You have provided very little information here regarding what you mean by "uneven breast," so it will be hard to give a great answer. To me this could mean an uneven contour or shape of an individual breast, or it could mean that there is some difference in size, shape, position, or some other aspect of appearance between the two breasts. Most options for addressing those things and changing those aspects of the breast are surgical. The magnitude of the surgery may not be very great - perhaps something like a bit of liposuction or fat transfer would be appropriate, but it would still be surgical. Two ideas come to mind for non-surgical things that could possibly be used to alter the breasts or the tissues around the breasts, but these are just general ideas and in no way do I know whether they would be appropriate for you. One is the BRAVA device, which is basically an external suction device, much like a "helmet" that you place on one or both breasts and wear for about 10 hours a day for several weeks. There have been reports of modest changes in size and shape of breasts as a result of this device, and we also use it sometimes to expand the breast tissue for fat grafting in certain challenging cases. This is non-surgical. The other idea is CoolSculpting, although, this would likely be more useful in the fatty tissues surrounding the breast, like the armpit, bra line, and chest or upper abdomen areas, and probably not so much on the breast itself. This is non-surgical too, but it would only be useful in very select and specific cases in which reduction of fat volume in those areas accessible by the device would be expected to achieve the goal. Bear in mind that, while avoidance of surgery is a worthwhile goal if there is an appropriate non-surgical remedy to the problem, just avoiding surgery for the sake of avoiding surgery may condemn you to suboptimal results, lots of time, effort, and money spent, and you may have done better to simply go forward with surgery in the first place. My best advice is to schedule consultations with some board certified plastic surgeons who have extensive experience in breast surgery, and maybe even knowledge or experience of those (and maybe others) options for non-surgical treatment I mentioned above. That way you will be sure to get the best advice about how to proceed, and if there is no good non-surgical option available for your specific issue, you will be in good hands to proceed with surgery if you wish. Best of luck.
