Mayo Clinic Health System Franciscan Healthcare announced a $5 million donation to its La Crosse cancer center Tuesday morning.
The money was given to Mayo by Stephen and Barbara Slaggie who are long-time Mayo Clinic benefactors.
The money will go towards the 3,900 square foot expansion, which is already underway.
Since the cancer center opened in 2004, the number of patients has doubled.
The expansion will allow mayo to meet the demand of patients, it scheduled to be completed this year.
