I'm sorry you're going through this.
I've read somewhere that most (not all, but most) women have unequal sized breasts. I certainly have unequal sized breasts, but this trend started in my early teenage years.
I know there are women who do end up having breast cancer and their symptom was unequal sized breasts. So its good you are getting this checked out.
However, there are OTHER causes of relatively rapid unequal sized breasts - such as giant fibroadenomas. (Fibroadenomas are almost always benign.)
This case report cites a quickly expanding breast mass that was 23x28 cm. (That's roughly 10inches x 10 inches.) www.ncbi.nlm.nih.gov/pubmed/20... Of course,fibroadenomas can be much smaller than this.
This 43 year old had a fibroadenoma that was roughly 5 pounds. (size 23x20x13 cm and weight 2680 grams) www.ncbi.nlm.nih.gov/pubmed/16...
I think many women have increased breast sizes when their breasts are exposed to estrogen, such as when they take birth control pills or become pregnant.
Good for you for getting this checked out! I know this process can be full of anxiety, and I'm not trying to diminish what you are feeling. Holding my hand out to you.
