You did not read the linked Blog:
Some data also suggests that fish oils may promote cancer metastases
more potently than safflower oil:
"Rats were kept on either a low-fat diet or on a fish oil (omega-3
PUFAs) or safflower oil (omega-6 PUFAs) diet for 3 weeks before the
administration of colon cancer cells to the portal vein, until they
were sacrificed at 1 or 3 weeks after tumor transplantation. At 1 week
after transplantation, the fish oil diet had induced 7-fold more
metastases (in terms of number and size) than had the low-fat diet,
whereas the safflower oil diet had not affected the number and total
volume of metastases. At 3 weeks after tumor transplantation, the fish
oil diet and the safflower oil diet had induced, respectively, 10- and
4-fold more metastases (number) and over 1000- and 500-fold more
metastases (size) than were found in the livers of rats on the low-fat
diet."
"PUFAs are incorporated into the membranes of both cancer cells and
normal cells, altering their physical and functional properties (30,
39), which may interfere seriously with immunological surveillance
against cancer cells. Furthermore, n-3 PUFA supplementation decreases
cytokine production (40) and MHC class II expression on the cell
surface of antigen-presenting macrophages (41, 42), thus interfering
with the immune response (43, 44)."
Eating food rich in n-3 fats (fish oils) would also depress cytokine
production and MHC class II expression on the cell surface of antigen-
presenting macrophages, also reducing the effectiveness of immune-
system control of malignant cells.
