ANSWER: Hi Sean,

    What type of bedding are you using? Is there any drainage coming from the lump or nipple? Can you tell what color the lump is?
    A female hamster will generally give off an odor and have a white or yellowish discharge coming from her bottom area when she is in season (heat).

QUESTION: there is no drainage, bedding is a typical bedding from the pet store

Answer
Hello again Sean,

    As long as the bedding you are using is not cedar or pine (cedar and pine bedding are toxic to hamsters and can cause many different health problems), then it is ok. If you are using cedar or pine, get rid of it as soon as possible.
    As for the lump, this could be a tumor, abscess or just a growth. I would suggest having her checked by a vet.
    If you have anymore questions, please write again.

Thank you for writing!
