Lab data

I developed malignant thymoma type B2 which was resected 5/2/2025. The median tumor doubling time for this disease is 381 days which brings me back to Feb 2021 at initial dose with tumor was 3.1cm with transcapsular invasion. I am a very healthy person with no pre-existing condition that would lead me to develop this extremely rare tumor. Please investigate whether these vaccines may have caused the tumor development. The thymus was enlarged to 56g and "TdT highlights densely packed immature T cells, and p40 stains nuclei of neoplastic epithelial cells. Lymph nodes non necrotizing granulomas and negative for tumor, differential granulomatous inflammation in lymp is sarcoid-like reaction to tumor or drug and sarcoidosis.
