Popular Nigerian rapper, Olanrewaju Fasasi, popularly known as Sound Sultan has been diagnosed with throat cancer.

SaharaReporters said he has begun chemotherapy in a hospital in the United States.

Chemotherapy is an aggressive form of chemical drug therapy meant to destroy rapidly growing cells in the body. It’s usually used to treat cancer, as cancer cells grow and divide faster than other cells, SaharaReporters said.

Sound Sultan is a household name in Nigeria's entertainment industry having started his career in the 90s. He is regarded as one of the pacesetters of modern-day Nigerian music.

By 1999, he had won numerous local talent-hunt shows. He released his first single "Jagbajantis" in 2000, which was a hit in Nigeria.

After independently releasing other singles and featuring in hit songs of other artists, he was signed by Kennis Music, says SaharaReporters.

Sound Sultan began a working relationship with Wyclef Jean when featured alongside 2face Idibia and Faze on "Proud to be African" from Wyclef's Welcome to Haiti: Creole 101 album.

In 2012, it was announced that Sound Sultan was made a UN Ambassador for Peace for his exemplary lifestyle and career.

In 2015, Sound Sultan released the rap single "Remember" after a long absence from the music scene.

After the fallout of the African Basketball League, he joined forces with the organizers of the Continental Basketball League to become a team owner of Lagos City Stars (the 2017 champions) and a facilitator of the league entertainment.
