9 month old rat has tumour ?!?!?

  My ratty has a lump under her armpit that I am sure is a tumour. Have booked a vet apoinment but why has she got a tumour so young?: (

If she get's this one removed, could she ever get another? I do not want her to suffer the operation twice ....
These are very common. At her age she is already middle aged for a rat. Yes, she can definitely develop more tumors in the future ... there is no way to know this or guarantee she won't.



Here are more details on tumors:
