Types of Breast Cancer

Breast cancer is a deadly disease that consists of cells in the breast multiplying without apparent control . The type of breast cancer will depend on which cells are cancerous.

It originates in any area of ​​the breast. It is important to know that these are made up of three parts: lobules, ducts and connective tissue. Lobules are glands that produce milk; ducts are tubes that carry milk to the nipple, and connective tissue surrounds parts of the breast.

The cancer usually occurs in the lobules. They are the cells that cover the organs and tissues. They are often a type of carcinoma that arises in cells that produce glands known as glandular tissue.

Types of breast cancer

DCIS cancer: ductal carcinoma in situ

It is considered the most common breast cancer of the non-invasive class. The term “ductal” indicates that cancer originates through the milk ducts. While the term “carcinoma” refers to cancer that occurs in the skin or tissue. The Latin-derived phrase “in situ” means “in its original place.”

This type of cancer is known as “non-invasive”, as it does not exit the milk duct into other normal surrounding breast tissue. Fortunately, this type of cancer is not life-threatening.

CDI Cancer: Invasive Ductal Carcinoma

It turns out to be the most common cancer in this type. Approximately 80% of cases are invasive ductal carcinomas. That is, “invasive” means that the person has been “invaded” in the breast tissues. Regarding “ductal”, it refers to what passed through the ducts.

And as far as the term “carcinoma” is concerned, it points out that it is a type of cancer that originates in the skin or internal organ tissues. Then we have “invasive ductal carcinoma”, which means that the cancer has passed through the milk duct and has invaded the tissues of the breast.

CLI Cancer: Invasive Lobular Carcinoma

It is like invasive ductal carcinoma, one of the most common. About 180,000 women in the United States discover each year that they have invasive breast cancer. And 10% of those cases are invasive lobular carcinomas.

Reviewing each of the terms, we have that invasive refers to the fact that the cancer has “invaded the surrounding breast tissues. Regarding the term “lobular”, he refers that the cancer started in the lobules that produce milk.

And finally, “carcinoma” means that the cancer originates in the skin or other tissues. So we have that, “invasive lobular carcinoma” means that the cancer has broken through the wall of the lobule and invaded the tissues of the breast.

Inflammatory breast cancer

This is a rare but very aggressive type of cancer. According to various statistics, about 5% of all cases in the United States are inflammatory breast cancer.

Among the symptoms we have that it begins with the redness and inflammation of the breast. This one spreads quickly. Your symptoms get complicated in a matter of days. It is very important to know the symptoms and take prompt treatment. Although this cancer is considered serious, there are treatments that control the disease.

Cancer LCIS: lobular carcinoma in situ

It refers to abnormal cell growth in various regions of the breast, which increases the risk of developing invasive breast cancer. Reviewing the terms we have that “lobular” refers to the abnormal cells that begin to grow in the lobules, which are the milk-producing glands found at the ends of the mammary ducts.

When it comes to “carcinoma”, it represents cancer that develops in the skin or tissues that cover internal organs. The term “in situ” refers to “in its original place”, that is, the abnormal growth is within the lobule and does not spread to surrounding tissues.

Cancer Tubular carcinoma of the breast

It is a rare subtype of invasive ductal carcinoma. Statistically it is close to 2% of all cases of breast cancer. Here the tumor is very small and is made up of low-grade tubular cells. That is, they have a similar appearance to normal healthy cells.

Cancer Medullary carcinoma of the breast

It is a rare cancer of invasive ductal carcinoma, which accounts for 5% of all cases of breast cancer. It is called “medullary” because the tumor is a soft mass that resembles a part of the brain known as the medulla or medulla.

Pathologically it appears at any age, normally affecting women in the age range of 45 to 55 years. It more often affects women who have a BRCA1 gene mutation.

Mucinous carcinoma of the breast

It is a rare cancer of invasive ductal carcinoma. It represents 3% of all cases of breast cancer. The tumor forms from abnormal cells made of mucin, one of the main components of the slippery, slimy substance known as mucus.

That “mucus” covers most of the internal surfaces of the human body such as the digestive tract, lungs and liver. In mucinous carcinoma, mucus becomes the main agent of the tumor and surrounds the breast cancer cells.

Cancer Papillary carcinoma of the breast

They are rare and represent 2% of the cases. This type of tumor is diagnosed in older women. It usually has a sharp edge and is made up of small finger-like projections. They often behave very similarly to normal healthy cells, and grade 3 describes rapidly growing, highly abnormal cells.
