Robin,

Do you know what kind of salivary gland cancer it was?
I was also told that chemo wasnt used for salivary gland cancers but there are several clinical trials for recurrant salivary gland cancer.
Call the doctor in the morning and try not to worry. It could just be a swollen lymph node from something else. A couple of months ago, I found a small lump below my ear. It turned out to be nothing and went away about a week later.
