Hi, this was initially a question about if anyone else EGFR turn into small cell. I've decided to convert this into a journal of my dad's journey with his cancer. He was diagnosed with EGFR Exon 18 non-small cell lung cancer stage 4. He had a persistent cough that wouldn't go away. He thought it was just alergies for a month in 2018 and ignored it. in 2019, the same thing occurred, except the cough got worse. Finally, he decided to see a doctor and x-ray they discovered the 7cm tumor.
