It's Cinco de Mammo week! During the week of April 30 through May 4, South Texas Health System celebrates a special week dedicated to the early detection of breast cancer. South Texas Health System facilities, including STHS ER Weslaco, will offer reduced price mammograms, extended hours and a fiesta atmosphere- aguas frescas, fiesta-themed food and Mexican decor. We are encouraging women to bring a muchacha - your mom, sister, or amiga - to get a mammogram during Cinco de Mammo week.
