This month we're talking about chronic cancer. Chronic cancer often can't be cured but it also may not need treatment immediately. Sometimes, they can be treated long-term, or they might require treatment every so often.  Myeloma, some lymphomas and leukaemias and even some ovarian cancers can fall into this category, but they're often not well understood by friends and family (or people in general!). Tatum talks to David, Lucy and Kerrie about their experiences.
