Does all cancer show in bloods?

Just that please.

I would say Leukaemia does yes, but for the others, some markers might be higher but you have to look for it.

Why do you ask?

[Kewcumber]

My mum's cancer never showed markers in her blood - I know because I asked at the Marsden.

[BlackSwan]

No. Brain cancer doesn't for one...

[Jemimapuddleduk]

No -my son's type of Leukemia (AML) did not show up in blood tests. Low platelets were identified but doctors thought it was ITP for several months. Only a bone marrow aspirate and trefine confirmed it.

No - my son had a grade IV medullabladtoma (very aggressive brain tumour) that did not show up in bloods.

What are you suspecting? What symptoms does your child show?

My daughter had ALL which didn't show up in the blood count. The next day they looked at the blood film and saw blast cells which confirmed leukaemia. A bone marrow biopsy determined the type.
