cancer estradiol

Hey guys! Since two years i have a slightly lump behind the nipple that seems gyno, and it appears and disappears. Now im experienced armpit sore ( started 1 week ago ). I was doing some research and it seems that there is some relation elevated estrógen levels and cáncer. What do you know...

My nurse told me she gets concerned if a man's E2 hits 70 due to increased risk of cancer. I did some Googling and came up empty except for a possible increase in breast cancer risk(for men). Is there any strong correlation between elevated E2 and cancer in men...
