Bone scan for density vs. mets (need info)
I am scheduled for a bone scan this week to check for bone density. Is this the same scan that is done to look for mets? If so, is it necessary for me to ask those running the scan to look at the results for both, rather than at density alone. If it is not the same test, does anyone out there know what the difference is between the two?
Any information would be helpful. My scan is on Friday. Thanks as always for help.

If you are having a bone scan, it is a test that is checking for mets to the bones and is completely different than a bone density test. With a bone scan you are injected with a radioactive dye and then scanned.
A bone density test checks for osteoporosis and not mets. A bone density test can be done at your primary care physician's office if he has the equipment (mine does) and takes about 3 minutes. With a bone density test you just sort of lay on a table and certain areas of your body are measured by a machine - no dye is injected and you are not actually scanned.

You do not get a bone scan for density (ie: osteoporesis) you get a bone DEXA scan which is a very different xray.

Ditto, Becky. I have bone density tests for density and bone scans to look for mets. Different tests.

Nov'03~ dX stage 2B
Dec'03~ Rt side mastectomy, Her2+, ER/PR+, 10 nodes out, one node positive
Jan'04~ Taxotere/Adria/Cytoxan x 6, NED, no Rads, Tamox. 1 year, Arimadex 3 mo., NED 14 mo.
Sept'05~ micro mets lungs/chest nodes/underarm node, Switched to Aromasin, T/C/H x 7, NED 6 months - Herceptin only
Aug'06~ micro mets chest nodes, & bone spot @ C3 neck, Added Taxol to Herceptin
Feb'07~ Genetic testing, BRCA 1&2 neg
Apr'07~ MRI - two 9mm brain mets & 5 punctates, new left chest met, & small increase of bone spot C3 neck, Stopped Aromasin
May'07~ Started Tykerb/Xeloda, no WBR for now
June'07~ MRI - stable brain mets, no new mets, 9mm spots less enhanced, CA15.3 down 45.5 to 9.3 in 10 wks, Ty/Xel working magic!
Aug'07~ MRI - brain mets shrunk half, NO NEW BRAIN METS!!, TMs stable @ 9.2
Oct'07~ PET/CT & MRI show NED
Apr'08~ scans still show NED in the head, small bone spot on right iliac crest (rear pelvic bone)
Sept'08~ MRI shows activity in brain mets, completed 5 fractions/5 consecutive days of IMRT to zap the pesky buggers
Oct'08~ dropped Xeloda, switched to tri-weekly Herceptin in combo with Tykerb, extend to tri-monthly Zometa infusion
Dec'08~ Brain MRI- 4 spots reduced to punctate size, large spot shrunk by 3mm, CT of torso clear/pelvis spot stable
June'09~ new 3-4mm left cerrebellar spot zapped with IMRT targeted rads
Sept'09~ new 6mm & 1 cm spots in pituitary/optic chiasm area. Rx= 25 days of 3D conformal fractionated targeted IMRT to the tumors.
Oct'09~ 25 days of low dose 3D conformal fractionated targeted IMRT to the bone mets spot on rt. iliac crest that have been watching for 2 years. Added daily Aromasin back into treatment regimen.
Apr'10~ Brain MRI clear! But, see new small spot on adrenal gland. Change from Aromasin back to Tamoxifen.
June'10~ Tumor markers (CA15.3) dropped from 37 to 23 after one month on Tamoxifen. Continue to monitor adrenal gland spot. Remain on Tykerb/Herceptin/Tamoxifen.
Nov'10~ Radiate positive mediastinal node that was pressing on recurrent laryngeal nerve, causing paralyzed larynx and a funny voice.
Jan'11~ MRI shows possible activity or perhaps just scar tissue/necrotic increase on 3 previously treated brain spots and a pituitary spot. 5 days of IMRT on 4 spots.
Feb'11~ Enrolled in T-DM1 EAP in Denver, first treatment March 25, 2011.
Mar'11~ Finally started T-DM1 EAP in Denver at Rocky Mountain Cancer Center/Rose on Mar. 25... hallelujah.

Hi Grace,
I had annual bone density testing done and mets did not show up. Over the years I assumed that the density test would show mets. I found out it does not.
The bone mets I have were found via bone scan / CT / PET. I asked why they had not been found in the bone density testing and was told that bone density testing only measures density. Still not sure why and I haven't googled it.
I am sure that someone will chime in soon with the scientific answer.
Carolyn

I will make a fool of myself for sure, but here goes. I believe that bone density tests are an X-ray designed only to measure calcium and mineral content. Bone scans are nuclear medicine tests with contrast that can detect fractures, cancer, infections and other abnormalities in the bone.

Thank you all.
I woke up last night about 3:00 a.m., obviously this has been on my mind, and thought I'll ask the HER2+ group--they'll know. And, of course, you did!
Thanks all.
