Your question: What does carcinoma in situ of breast mean?

Is carcinoma in situ really cancer?

In general, carcinoma in situ is the earliest form of cancer, and is considered stage 0. An example of carcinoma in situ is ductal carcinoma in situ, or DCIS, which is considered an early form of breast cancer and occurs when abnormal cells form a breast’s milk duct.

What does in situ breast cancer mean?

A condition in which abnormal cells are found in the tissues of the breast. There are 2 types of breast carcinoma in situ: ductal carcinoma in situ (DCIS) and Paget disease of the nipple. DCIS is a condition in which the abnormal cells are found in the lining of a breast duct.

How is carcinoma in situ treated?

Treatment of DCIS has a high likelihood of success, in most instances removing the tumor and preventing any recurrence. In most people, treatment options for DCIS include: Breast-conserving surgery (lumpectomy) and radiation therapy. Breast-removing surgery (mastectomy)

What is the difference between carcinoma in situ and invasive carcinoma?

In situ breast cancer (ductal carcinoma in situ or DCIS) is a cancer that starts in a milk duct and has not grown into the rest of the breast tissue. The term invasive (or infiltrating) breast cancer is used to describe any type of breast cancer that has spread (invaded) into the surrounding breast tissue.

How fast does ductal carcinoma in situ grow?

It assumes that all breast carcinomas begin as DCIS and take 9 years to go from a single cell to an invasive lesion for the slowest growing lesions, 6 years for intermediate growing DCIS lesions, and 3 years for fast-growing DCIS lesions.

What are the symptoms of carcinoma in situ?

When ductal carcinoma in situ does produce symptoms, the most common include:

  • Breast pain.
  • Bloody discharge from the nipple.
  • A palpable lump in the breast tissue.
  • A red, scaly rash known as Paget’s disease of the breast.

Is carcinoma in situ reversible?

Precancer progresses through dysplastic phases to carcinoma in situ and these changes can be documented by aneuploidy in the abnormal cells. Some of all these degrees of dysplasia, including carcinoma in situ, have been shown to be reversible.

How common is carcinoma in situ cervix?

The mean age at diagnosis is 35–37 years,6,7 and the current incidence rate is approximately 6.6 per 100,000 persons, increasing to 11.2 per 100,000 persons at the peak age of 30–39 years. The average interval between a diagnosis of clinically detectable AIS and early invasive cancer is at least 5 years.

What causes carcinoma in situ?

It’s not clear what causes DCIS. DCIS forms when genetic mutations occur in the DNA of breast duct cells. The genetic mutations cause the cells to appear abnormal, but the cells don’t yet have the ability to break out of the breast duct.

Is severe dysplasia the same as carcinoma in situ?

“severe dysplasia” may be used as synonyms for in situ adenocarcinoma and in situ carcinoma. These are now the preferred terms used by pathologists rather than adenocarcinoma/carcinoma in situ.”

What does in situ mean in medical terms?

(in SY-too) In its original place. For example, in carcinoma in situ, abnormal cells are found only in the place where they first formed.
