I am giving Leslie the benefit of the doubt on some of this. Yes, it absolutely sucks that Stacy went back to work so quickly after giving birth. early on we were told that she works part time in her family's business, so they can probably be more accommodating to her. Also, given that it is her family's business, that is where the idea of her being able to pick up more hours (aka the family will help you out some; that is, unless they had already been hoping she could work more) would make some sense. It would be so much better if they were financially secure enough for Stacy to take time to be home with the baby. Unfortunately that is not happening.
Leslie lost her job. I would expect that she has applied for unemployment and is most likely looking for a new job. Unless Leslie had to go into the unemployment office to apply and there was a chance that someone there would balk at her gender, the show wouldn't focus on that. So we're not going to hear about it. For them to film any job interviews, the hiring company would have to agree to filming and Leslie would have to explain why she was being filmed - not a good way to start things off.
With the medical stuff, we are definitely missing some components in the story. If the endocrinologist leaped from bleeding nipples to remove tissue, that would be very odd. It may be that among this group of doctors the surgeon would be the one to order a mammogram, ultrasound, etc., then determine whether to do a biopsy. The endo referred her to a surgeon. When they say she has abnormal cells she either had a biopsy (I would expect to have heard that word if one was done) or she had the mammogram, etc. that showed an abnormality. She is now going in for the biopsy; they may have decided to remove all of the abnormal appearing tissue as part of the biopsy.
Years ago this would have meant knocking her out and doing this in an operating room. Now this and many lumpectomies are done in surgeon's offices; while it is less scary than going under, it is still scary. To my mind, she and Stacy have every right to be concerned. I haven't heard her say she has cancer (She's no Betty Jo on My 600 Lb Life). I have heard both Leslie and Stacy express concern that they don't know if this is a setback or a major issue. Her saying she wishes Stacy could be there with her seems reasonable to me. I would rather have a partner with me than go alone. She followed her comment by saying it was important that Stacy be home to take care of the kids. Sounds reasonable to me.
The show is playing up the drama - it's life-threatening! This is reality TV gold!
Depending on the nature of the cells, even if they are not cancerous, it could mean she cannot tolerate hormone therapy. Not physically life threatening but certainly emotionally difficult.
Stacy and Leslie are stuck in a way. They are getting paid to be on reality TV. They are not being paid enough to take care of all financial issues, but it's not money they can afford to throw away. Got to film when asked. At the same time, they need to work on a plan to get out of their financial hole. And I do mean they. While too much is falling on Stacy in their current situation, they decided to have a second child. They have been in a financially precarious situation for some time. They were already hunting and fishing to supplement their food budget. They represent the working class - living, working and trying to make ends meet - a situation in which one person losing their job quickly becomes critical. They are among the many who do not have a large rainy day fund to fall back on and are now being met with additional expenses.
If things go well, Leslie's procedure and tests will go okay. She'll find a new job and they'll be able to stabilize again. But that might take more than a minute, especially if she has to get through filming before she can really commit to a new job. It's hard to start then say, "I'm gonna need these days off, then this afternoon, then . . . . " It is also hard to look for a new job when you have a medical concern. Again, I just started but I need time off for . . . doesn't play well.
