Why Are More People Being Diagnosed with Cancer?

Globally, cancer diagnoses increased by a startling 28 percent between 2006 and 2016, but at least part of the reason is simply that people are living longer. Therefore, they are more likely to be diagnosed with the disease at some point. Screening for various forms of cancer has also improved, meaning that although diagnoses have increased, early treatment is likely to be more successful in prolonging lives. According to research published in the journal JAMA Oncology by the Global Burden of Disease Cancer Collaboration, which reviewed the prevalence of 29 types of cancer, 17.2 million people were diagnosed with some form of cancer in 2016, and 8.9 million people died from cancer. Lifestyle factors such as smoking, drinking alcohol, eating processed foods, sun exposure, and being sedentary were also blamed for an increase in certain cancers, above the expected rise due to longer life expectancy alone.

Looking at cancer around the world:

  • The biggest increase in cancer diagnoses occurred in low and middle-income nations, where tobacco products are heavily promoted and fast food options have become more readily available.

  • Tobacco use is reflected in the continuing domination of lung cancer as the world's most-deadly cancer, causing approximately 20 percent of global cancer deaths in 2016.

  • For women, breast cancer is the most deadly form of the disease. Cervical cancer rates have dropped thanks to the prevalence of the HPV vaccine, although they remain high for women in the developing world.

Quote from Dr.Livia S. Eberlin:

We’re getting so much better at detecting [cancer]. I don’t know if you heard about this, but a lot of people will argue that there’s an overdiagnosis right now, that if we didn’t have these amazing technologies, we may not even ever know that we had a cancer that might have ended up not really developing. So yeah, the data is showing that the cases of cancer are just increasing. I’m really for early detection and being proactive about knowing as early as possible. But I think for a really good part of the future, we’re still going to be using technologies like this to improve treatment.
