Hi, my mum has advanced lung cancer (NSCLC), spread to spine and lymph nodes when diagnosed last year. Recently we found out it has spread to the brain and adrenal glands. She's gone downhill so much in the last couple of weeks. Very breathless and weak. The change since last month is heartbreaking.

She was in hospital last week (oxygen v low), they also discovered severe electrolyte imbalances. She's on the edge of diabetes (probably exacerbated by the steroids) but they're also concerned about low sodium. Does anyone have a clue what's going on? I know the prognosis isn't good, but I'm very alarmed by the sudden deterioration. It seems like her whole body is ceasing to function properly.
