Answer:
Cancer is everywhere and in profoundly big numbers. The lifetime risk of developing cancer is 1:2 for a man and 1:3 for a woman. Most of those cases occur in the elderly, but an awful lot of young and middle-aged people are stricken too. Along with heart disease, cancer is the top killer worldwide.

Answer:
No, it isn't. In countries like yours and mine (I live in the UK) cancer may seem more common than in some less developed countries. There are a couple of reasons for this:

Superior health care; people are living longer than ever before. Cancer is mainly a disease of ageing - the majority of cases occur in people over 60. More older and elderly people = more cases of cancer.

Better screening and detection, so cancers are detected which might be missed in countries where screening is less widespread and less sophisticated.

2. It's in the media all the time.
