"Essentially Negative" PET scan result!!

Hi all,

I couldn't resist posting this. After a very long wait, I got the follow-up PET scan - 7 months after the first showed me lit up from pillar to post!! In retrospect I believe this was a false positive which someone mentioned on this board is common with PET scans particularly soon after surgery. I wish my doc would have told me this - though maybe he did not know how freaked out I was about this.

Anyway fast forward to present: Results are negative in all the previous lit up areas with some activity in my jugular lymph node which apparently has "brown fat" - so they will watch this.

I guess with all my talk, I am still dancing with NED!!! and I'm choosing to be very happy :)

Stay strong ladies!!

Congratulations on good scan results. Keep on dancing with NED! I plan on joining you soon. I will get a pet scan 3 weeks after I get my final chemo treatment. This will be my first pet scan as they have only done ct scans so far. I am a little nervous when I think about it... I pray that I will be dancing with NED too!

Celebrate!

That is great news about the PET scan. I too would choose to be happy. Dancing with NED sounds wonderful. I am hoping I can say that by the end of the summer, too. I am so happy for you. HUGS to you.

Dancing with NED!! WONDERFUL!

I've never been offered a PET scan. I think I will push for one after I finish my initial protocol July 1. How soon after radiation can you get a reliable PET scan? I thought I'd read that there can be false-positives as long as 3 months after radiation. The last thing I need is something FAKE to worry about, but I'd sure like to see if that tiny spot on my lung lights up onb a PET.

Anyway, CONGRATULATIONS on the great results! So glad you can set that worry to rest!!

I can't answer your question about time to wait after radiation. I didn't have any radiation. Best wishes on your treatment - you'll be dancing with NED soon too!!!!

I'm so happy for you and I'm sure that you're in cloud nine! I was offer to have Pet scan to check if I have any tumor marker on my lymph nodes but the insurance has turn down so the doctor has picked the cat scan instead. I read that cat scan gives more details than Pet scan?? Just curious what's the difference between pet scan and cat scan.

PET scan results up to 3 months after radiation. That is why she will do a CT scan on me first and then if it shows something she will do a PET scan. We certainly don't want any false positive results. I guess today was your last external radiation. Congratulations on finishing another step of the treatment. Hope the internal radiation goes well for you. I still am having nausea mostly in the morning from my radiation treatments. Not any diarrhea though, and can eat most fresh fruits and vegetables which I love. Hope you can go back to eating the fresh fruits and vegetables soon, too. Enjoy your time when you do not have to go for a treatment everyday. It is is strange after you have been going every day for weeks.

Hi all,

Thanks for the good wishes from everyone. It's nice to not be in active treatment.

After the big battle for the PET, my regime will be like yours Ro - first the CT and then the PET if there's a question. That's the only way my insurance will foot the bill.

Re: what's the difference? My understanding is the PET shows rapid cell growth - which usually means cancer and it can detect it in small amounts. I guess doctor's have their preferences and of course, Insurance companies play a big part too.

thank you

With the CT radiologists are able to see pictures of the body organs and detect abnormal tissues. But some times, esp after surgery and radiation treatment they can not say whether it is scar tissue, adhesions (two body parts attached to each other - happens frequently after surgery) or cancer. If they have any suspicion they order PET scan.

With the PET scan, they give you glucose which is attached to a radio-active substance. This will be absorbed in your body, and it will "light up" in the picture if it is absorbed too much in a particular area.
BUT it is not only cancer cells that absorb too much of this radioactive glucose. Any metabolically active cell will light up. Example: inflammation, infection, reaction to radiation treatment. So, with the PET scan they can not say 100% that this is a cancer, that is why the insurance companies do not always approve this expensive imaging. They can rule out that an abnormality seen in CT is not a cancer if it doesn't light up. But they can not rule in. They recommend not to do a PET within 3 months of radiation treatment because you have false positive results. My mom had increased uptake 6 months after treatment, and had a second surgery to biopsy this finding, and it was only scar tissue. It is a useful tool for the doctors but not a perfect tool. Hope this helps. Chrysoula

That really helps me, as I am anxious to have updated diagnostic imaging after my radiation ends July 1. That tiny 2.7 mm nodule on my lung that was noted on my April CT-scan will continue to worry me until I get confirmation that it is really the 'nothing' my oncologists believes it will turn out to be. I could see myself getting surgery like your mother did, just to get a definitive answer! That's probably not the wisest course, in retrospect, so I'll try to keep your cautions in mind. Thanks again.

dear all,

someone named hibi has gone back to 2009 and posted something re: a kind of shoe, sounds like an advertisement. it's been done multiple times and is confusing because if we don't look at the date the person before hibi posted, we think it's a recent one, when in fact most are over a year old! so, i reported these postings as offensive, and they've been flagged.

sisters,

at the risk of being redundant, i want to point out that several people here have responded in the last couple of days to a post mary ann wrote over a year ago, and is not a current one. the confusion in dates is because someone named "hibi" posted recently supposedly in response to a number of people's posts written in june 2009, so they all look as if they've just been written and are up to date, which they are not.

i hope this is helpful. won't post about this again in any case.

sisterhood,
maggie
