RELENTLESS Against Cancer is a non-profit organization committed to raising funds that support research for the development of treatments that ultimately will eradicate all cancers.


“We must be RELENTLESS in our will to live, our faith that we will overcome, and our hope that no one will ever have to endure cancer treatment again.”  Nathan Shatsoff, Founder

RELENTLESS Against Cancer Says Goodbye and Thank You!

After much thought and soul searching, we have decided to end RELENTLESS by December 31, 2018. With the incredible support and assistance from family, friends, businesses, doctors, nurses, and researchers, we have been able to donate $115,000 to various health facilities for cancer research (see bottom of this page). We truly appreciate all the support we have received over the past eight years! It would have been impossible without your help.

We will never forget the many special people we have met during our journey; some who have beaten cancer, some who are still fighting, some who have lost a loved one, and some who just wanted to share their story about the impact this awful disease had on their life. We shared hugs, tears, and our own stories with many of our supporters.

RELENTLESS was started by Nate (our son, brother, nephew and friend) as a way of giving back and not standing on the sidelines while he fought his battle. He chose the name RELENTLESS not only because of the nature of the disease, but also the need to be relentless in the battle that he and so many others have fought. Nate would be proud of all that we have accomplished, and we are sure he would say to everyone that no matter what STAY RELENTLESS!

We plan to make one final research donation from RELENTLESS by the end of this year.  There are so many worthwhile organizations that are fighting to eradicate all cancers.  We at RELENTLESS are so glad we could be a part of it of the fight.  We hope you’ll continue to be RELENTLESS through donations to other organizations or your local hospital or research center. 

On a personal note, the Shatsoff family will continue our efforts in a private manner. We will never stop with our own donations in the hope that we can see more therapies developed and hear about many more survivors. Thank you so much for your support over the years!
