Can getting hit in the balls cause testicular cancer?

over the past weeks for some reason ive been hit in the balls alot and every time getting more and more worried that its really damaging them. i think overall its about 6 times now! the first was really hard the second was hard the third was hard i cant remember the fourth the fifth one sorta hit my groin and the sixth one was quite hard. im getting really worried and have been searching around the internet and it says its unlikely to get testicular cancer especially when your 12 and you would have to get hit extremely hard to get cancer but im worried that the constant hits maybe causing damage. does anyone think i will actually have cancer? :(
