Following on from the last panicked posting, MW is in hospital having tests. We have been reassured that there is no cancer in her bowel. There appears to be a bone infection which is being investigated by means of a bone biopsy. A quick Google search tells me that an extended course of antibiotics is the order of the day.
MW will also undergo a partial colonoscopy to investigate another bowel issue but it’s not tied to cancer.
I can breathe again. Slowly.
