A medical center grant will match Foster's gift, for a total of $15 million.
Foster lost her husband Stanley and a brother to cancer, remarking that her brother's death was marked by a lack of beds.
The 108-bed Jacobs Medical Center is under construction and scheduled to open in 2016. The Pauline and Stanley Foster Hospital for Cancer Care is said to be the only in-patient facility of its kind in San Diego County. The venue will work closely with UCSD's Moores Cancer Center to align patient care. Moores provides clinical trials, nutrition support and family counseling.
San Diego County is the fifth largest in the country, and cancer is its No. 1 cause of death.
