Hi there,
I think it's important to clarify what tuberous breasts mean before addressing your particular concerns. 
Tuberous breast deformity generally refers to a developmental form of constricted breast base anomaly characterised by a "tubular" shaped breasts associated with different degree of breast deficiency, high riding infra-mammary folds and enlarged or even "herniated" nipple areolar complex. It has varying degree of severity and could sometimes contribute to certain degree of breast asymmetry when it affects the two breasts in a different way.
Based on the above descriptions, I would be hesitant to "label" you with such condition. However you do have moderate degree of breast ptosis and asymmetry and without knowing your clinical background (?age, ?previous pregnancies, ?weight loss etc), it's difficult to judge whether this is an acquired consequence due to a variety of environmental factors and social circumstances. 
I think a breast implant lift procedure will help improve the shape, size and symmetry in your particular situation. Details regarding logistics and recovery can only be guided by an informed consultation with a plastic surgeon of your choice. As there are multiple factors involved depending on numerous possible settings, it's important to find a plastic surgeon who understands your concerns & appreciates your desires before formulating plans for the actual surgical procedure. 
Hope that helps.
Best wishes
