Hi Darla,
Sorry to hear about your niece. Cancer is never friendly or fair. I did not have any risk factors but still got cancer in my tongue.
From my diagnosis I had to wait a month before surgery, so the doctors usualy know what they are doing as far as the timing of the treatment. As always, if you have a question about waiting, ask the doctors. I did and got a reassuring answer in my case.
You have found the right website for support and question answering, so ask away.
Take care and fight hard.
Jim
