Next Saturday, October 24, the Movistar Arena in Madrid will once again become the great stage for solidarity with breast cancer patients in the 14th edition of the Cadena 100 Por Ellas Concert, which is already sold out and whose proceeds will benefit the Spanish Association Against Cancer (AECC). The poster will be made up of Fangoria, Pablo López, Marlon, Marlena, Vicco, Funambulista, Huecco, Conchita and Rosana, who will be joined as special ambassador by Leire Martínez, who this year will be in charge of performing 'Quédate en su voz', this year's official song. Each edition has an unpublished central theme, a responsibility that this time falls on Leire who is enthusiastic about the project as she has the participation of some of the patients, who came to the recording studio to be part of their choirs and give voice to this hymn. As has happened in every Cadena 100 Por Ella Concert since 2011, the song, which premiered this Friday, September 25, seeks to accompany all the women who have gone or are going through this disease and will be heard for the first time live during the concert, which as always will have the hosts of the program 'Good morning, Javi y Mar!', Javi Nieves and Mar Amate, as masters of ceremonies. For those who cannot attend in person, the event can also be followed in streaming through the CADENA100.es website, on the station's official YouTube channel and through the Cadena 100 app. In addition to the tickets, there is the possibility of collaborating with other fundraising actions associated with the concert, such as the sale of AECC merchandising or purchasing a solidarity ticket in line zero. Fifteen years have passed since a listener dared to share her story of surviving cancer on 'Good morning, Javi and Mar!' generating a current of emotion that would be the origin of a social movement. A current of solidarity today turned into a tide driven by Javi Nieves, Mar Amate and the entire Cadena 100 team, which, thanks to the push of all listeners, becomes tangible in the most moving solidarity concert every fall. Since that testimony, more than 200,000 people have joined this tide, sharing each concert, selling out tickets in just hours and singing songs that have become, year after year, anthems against breast cancer.
