Does hormonal therapy help with DCIS?
In women diagnosed with DCIS, hormonal therapy can help prevent DCIS from recurring. If a woman doesn’t undergo radiation therapy, hormonal therapy can reduce her chances of invasive cancer in the opposite breast, but not invasive cancer in the same breast. And, hormonal therapy used in addition to radiation treatment apparently has no benefit, ...
Does tamoxifen reduce the chances of breast cancer?
For women who did not have radiation therapy, tamoxifen reduced the chances of developing DCIS within 10 years in the same breast by about 3% and the chances of developing DCIS in the other breast by about 1%. Interestingly, tamoxifen did not significantly decrease the chances of developing invasive breast cancer in the same breast, ...
Does tamoxifen stop breast cancer?
Tamoxifen blocks the effects of estrogen on breast cells, which can stop the growth of cancer cells that are sensitive to estrogen. A study of more than 1,800 pre-menopausal and post-menopausal women with DCIS evaluated the benefits of tamoxifen for women who had lumpectomy and radiation treatment.

HRT after DCIS
Hi guys, I had DCIS and a mastectomy three years ago and since the start of this year I've been experiencing perimenopausal symptoms. My understanding was that my history meant I couldn't take HRT but I've been hearing conflicting advice recently. Does anyone have any experience or knowledge on the subject?
HRT after DCIS
I am sorry to hear about your dilemma in deciding whether to take HRT after having had DCIS.
What is a DCIS?

DCIS is considered non-invasive or pre-invasive breast cancer. DCIS can’t spread outside the breast, but it still needs to be treated because it can sometimes go on to become invasive breast cancer (which can spread).
Can you get BCS without radiation?
BCS without radiation therapy is not a standard treatment, but it might be an option for certain women who had small areas of low-grade DCIS that were removed with large enough cancer-free surgical margins.
Can you do SLNB after mastectomy?
This is because if an area of invasive cancer is found in the tissue removed during a mastectomy, the doctor won’t be able to go back and do the SLNB later, and so may have to do a full axillary lymph node dissection (ALND).
Can a BCS remove DCIS?
Simple mastectomy (removal of the entire breast) may be needed if the area of DCIS is very large, if the breast has several separate areas of DCIS, or if BCS cannot remove the DCIS completely (that is, the BCS specimen and re-excision specimens still have cancer cells in or near the surgical margins).

Is aromatase used for breast cancer?
It is given once monthly as an injection. Currently, it is indicated for use only in hormone-sensitive metastatic breast cancer. The identification of aromatase as an essential enzyme in the peripheral conversion of testosterone to estradiol led to the development of further options for hormone suppression.
Is Oxybutynin good for hot flashes?

Is ductal carcinoma in situ invasive?
Although ductal carcinoma in situ (DCIS) is a non-invasive form of breast cancer, it can become invasive. Because little is known about which cases will progress, DCIS is treated in much the same way as other forms of breast cancer.
Does radiation treatment for breast cancer reduce recurrence?
The new study shows that treatment including removal of the cancer followed by radiotherapy to the affected breast leads to very low rates of recurrence.

The Case
A 46-year-old woman had a routine screening mammogram that showed new calcifications in the posterior left breast. A diagnostic mammogram showed several small punctate calcifications, and a 6-month interval follow-up was recommended. The follow-up mammogram showed pleomorphic calcifications spanning 1.5 cm (Figure 1).
Discussion
DCIS (or stage 0 breast cancer) accounts for approximately 20% of mammographically detected breast cancers. [1] Although DCIS has become a rather common diagnosis, the biology of the disease is not well understood.
Outcome of This Case
Chemotherapy is ongoing, and the patient is tolerating treatment well. The next step will be surgical excision and, potentially, axillary lymph node dissection. Axillary radiation will be given regardless. If there is concern about the morbidity associated with axillary dissection, this will be addressed in a multidisciplinary discussion.

Research we're watching
A new study published online August 10 by the Journal of the American Medical Association shows that women with ductal carcinoma in situ (DCIS) — cancerous changes to the cells inside the milk ducts of the breast — may have better results if they have radiation in addition to a lumpectomy.
