Functional lungs

I had my bi-annual pulmonary function test last week. The respiratory therapist told me that I’m now back in the normal range on all the measures, and based on the results, no one would have reason to believe that my lungs have any problems! The official results were uploaded to my patient portal over the weekend.

The percentage below indicates my result compared to the expected result for a woman my age.

FEV1 (forced expiratory volume) measures the air you exhale in 1 second.

  • Nov. 2023: 95%
  • May 2023: 91%
  • Oct. 2022: 73%

TLC (total lung capacity) is the total volume of air in the lungs after inhaling as much as possible.

  • Nov. 2023: 95%
  • May 2023: 83%
  • Oct. 2022: 72%
  • Jun. 2022: 69%

DLCO (diffusing capacity of lung for carbon monoxide, aka diffusion) is the extent to which oxygen passes from the lungs into the blood. It indicates the extent of lung damage and helps explain my shortness of breath on exertion and lower O2 saturation. I have improved 100% since June 2022, when I was first diagnosed with cancer.

  • Nov. 2023: 82%
  • May 2023: 68%
  • Oct. 2022: 49%
  • Jun. 2022: 41%

I will ask my oncologist and pulmonologist what they think most contributed to the improvement: cancer medication, reduced scarring over time, or ?? They've explained before that scarring (fibrosis) makes the lungs stiff and prevents oxygen from getting into the blood, so it seems like the scarring must be diminishing or the numbers would not have improved as much. But that's my armchair analysis. I imagine exercise also helps, but I doubt that's the main contributor.

It has been a tortuous path to get to this point, and I’m grateful that my lungs are finally becoming more functional. This morning was the first time I walked uphill from downtown to campus without my portable. I didn't have my pulse ox to measure my O2 saturation, but I felt ok. During our trip to the Rhine River Valley in late May 2022 (a few weeks before my diagnosis), I recall gasping for breath after just a short, steep climb up some steps. I complained to Leland that I had no idea menopause was going to mean completely losing any semblance of physical fitness. I can still envision where this happened, and would love to go back to see how that climb feels now.

We visited the Renwick Gallery of the Smithsonian American Art Museum in February, where we saw these glass lungs on display.

    Love to hear such good news! That is a beautiful sculpture as well. My son Gabe is learning about pulmonary functions in 7th grade science class. Makes me think of you. <3

    Great news! I think your hard work and fitness before and after diagnosis significantly contribute to your health today! Well done.

      Thank you, anonymous friend! We've been to DC countless times and have visited all the other Smithsonians, but had never heard of or visited the Renwick. We happened upon it by chance when walking by the White House.

    Dear Esther---Thanking & praising God for this amazing improvement, just over the last year and half!! And even if we can't always explain how or why the healing happens... to see such concrete ,visible proof of the healing that has occurred is so encouraging...whether it's in the numbers or walking up hills sans portable! Hugs & love from Maryland

    Wow! You are a high achiever in all arenas. How did this happen? You worked hard, followed protocols, consulted with experts, pushed when you needed to push and held back when your body needed you to hold back. I'm so glad that you are seeing tangible evidence that you are capable of healing; that's got to provide such comfort. Enjoy the upcoming break!

Healthcare costs and insurance woes and victories

Those of you who have read this blog from the beginning may recall my posts about how inexpensive healthcare is in Germany compared to the US. I now have additional proof. I've been receiving "explanation of benefits" statements from Aetna detailing the cost of my hospital stays and other healthcare services since the end of July. Close your eyes and guess how much these amount to. Higher. No, higher. Still higher. Well over $200,000. Of that, I have paid maybe $100 plus some $20-30 co-pays for doctor's visits. Add to that my cancer and blood thinner medications, which would cost about $16,000 per month without insurance. I have no idea what people in my situation do if they are uninsured or under-insured. My recent interaction with one of my German doctors illustrates another stark difference. Before leaving Germany, I had asked my doctor what to do if I received bills from the LungenClinic after we had moved and closed our Deutsche Bank account (all bills in Germany...

Indolent nodules

We met with my oncologist (Dr. Villaruz) and radiation oncologist (Dr. McCall) at UPMC in Pittsburgh yesterday en route from visiting family in Grand Rapids, MI. The main nodule we were watching grew by another millimeter or so. Dr. Villaruz described it as “indolent.” I asked what that meant and as she started to say “growing very slowly,” I recognized the word and blurted out “lazy!” I remarked I’d never heard indolent used in a medical context, and Dr. Villaruz said she’d never heard of it outside of medicine. So we both learned something. She and Dr. McCall said that there is no urgency, but that within the next 9-12 months, they would want to radiate the more clearly defined nodule and another one close to it. A third one looks like “ground glass,” a term for something that is hazy and not quite solid, but you can’t radiate something that is ill-defined and can’t be clearly imaged. It will be much easier to do radiation in the summer than during a busy semester or the winter b...

Four years

Sunday, June 14 marked 4 years since I was diagnosed with lung cancer while living in Hamburg. Those of you who have followed my journey from the start know that my family and I went to hell and back several times during those first six months. Here I am before, during, and after. The photo below was the last taken before my life unraveled. I went on a photography outing with the American Women's Club of Hamburg. When my doctor said my x-ray showed "infiltration" and I should get a CT scan, I put it off for a day so I wouldn't miss this event. That's how unconcerned I was. The possibility of cancer never crossed my mind, despite my severe shortness of breath. This was my hospital room at the LungenClinic, where I learned my shocking diagnosis. I was sitting at the little table with the doctors and Leland was on Zoom. Leland had to travel to the hospital by train (an hour-plus trip) before we could process the news together, shellshocked. This photo shows me in the...
