DALLAS (July 2, 2012)--Former President George W. Bush has been helping to renovate a women's cancer screening center in Zambia during a weeklong trip to Africa.

Bush, clad in a T-shirt and jeans, painted and hauled lumber at the Ngungu Health Center in Kabwe, about 90 miles north of the Zambian capital, Lusaka.

The center will start screening and treating women Tuesday for cervical cancer and pre-cancer.

The former president and his wife, Laura, are in Africa to promote a partnership between the George W. Bush Institute, the U.S. President's Emergency Plan for AIDS Relief, UNAIDS and Susan G. Komen for the Cure, that aims to fight cervical and breast cancer in sub-Saharan Africa.

The former first couple arrived in Africa over the weekend, the Bush Presidential Center said.
