What is the difference between ductal carcinoma and lobular carcinoma?

There are two main types of breast cancer: „„Ductal carcinoma starts in the tubes (ducts) that move milk from the breast to the nipple. Most breast cancers are of this type. „„Lobular carcinoma starts in the parts of the breast, called lobules, which produce milk.

Is ILC worse than IDC?

In the subgroup analysis stratified by negative hormone receptor and positive lymph node status, we found that the prognosis of ILC was significantly worse compared to IDC.

What is ILC breast cancer?

Invasive Lobular Carcinoma (ILC), also known as infiltrating lobular carcinoma, is the second most common form of breast cancer diagnosed in the United States, representing 10-15 percent of diagnosed invasive breast cancers.

What is the difference between invasive and infiltrating ductal carcinoma?

Invasive ductal carcinoma (IDC), also known as infiltrating ductal carcinoma, is cancer that began growing in a milk duct and has invaded the fibrous or fatty tissue of the breast outside of the duct. IDC is the most common form of breast cancer, representing 80 percent of all breast cancer diagnoses.

Is invasive lobular carcinoma the same as invasive ductal carcinoma?

Invasive Lobular Carcinoma (ILC) (About 80\% are invasive ductal carcinomas.) Invasive means that the cancer has “invaded” or spread to the surrounding breast tissues. Lobular means that the cancer began in the milk-producing lobules, which empty out into the ducts that carry milk to the nipple.

Is ILC That same as Lcis?

It’s different from lobular carcinoma in situ (LCIS). That’s another type of abnormal cell growth in the breast that stays inside the lobules. ILC is more likely to be found in both breasts than other types of breast cancer. It can also spread to other areas of your body.

Where does IDC spread to?

IDC starts in the cells that line a milk duct in the breast. From there, the cancer breaks through the wall of the duct, and grows into the nearby breast tissues. At this point, it may be able to spread (metastasize) to other parts of the body through the lymph system and bloodstream.

Is invasive lobular carcinoma slow growing?

Invasive lobular carcinoma is known for being a slow growing tumor, usually grade I or II. Slow growing, grade I tumors don’t usually respond well to chemotherapy, so hormonal therapy is key for this type of cancer.

What is lobular carcinoma in situ?

Lobular carcinoma in situ (LCIS) is a type of breast change that is sometimes seen when a breast biopsy is done. In LCIS, cells that look like cancer cells are growing in the lining of the milk-producing glands of the breast (called the lobules), but they don’t invade through the wall of the lobules.

How long does it take for invasive ductal carcinoma to spread?

According to the Robert W. Franz Cancer Research Center at Providence Portland Medical Center, breast cancer cells need to divide at least 30 times before they are detectable by physical exam. Each division takes about 1 to 2 months, so a detectable tumor has likely been growing in the body for 2 to 5 years.

Does ILC respond to chemo?

However, the overall consensus is that ILC responds poorly to chemotherapy with lower OS rates following NAC than observed in IDC (3, 65).

What stage is LCIS?

Stage 0 breast cancer used to include lobular carcinoma in situ (LCIS). Even though the name contains the word carcinoma, LCIS is no longer categorized as cancer. LCIS involves atypical cells in your lobules, but they don’t spread beyond your lobules.

What is invasive lobular carcinoma (ILC)?

Invasive Lobular Carcinoma (ILC) Lobular means that the cancer began in the milk-producing lobules, which empty out into the ducts that carry milk to the nipple. Carcinoma refers to any cancer that begins in the skin or other tissues that cover internal organs — such as breast tissue. All together, “invasive lobular carcinoma” refers to cancer…

Is invasive lobular breast cancer more difficult to detect than IDC?

Background: Invasive lobular breast cancer (ILC) is less common than invasive ductal breast cancer (IDC), more difficult to detect mammographically, and usually diagnosed at a later stage. Does delayed diagnosis of ILC affect survival?

What is the difference between lobular and invasive ductal carcinoma?

(About 80\% are invasive ductal carcinomas.) Invasive means that the cancer has “invaded” or spread to the surrounding breast tissues. Lobular means that the cancer began in the milk-producing lobules, which empty out into the ducts that carry milk to the nipple.

What does ILC stand for in breast cancer?

Invasive Lobular Carcinoma (ILC) Invasive Lobular Carcinoma (ILC), also known as infiltrating lobular carcinoma, is the second most common form of breast cancer diagnosed in the United States, representing 10-15 percent of diagnosed invasive breast cancers.
