• Can fat injections in the breast increase the risk of developing breast cancer ?
No. There is, to date, no scientific evidence to suggest that the transfer of fat may promote the development of breast cancer.
However, it does not prevent the occurrence, if it should appear. Each patient has their own risk of breast cancer that depends on their age (there is a 1 in 218 chance before the age of 40, and a 1 in 40 chance between the ages of 50 to 59 years old), family medical history, and breast density.
Therefore, every precaution should be taken to limit the risk of coincidence between the occurrence of cancer and lipomodelage (rigorous assessment done before the lipomodelage procedure by a radiologist specialising in breast imaging; rigorous assessment after 1 year performed by the same radiologist). Taking this into account, the patient requesting breast lipomodelage consents to have the preoperative assessment of breast imaging (mammography, ultrasound depending on their age) and agrees to have the required examinations (mammography, ultrasound) after 1 year.
• Can fat injections in the breast reduce the quality of mammograms ?
No, on the contrary. As with any breast surgery, aesthetic or other (excision of benign or malignant tumor, breast reduction surgery, augmentation mammoplasty …) calcification may occur (related to tissue healing). These calcifications (macro and micro calcifications) however, are different from those observed in the breast, and do not pose diagnostic problems for experienced radiologists.
In addition, the modern techniques of fat transfer allow a more harmonious distribution of fat, hence reducing the risk of oily cyst formation or of poor fat graft setting (cytostéatonécrose).
Currently, we can consider that breast lipomodelage, according to the guidelines of an experienced plastic surgeon in this area, does not cause any particular diagnostic challenge for an experienced breast imaging radiologist.
• Can you still breastfeed after fat injections ?
Yes. Pregnancy and breast-feeding are possible but can alter the result of the fat injections.
A period of 6 months is recommended before or after surgery.
• What will happen in the case of extreme weight change?
The fat that was injected in the breast will follow the weight changes. In the case of significant weight gain the breasts get bigger, conversely, in case of weight loss, the breast volume decreases.
• How many cup sizes can we go up using the lipomodeling technique?
A session using the classic technique allows for an increase of about 1 cup size (once the result is stabilised).
For a larger volume increase, it will be necessary to :
- either the number of sessions performed 3 to 6 months apart.
- or use the Brava system.
- or combine lipomodelling and the addition of a breast implant (in this case the injection of fat conceals the breast prostheses well).
In January 2015, the High Authority of Health (HAS) issued recommendations on the practice of lipomodeling breast implants in cosmetic or reconstructive surgery, thus allowing it to be performed regardless of the age of the patients, subject to certain conditions that your plastic surgeon will inform you of.
