Omega 3 DHA and EPA study showing reduction in tumor size

I am newly diagnosed with ER+++/HER2+++ and in doing research I found several studies that cite Omega 3 supplements -- specifically EPA and DHA -- that are being shown to reduce the risk of breast cancer and reduce the size of tumors. I am wondering if anyone else has read about this or taking these supplements.

"The team found that mice exposed to the fish oil-derived omega-3s EPA and DHA experienced a 60–70 percent reduction in tumor size, as well as a 30 percent decrease in the number of breast tumors."
