I went to visit to consultant: "pathology difficult - second opinion sought" and CT scan booked. Referred to haemotologist, and received the diasgnosis this week: "Follicular non-Hodgkins lymphoma".
Anyway, apparently I am lucky (really?!), as it has been identified at stage 1 (confirmation of staging following bone marrow biopsy a couple of days ago). Looks like I won't need chemo at this stage, but will need radio therapy, and there is a chance the treatment will eliminate it.
Still planning to have a go at the Clywd Gate on the 29th, if treatment hasn't started, and I am not advised against it by the consultant...
