Multiple meyloma with attached tumor?

[Dnmh]

I was wrong. In a presvious post, I said my mother had metastisized breast cancer. She had breast cancer has CLL & Multiple meyloma. She has some tumors in her hip bone and a few in a scapula. She's had a lump, now about the size of an egg cut in half, for about a year. She ignored it, thinking (hoping) it was only a cyst. She saw an oncologist the other day. He told her it was a tumor, and that it seems to be attached to a tumor in the hip and it has to come out. When she was first diagnosed, they told her the tumors were not getting oxygen at the time, but once they did, there was nothing they could do. She has to see a surgeon to have it removed and biopsied, as well as getting blood work, x-rays, bone scans plus an upper endoscopy & colonoscopy. My questions are: Why the digestive system tests? And, what does this all mean? I need to understand it so that I can do whatever I need to help her. The web has info, but it's all in medical terminology that I'm not understanding.If the tumor is attached to the hip tumor, does that mean it's getting oxygen? Her oncologist isn't telling her much.
Thank you in advance for your time.

I'm not trying to be pushy, I'm just afraid for my mom and need to understand what she may be looking at so I'm posting again to try and keep this near the top to get a better chance at getting some answers.
