This is a bit scary. A study that came out this week suggests that if we don't reduce the growth of the worlds population, then the number of cancer cases could rise 75% by 2030.

Just four years ago almost 13 million people were diagnosed with some type of cancer. but a prediction by the International Agency for Research on Cancer predicts that by 2030, that number will jump to 22.2 million.

Research found that any reductions in infection-related cancers, most common in lower-income regions of the world — are being offset by an increasing number of new cases that are more associated with reproductive, dietary and hormonal factors.
