On April 21st I had a core biopsy and today I was told that I have mucinous carcinoma of the breast.  When I investigated on this website, the information given was that this is a rare type of cancer, about 2-3% of all breast cancers and usually occurs in post-menopausal women over the age of 60.  I am neither.  I am 51 years old, but still menstruate.  I have an appointment with a surgeon, but feel as though I am in the state of shock.  This "nodule" was found on routine mammogram and I convinced myself that it was nothing.

This may sound odd at my age, but I just recently started to enjoy and like 'these babies'.  The thought of losing my breast scares me tremendously, and I have not even considered the thought of this cancer metastasizing.  I won't think of that!

Hi everyone, Thank you again so much for all the valuable information shared here!

I just wanted to update my most recent discovery, because this might be relevant to some here too. As I wrote in my previous post, I have MC (ER, PR positive, HER2 negative, LN negative, size 2.7cm, grade intermediate) and got lumpectomy in May. In pathology report based on my core biopsy, Ki67 was <5%. However, my mammaprint test was at the lower end of the "high risk" category and Oncotype Dx result came back with 14. Since all those numbers did not match up for me, I requested a meeting with my pathologist, whom I had never met in person. It happens one of the pathologists at my institution runs a program called "Ask Pathologist"and agreed to meet with me. He went over all the slides from my lumpectomy and explained how pathologists "read" the images. It was extremely helpful and empowering to actually see my cancer cells (with much mucins...) under microscope and understand what's going on. During the session, the pathologist actually pointed out that the slide near the site where core biopsy sample was taken was not necessarily representative of other slides (It was visually a less active site.) So I asked him if it's recommended to request Ki67 data using a sample from lumpectomy. He didn't think it would be too crucial for my treatment, but he did agree to request another report. The result just came back and says my Ki67 was actually 25%, which is actually considered to be high --my understanding is that this is again at a lower end of the "high" category. My oncologists say that they still don't think chemo is necessary for my case. One of them said that Oncotype Dx test does include data based on five or six genes (sorry I cant' remember the exact number) that relate to proliferation of tumor cells. Ki67 is only one of them. So according to him, we could still base our understanding of the tumor on Oncotype DX test and Taylor X study.

From a patient's perspective, however, it was really helpful to get the new Ki67 number, partly because from the very beginning the old number was referred to a lot as a proof that my tumor is really slow. It is actually helpful to know that my tumor is not that slow after all. Also all the numbers finally seem to match up for me. (I wish Oncotpe Dx test result makes more details available, including their result for Ki67 and data on other genes linked to proliferation.) Since I'm also pre-menopausal, I'm still exploring a possibility to get both tamoxifen and ovarian supression -- I'm meeting with my oncologist this week on that. She's actually recommending to stick to tamoxifen in my case and I'll find out why she thinks so.

If any of you have any similar experience or any feedback, I'd be so grateful!!

Thank you so much.

Noraneko, thanks for your sharing. I've read some article that mention expression of ki67 in tumor is heterogeneous, biopsy may not reflect 100% how is the ki67. That's also what we find in your case.

I am curious why you consider ovarian suppression? Is it suggested by your oncologist?

Hi, Noraneko, annhkg, that's similar to my case.

Ki67 measures the proliferation of the cancerigenous cells on tumour margins, and as well as tumour grade, it IS heterogeneous along the tumour. That is why is so important to have another test done over the whole tumour after surgery, the bigger the tumour is, the most important. Mi fine needle biopsy, which took a tiny portion of tumour, showed up a 10% proliferation rate or Ki67 and grade I. I was going to get my oncotype done, to decide wether or not have chemo.

Then the whole tumour biopsy was done, and it came up with a 30% Ki 67 and grade 3, because the cancer cells were growing faster and were poorly diferenciated in some other places of the tumour (mine was big, 3.8 cm, and multifocal, I had 4 nodules). This agressivity is what sets the agressivity of treatment, as well. So I am now in the middle of my chemo treatment, and my oncologyst decided to skip the oncotype.

About hormone therapy and ovarian supression. I am 42. I dont want to do the ovarian supression. I suffer from chronic back pain and Im quite sure the supression would make it worst. From my last hormone testing I can see they are naturally slowing down their function. So I have to discuss it carefully with my doctor. I think tamoxifen would be enough.

Hi Monica,

Sorry to hear that you have to go through Chemo, it must be tough moment. Wish you don't have too much SE.

My BS also suggest only Tamoxifen to me, and I am now on Tamoxifen around 9 months, with 6 months regular checking on endometrial and uterus. And I have just asked my GN about ovarian suppression, he don't really suggest as many problem will come out if we stop the ovarian function too early, I think what you mentioned about back pain will be one of the problem after ovarian suppression.

Hi annhkg and Monica,

Thank you so much for sharing your cases. It's so helpful to read all the information about Ki67.

As for ovarian suppression, my oncologist is *not* recommending it to me. She thinks it's best for me to stick to Tamoxifen, but she's still leaving the ultimate decision up to me.

She gave me those two articles to read:

"Adjuvant Ovarian Suppression in Premenopausal Breast Cancer" in NEJM Dec 11, 2014

"Tailoring Adjuvant Endocrine Therapy for Premenopausal Breast Cancer" in NEJM June 4 2018

The second one is a recent follow-up of the first study. (I tried to paste links, but it seems like I'm not allowed to post links on this forum? If you google the titles, you get direct links to the articles, though.)

I brought up the possibility of doing ovarian suppression to my oncologist, because I worried about the fact that I'm pre-menopausal at the age of 52. The Tailor X Study ("Adjuvant Chemotherapy Guided by a 21-Gene Expression Assay in Breast Cancer" that also just came out in NEJM) says that:

"A total of 40% of women who were 50 years of age or younger had a recurrence score of 15 or lower, which was associated with a low rate of recurrence with endocrine therapy alone. Ex- ploratory analyses indicated that chemotherapy was associated with some benefit for women 50 years of age or younger who had a recurrence score of 16 to 25 (a range of scores that was found in 46% of women in this age group). A greater treatment effect from adjuvant chemo- therapy has been noted in younger women,7 which may be at least partly explained by an antiestrogenic effect associated with premature menopause induced by chemotherapy.27 We did not collect data on chemotherapy-induced meno- pause. It remains unclear whether similar bene- fits could be achieved with ovarian suppression."

So I wanted to make sure that I really do not need chemotherapy or ovarian suppression, despite the fact that I'm heavily menstruating... (My pathology report from the surgery also indicates a small possibility of LVI etc. So I also wanted to make sure that I'm not under-treated.) My oncologist told me that she put my case on cancer board and five oncologists agree that I don't need chemo.

I'm finishing my radiation therapy this week. So I'm starting tamoxifen and see how I react to it. I still need to finish reading the two articles on ovarian suppression that I quoted above, but at this point I'd be most likely to do what my oncologist told me to.

Hi all, I have just been diagnosed with mucinous carcinoma of the breast, there are at least 2-3 areas, I think 2 about 20mm or a bit smaller, one smaller still (not biopsied) and one lymph node. After the initial feeling of relief at being told the prognosis is usually good for this type, I am slightly worried that the initial pathology report didn't seem to contain much info. It seems to indicate pure mucinous and I know it's multi-focal, ER+ but no idea about PR and think we are still waiting on the HER test. There was no info on the rate of growth of the cells either?! As such no grade has been given. I understand that typically mucinous carcinoma is less likely to travel to the lymph nodes but yet I definitely have at least one lymph node involved. Naturally this makes me panic that mine is a more aggressive and fast growing type. Step one is mastectomy (as I understand it due to the cancer being multi-focal, i.e. in several different areas) and once they have analysed what has been removed we will have a better idea about next steps. I am 44, so again, not as old as the stats suggest. Anyway I look forward to sharing my experiences on this board and hopefully add to the picture of this type of BC.

mrsfingers....welcome aboard our journey. Many of us here were young, or youngish when we were diagnosed. Please be sure to ask that you have genetic testing including the OncotypeDX test. Once you have the final surgical pathology report, if there are any answers left out or borderline results, ask for a second opinion.


Keep us posted. We are here for you!


And lastly, register at the NCCN website and read the professional version of the breast cancer guidelines. Specifically note the page on Tubular and Mucinous breast cancer. Knowledge is power

It was here, through the footprints of previous members, that helped make my journey easier..so I am trying, with the help of others, to make your journey a little bit easier....paying it forward...

Thank you for being here. You all have a wealth of information and I am just now digesting it.

Thank you. This is a group I kinda didn't really want to join! Just to re-cap...Biopsy on 8/20, got THE call on 8/23. Saw a wonderful breast surgeon at a large teaching hospital in Phila. the next day (thanks to my daughter-in-law who's a physician with an oncologist father!). Surgeon spent almost 2 hours explaining things to me and my options. I am Stage 1, PR+, ER+, HER2-. Oncotype DX to be done. I have 2 separate sites in L breast with micro-calcifications scattered between. Plastics appt is 8/30. Option 1 is, of course, mastectomy with TE. Option 2 is a lumpectomy. The issue with Option 2 is the amount of breast tissue that will need to be excised and whether or not the plastic surgeon can 'rebuild' that area. With lumpectomy, there would be radiation. Chemo to be determined. Nurse-Navigator has called me. I feel like we have a team and ready to get this done. Thank you for this site and all the information and support.

Hi BB101, I had once read that ADH/ALH increases a patient's odds of breast cancer by 500% as compared to the average woman/man without ADH/ALF, although I do not recall the source. The "what if's" are definitely frightening. I also had both a lumpectomy followed by a bilateral mastectomy. The multiple Mixed MC lesions had only been discovered from my BMX, as prior lumpectomy and prior imaging had not shown any of the several Mucinous cancers, only the other subtypes I had earlier (Invasive Solid Papillary & DCIS).

I will always be eternally grateful to VR & BC.org and to all of you for having posted & commented on the M.D.Anderson 2009 study linked earlier. One never knows if we'll be part of that 38% with multiple "invisible" MC lesions. And a warm welcome to the new MC patients who will help to guide all of us. Best wishes to all.

Obsolete,

So frightening! The mucinous cancer wasn't even detectable by imaging? Oh, man you dodged a very big bullet! It's the "what if's" that shakes me to my core. I was literally being pushed to have a lumpectomy followed by radiation therapy. I begged the breast surgeon for a bilateral mastectomy and she said, "NO!" Of course I wanted the cancer out ASAP so I agreed to the lumpectomy but in the meantime I was making plans to see another breast surgeon. Can you imagine if both had said, "No, we're only going to do a lumpectomy followed by radiation therapy." Could the radiation have caused the atypical cells to mutate to cancer? This could have been a never ending nightmare until my death.

Linny,

Sending good vibes your way for your surgery on Sept. 25. Please let us know how things go. You'll breathe a huge sigh of relief once the cancer beast is out.
