Worldwide cases of cancer are likely to rise by nearly 75 percent by 2030, driven by demographic and lifestyle factors, according to a study published on Friday in the journal The Lancet Oncology.
A team led by Freddie Bray of the International Agency for Research on Cancer (IARC) in Lyon, France, said that in 2008 there were 12.7 million new cases of cancer, which would rise to 22.2 million by 2030, with 90 percent of the rise occurring in the poorest countries.
In many countries, falls in cancers linked to infection have been offset by cancers of the colon, rectum, breast and prostate which are associated with a "westernised" diet, they said.
The study used data from GLOBOCAN, an IARC database of cancer cases in 184 countries.
According to Martin Seligman, an expert in the field of positive psychology, there are four things that affect our health that we have control over: smoking, exercise, diet, and optimism. O
ptimism is at least as important as the others. Though scientists don't fully understand the biological mechanisms at work, they know that negative emotions can cause a spike in the hormone known as cortisol, which suppresses the immune system, making it harder to get better.
