Cameron gives Elyce what I'm guessing is a mammogram. I've never had one, being way below the age that they start being a recommended thing to do and also having no family history of breast cancer to worry about. But most importantly, not having health insurance. Damn you Canadians and your universal health care, which despite having its own unique set of problems, is still preferable to not having coverage at all! ["Not to brag, but it is a pretty sweet deal." -- Wing Chun] Elyce doesn't particularly enjoy her mammogram, pronouncing it painful. Has she never had one before, despite being in her mid-thirties and having a mom who died of breast cancer? "I'm sorry!" Cameron responds, making a few of her best sympathy faces. Then she does whatever it is that you do to perform a mammogram, and I'm pretty sure people go to school for and train to be mammogram techs, but it appears that Cameron's going solo for this one. Once it's done, Elyce sighs that she wanted to have kids, but it looks like she won't be able to now. "A lot has changed since your mom died," says Cameron. Well, sure, but I'm guessing that you still can't have a baby if you're dead, which is probably Elyce's main concern right now, shut up Cameron.
The mammogram reveals only benign calcifications, which don't sound like fun but are not cancerous. Wilson says the tumor is probably just too small to detect, and that they should do a PET scan to find it. In 12% of cases, there is no tumor at all. Chase is confused; how can someone have a disease caused by a tumor when there is no tumor? Wilson's answer is "it happens." Chase asks how they're supposed to treat it, then. House says you don't; the patient dies while his doctors look for a tumor that isn't there. He tells them to treat the Elyce's symptoms while they wait for the tumor to get bigger and easier to find. Meanwhile, someone needs to check out Elyce's workplace, just in case she doesn't have paraneoplastic syndrome and is having a toxic reaction. It won't be in her home, since the husband is healthy. Is he, though? In the beginning of the episode, he did say he was tired.... Anyway, House assigns Foreman to work-toxin-detail.
House and Foreman exit the elevator on the way out of the hospital and home. Well, House is going home. Foreman gets to go sniff the carpet at Elyce's workplace. Foreman demands to know why House has been "riding" him lately. House simply says that if he's been on Foreman's case more than usual, then it can't be a race thing, since Foreman is "just as black" as he's always been.
