invasive lobular carcinoma and invasive lobular in situ

Posted by gailmarienewton @gailmarienewton, Jan 17 7:33am

I have recently been diagnosed with invasive lobular carcinoma. I am overwhelmed with info on web. I am interested in treatments. What treatments have you had? How did it affect you? (I also have leukemia....so I am really concerned.)

Interested in more discussions like this? Go to the Breast Cancer Support Group.

Ideas I did not know

@gailmarienewton Good luck with all treatments and after exploring all options trust your gut; you know best what your body can do and what treatments you feel comfortable with.

Maybe start a new question/conversation with a subject like "leukemia and ILC advice"? One of the Mayo mentors will probably read this soon and may suggest the same, or refer you to past thread on leukemia and ILC - or post links to information for your dual diagnosis. Keep smiling and know we are here to support you. Have a great day!

I would highly recommend seeking treatment at a top ranked cancer center who treat comorbidities all the time if, in fact, you are not already a patient at such a center.
You are trying to decide your best course of action...what is your oncology hematologist advising you?

Hello @gailmarienewton,

I combined your new discussion on invasive lobular carcinoma with your existing discussion titled:

"invasive lobular carcinoma"
- https://connect.mayoclinic.org/discussion/invasive-lobular-carcinoma-2/

Here, members who had a chance to share their experiences with you before can see you new post inquiring about best courses of action and things to consider when talking with your care team.

OH - I had Atypical Dutal Hypertrophy (ADH) with a secondary diagnosis (path from lumpectomy of ADH) of Lobular Carcinoma In-Situ (LCIS) in right breast. Having LCIS increases everyones risk of BC in the other breast. I had genetic testing and my lifetime BC score was 35% (that's like 3.5 times higher than the average woman) and since LCIS can evolve into the invasive/metatsatic form, and it is sneaky - hard to detect due to its linear form versus spherical, I had a prophylactic DMX. Path was clear on both breasts and I did not require radio or chem - or axillary dissection. Some cases of LCIS never become invasive - but I had several aunts, cousins on my maternal side who died with BC and had two non-BRCA mutations that are suspect for BC. While DMX might seem extreme to some people my new lifetime risk score is 2-3%.

I will probably not have anymore BC related surgeries; I do worry a little since the lobular form is difficult to visualize and while mine was "In-Situ" I question whether we really know if some of the cells might not have snuck out. I don't focus on that because I am told that chance is really low.

I am happy with my choice of DMX. I chose to remain flat (called an aesthetic flat closure) - once again to avoid further surgeries from rejection or rupture of implants. Please be aware that there is standard replacement of implants due to capsulation, calcification, and contracture around the tissue of the implant (natural process of any embedded device) that happens years out from the initial implant. From other threads (Mayo or other?) I have learned that this is not typically discussed when first offered implants - or sometimes after until a woman complains of hardness, pain, etc. With Best Wishes for clarity in making your decisions and a good prognosis.

@anatomary I just want to speak to the point raised above regarding implants. I found out after I had my implants put in that way you’re taking AI medication’s to suppress estrogen. You are in a greater risk for encapsulation of your implant. My original implants we could stop. The surgery was in May. In September fell a flu shot. My right breast blew up when it turned out I had encapsulation and also a Sonoma underneath the right implant. The surgeon removed it and replaced it with another one. Now I have both rest that are a little bit different. I probably will have to have a third surgery to fix the issue. I think if I have another cancellation issue going forward, I will just opt to also go flat. Not worth it. I hope you are able to make your decision with all of this help. I know it’s not an easy time right now, but you’ll get through it and things will be better when you look back. Sending hugs.

Thank you. I think that I will go flat… everything I read is not positive for other choices.

Good Morning,

I was diagnosed with ILC in January 2025. After testing, markings I started chemo for 12 weeks. Then a single mastectomy followed by a corrective surgery to remove dead skin and the expanders. I am choosing to go flat and just use breast forms. I then did 25 rounds of radiation. I am currently on Letrozole and verzensio. I did fairly well with chemo, not a lot of side effects except awful sleep. Surgery recovery was hard but okay. Radiation made me extremely tired but I just listen to my body. The medication has been the worst so far, emotional roller coaster, vomiting, confusion, hot flashes, jitters etc. It is quite the road but I am still here. My advise- prepare. I put everything I needed on a side table (drugs, water, snacks, phone, remote) for surgeries. My kids (adults) were such a resource of support (emotionally and physically). My neighbors did a meal train for me. I just put out a cooler on my front porch and they dropped of food. My partner joined me for most doctor appointments to take notes and be a second set of ears. I loaded up on streaming channels for the year. Not sure if necessary as with chemo brain you don't remember so can watch the same thing over and over (haha).

Just take it one step at a time. My care team is the best and always responsive. Eat protein and hydrate. Prayers that your journey goes smoothly!!

Thank you so much. I will order the book right now. It is so scary. I have spent hours reading on the internet since my diagnosis 2 days ago.

The book comes today. I had full ultrasound of organs and MRI of breast today. Get results in 2 days.

Thank you all so much. I am worried that I will not make the right decisions for me and appreciate any help. I had a biopsy after 2 mammograms and ultrasound. The invasive lobular carcinoma is a Grade 2 and there are some cells outside the core that are LCIS. I am ER+ and PgR+. I am leaning towards a full mastectomy...I do have leukemia, CVID, and anemia. I am very active, eat healthy, and exercise...just very fatigued since August. Wednesday....more tests...MRI and another ultrasound. PET scan coming up....probably not until Saturday because I have cancer treatment on Thursday for leukemia which makes me ill for a couple of days. But...always smiling....just worried.

@gailmarienewton I think having confidence in your oncologist & surgeon makes a huge difference! I traveled a ways to get treated at a great cancer center in Seattle, rather than my local medical center. The cancer center was less convenient but it was infinitely better for me. I followed all their advice. I was stage 1 & had lumpectomy, 5-day radiation & now take half-dose (10 mg) Tamoxifen. No regrets so far! Sending best wishes to you!
