It depends upon the person. Some girl's breasts grow until they're 18, some until they're 13. It just depends on your genes.
Around 10.5 years old.
Yes they can. Some even before that age.
No--she is going through puberty.
it probably means you are growing.
Many girls get this burning sensation as their breasts are growing or right before their period
yes it is normal to have stretch marks on your breast that just means you are growing.
Normally before 18 years old. But it really depends. Your ears and noses never stop growing.
Around 14-17 to start growing. At the age 16-17 it will start growing faster and longer.
Breast size is inherited from a person's mom and dad. Being plump can make breast somewhat larger because they are largely composed of fat and other tissues, of course. You might find it interesting that breast size has little to do with the girl's age . . . well, outside of puberty when breasts first start appearing and growing . . .
16 years old
Yes, although somewhat rare, it can happen, some children have been recorded as having their period (astonishingly) at two years old.
they typically start growing sometime between the ages of 8 and 13.
Extremely unlikely. 1/20,000 women will get breast cancer before 25.
