Should I do the MTHFR gene test before getting breast implants?

There is no evidence in the massive body of scientific evidence that Breast Implant Illness exists, or any other systemic illness. This includes the rare folate enzyme mutation MTHFR. Despite the large Facebook BII group numbering over 120000, there are less than 2000 patients who've reported to their surgeon any of these common symptoms that are included (by BII advocates) as caused by their breast implants. There are somewhere between 50 to 80 millions women in the world currently with breast implants. You'll be fine.

I do not recommended that you rely on lab work for “proof" that you will or will not develop BII. This will be a waste of time and an unreliable approach as no definitive test(s) are available to determine if your implants are the cause of your illnesses. Many women who are very ill are disappointed that their lab results do not reflect their sickness. Once you realize breast implants are contributing to your symptoms, it is best to explant in a timely manner to prevent further progression of illness.
