Cancers account for one third of the world's natural deaths, said a member of the board of directors at Iranian Association of Radiotherapy and Oncology.
Hojatollah Shahbazian added aging is one of the leading risk factors for developing cancers whose rate is on the rise globally, as the world's population is getting older.
The specialist said cancer is more prevalent in the European nations than in Iran because of demographic changes that have occurred over the past 20 years in developed nations.
"The population of old people has exceeded that of youth in Europe, leading to an increase in cancer risks," he said, adding air pollution, unhealthy diet, a sedentary lifestyle, as well as a number of unknown factors are among other causes of cancers.
Shahbazian warned against the rising rate of cancer in Iran due to aging.
"The ratio of over-30 population has significantly increased for the first time since the Islamic Revolution was established in 1979," he said, noting between 70,000 to 80,000 people are diagnosed with cancers in the country every year.
The specialist added more Iranians are expected to be diagnosed with cancer in the future in Iran as the life expectancy rises.
"Iran ranks among developed nations in the world in terms of high rate of cancer diagnosis in view of having well-equipped centers and skilled specialists," Shahbazian said.
The specialist noted cancer is curable, if diagnosed promptly.
"Those suffering from cardiovascular diseases, high blood pressure, cholesterol and rheumatoid arthritis are healthy as long as they take their medicines on time. However, once cancer is cured, there is no need to take any medicine," he said.
The specialist said the 10th Annual Congress on Clinical Oncology will be held on Nov. 11-13 in Shiraz, Fars province.
“The congress will focus on cancers and will be attended by foreign and Iranian experts,” he said.
