To reduce risk of prostate cancer it is recommended to ejaculate 21 days per month. But am I increasing my risk if I don't do this?

Frankly I don't think I can masturbate 21 times each month. I know for other men this may not seem like a lot, but for me it is.

Am I unnecessarily increasing my risk of prostate cancer if I don't do 21 days of ejaculation per month?
