Hello Sir,
I just wanted to chime in with my own two cents...
Currently, my wife is fighting stage 4 malignant melanoma. 27 tumors on her brain from the size of a walnut to grains of rice with tumors of all sizes in between. Then 15 tumors on her spine (including one about the size and shape of my thumb on her spinal cord at L1) Two on her left lung, three on her liver, two inside her chest cavity. She had an malignant melanoma tumor removed from her left arm along with two lymph nodes from under her arm in October of '21. She was declared cancer free a couple months later after biopsies found no cancer in the nodes, and clear tissue from the spot on her arm.
Fast forward to the first week of February of this year. On February 5th her world turned upside down. After her left leg could no longer support her standing or walking, an MRI revealed 7 tumors in the lumbar section of her spine.
Today: she has endured 10 targeted radiation treatments, a brain bleeding (stroke!) And is now on a medication that she will be taking the rest of her life. Not quite chemo, but a protein blocker that malignant melanoma needs to grow.
16 months ago, after an coughing fit and an MRI of her lungs, found the three "spots" on her lung. One so small, it can't be surgerically removed.
It was dismissed as nothing to worry about after monthly scans showed it was not changing, growing.
She has been hospitalized for 40 days as I write this. She is scheduled to come home on the 22nd. Wheelchair bound since while removing the spinal cord tumor nicked her cord, losing all feeling from the waist down.
So my take on a spot on the lung? Take it as a life or death revelation! Push, insist, demand, fight tooth & nail, to get those scans! PET, MRI, CAT, ULTRASOUND, GET THEM ALL! with contrast! Now, not later. You have had cancer already. It is very possible to be lurking, hiding, growing in hard to find places. Never assume for the rest of your (all of our!) Life, because you don't feel bad, you have nothing to worry about! My wife never had so much as a headache with 27 tumors attached to her brain. Please keep us, me, updated with your progress. You never know who's life you are saving, of course, including your own!
