Cancer death rates have been falling over the last few decades.

And, according to a new report from the National Centre for Health Statistics (NCHS), the same holds true for children and teenagers. From 1999 to 2014, the cancer death rate among kids and teens aged 1 to 19 declined 20 percent.

And along with that, brain cancer is now the most common cause of cancer-related deaths, taking over from leukaemia. These two types of cancer still account for about of all cancer deaths.

The report noted major advancements in cancer treatments, in particular, leukaemia, may have a hand in the overall decreasing cancer death rate.

Here's what the decline in cancer deaths looks like, over the 15-year period, per 100,000 people.
