Help Canada's brightest researchers unlock life-saving discoveries 

Using technology so cutting-edge it didn’t exist a few years ago, CSS-funded researcher Dr Francis Rodier and his team are targeting cancer cells that go into hiding – to find ways to prevent it from coming back.  

Stopping cancer cells from coming back 

[Dr Francis Rodier, a cancer researcher, appears on screen. He is putting on a white lab coat before sitting in his lab.] 

Words on screen: Dr Francis Rodier. Canadian Cancer Society-funded researcher.  

Dr Rodier: My name is Francis Rodier. I'm a researcher funded by the Canadian Cancer Society. 

[Dr Rodier walks through his lab. Another researcher works at a lab bench. Dr Rodier sits on the lab bench and talks to the camera throughout the video.] 

Dr Rodier: The project funded by the Canadian Cancer Society concerns tumour dormancy, which is a concept where we think that the cancer is cured, but eventually the disease will come back. 

[The working researcher injects a liquid into small containers.] 

Dr Rodier: We don't really understand why this disease is coming back and why it takes a different time from person to person. 

[The researcher continues to work in the lab.] 

Dr Rodier: This project on cancer dormancy is made possible by technologies that did not even exist a few years ago. We are talking about technologies that now allow us to identify every single cell in a tumor. 

[Dr Rodier stands with his arms crossed.] 

Dr Rodier: Every moment is a gift means the best moments you spend with your loved ones, your friends, your family. 

[The researcher continues working in the lab.] 

Dr Rodier: And we can also think about that in research where you have great moments of discovery and suddenly everything gets clear in your mind. 

[Dr Rodier puts on his white lab coat and walks in the lab.] 

Dr Rodier: These beautiful moments actually happen quite often. 

[The researcher continues working in the lab.] 

Dr Rodier: So that's a nice story in science, it's very important to get continuous funding to keep pushing forward the research breakthroughs. 

[Dr Rodier stands in the centre of the lab.] 

[Words on screen: World-leading cancer innovations start in Canada. Help move research forward.] 

[Words on screen: Every moment is a gift. Help give more of them. Donate monthly.] 

[The Canadian Cancer Society logo and the words IT TAKES A SOCIETY appear below the words on screen.] 

*One-time donations and the first payment of new recurring donations made in support of cancer research by midnight on December 2, 2025 will be matched, up to a total of $55,000, thanks to the Estate of Glenna Mandle and an anonymous donor.

Matching donations come from corporate, institutional and individual donors who agree to match donations to specific programs, in order to inspire others to give. Donors may also require CCS to raise matching funds as a condition of their support. In both cases, these matches allow for even greater impact. For more information about matching, and our partners, please visit cancer.ca/matching. In the unlikely event that donations raised exceed the specific funding requirement, CCS will redirect funds to similar programs or where needed the most.
