I was diagnosed in Jan 2018 with NSCLC. At that time I noticed a horrible body odor when I awoke. The tumor was removed, I had 4 cycles of chemo and the smell went away. About a week prior to a normal MRI on my brain to ensure the cancer hasn't metastisized, I noticed my body odor has changed, once again. It has been confirmed the cancer has spread to my brain. I start whole brain radiation in a few days, followed by immunotherapy. In the interim, I must change my sheets every day as the odor is more than I can bear.
