Naga and the team are joined this month by Darlaine Honey, who was diagnosed with lobular breast cancer and is a co-founder of the group Lobular Breast Cancer UK, and Professor Rob Clarke, who is professor of breast cancer biology at the University of Manchester and is leading the Lobular Moonshot project to find an effective treatment. Lobular breast cancer makes up around 15% of all breast cancer cases in the UK. Unlike Ductal Breast Cancer, lobular grows in a line or as single cells and rarely forms a lump so it’s much harder to spot. That Time of the Month, part of 5 Live’s Me, My Health & I series.
