A new report by the Statistical, Economic and Social Research and Training Centre for Islamic Countries (SESRIC), a subsidiary organ of the Organisation of Islamic Cooperation (OIC), indicate that with over one and a half million new cases of Cancer diagnosed in 2012, OIC countries accounted for 11% of the world and 17% of the developing countries total cancer cases.
The report published in July 2016 provides a detailed analysis on incidence, prevalence and death burden of major cancers in OIC member countries.
Unlike the global trends, the report indicate that women are more likely to have cancer in OIC countries than men.
It is reported that age-standardised incidence of cancer in OIC countries was recorded at 127 per 100,000 population for adults and 128 for both men and women in 2012, which is lower than the world average of 182 per 100,000 populations for both sexes and 205 for men and 165 for women.
The findings of the report also indicate that, with 250 thousand new cases, breast cancer is by far the most prevalent cancer in OIC countries.
The second most prevalent is lung cancer, with 105 thousand, and then cervical cancer, with 90 thousand, colorectum cancer with 85 thousand,
and prostate cancer, with 67 thousand cases.
These top-5 cancers accounted for about 40% of all cases diagnosed in OIC countries in 2012.
According to the report, there are widespread gender-based differences in incidence of the most common cancers across the world.
While some of these differences are hormone-related others are largely because of behaviours like smoking and drinking.
Among men in OIC countries, the report finds that five most common sites of cancer diagnosed in 2012 were lung (23.9% of the total), prostate (17.0%), colorectum (12.2%), liver (10.9%), and bladder (7.3%). These five cancers together accounted for about 72% of incidence among men in OIC countries.
Among women, the five most common sites of cancer were breast (49.9% of the total), cervical (18.0%), colorectum (7.3%), ovary (5.0%), and stomach (2.5%). These five cancers together accounted for around 83% of incidence among women in OIC countries.
The reports states that in absolute numbers, cancers in OIC countries caused about 1.02 million deaths in 2012, accounting for 17.4% of the developing countries and 12% of the global cancer deaths.
With 143 thousand deaths of adult people, lung cancer is by far the deadliest cancer in OIC countries.
The second most deadly is stomach cancer, with 85 thousand deaths, and then breast, with 74 thousand, colorectum cancer, with 64 thousand deaths, and cervical cancer, with 47 thousand deaths.
These top-5 deadliest cancers accounted for about 40% of all deaths caused by cancers in OIC countries in 2012.
In 2013, 39 out of 51 OIC countries (76%) have general availability of breast cancer screening at the primary health care level. Such a ratio
is comparable to the developed countries of 97% and the world average of 85%. A similar trend prevail for the screening for cervical and colon cancer. OIC countries as a group recorded less than one radiotherapy unit available for 100,000 populations in 2013 compared to the averages of other developing countries (1.6) and the world (2.0).
In the light of these findings, the Report offers several policy recommendations to address some of the challenges faced by the member countries in the areas of cancer registry, risk factors, and treatment and medication.
