First of all correct diagnosis is a must, when someone observe unequal size, we have to find out the actual abnormality in larger or smaller breast, either one may be abnormal, there may be poor development in smaller one or maybe hypertrophy in the larger one.
If larger one is really a problem then you can take deep acting safer curative Homeopathic Medicine for prompt response.
Take Phytolacca D Q - One drop Thrice Daily in 15 ml water for 15 days
Silicia 3X Tablets - 5 tablets Thrice Daily for 15 days
Don't massage or apply hard pressure to the larger one.
Wear good quality properly fitted lingeries in daytime on loose fitted garments at night.
Next Steps
