Hi, my 37yr old best friend has today been contacted by an NHS lung cancer specialist nurse who gave my friend the strong impression that she has lung cancer; nurse used phrases such as "The mass on your lungs", "You're so young", "Call anytime for support on your journey" etc... My friend has not been contacted by a doctor or specialist/consultant to discuss a diagnosis of cancer. She had an x-ray some months ago and was advised she has a shadow on one lung, and likely this was a chest infection for which she was prescribed antibiotics. Her symptoms continued (shortness of breath, cough) and she went for an MRI/CT scan. She has been advised by the nurse that a shadow is now also on her other lung. The nurse said my friend needs to have a breath test, and another scan which can take up to 30 mins to perform. My friend is devastated following the conversation with the nurse (who was very nice), she feels she must have lung cancer, hence why she is being contacted by the lung cancer nurse. My question is - would she need a biopsy in order to determine whether or not she has lung cancer? Can a diagnosis be made without a biopsy? Could the shadows on her lungs be something else other than cancer given her age? Thank you for your time.
