I am her2 and after 10 years, spread to bones, liver, lung and pleural. got the blood test of her2 serum level result today and is elevated to 22ng/ml (15ng/ml is the normal cutoff value).
Is it possible to have her2 negative at the primary tumor and then change to her2 positive? anyone has similar experience?
How will this affect the treatment plan?
