Can someone give me input?

my wife took a mamography test 6 months ago. it all came back clear. about 3 weeks ago she noticed a lump on her . then 5 days later she noticed a on her underpit. we went to the doctor took a mamography, biopsy,and a sonar gram. the test came back positive. its in her lymph nodes. they dont know the extent of it yet whether it spread. we have an appointment with a doctor in sloan kettering on dec 29th. she will be going for further testing and speak to the surgeon. the tumor is an inch in her . by the way it hurt and the bump under her armpit hurt. waiting a week for these tests isnt that to long? what are the chances that the cancer has spread to other parts of her body? my heart is bleeding for her i cry at night by myself. im positive when i am with her. i have 3 little children and im flipping out inside. do you think we will get through this with a positive outcome? the term metastatic was used. however is it true metastatic in such a short time frame?
