Studies like this one are what make it hard to take studies like this one, and reporting on it, seriously.
First of all they were looking at high-risk patients - ie these folk were already on the fast track to CVD, if not already there.
Secondly there was zero controlling for omega-6 intake, which makes omega-3 supplementation all a bit of a waste of time.
It's treating nutrition as pharmaceutical. The reality is that the clinical trial model rarely make sense when talking about nutrition. Nutrition is complicated.
As for the original issue, as noted cancer is complicated too. It's not a single disease. It's virtually the ongoing creation and evolution of new species, within our own body using our own cells. One intervention may help one person with one "type" of cancer, and hinder treatment in another, with ostensibly the same "type" of cancer.
Medicine has come along way in helping both cure and prolong the life of cancer patients, but it's also a long way from any kind of blanket cure.
In the meantime, worry about minimizing risk factors so you minimize your individual risk of getting cancer in the first place. That includes good nutrition and avoidance of carcinogens.
Well, the starting point being "no data contradicts the benefits of omega-3 for curing cancer", this article is one such data and shows how biased the OP is. As the article is a meta-study then there's indeed lots of citations refuting the OP's claim.
Regarding your claim of non-serious work, I find it somewhat funny: you're talking about a meta-study in JAMA. That's your opinion but as I don't know you I prefer to trust professionals. And maybe they didn't searched for omega-6 is because
two studies published in 2005 and 2007 found that while omega−3 polyunsaturated fatty acids are extremely beneficial in preventing heart disease in humans, the levels of omega−6 polyunsaturated fatty acids (and therefore the ratios) were insignificant

That's because such matters are complicated that I trust the way medicine works. If that's your job fine, but your claims lacks evidence.
