Diagnosed with Grade 3 Pleomorphic Lobular BC

Hello, I am so sorry to hear this. I was diagnosed in June 25 with lobular , had a lumpectomy and just waiting for radiotherapy. I am taking tamoxifen. Today I read a letter on my nhs record that stated it is pleomorphic, no one has ever mentioned this to me before. So like you really concerned and worried xx

Hi may I ask how old you are? I got diagnosed with pleomorphic lobular carcinoma in dec 2024 at age 37

I had mastectomy and reconstruction feb 2025, followed by auxiliary node clearance march 2025, then my implant rejected they tried to save it at my request in July, then further rejection leading to implant removal September 2025. I had 12 paclitaxel. 4 e.c 15 radiotherapy that finished Christmas Eve 2025. I am currently on letrozole, abemaciclib and goserelin. In September/October I will have second mastectomy after that’s healed I will have a hysterectomy. As I also have palb2 gene defect

Stage 2 32mm tumour with 5/33 nodes positive. I can’t seem to get any straight answers from my oncologist and I’m aware how rare plc is but I’m finding it difficult to find anyone my age that’s had/has it. I’m hoping to be able to speak to people on here that may actually know more about pleomorphic because I feel like my doctor doesn’t

Sending strength and love to everyone going through this nightmare and has been through it :heart:

Hi @plc_under_40 - good to hear from you. I’m 54 and was diagnosed last Oct with PLC 37mm, grade 2 but treated as grade 3, tumour with 2 out of 10 lymph nodes positive. Highly ER/PR positive and HER2 negative. Mastectomy and targeted node dissection. Now had 4 EC and on dose 3 of 12 weekly Paclitaxel. Due 15 rounds of radiotherapy followed by letrozole, biophosphates and Ribociclib. No- one told me much either just that it was a sub type of lobular. I did my own research and asked more questions but there is not much info out there. All I know that it is rare and more aggressive than classic lobular. More prolific and more likely to reoccur earlier than classic lobular. Mine is being treated with everything as it is higher risk. Oncologist thought chemo maybe more effective with pleomorphic as it divides faster and usually classic doesn’t respond that well as slower growing. To start I was a mess but feel calmer now. I do think about the higher risk of reoccurrence and the surveillance as lobular is difficult to spot on mammograms and ultrasounds- I’m going to try to push for MRI. How are you doing now? Sx

Hi

I know its long time since you wrote this but I wonder did choice did you make?

Same diagnosis Oncotype 31.

Thank you

Hi @plc_under_40

Im 44, premenopausal, diagnoised with stage 3 grade 2 pleomorphic lobular on Feb 4th 2026. I was never told it is pleomorphic, i read it on a copy of my surgery results!

Had a bi lateral mastectomy, 12cm cancer in left and 4 mm in right. 10 lymph nodes removed during surgery, all 10 positive and a big spread around them, surgeon said no to going back to remove more nodes. Starting 4 AC and 4 Paxitaxel in 3 weeks time. Radio after. Trying to find more ladies who have/had pleomorphic or even lobular who are going through a similar treatment.

How are u doing now?

Hi lovely I don’t understand why they would leave your other nodes I feel that is very risky and if I was you I would want a second opinion

my first biopsy was 2/4 node positive then 3/29 positive total 5/33 so nowhere near as many as yours. My surgeons attitude to the 2/4 was lets get them all gone to keep you safe

I aM doing well on the medications I’m on still waiting surgeries as preventative and unfortunately just got diagnosed with osteoporosis but all things considered I’m good xx

Hi sharync sorry it’s taken me so long to reply my life is chaos. They don’t tell us enough about it because they don’t know themselves which tbh scares me I’ve read every bit of information I can find on it even the few studies that have been done. We just have to hope for the best I think. Hopefully we will be ok

Lots of strength and love sent your way

Forgot to mention they never told me mine was pleomorphic I also found out by reading my paperwork

Hi there - thank you for your reply.

Do You have the names Of Studies I could read? Quite a lot of the few there are are old so my oncologist said they are outdated Now and treatments That we get - mainly hormone and Ribociclib will Be very effective ….

But they are Still still ductal treatments.

Take care and sending :pink_heart:

I don’t know the names off them I’m Sorry I just googled and let changing the wording

Hello, another ILC person here. Not sure about pleomorphic but mine is HER2 positive which I’m gathering in itself is rare and associated with pleomorphic lobular, so I guess it’s possible. My treatment is neo adjuvant chemo (EC then Docetaxel) with HER2 immune therapy, then surgery expected in the summer. I’m about halfway through chemo and found out that early indication is that the cancer is responding to the treatment which is good.

Hi @plc_under_40
Im nervous too about the lymph nodes. But the medical and radiotherapy oncologists I saw this week are both confident the treatments will work on anything left.

Sorry to hear about ur osteoporosis diagnosis. But glad ur doing good in spite of it all.

Just wanted to give you all a little hope I was diagnosed with a grade 3 (but stage 4) pleomorphic lobular carcinoma back in 2024 with bone metastasis. I am still here and my cancer is currently stable and responding well to treatment (ribocibclib,Anastrozole, Zoladex and Denosumab) yes when I started these treatments the side effects were bad but as time has gone on they have become a lot more manageable, I still suffer pain in my legs and my back but I am still able to work full time and live my life.

Stay positive x,

Hi @kentishlass81

Thank you for posting - so good to hear you are well and living a happy life and working.

amongst this nightmare positive stories are so welcome.

Take care Sxx

Another one here with pleomorphic lobular bc grade 3…….rare, yes, but it seems there are quite a few of us!
I had a lumpectomy in January, clear margins and 1/3 nodes involved. Was on Letrozole but now taken off it during chemo. I’ll go back on it once the chemo has finished, but that’s a long time away! Then it’ll be radiotherapy, bisphosphonates and the CDK 4 &6 inhibitors….and Letrozole, of course, which I have no problems with at all.

It’s a difficult one to get our heads round because it’s been studied so little to any effect, mainly because it IS so rare. I think we’re all left in the dark. But it’s great to know that we can share what we DO know with each other on this thread, and give each other some support. My feelings go out to the younger women who have this ā€˜variant’ of ILBC, because it must be so frightening, knowing it’s so aggressive. But it can and is being treated, so hold fast and never give up hoping.

I’m now 72, so a few more years would be nice, but at least I’ve had my good life. I hope for more, but am willing to settle for what I have left.

All the very best to each and every one of you.
