Hi, I've just joined the forum. I was diagnosed with stage 4 lung and spinal cancer after a freak swimming pool accident where I banged my head on the bottom of the pool. I've had some complications with my immunotherapy and been hospitalised twice since my treatment started in January. Strange I know but my hair hasn't fell out but completely stopped growing. However, I am due my 4th chemo in 4 days and my hair has started growing again at a lightening rate. Had this happened to anyone? I can only take positives from it but don't want to count my chickens. Thanks and good luck everyone xx
