If each node enlarged almost overnight, that tends very strongly to being reactive. That's also true for many enlarging at the same period in time.
Altogether, I'm thinking you shouldn't worry much about cancer. Let me know what you find out from the hema, okay?
A CT scan mostly tells the place, size and shape if nodes. They want to see what's deeper inside. But a sonogram tells the inside structure of surface nodes. So you would e.g. want a sono before they'd do any biopsy.
I don't know how a problem in the lungs would affect the node areas you have. Granulomas would be expected to go to the neck though.
Now one more time :) Did the nodes each enlarge suddenly, either all together or one after another?
Well, I think you need more clues here, from testing.
That's a strange pattern for enlarged nodes. Did they each enlarge suddenly, either all together or one after another? How large? Can you tell if they are oval or rounded?
"varicose veins on my left breast/chest wall which the doctor is not concerned with"
If the enlarged nodes are on the left also, then to me that seems like a clue to not ignore.
Overall, my guess would be that this is reactive and not-cancer.
Any insect bites? Cat scratches? What is your age?
Might the nature throid have some impurity? Have you tried a different brand?
Okay then, that is "neutrophilia with monocytosis".
Some guesses:
Since it has been for years, it's not the 'acute' kind (AML).
CML (which is a blood cancer) would maybe/probably be a much much higher WBC.
If the 'expansion' (increased cell number) were in only one cell line, that's more worrying for myelonegenous leukemia than if it's in more than one line - which instead tends toward being reactive and not-cancer. Being reactive means responding to some influence, not simply runaway multiplying because of cancer. Even severe depression can increase neuts and monocytes.
Some drugs can do it. Are you on any medications?
Where are the nodes? Did they come up suddenly and then stopped growing? Have any been sonogrammed yet?
On your CBC report, what is the normal range for Absolute Monocytes?
Hi, your WBC is high because the neutrophils are high. Usually, neutrophils go high as their numbers increase to fight some infection. However since you are referred to a hema, you probably have no signs of infection and infection must have been ruled out. Probably ruled out, though there are 'occult' (hidden) infections.
Therefore, the hema will investigate other causes. At this point, it's not necessary to jump to the conclusion that it's the rare Neutrophilic CML - but unfortunately you probably will have to go through the testing and waiting to rule it out.
What are your symptoms?
