My mum is on monitoring bloods at the moment, as her other bloods are ok they are not treating her. She goes to hospital every 8 weeks. Her pp is 33.5 at the moment and this has steadily risen from 18. They are not overly worried as the myeloma is not in her bones at the moment, they say her cancer is low scale. We are very positive about this and have been told unless her other bloods cause problems or there is a significant rise in her pps they will carry on and monitor. Im sure you mil is ok, as soon as the pps rise quite significant then i assume they will monitor her.
Positive thinking thats what my mum says. She was diagnosed with mm in 2009 and fingers crossed is doing ok .
Hope your mil is ok, take care Gina x
