Wifes nipples are bleeding, both of them from time to time. Whats the likelihood of the "big C"?

As said in question there has been some bleeding on and off for about a month in both of them. She now has an appointment for a scan and possible biopsy next week. I read in one Googled article that if both have bled then cancer is unlikely – is this giving false hope that its not serious? Dont know what to think now?
