are there different types of dcis?

Yes: Dcis may be classified into different types based upon the pattern of growth when viewed under a microscope. These include comedo, papillary, cribiform, and solid. The comedo form tends to have the highest potential for becoming invasive if left untreated. Dcis may also be classified by how rapidly the cancer cells are dividing; this is referred to as the grade of the cancer.

Cancer of breast: Dcis is ducal carcinoma in situ. This means there is an early cancer inside a breast duct, but it is isolated in the duct. This means that it has specific treatments available, and has a better prognosis.

How is lcis is different from dcis?

Dr. Barry Rosen answered

Risk factor v cancer: Dcis is a pre-cancerous condition that, if left untreated, could turn into a cancer. It is often detected by mammography. Lcis is not pre-cancerous, however, women who are found to have lcis are at an increased risk of developing breast cancer (in either breast). It is usually not detectable by mammography and is often found incidentally at the time of biopsy.

Why does dcis become invasive?

Unknown: If we knew the answer to this question, women with dcis would not all need surgery! about 50% of dcis (ductal carcinoma in situ), if left untreated, will go on to become invasive cancer. Certain genes in the dcis cells get "turned on", making them invasive, but we don't know what makes this switch happen.

Biopsy: A needle biopsy may be performed under local anesthesia in an office setting without much pain. Dcis can only be diagnosed by direct tissue examination.

And if a needle biopsy is negative, a full excisional biopsy (a small surgery) may be needed.

Is radiation treatment necessary or required for dcis?

Dr. Barry Rosen answered

Sometimes.: The primary treatment for dcis is surgical: either a lumpectomy or a mastectomy. Following a lumpectomy, radiation therapy is often recommended, depending on the type of dcis, the size, and the age of the patient.

What are the treatment options for treating dcis?
2 doctor answers • 10 doctors weighed in

Dr. Barry Rosen answered

Surgery +/- RT: First-line therapy for dcis is surgery, which may involve a lumpectomy or a mastectomy, depending upon the growth pattern of the dcis. Following lumpectomy, radiation therapy (rt) is often recommended to lower the risk of cancer recurrence. Furthermore, tamoxifen may be recommended to prevent a second breast cancer from developing.
