There is a lot of contradicting data on breast cancer statistics worldwide. The top 3 countries with the highest rates of breast cancer in 2018 are said to be Belgium, which had the highest rate of breast cancer in women, followed by Luxembourg and Netherlands. However, in 2019, an estimated 268,600 new cases of invasive breast cancer were diagnosed among women and approximately 2,670 cases in men.
According to research from Globocan in 2018, Syria made the number one spot for the country with the lowest breast cancer rates with the lowest mortality rates at 85.0 per 100,000 cases. As of 2020, breast cancer is the most commonly occurring cancer in women and the second most common cancer overall after lung cancer, with over 2 million new cases in 2018.
Breast cancer is the most common cancer in women both in the developed and less developed world. Which brings in the controversy: the data collection methods used in developing countries are not the same as those used in developed countries. For example, incidence rates vary greatly worldwide from 19.3 per 100,000 women in Eastern Africa to 89.7 per 100,000 women in Western Europe.
In addition to that, numerous cases are not reported in developing countries which adds more discrepancies in the final data presented by Globocan or any other institution reporting on cancer. There is already a huge controversy behind the story of cancer and this data can help us debunk the myths if done well.
