Just diagnosed. Mom is in stage four!!!

Mom isn't feeling well. She feels that there is so much going on. She travels into town every week, twice. The kids and I went to visit yesterday, but she was in bed all day. She just isn't feeling herself. Today she was in and found out that she isn't eating the proper foods to get the warfarin to work. So now we add the dietician to her group of "prodders". She also has to see the surgeon who will perform the masectomy.
I was talking to her today. She is feeling better than yesterday, but still not great.
My poor Mom.

Mom met with her surgeon today. He said that her lumps and lesions are healing. Mom said he seemed surprised. Anyway, he is removing one breast. I told Mom to ask for the removal of both (as this is what she wanted), but instead, she didn't ask.
I want to tell her to stick up for herself!!! It seems to me that she should get what she wants. But she lets the doctors do all the thinking.
She is still excited about walking on her leg. We went to visit on Tuesday and she walked out to the kitchen, the other room, around the living room, then back to bed.
She is cold a lot lately. And she was getting nauseous last week too.
If anyone knows where that thread is, please let me know. I was looking around for an hour or more, but found nothing on it (although found lots of nifty other threads!!!)

Thanks so much!
It seems sometimes that I am always reading, checking out something or other. I was talking to Mom today and she wanted to have a masectomy, but the doctor originally told her it wasn't worth it. Then he decided that she needed a partial one, to remove the (large) lesion. When she met with the surgeon, he is taking the entire breast. She is happy with this decision, mainly because he made it.
Originally, she wanted to have both removed, but wouldn't bring it up with the doctor.
I have talked to her about it, but she refuses to ask and says he knows what he is doing.
Should I push it? Should I go for the next consult and ask for her (she wouldn't mind, as she isn't the one asking.) or should I just leave her be and accept her non-decisive decision making? I am so confused.

Her doctor is firm on the single mast. He told us (basically) that Mom was lucky she got chemo AND drugs. Usually they don't do both on a stage 4. I realize that he is speaking statistically about treatment, but to me, Mom isn't a statistic.
Can you stay indefinitely on Tamoxifen??? Everywhere I read, people are only on it for a definite period of time.

Mom won't change doctors. There is only one cancer treatment center in PEI and the doctors all work together.
I just pray that Mom stays strong.
It can be difficult here, not knowing anyone else dealing with this. I hate to burden my friends, and I don't want to steal Mom's optimism by talking too much about things. I talk to my husband, and he is very supportive, but does he have any advice, or experience in this? No.
This really sucks. Sometimes I think about those two years the doc promised Mom and think OMG! 1/8 of the time is gone now. Man, now I am whining. I hate it when I get upset about this.
I am going to bed. I will be cheerful again in the morning. I will just chant my "two days left with the students" song.
By the way, how long does a doctor normally wait before checking the size of mets tumors?
Mom gets a second cat scan in two weeks, but as for the bones, the doctor said sometime they will re-check. What in the heck kind of answer is that??????
Seriously, I have to go to bed.

Mom is set for July 6th for a "simple mastectomy". I don't understand why she isn't having lymph nodes taken out too.
I spent the day with her at the hospital going through all of the pre-tests. I was the noisy one, interrupting with questions, comments and information that Mom didn't ask.
I am glad I was there. I have to say that I am not happy that I know my way around the hospital the way I do.
This year has been quite challenging. Brenna, my (then four) daughter has a grand Mal seizure in Sept. Matt choked on a candy in October, I was diagnosed with hypothryoidism in November, Mom was diagnosed in March, and my Grandmother died in April.
One week and then Mom is in the hospital again. I am praying for her every day. She is a strong woman.
