Bump on the Head

Cutie cat woke up this morning with a big soft bump on her forehead and a little bit of blood at her left nostril, which is the same side as her tumor. The bump is soft and squishy so we suspect it's sinus fluids which can't drain out because of the growing tumor. I placed a call to the vet and am waiting to hear back on what to do. Bump aside, she's still purring, social, and eating well.
