What does it mean if you have a inlarged testical? - testical canser

For a long time (several years) my left testicle was twice as big or bigger than my right, and sometimes a dull all in one boat. I did some research and to see who could possibally canse and a friend of mine through something, but I had an envelope around it or something for nothing inlarged own. Could it be otherwise? How serious? What should I do?
