Can tuberous breasts grow?

Tuberous breasts can enlarge with weight gain.  But the shape of the breasts will essentially remain the same. 

Gaining weight is probably not the best way to increase your breast size. The best way to increase your breast size is with implants or fat grafting. Any women desiring breast augmentation surgery is a candidate as long as there are no health problems present which would preclude her from having surgery. If the desired goal is to enhance or restore size and shape or to improve asymmetry, breast augmentation is a viable option. Breast augmentation can improve a body image, self-esteem, self-concept, and quality of life.Ideal Candidates for Breast AugmentationDesire larger, shapelier breasts.Moderate degree of breast sag and smaller breasts, whose problem can be solved by enlargement.One breast that is noticeably smaller or is positioned differently than the other (asymmetry).Uneven chest wall or rib cage.Women requiring breast reconstruction following a mastectomy.Restore breast volume or shape following pregnancy, breast feeding and/or weight loss.

There
is not much to be gained by labeling someone with tuberous breasts. An
operative plan should be developed based on your anatomy. Whether that is
breast implantation, lift or reduction, symmetrization or some combination of
procedures, there is no particular point in stigmatizing your breast shape.
A properly trained, skilled and ethical plastic surgeon can develop a
plan based on your anatomy and give you the outcome that you desire. I
see absolutely no point in diagnosing someone with tuberous breasts or
restricted base deformity. Stigmatizing a young person can have an effect
on the way they perceive the outcome, even if it is outstanding.
