Had an emergency at the end of winter, ER doctor took a CT scan and saw a Nodule on my left lung at the bottom and also saw inflammation at my sentinel lymphoid. Strongly suggested I get a PET scan. Went to my regular doctor (who is an Internist) he arranged for Scan. Went fine. A different doctor read the scan. Told my doctor that there was no cancer anywhere. (He told me). Anyhow this Radiologist compared the PET scan to the CT scan done 2 weeks before at Emergency RM, not the CT scan done a year ago that showed a 11cm nodual. (Of course no change. Would something really change in 2 weeks?? That raised my eyebrow)
Anyhow here are my questions:
1. will a PET scan show ALL cancers in the body?
2. Is there a blood test that would show cancers?
(It really amazes me that I just sit and wait for it to visually show itself to my dermatologist.)
PS: I should also add that I have Transverse Mylitis (TM). I am waiting for Melanoma to metastasize. I had one spot removed. 7 out of 9 siblings (and me) have cancers. (One brother has had 4 cancers and is still alive after 6 years).
Thank you in advance for any advice/help you can give.
