joelars – I understand more now. Thank you for going into more detail. ANY diagnostic test is not 100%. My first tumor was picked up by an Xray. Also if your doctor isn't a positive about the anomaly that he picked out then a follow-up CT might be needed.
If a doctor gives you news that is not to your liking then you must follow it up, of course. After my first cancer I went all out with exercising. Don't you think that your welfare should be put before your desire for high intensity work-outs, not matter how good they make you feel?
