The capital city of Oman will welcome around 4,000 cancer control experts from more than 140 countries to the event.
The bid was put forward by the National Oncology Centre Royal Hospital Muscat, the Oman Cancer Association, the Oman Convention Bureau and the Oman Convention & Exhibition Centre.
The first International Cancer Congress was held in Madrid in 1933 and has since taken place in destinations including Moscow, Tokyo, New Delhi and most recently Paris, France in 2016.
A member of the bid team, Dr. Zahid Al Mandhari, said: "The World Health Organization predicts that incidences of cancer in the Middle East will double by 2030, so felt it was crucial to keep raising awareness of the disease, especially across the Gulf Cooperation Council countries (GCC) and Africa.
"Welcoming the WCC in Oman will certainly foster our work to educate the local population, and help the global cancer community to further make a difference."
