Turn Scary Into Attainable

Nuclear Blue

2 Comments

Friday as part of my lumpectomy they took out two lymph nodes to check for any spread of the cancer. They are called “sentinel nodes” and are found via radiation. After they inserted a “localization” wire in my left breast to guide the surgeon to the tumor they took a couple of mammogram pictures, put me in a wheelchair with the images in hand, and pushed me down to Nuclear Medicine room #1. Rick took over once I was in that room and thoroughly explained each step that would be happening. He started with warning me yet again that I would be peeing Bronco blue for a day or so. The radioactive dye is tinted blue and it works its way out as blue urine – because Boise State is such a big deal in Boise everyone gleefully tells me I’ll pee BSU Bronco Blue as if I’m a Bronco fan (I’m a Boomer Sooner!) and somehow that will make it more normal.

He totally understands why so many people come through upset and tense but he enjoyed having me in there asking questions and looking forward to the future. I imagine it must be pretty bleak dealing all day every day with people who are facing uncertain or negative futures but Rick said he really liked his job and enjoyed learning new things all the time as the technology grew and changed.

The radiologist, Dr. Leymaster, came in and again warned me about the blue pee. I guess it must have freaked someone out at one point. Everyone along the way warned me – nurses, technicians, admissions people, doctors. Maybe they just enjoy talking about it. Then they had me lay down on the machine and the radiologist injected Lidocaine then the radioactive material – less than I will get when I fly to Seattle this week.

The radiologist left the room and the technician Rick pushed me under the imaging part of the machine. Since I was so interested in what was going on he made sure I could see the screen during the procedure and explained what was going on. The two big spots on the screen are the two injection spots just above and below my areola. Because this picture is so soon after the shots most of the radioactive material is still in the injection sites but will eventually work its way through my lymph system and out of my body – as blue pee of course. WP_20130906_031 The point though is to find the “first” lymph node or two that my breast drains to. The nurse explained that lymph nodes are like a pearl necklace – when you lay a string down in a clump it’s hard to tell where the “beginning” is. That “pearl necklace” is what is in the average armpit – a big mixed up mass of lymph nodes with no easily found beginning. The lymph fluid drains in a specific order, they are all connected with a single channel. The radioactive dye drains from the breasts in the same order as lymph fluid so where ever it goes first is where any cancer would go first. They can remove just the first couple of “sentinel” nodes and biopsy them – if they are free of cancer then the rest of the lymph nodes should be cancer free as well. After about 10 minutes Rick pointed out for me the small clump of radiation “above” the injection sites that indicated the fluid was clumping in a node – the first sentinel node. He then “drew” an outline of my body on the screen.

The radiologist came back in and used the Geiger counter along with the pictures to mark a spot in my armpit for the surgeon to remove the sentinel nodes. Rick had told me the machine would sound like R2D2 and in a way it did – as the machine got closer to the node with the dye it did beep and gurgle.

We finished up by looking at the higher resolution computer image and Rick showed me all the cool colors he could add to make the output more readable. We settled on green (of course!) for my pictures. The two biggest spots are still the injection spots and the spot just to the right and above is the node. The other dot further above is just an artifact of the process of drawing the outline of my arm – it is not a drainage spot. The line on the right is where he “drew” outside my rib cage and up under my armpit.

By the time of my surgery the dye had spread out a bit more but they already knew where the first node was. We won’t know for sure until the pathology results are back on Tuesday but the preliminary indications are that there is no cancer in the lymph nodes and I will be fine. And yes, I did pee blue the day after surgery….
