Can I remove the fat from my boobs into my butt?

Thank you for your question.I don't recommend it. Since there is a potential for breast cancer in breast cells, it is not a good idea to transfer fat from the breasts to any part of the body. Please always consult with a board certified plastic surgeon.
Take care,

There is a risk that the transferred tissue from the breast could develop cancer and go undetected. Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA

Breast tissue is not a suitable donor for a brazilian butt list.  Remember that breast cancer affects between 1 and 9 women so it is not advisable to transfer breast tissue to the butt.

Dear idania77,you will most likely not have enough fat in your breasts to consider fat transfer to buttocks. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. You will get the best recommendations after a thorough examination.Daniel Barrett, MD, MHA, MS

Hello idania77 - Thank you for your question.
I do not recommend transferring fat from the breasts to any part f the body. There is the potential for breast cancer to be in breast cells and that is not advisable to transfer. Next step for you is to schedule a consultation with a board certified plastic surgeon to discuss your options and goals. 

Hello
 Thank you for your question.
This procedure will depend o the doctors preferences, most doctors do not like to perform liposuction on the breast area.I would recommend you to contact a board certified plastic surgeon and discuss the best options for you.

You never want to transfer fat from your breasts to the buttocks because of the potential for the breast tissue to become cancerous  and you want to be able to monitor your breasts with periodic mammograms when age appropriate.
