There's not a really a need to have them removed. It wasn't an illicit act and I don't know why she had them done.
For instance, I know someone who had a double mastectomy. She had them reconstructed with implants because she was very uncomfortable with the scars, etc.
Yes, it's good to offer suffering up, but it might not really be a sin.
She should remove the fake breasts as soon as possible.
Her body is a temple of the Holy Ghost and breast implants just seem incompatible with the idea of honoring her body with modesty and decorum.
Inciting lust is often the reason why a woman would do such a thing to her body.
I want to retract this comment, as when I wrote it, I only had in my mind women that do this out of vanity and sinful sensuality.
I understand that there may be other clinical reasons for breast implants.
To both of you: her reasons were 100% VAIN as she didn't have any medical condition whatsoever.
She had small breasts before and she used to wear more modest shirts/blouses, but she got implants at least double or triple her natural size, they're not huge, but they're considerable, and NOW she wears tight shirts, very low cut, and she is parading and exposing them around.
If that's not vanity and pure lust, I don't know what is.
And further, i myself told her that it was a mortal sin what she did, because now she is showing them around and before she wouldn't dress like that, and what did she tell me? That the reason she got implants was "between me and my husband".
PURE LUST.
