Yes they can. Some even before that age.
Well most girls get a slight discharge (fluid) from their vagina for about a year before there periods start. periods normally start about 2 years after your breast start to develop. You usually get lots of mood swings like Ur mad at everyone then happy all the sudden.
Yes. They'll start hurting before you start.

If you are a girl, you may start to have periods, and notice breast growth. If you are a boy, your voice will start to break, and hair will start to grow around your genitals, on your face, and on your armpits.
Around 10.5 years old.
As soon as you start having periods again, yes. It's a myth that breast-feeding prevents pregnancy - it doesn't
Its means that you are goibg to start your period soon
Usually in the last trimester before giving birth.
The truth is that it could start anywhere on your breast. But most of the times breast cancers start on your left breast and on outer and upper quadrant (if you divide breast in four parts by two perpendicular lines).
If your periods are regular you should start wearing thin pads or panty liners a day or two before your periods start so that incase there is any bleeding or spotting your panties don't get stained.
Before a woman's period, she will retain water. That will cause a temporary slight increase in breast size.
