The annual ‘CADENA 100 Por Ellas’ charity event, which originated in 2013 following a listener’s personal account of breast cancer, was held on October 24, 2026, at the Movistar Arena in Madrid to benefit the Spanish Association Against Cancer (AECC).

Singer Leire Martínez released the official anthem, ‘Quédate en su voz’, ahead of the event. The song incorporates backing vocals from breast cancer patients to reflect their lived experiences, with all net proceeds from its digital exploitation donated to the AECC to support research and patient families. 

The sold-out concert featured a diverse lineup of musical artists, including Fangoria, Pablo López, Rosana, Funambulista, Marlon, Conchita, Huecco, Marlena, Vicco, and Edurne. During the event, presenters Javi Nieves and Mar Amate emphasized themes of unity and support, highlighting that patients are not alone in their struggle.
