Answer 1

You only hear about cancer that makes people unwell. Cancer in the brain, blood, chest or abdomen is hidden away and can progress undetected for a long time to the point where it is hard to fix and makes you really sick. You would notice pretty quickly if you developed a tumour in other places like the bicep or calf and in the developed world, get it fixed at a very early stage
