What does multifocal mean in breast cancer?

(mul-tee-FOH-kul brest KAN-ser) Breast cancer in which there is more than one tumor, all of which have arisen from one original tumor.

Can DCIS be multifocal?

Multifocality was a pathologic feature defined as more than one distinct focus of DCIS, with at least 5 mm of intervening healthy tissue confined to a single quadrant of the breast. For cases with multifocal DCIS, the size of the largest focus was recorded.

Is multifocal breast cancer rare?

Anywhere from 6 to 60 percent of breast tumors are multifocal or multicentric, depending on how they’re defined and diagnosed.

Does multifocal breast cancer require chemotherapy?

There are several treatment options available for multifocal breast cancer. These include lumpectomy, mastectomy, radiation therapy, hormonal therapy, and chemotherapy.

Does multifocal breast cancer require mastectomy?

This is the main reason for excluding BCT for MF/MC breast cancer[34]. Moreover, poor cosmetic results, due to large resections, are also evoked. Therefore, many surgeons continue to perform mastectomy in patients with MF/MC breast cancer.

How do you stage multifocal breast cancer?

To stage multifocal breast cancer, your medical team will order several tests to determine how advanced the disease is. These include imaging studies, blood tests, and a biopsy. For multifocal breast cancer, the medical team focuses on the size and growth of the primary tumor.

Is lobular carcinoma in situ malignant?

These are benign (non-cancerous) conditions, but they both increase your risk of breast cancer. The different types of LCIS are: Classic LCIS: The cells lining the lobules of the breast are smaller and are about the same size.

What is the best treatment for ductal carcinoma in situ?

Radiation therapy 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 lobular carcinoma in situ?

Lobular carcinoma in situ (LCIS) is an uncommon condition in which abnormal cells form in the milk glands (lobules) in the breast. LCIS isn’t cancer. But being diagnosed with LCIS indicates that you have an increased risk of developing breast cancer.

How serious is lobular carcinoma?

The five-year survival rate for invasive lobular carcinoma is high compared to other types of cancer — nearly 100% when treated early. If the cancer has spread to nearby tissues, the five-year survival rate is about 93%. If it has metastasized to other areas of your body, the five-year survival rate is 22%.

What is the survival rate for ductal carcinoma in situ?

Although DCIS doesn’t pose any risk, it can turn invasive and spread to other tissues at any time. The five-year survival rate of ductal carcinoma in situ (DCIS), also known as stage 0 breast cancer, is over 98 percent.
