Would a breast lift correct my uneven chest and stretch marks? (photos)

Thank you for posting your question here and I am sorry about what you had to go through, I hope you feel better soon.
In your question you mentioned "uneven chest", I am not sure if you mean that you have breast size/shape discrepancy or you are having issues with your actual chest wall. I will assume that you mean breast asymmetry for the sake of answering this question as it appears from the limited photos that you do.
when it comes to breast asymmetry it is very common and can be addressed by performing a lift and in some cases a reduction if the discrepancy is significant. Would it get rid of stretch marks? well if the stretch marks are within the area that will be excised then it will otherwise unfortunately it will not.what it will solve is the discrepancy in size (or at least get them closer to each other, in certain cases complete symmetry is unattainable), and will lift them and provide a more desirable shape and nipple position. That being said each surgery has it's benefits and potential complications and tradeoffs that are better discussed with your surgeon, for example trading a better shape for scars, possibility of not being able to breast feed, possibility of loss of sensation to the nipple etc.
I would also wait till your hormones normalize and your weight is stable before venturing on your surgical transformation journey. I hope this answer helps. Best of luck !

If you are unhappy with the asymmetry of your breast size and shape, a breast lift would be able to help achieve better symmetry. However, the procedure is not designed to address stretch marks.
