I am so glad your DIS friend pointed you in our direction, DeeCeeSW, although I am sorry you have joined our ranks.
The radiologist who did my stereotactic needle biopsy told me nothing. I received a call the next day from my surgeon, telling me it was cancer but very treatable, and I was scheduled to go in and see him within a couple of days to discuss a treatment plan more fully.
Basically, we went over in detail the path report, the surgeon explaining it all. My situation was similar, although I was a decade older than you. Like you it all started when I had a screening mammogram which showed calcifications, was called back for a diagnostic diagram and was advised to contact my OBGYN. He sent me to my surgeon, who ordered the stereotactic biopsy.
The biopsy showed like you I also had widespread DCIS, in more than one quadrant of the breast, my surgeon described it as multifocal. The standard of care was and I think still is for a mastectomy with multifocal cancer although I know there have been at least limited studies with doing lumpectomies plus radiation for multifocal. It would be very difficult to get a good cosmetic result though in the case of a woman with smallish breasts, let alone the issue of removing all the DCIS. DCIS tends to snake around throughout the breast.
I also had one very small area of invasive cancer. With invasive cancer, you will commonly have at least a sentinel lymph node removed, perhaps more due to the nature of multifocal areas. That was done for me when the mastectomy was done. Before that surgery they scheduled me for a CT scan of the abdomen and chest, chest xrays, and a bone scan. All fun tests, however, nothing showed up, my lymph nodes (my doc did a full axillary dissection. . . all 16 he removed came up clear), and the path report done after the mastectomy showed more DCIS but no more invasive cancer.
All good there.
When do you see the surgeon again?
I suggest you bring your husband or a close family member or friend with you as moral support for that next visit. Ask to see and even get a copy of your biopsy path report. I also recommend women to start up a file with ALL their test results and carry that with them to visits.
I understand your concern about your son. Even though I am a lot older than you, our youngest was only 8 when I was diagnosed. The timing stunk too, I was scheduled for the biopsy the day after her first communion. It was hard to enjoy the moment that day.
I too was told 80% of the time calcifications are benign, apparently they are very common.
If it is any consolation, DCIS is sometimes called precancer. It is also referred to as the kind of cancer you want if you have to come down with cancer. By its nature it doesn't spread except within the ducts. I have also read that many women have DCIS in their later years, as evidenced by the number of women who die from other causes and are found to have DCIS via an autopsy.
Grim info, but it also tells you that DCIS is very treatable. The invasive component is more worrisome, but there again, there are degrees. Your path report will show the exact size of the invasive component. They measure them in centimeters. Mine was only .1 centimeter, quite small. The path report may also show the grade of the tumor, another important consideration in the treatment plan.
Tests can also be run to see if you will respond to hormone therapy. The path report from my mastectomy showed my tumor did respond to hormones, so I am on Tamoxifen for five years, my only treatment aside from the surgery itself.
There is an excellent website called breastcancer.org where you can read up a good bit on both DCIS and multifocal. I am an information gatherer so I tried to learn all I could before going back to the surgeon. That way I was prepared to ask a lot of questions. I really drilled that poor guy, and went on and did the same thing with a second surgeon because I wanted a second opinion. Each woman has her own approach here, that one may or may not work for you.
Please post again and let us know how you are doing as you go forward on this journey. We consider ourselves to be survivors from the day of diagnosis, that is when the fight begins. We'll be here to walk that road with you.
As Merry posted above, please feel free to ask any question either here, or by pm. She is absolutely right that each case is different, each woman is different.
I had reconstruction surgery about a year and a half ago, with a reduction and am very pleased. At the time of diagnosis my doc recommended waiting on the reconstruction, and I believe looking back it was the right course for me. Although immediate reconstruction is an option in lots of cases,for me the reconstruction, although it was physically challanging, took on a very positive, healing aspect. It seemed to put me back together again both physically and emotionally.
