I'm a non-smoking 22 y/o male who's been through a battery of medical tests trying to find out what's wrong with me, and trying to figure out whether it is lung CA and what type it is or not.
If you'll bear with me, I'd like to share what I've had done so far. I don't really know anyone in my age group who is knowledgeable about lung cancer, so I don't really have a reference point for what to expect on the road to diagnosis.
1) Shortness of breath on even mild exertion (1.5 months)
2) Cough with white phlegm, occasionally yellow. w/ chest irritation (1 month)
3) Finger Clubbing (1.5 months)
4) Firm, fixed supraclavicular + posterior cervical lymph nodes (3.5 months):
-Supraclavicular lymph node: noticed in August 2016, was palpable but not firm/fixed; firm-ness gradually noticeable in October 2016 onwards
-Posterior Cervical Lymph node #1 (on side, mid neck) = palpable and moveable until December 2016, rapidly became firm and fixed
-Posterior Cervical Lymph node #2 (rear neck, where shoulder meets neck) = felt firm/fixed since September 2016, can feel progressively worsening shoulder/neck pain near it's location
5) Persistent fatigue (4 months)
6) Odd sharp pains in shoulder, back, and arms (1.5 months)
 Chest CTs: Please re-assess and comment on abnormalities like the GGO or lesions. Changes between two test dates as well...

 Neck MRIs: Concerned about lymph node growth between Two Exam Dates especially in Left Supraclavicular region, Left Posterior Base of Neck general area. Please also comment on any other lymphadenopathy if spotted

Late September 2016 -- First noticed "hardening" of left supraclavicular lymph node. Size is about 1cm.
October 2016 -- Got the node checked out, both primary doctor and ENT can't really palpate it so they didn't order biopsy. Said to wait on neck MRI. Meanwhile, paranoid me went on Dr. Google and found the infamous "Virchow" node and worried that it was a signal of stomach cancer
. So we did a upper GI endoscopy, which came back clean.
Early November 2016 -- Neck MRI results came back, radiologist report doesn't mention any node enlargement, so doctors even more adamant to not biopsy. I got an Abdominal MRI and MRCP, which came back negative. Supraclavicular node still there.
Late November 2016 -- Suddenly developed shortness of breath on minor exertion. Noticed fingers were Clubbing. Didn't respond to inhalers, so got referred to pulmonologist. Did Chest X-Ray and HRCT, both came back clean. Full autoimmune disease panel also came back negative. Pulmonary Function Tests came back with reduced diffusion and Restrictive Lung function...unexplained by tests.
Only abnormal things were in the blood tests: D-Dimer, Inflammatory markers (CRP, ESR), and some Blood Cells (Monocytes, Basophils) were moderately elevated.
Late December 2016 -- Shortness of breath, Clubbing still present. Newly onset cough. Had repeat Pulmonary Function Tests, which showed worsening of lung function...still without determinate cause. Blood results still abnormal, gradually worse. Got repeat Chest CT with Contrast this time...had like 3 different radiologists read it. One of them found a "mild geographic ground glass opacification" on my left lung. No evidence of any lung "masses" though, according to the reports. I went to get a second opinion from a different pulmonologist, who said that the ground glass thing was a very subtle finding that was also very nonspecific.
January 2017 -- Clubbing is worse. Doctors can still barely palpate the lymph nodes. We did a Neck CT w/ Contrast that showed multiple visible but subcentimeter nodes. Also in the neck there was some "mild, ill-defined soft tissue stranding", which as you might have guessed, again is very non specific.
Present -- We decided to go for it and order an Ultrasound-guided Core Biopsy of any Neck Lymph Nodes that we could get. Getting that done next week, and that might give us some answers.
With my symptoms and past tests ruling out benign causes, it seems that the only differential diagnosis possibility is Lung Cancer. I'm just frustrated that I have some sort of "invisible/massless" or rare but metastatic Lung Cancer of some kind.
---In your experience, have you ever encountered anyone with a strange symptom presentation like this?
---Are there any rare subtypes of Bronchogenic Cancer that present in this manner?
---Are there any other tests we can do to determine the cause?
---As for the Core biopsy of lymph nodes, what information can we get from it? Possible to do genetic/mutation testing on it?
