Linda Nolan has written an emotional open letter to Sarah Harding following her revelation that she is battling advanced stage breast cancer. The 61-year-old Nolans singer has been diagnosed with incurable liver cancer - the third time the illness has returned following her initial breast cancer diagnosis in 2006 and a secondary cancer on her pelvis in 2017 - and in the wake of Sarah's brave health admission last week she has offered her support to the former Girls Aloud member.
