Can high + ana (1:640 speckled/dense) neg for all ai diseases (lupus, ra, ctd, sjgrens) be something other than cancer? 5 mnths pp with 3rd baby, weird neuro symptoms started 1 week pp, extensive w/u (blood & imaging), all normal except ana & ebv.

ANA positive: ANA are common, sometimes 5 out of 100 individuals tested. There are far fewer people who have autoimmune diseases. That means there are many, many people who have a strong positive ANA who will never go on to have an autoimmune disease. See a rheumatologist. Your primary care doctor may also recommend a neurologist, depending on your specific symptoms.

Not cancer: High ANA suggests that you may be at a higher risk to develop autoimmune diseases but has nothing to do with cancer. If you have weird neuro symptoms, a neurology consult is likely indicated.
