orchitis would be higher on the list than a testicular cancer but both need to be considered. you need a testicular ultrasound (doppler) as soon as you can get it and of course a visit to a urologist. testicular cancer does not really act like this. it is not very helpful to worry unnecessarily about these things until you get a diagnosis. i am sorry that i cannot be more specific but making these "blind" guesses is not something that medical professionals are fond of doing. we like to see these problems first-hand look at the imaging studies and then and only then make a presumptive diagnosis. hang in there my friend (no pun intended).
one of my testices has always been larger. but recently it has grown much larger and hurts (dull pain). so i have always had a larger testicle (the right one) and that has never been an issue. but over the past 2 months it has grown far larger. roughly double the original size. i am going in for tests in about a week. so my real question is that what else besides testiclar cancer coud be causeing this. trying to stay possitive and hoping its nothing that serious. also the pain has come and gone in the past but for no more than a day in the past. but the last two weeks it has hurt fairly constantly
