Since kindergarten, or even more, since birth, we differ between each other very much. The hair and skin color, but also, the weight and size, though we are all at the same age. Even more, some twins are different in weight and size when they’re still children!
HERE ARE SOME FACTORS THAT MOSTLY AFFECT THE CHANGES IN THE BODY DIFFERENTLY, IN THE SAME AGE:
THE FAMILY HISTORY
Your genes are more likely to predict your breast baseline, but not your size as well. “Women often are born with their breast size, but it can change in their lifetime,” states Nazanin Khakpour, M.D.,a surgical oncologist specializing in breast cancer at Moffitt Cancer Center.
If your mother and sister have big breasts, it’s not a guarantee that you will also, but you’re more likely compared to some girl who comes from a family of women with smaller breasts.
YOUR WEIGHT
Depending on your weight, you notice changes in the size of your breasts. Probably, you notice the changes on your breasts at the first place.
Because breasts are made up of supportive tissue, milk glands and pretty much, a bunch of fat, it’s hard to tell the actual size of breasts at girls who are overweight. Also, the amount of different tissue differs from person to person – some have more fat tissue than others, who have more supportive tissue.
THE TYPE OF EXERCISE
Have you ever seen a swimmer or ballet dancer with big breasts? Also, lifting wright, doing push-ups and other pectoral exercises will make your breasts look flatter, because you turn tissue into muscle.
Doing too much exercise can flatten the supportive and fatty tissue of the breasts, but regular and “normal” exercising can actually make your breasts to look fuller, lifting a certain part of the fatty tissue who turns into muscle.
BIRTH CONTROL
“The Pill” can actually make your breasts look bigger, because of the water retention in your body. Also, the pill can make some disbalances in the hormones and glands, so this impact of bigger breasts will not be permanent, for sure.
At the end, just to say that most of the variation in breast size is due to a woman’s amount of mammary and adipose tissue. Physically speaking, the best prediction factor of your breast size would be your weight and body type.
Thinner women usually have smaller breasts, and vice-versa. The stage of development in puberty can also play a role, but that factor is also connected to body shape and size: again, thinner girls tend to start growing breasts slower or maybe even later.
