Puerto Rican singer-songwriter Draco Rosa will undergo Monday a second test to enable a group of doctors to certify for the second time that he is free of cancer after being treated for the disease.

"Draco is free of cancer, but on Monday they'll give him a second test to certify it," Rosa's representative Angelo Medina told Efe, adding that if the whole recuperation process has gone well, the artist will have a bone-marrow transplant in the next two weeks.

Medina said he had not talked to the former Menudo artist over the past two weeks while he was being treated in California, but after talking to him on Friday, his rep found him "a little disheartened, but with all the will in the world to conquer" the disease.

Draco Rosa had a recurrence of cancer last December, when it was confirmed that he was suffering from non-Hodgkins diffuse large B-cell lymphoma.

Rosa's health was having a relapse for the first time since it was announced in December 2012 that the artist had overcome the cancer he was suffering, after being treated for a lymphoma near the liver for more than a year and a half at a specialized medical center in California.

News of the relapse came after he took the stage last December with compatriots Ricky Martin, Juan Luis Guerra, Juanes, Enrique Bunbury and Residente of the group Calle 13 for two concerts that packed the Jose Miguel Agrelot Coliseum in Puerto Rico.

In February 2013 Draco Rosa launched his disc "Vida," with which he kicked off a tour to Argentina, the United States, Mexico, Colombia and other countries. But in the midst of that tour he had a routine test - and was diagnosed with cancer, Medina said Saturday.

The artist appeared for the last time in Puerto Rico last March together with Panama's Ruben Blades and the Dominican Juan Luis Guerra.

Draco Rosa, 44, has been getting ready for the "Corre por Otro" event, which will be held this coming February to raise funds for kids with cancer in Puerto Rico.

A one-time member of the teen musical group Menudo, he has been a composer and producer for Ricky Martin and other international music stars. EFE
