Much concern over a small, case-controlled study reported in january 2009 issue of bju international which reported increased rate of prostate cancer for men in 20's and 30's who masturbated 2-7x/week (and a lower rate for men in their 50's who masturbated often).
There are many reasons not to believe the reported conclusions, and it has not been confirmed in other studies.

A much bigger and better controlled study published in JAMA. 2004 Apr 7, showed if anything a reduction in risk of prostate cancer for men of all ages who had frequent ejaculations.

In brief: She's wrong
I'm sorry that she's misinformed.
It has no adverse health consequences so long as it's not part of an obsession with erotica that's robbing you of full participation in life.
