Cancer Support

My mom was diagnosed in 00 with stage 3 breast cancer,had her lymphnodes removed,numerous surgeries,chemo and radiation and was in complete remission.In 05 she was diagnosed with metastatic cancer in her lungs and started chemo but contracted a blood infection at the hospital during a procedure to put in a Hickman’s catheter so she had to quit chemo for 3 months b/c the antibiotics they had her on were so strong the chemo wouldn’t be effective.Three months after going back into chemo she was told she was once again in remission,only for the doctor to call back literally 5 minutes later and tell her that her test results came back and she AGAIN has more nodules in her lungs.More invasive chemo treatments were put it order.All but one nodule in her lung is gone,its not getting any smaller but not getting any bigger so they’re keeping an eye out.Just in Feb. she was diagnosed with bone cancer in her hip. She just finished radiation last week and starts chemo very soon.Pls read details….
I know that no one here can tell me how long she has to live because I don’t think God uses Yahoo, lol. She has been a very strong woman in the past 7 years working full time through all of her treatments. I know even though she puts on a strong front and acts like everything is okay, inside she is scared to death (no pun intended) and has to be wondering why it keeps coming back. My question is, how likely are the treatments to work to shrink all the legions on her hip? Being that it is metastatic and has gone from her breast, to her lungs, to her hip, it will probably just keep spreading. Does being on chemo really help cancer from spreading? It spread while she was on chemo the past 2 years, so does the chemo only treat the cancer she was diagnosed with in the first place? (ie: treated with lung cancer so it wouldn’t treat the bone cancer…) We are all being very strong and support her in every way we can.
*I meant diagnosed with lung cancer so it wouldn’t treat th bone cancer.
