Ok, I'm sure I should know this but what are Mets & micromets?

I see them on your posts all the time. I'm assuming it's a cancer cell but then sometimes I read people talking about them in regards to lymph node path reports. Again, I think they are refering to cancer cells but then when they say a micro met was found in a node I get confused.

Since I'm getting closer to surgery and lymph node dissection/ biopsy (one week prior to surgery) I think I'm starting to really think I have no idea what I'm reading half the time. I relied on my medical team for chemo since there really were no options there but now I'm realizing I need to be more informed going forward.

Thx- Eva

Re: Ok, I'm sure I should know this but what are Mets & micromets?

My understanding is that micro mets means just a small / minuscule ( micro) # of cancer cells have been found else where in the body ( metastisis ) this could be just in the lymph nodes alone or elsewhere .

Re: Ok, I'm sure I should know this but what are Mets & micromets?

I think Nurse4u2day has it right.

Keep in mind there's a difference between "metastasis" and "stage IV." Metastasis is cancer cells traveling beyond the original tumor. Micromets are tiny clumps of cancer cells found outside the original site. The first place they usually go is the lymph nodes.

I read somewhere that in postmortem exams, it's very common to see evidence of tiny little cancers. It's really not surprising that we get cancer. The surprising thing is that we don't all have it, and die from it. Living bodies are amazing.

4/29/11 CT scan shows suspicious lesions on liver and lungs
5/17/11 liver biopsy
5/24/11 liver met confirmed--Stage IV at diagnosis
5/27/11 Begin weekly Taxol & Herceptin for 3 months (standard of care at the time of my DX)
7/18/11 Switch to weekly Abraxane & Herceptin due to Taxol allergy
8/29/11 CT scan shows no new lesions & old lesions shrinking
9/27/11 Finish Abraxane. Start Herceptin every 3 weeks. Begin taking Arimidex
10/17/11--Brain MRI--No Brain mets
12/5/11 PET scan--Almost NED
5/15/12 PET scan shows progression-breast/chest/spine (one vertebra)
5/22/12 Stop taking Arimidex; stay on Herceptin
6/11/12 Started Tykerb and Herceptin on clinical trial (w/no chemo)
9/24/12 CT scan--No new mets. Everything stable.
3/11/13 CT Scan--two small new possible mets and odd looking area in left lung getting larger.
4/2/13--Biopsy of suspicious area in lower left lung. Mets to lung confirmed.
4/30/13 Begin Kadcyla/TDM-1
8/16/13 PET scan "mixed," with some areas of increased uptake, but also some definite improvement, so I'll stay on TDM-1/Kadcyla.
11/11/13 Finally get hormone receptor results from lung biopsy of 4/2/13. My cancer is no longer ER positive.
11/13/13 PET scan mixed results again. We're calling it "stable." Problems breathing on exertion.
2/18/14 PET scan shows a new lesion and newly active lymph node in chest, other progression. Bye bye TDM-1.
2/28/14 Begin Herceptin/Perjeta every 3 weeks.
6/8/14 PET "mixed," with no new lesions, and everything but lower lungs improving. My breathing is better.
8/18/14 PET "mixed" again. Upper lungs & one spine met stable, lower lungs less FDG avid, original tumor more avid, one lymph node in mediastinum more avid.
9/1/14 Begin taking Xeloda one week on, one week off. Will also stay on Herceptin and Perjeta every three weeks.
12/11/14 PET Scan--no new lesions, and everything looks better than it did.
3/20/15 PET Scan--no new lesions, but lower lung lesions larger and a bit more avid.
4/13/15 Increasing Xeloda dose to 10 days on, one week off.
7/1/15 Scan "mixed" again, but suggests continuing progression. Stop Xeloda. Substitute Abraxane every 3 weeks starting 7/13.
10/28/15 PET scan shows dramatic improvement everywhere. All lesions except lower lungs have resolved; lower lungs noticeably improved.
12/18/15 Last Abraxane. Continue on Herceptin and Perjeta alone beginning 1/8/16.
1/27/16 PET scan shows cancer is stable.
5/11/16 PET scan shows uptake in some areas that were resolved on the last two scans.
6/3/16 Begin Kadcyla and Tykerb combination
6/5 - 6/23 Horrible diarrhea from K&T together. Got pneumonia.
7/15/16 Begin Kadcyla only every 3 weeks.
9/6/16 Begin radiation therapy on right lung lesion that caused the pneumonia.
10/3/16 Last of 12 radiation treatments to right lung.
11/4/16 Huffing and puffing, low O2, high heart rate, on tiniest bit of exertion. Diagnosed as radiation pneumonitis. Treated with Prednisone.
11/11/16 PET scan shows significant improvement to radiated part of right lung BUT a bunch of new lung lesions, and the bone met is getting worse.
11/22/16 Begin Eribulin and Herceptin. H every 3 weeks. E two weeks on, one week off.
3/6/17 Scan shows progression in lungs. Bone met a little better.
3/23/17 Lung biopsy. Tumor sampled is ER-, PR+ (5%), HER2+++. Getting Herceptin and Perjeta as a maintenance treatment.
