What Different Types Of Breast Cancer Are There – Clinical Medicine by Elizabeth Berger, MD, MS – Written by Nancy Moyer, MD. – Updated on April 24, 2024
Breast cancer can be classified in many ways. It is mostly classified by where it comes from and whether it moves from there.
What Different Types Of Breast Cancer Are There
, about 1 in 8 American women will develop breast cancer at some point. It is less common in men, with about 1 in 800 men developing it in their lifetime.
What Are The Different Types Of Breast Cancer: Common, Rare, Treatment
Your breast has lobes and ducts that are surrounded by fat and connective tissue. The lobules of the gland produce milk, which is transferred to the breast through ducts.
Breast cancer occurs when normal cells in the lobules, ducts, or other breast tissue are damaged and grow out of control. Abnormal cells grow rapidly and accumulate to form a tumor.
If a tumor grows but has not spread to nearby breast tissue, it is called a breast tumor and is not considered cancer. A malignant tumor spreads by invading surrounding tissues and is considered cancerous.
Because it can start in the lobules, ducts, or other tissues, there are different types of breast cancer.
Breast Cancer: Symptoms, Types, Causes, And Treatment
Another important characteristic of breast cancer is whether it has invaded the surrounding tissue or stayed where it originated.
Non-malignant lesions may develop in ductal or lobular cysts but will not spread from their original location. Therefore, doctors can consider these injuries as “in situ,” which means “in the original.”
There are two types of cancer: ductal carcinoma in situ (DCIS) and lobular carcinoma in situ (LCIS).
Breast cancer develops in the ductal or lobular cells, but does not stop at the source. Instead, it spreads and invades the surrounding areas. Another name for this is “seepage”.
Understanding Breast Cancer Types
There are two main types of breast cancer: invasive (infiltrating) ductal carcinoma (IDC) and invasive (infiltrating) lobular carcinoma (ILC).
DCIS is found in the cells lining the milk ducts. It stays there and does not spread to nearby tissues.
Doctors consider it precancerous, or preinvasive, because if left untreated, it can become invasive and spread to nearby tissues. Some cases of DCIS do not progress to cancer even without treatment. DCIS accounts for approx
DCIS is often curable. It is usually treated with a lumpectomy followed by radiation therapy or a mastectomy.
Invasive Carcinoma Of No Special Type
If the cancer is a positive hormone receptor, it can be treated with tamoxifen or an aromatase inhibitor (for people who have passed) for 5 years after surgery. This treatment is expected to reduce the risk of recurrence of DCIS or breast cancer.
LCIS is a type of growth of cells in the lobules (milk glands) of the breast. LCIS is not cancer, although it can be
LCIS treatment requires close follow-up with your doctor because of the high risk of breast cancer.
ILCs are formed in the cells lining the lobule and spread to adjacent tissues. It is the second most common type of breast cancer, accounting for approx
How Breast Cancer Affects The Body
ILC is more often a slow-growing tumor and may not respond to chemotherapy. However, this is not always the case.
When breast cancer tissue is removed from your body, it is tested for these proteins. Cancer cells are then classified according to the presence or absence of proteins on their surface.

This type has estrogen receptors (ER), progesterone receptors (PR), or both. ER-positive tumors have estrogen receptors, while PR-positive tumors have progesterone receptors. This species often needs the same hormones and receptors to grow.
This type has extra copies of the HER2 gene, causing it to produce more growth hormone called human growth factor receptor 2 (HER2). This hormone allows the cancer to grow faster.
Breast Cancer Staging: What You Need To Know
Cancers that do not have ER, PR or HER2 receptors are called triple negative. This is more common in people with a BRCA1 mutation, so your doctor may recommend testing for this mutation if the cancer is triple.
Many types of breast cancer are often named by how they look under the microscope. Here’s a closer look at the rare species.
Of all breast cancer. It is a fast-growing, type of breast cancer that has different symptoms than most types of breast cancer, such as breast swelling and thickening of the skin.
Blockage of the lymphatic system in the chest causes symptoms of IBC. These symptoms develop quickly, usually within 3 to 6 months.
Male Breast Cancer: Symptoms, Signs & Treatment
Paget’s disease is a rare cancer that forms in the milk ducts and spreads to the skin around the nipples and nipples. This type of breast cancer is usually accompanied by DCIS or breast cancer.
A fibroepithelial lesion is a collection of different tissue growths in the breast. This group of lesions includes tumors and cancer. Because of the possibility of detecting tumors, doctors often recommend removing them if they are found.
One such fibroepithelial lesion is a phyllodes tumor. This is a very rare type of damage
In rare cases, phyllodes tumors are not cancerous, so they usually do not spread beyond the breast. But they can grow quickly, and some can be considered borderline, meaning they have characteristics that can make them cancerous at a later stage.
What Are The Most Common Types Of Breast Cancer?
Tubular carcinoma is a subtype of ductal carcinoma (IDC). This type of breast cancer gets its name from the tube-like structures that make up the tumor, which can be seen under a microscope.
Mucinous carcinoma, also known as colloid carcinoma, is a rare form of IDC. About 2% of breast cancers are “pure” mucinous carcinomas, while up to 7% of breast cancers contain some portion of mucinous carcinoma cells.
In this type of cancer, the cancer is made up of small cells that appear to be floating in the dust.
Breast cancer is usually a soft, lumpy, lumpy lump in the breast. Masses tend to develop in the center of the breast and are more common in people with BRCA1 mutations.
Basic Types Of Breast Cancer
Symptoms of breast cancer can vary greatly. Some types of breast cancer may have no symptoms.
Sometimes the lump may be too small to feel or cause changes in the breast or surrounding area. In such cases, cancer cells are first detected by screening methods such as mammography.
It is important to know how your breasts usually look and feel. This will help you notice the changes.
There are many types of breast cancer. Some types develop in the lobules that produce breast milk, while others develop in the cells that cover the milk ducts. Some tumors are benign and harmless, but others can be malignant, invading nearby breast tissue.

Regular breast cancer screening and mammography help detect breast cancer in its early stages. Getting regular breast cancer screenings gives you the best chance of staying healthy and cancer-free for many years.
According to the American Cancer Society, on average, breast cancer is treated before it spreads

In a disease known as breast cancer, the abnormal cells in the breast begin to grow without stopping. After a breast cancer diagnosis, your doctor will review the results of any imaging tests and your pathology report to better understand your tumor’s characteristics.
Are There Different Types Of Breast Cancer?
Your healthcare team will diagnose the type of breast cancer by analyzing a tissue sample taken during a breast exam. Your doctor will use this information to determine which of the many treatment options is best for you.
Some breast cancers are particularly sensitive to estrogen and progesterone, both female hormones in the body. Breast cancer cells contain receptors on the outside of their cell walls that allow them to take in certain genes circulating in the body.
Your doctor will better understand how to treat the cancer or stop it from coming back if you let them know if your breast cancer is sensitive.
Ki67 is a nuclear antigen that is a good marker of cell proliferation in culture and tumorigenesis. It has been proposed as a useful clinical marker for breast cancer classification, prognosis and predicting response to treatment. The Ki67 test is performed in tumor cells with receptors.
Breast Cancer In Nz
Experts are increasingly classifying breast tumors based on genetic information. Based on the results of the immunohistochemistry test, breast cancer is divided into four categories:
Let’s say your doctor knows more about your chemical and genetic makeup. In this case, they can choose the most suitable treatment for the particular type of cancer.
