What is the treatment for carcinoma in situ?

TREATMENT APPROACH Patients with DCIS undergo local treatment with breast-conserving therapy (BCT) or mastectomy. BCT consists of lumpectomy (also called breast-conserving surgery, wide excision, or partial mastectomy) followed in most cases by adjuvant radiation.

What is the difference between in situ and invasive cancer?

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.

Which stage of cancer is called in situ?

A common question is, “What stage of cancer is carcinoma in situ?” Carcinoma in situ is referred to as stage 0 cancer. At this stage, cancer is considered non-invasive. Stage 1 cancers and beyond are considered invasive, meaning that even if low, there is a potential they could spread.

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.

What does carcinoma in situ of breast mean?

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.
