Axillary tail of breast -
Detailed Answer:
Hi.
Thanks for your query, albeit short and specific.
Noted the history and understood your concerns.
The area in right armpit that you feel thicker and pain mimics like that of breast is basically the breast tissue and called as axillary tail hence will behave the same as rest of the breast/s.
So no worry.
This can be confirmed by Ultrasonography.
Since the breast pain and tenderness started with the starting of birth control pills, it is certainly due to the hormonal changes that the pills cause and if you have option for another type of birth control, it will be better to change over.
I hope this answers your query.
Please feel free to ask for further relevant queries if you feel that there is a gap of communication.
Thanks for your appreciation.
