For every mammogram appointment scheduled and completed at any Solis Mammography center in the Houston area between Oct. 23 and Dec. 31, $10 will be donated to the Hurricane Harvey Relief Fund by Solis Mammography and its partners in the effort, HCA Healthcare Gulf Coast Division and Hologic. To signal their participation in the campaign, all patients need to do is use the code “Harvey” when they check-in for their appointment.
