Hi I have just been diagnosed with stage 3 melenoma it's spread from an original site from 8 years ago its now in the lymph node in my groin. I have my op on 22 August to remove all lymph nodes from the site and I'm so scared it'll spread before the op. I then start immunotherapy by iv drip. Has anyone got any experience of this and if it affected them. I'm worried as its a year and it'll affect me working
