It is good if your doctor is trying to preserve your anatomy "down there", but is she just saying that or is she really and does she even know how to accomplish that?
It does seem strange that she did a laser first. Going from a laser to a resection on both sides seems like an extreme leap. On the other hand, if my friend's doctor had done that, perhaps she wouldn't have had to have a vulvectomy.
My friend who had vulvar cancer had the kind that starts with the white skin. Her doctor always did skinning and creams. She went on this way for about 30 years before it turned into invasive cancer and she had to have a vulvectomy (in her mid sixties). After the vulvectomy and then radiation, the cancer never returned. She lived about 11 more years and died recently from an unrelated cause.
Please seek a second opinion before you let your surgeon cut on you. The resection your doctor suggests sounds too extreme, especially for someone your age, and once it is done, there is no going back.
By the way, a common mistake for this kind of cancer is receiving radiation BEFORE the vulvectomy. After radiation, the wound is difficult to heal and in some women, never heals. Make sure that doesn't happen to you.
Blessings to you.
