DCIS

DCIS or Ductal Carcinoma In Situ is a type of breast cancer that originates in the milk ducts and has not spread to nearby tissue. It is considered the earliest form of breast cancer and is non-invasive.

Overview

DCIS is characterized by the presence of abnormal cells inside a milk duct in the breast. While DCIS is not life-threatening, it does require treatment to prevent the condition from becoming invasive.

Symptoms

In most cases, DCIS has no noticeable symptoms. However, it can sometimes cause signs such as a breast lump or bloody nipple discharge. It is usually detected during a mammogram.

Causes

The exact cause of DCIS is unknown. It is believed to occur when some of the cells lining the milk ducts of the breast start to behave abnormally, multiplying rapidly.

Risk Factors

Factors that can increase the risk of DCIS include age, a family history of breast cancer, high estrogen levels, and previous radiation therapy to the chest area.

Diagnosis

DCIS is most commonly detected during a routine mammogram. If an abnormal area is detected, a biopsy may be performed to confirm the diagnosis.

Treatment

Treatment options for DCIS include surgery (either a lumpectomy or mastectomy), radiation therapy, and hormone therapy. The choice of treatment depends on the size and location of the DCIS, the patient's age and health, and the patient's personal preferences.

Prognosis

The prognosis for DCIS is generally very good. Most women with DCIS are effectively treated and do not develop invasive breast cancer.
