I have a 7 year old beagle, she's had a lump appear and disappear in the same spot just below her rib throughout a few years, she's probably had it for the 5th time now. But the first few lumps were movable, soft feeling. this time the lumps is bigger, hard and more lumpy and Im really concerned! Do you have an idea of what it could be? And is it lifethreatning? I dont want to lose my baby girl!

That could be due to a mastitis (infection of the mammary gland) or possibly the tumor could have turned not benign anymore.
This kind of lump/growth needs to be ideally assessed by your veterinarian to have a definitive and specific answer. Usually there are two ways your vet can do that a part from examining it directly during physical examination. A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration).
The biopsy usually give definitive/reliable results.
Chest x rays may be needed as well in case of a tumoral growth.

It could be a mammary gland tumor. It's concerning that it keeps getting bigger every day. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Give Alice's vet a call to make her an appointment. Best of luck.
