I was diagnosed with stage 3 lung cancer in  late January this year and had a lobectomy in March.  Following this I have had lots of complications from chest infections, pulmonary emobolisms and general breathlessness; this delayed the start of adjuvant chemotherapy (Cisplatin and Vinorelbine) which eventually got underway 3 weeks ago.  I had some very serious side effects from this and as a result my oncologist has advised not to continue as the damage to my health would outweigh the benefits.   I asked him about the chances of the cancer returning and he has told me there is around a 40% chance of this.  I am devastated, I am 52 and was very fit and healthy with no symptoms of the tumour which was found by accident as part of a CT on my arm and shoulder.  What does the 40% mean in reality?  Are there any other people like me on here?  How do you cope with the uncertainty?  Should I seek a second opinion from a different oncologist?  Has anyone here had a similar experience and been offered an alternative treatment?
