What does lobular carcinoma in situ mean?

What stage is lobular carcinoma in situ?

Stage 0 means the cancer cells are still within the breast lobule and have not invaded deeper into the surrounding fatty breast tissue. This is called lobular carcinoma in situ (LCIS), a non-invasive breast cancer. In stage 0 cancer, the cancer has not spread to lymph nodes or distant sites.

Is lobular carcinoma in situ considered cancer?

Lobular carcinoma in situ (LCIS), also known as lobular neoplasia, is a rare condition in which abnormal cells develop in the milk glands, known as lobules, in the breast. These abnormal cells are not considered to be breast cancer and don’t require any treatment beyond surgical removal.

Which is worse LCIS or DCIS?

This is in contrast to LCIS which has risk for the development of invasive breast cancer in either breast over time. In summary, LCIS is considered a risk factor for invasive cancer while DCIS is considered a precursor to invasive cancer.

Is lobular carcinoma in situ invasive?

Women with invasive lobular carcinoma tend to be a few years older than women diagnosed with other types of breast cancer. Lobular carcinoma in situ (LCIS). If you’ve been diagnosed with LCIS — abnormal cells confined within breast lobules — your risk of developing invasive cancer in either breast is increased.

Do you need chemo for invasive lobular carcinoma?

Your treatment options for invasive lobular carcinoma depend on the aggressiveness of your cancer, its stage, your overall health and your preferences. Treatment often consists of surgery and additional (adjuvant) therapy, which may include chemotherapy, radiation and hormone therapy.

Can you survive invasive lobular carcinoma?

Invasive lobular carcinoma survival rates

The average 5-year survival rate for breast cancer is 90 percent, and the 10-year survival rate is 83 percent. This is an average of all stages and grades.

Should I have a mastectomy for LCIS?

Lobular Carcinoma in Situ (LCIS)

Unlike breast cancer, LCIS does not form a tumor. Unlike DCIS, it does not form abnormal cells that can develop into invasive cancer. That is why no surgery is needed to remove LCIS.

Should I worry about LCIS?

How does LCIS affect breast cancer risk? Women with LCIS have about a 7 to 12 times higher risk of developing invasive cancer in either breast. For this reason, women with LCIS should make sure they have regular breast cancer screening tests and follow-up visits with a health care provider for the rest of their lives.

Is lobular breast cancer hereditary?

Definition. Hereditary lobular breast cancer is a rare inherited cancer predisposition associated with pathogenic CDH1 (gene) germline mutations, and without apparent correlation with the hereditary diffuse gastric cancer syndrome.

How often does LCIS become invasive?

Another estimate suggests that an LCIS diagnosis increases breast cancer risk to 21% over the next 15 years. If a woman with LCIS develops an invasive breast cancer, it doesn’t typically happen within a few years. Rather, it is more likely to happen over the long-term — in 10, 15, or 20 years or even beyond that.

Does LCIS form a mass?

Traditionally, LCIS does not present as a mass nor does it contain any microcalcifications on radiological imaging, and the mammography and ultrasound findings do not appear to play a role in prospectively diagnosing LCIS [1-3].
