History of Mammothon

Mammothon 2018 was hosted by the Central Regional Cancer Program in partnership with 23 Ontario Breast Screening Program locations and was successful at screening 532 women.

Where It All Began

Created at the OBSP London site, the original concept of Mammothon was called, “Fifty/50.” The aim was to screen 50 women over the age of 50 who have never had a mammogram. The event first launched in the North East Region in 2007 and has grown exponentially ever since.

On May 7, 2014, six Ontario Breast Screening Program (OBSP) mammogram imaging sites in the Central Region participated in the first Mammothon. This one-day screening event was organized by the Prevention and Screening Team at the Central Regional Cancer Program to encourage women who were under or never screened for breast cancer to get a mammogram. This fun, community-driven, one-day screening event resulted in a total of 235 women being screened for breast cancer. Now in it’s sixth year, thousands of women have been screened across the province during Mammothon.

Mammothon as we know it today was developed by the Central Regional Cancer Program.
