switching to other oils, in spite of the short shelf life that resulted in the need to add large amounts of preservatives. Oreo cookies, Ritz crackers, potato chip producers, and movie theater popcorn makers have experienced similar pressures."

So to apply this just eat some coconut oil and apply to skin?

Well, to get to 5g-10g of caprylic acid you may need 50g - 100g coconut oil. These amounts are probably not needed by most people but for somebody with a serious issue I think it would be doable as it means just eating 30g coconut oil with every meal. For tumors close to the surface they just rubbed the equivalent of a few grams of caprylic acid on the skin, so it could be doable with topical coconut oil. Other than that, Peat said that as little as 1tsp. coconut oil may be enough for prevention of cancer and CVD.

I think probably Defibron would work as well.

That’s a lot of coconut oil. It’s more expensive than coconut oil, but why not use just pure C8? Brain Octane Oil - 16 oz.

You can. After posting the study I saw a few sources online say that most MCT products sold in stores are predominantly C8. Not sure why, maybe (ironically) it is the cheapest to extract from the oil. Either way, it is a win-win for all of us (if true).

Caprylic acid - Wikipedia

also available on Amazon as capsules or liquids for coffee or direct ingestion. not expensive.

As Mito suggested and I followed up on this, most MCT products in stores seem to be predominantly caprylic acid. So, no need to buy isolated and expensive caprylic acid products.

Interestingly also a very antifungal substance. Some people believe fungus is a cause of cancer

Yep, and antiviral, antibacterial, and antiparasitic (worm). Pretty good substance all-around.

I get the runs from consuming even a teaspoon of MCT oil but do fine with coconut oil. Does anyone else have this problem with MCT oil? Is it just a matter of starting with a teeny amount and then very slowly increasing daily consumption?

My gut may be more messed up than I think because it's not just MCT oil that disturbs it. I cannot drink any raw milk without getting the farts. I drink a cup daily anyway and am waiting to overcome this. Long time and still waiting. However, years ago I drank raw milk in large quantity with no problem. Then went low carb high protein and fat, screwed everything up. Found Ray Peat's work and have been trying to get back to Milk Heaven ever since.

Whenever I take Caprylic acid internally, it irritates my digestive tract and gives me horrible headaches. But I use it topically for lots of things.

I tried out Asprey's Brain Octane. I will say that there is a marked difference in how it feels verse plain coconut oil. It seems to offer some anti-anxiety effects in me. Chills me out, makes thinking easier too.

how did you use it - topical or oral, and how much?

I just got another brand that is supposed to be 100% caprylic acid

I used about a capful...hmm not helpful, maybe like a bit more then a teaspoon. I used that three times a day. I took it orally, so drinking it.
