Happy news for me, the type in flaxseed was not found to have this correlation. I use flaxseed since I'm a vegetarian. Although it is not really relevant to me anyway, since I am a female, but if something causes an increase in one kind of cancer, it might do so for other cancers.

Omega-3 fatty acids have been shown to have many health benefits. But they may have risks as well, including an increased risk for prostate cancer.
-----
Compared with men in the lowest one-quarter for omega-3 levels, those in the highest one-quarter had a 44 percent increased risk for low-grade prostate cancer and a 71 percent increased risk for high-grade cancer. They found the association with three different omega-3’s — eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and docosapentaenoic acid (DPA), which are all found in fish and fish oil supplements — but not with alpha-linolenic acid, which comes from flax seed.
The findings are an association and do not imply causation. But according to the lead author, Theodore M. Brasky, now at The Ohio State University, omega-3’s can affect gene expression and, in high doses, be pro-oxidative or suppress immunity, all of which could promote cancer.
Still, he added, the possible “increase in prostate cancer risk doesn’t preclude a beneficial effect for other diseases.”
