Serena Williams said she left her comfort zone to sing I Touch Myself to urge women to perform self-examinations for breast cancer. But the message was worth it.

The tennis star sang a rendition of the 1990 Divinyls song in a clip posted Saturday ahead of Octobers Breast Cancer Awareness Month .

Chrissy Amphlett, lead singer of the Divinyls, died after battling the disease in 2013. The song, which originally had a sexual connotation, has been repurposed for the I Touch Myself Project to promote early breast cancer detection.

Yes, this put me out of my comfort zone, but I wanted to do it because its an issue that affects all women of all colors, all around the world, Williams wrote on Instagram Saturday. Early detection is key it saves so many lives. I just hope this helps to remind women of that.

Watch Williams sing above.
