I don't think it 'means' anything as such. It is actually rare for women with small breasts to be estrogen-deficient or anything like that. Some women just have naturally smaller breasts, it tends to be genetic.
You could try something like suction to see if it makes a difference. Or maybe massage. Some people on here take herbs but I would be wary as you are not sure what exactly you are doing to your body and what problems you could be causing for yourself.
