Help PussPuss Fight Mammary Cancer!!

Hi everyone im not an english native speaker, so sorry about some of the weird words or the way I describe something. Here is my beloved PusPus. She is 10. She spayed when she was around 2. Exactly 3 months ago I found 2 lumps around her belly, one lump that was close to other weird mass, and one lump that is far from the first lump. She got xray and bloodwork before, it showed no serious thing about the lumps but vet told me to keep watching it as if it may grow bigger which one of it did. One of the lump attached with the weird mass located under her nipple seems swollen, and other lump remain same size. It doesnt look big but when it rubbed it quiet deep.

Went to vet this morning and did FNA, they found abnormal cells which Im pretty sure it leads to cancer. Here is the recent bloodwork result which shown she has some infection inside. She has no symptoms at all, eat like a pig, play and nap well. She is staying at the vet today to do an xray to see if the cancer has spread. We will do a surgery (removing her infected mammary chain) on Wednesday meanwhile she will be in antibiotics. Im so worried about her and just cant stop crying, cant even accept why she has to go thru this. I need some positive stories or maybe some suggestion on vitamins after surgery. I gave her naturvet mushroom max for the last 2 months and I hope it works to slow the cancer to spread.

Unfortunately, I dont make much and Pusspuss will need a lot of stuff for her surgery and after her surgery.

As she will needs around $400 for her surgery (not include the boarding at the vet, could go around $600) and she will need more vitamins, meds after the surgery and maybe in the future will need her other mammary gland chain to be removed as well
