Breast Cancer
Cancer results when the cells in the body get divides and multiply in an uncontrolled way. This is because of the mutations of the genes which regulate cell growth.
In breast cancer, breast cells get affected. The cancer is either in the lobules or the ducts of the breast. Lobules are the glands in the female body that produces milk, while ducts are the passage that brings the milk from lobules to the nipple. Fatty or fibrous connective tissues within the breast can also cause cancer. Abnormal and uncontrolled growth of breast cells leads to breast cancer.Learn more about Breast cancer

Risk Factors of Breast Cancer
According to the Centers for Disease Control, most cancers are diagnosed in women over 55. As the percentage of older Americans continues to rise, we can expect an increase in the number of newly diagnosed cases of breast cancer.
Learn more about how different factors appear to slightly increase your risk for developing breast cancer.
- Age
- Personal history of breast cancer
- Family history of breast cancer
- BRCA and PALB2 gene mutations
- Early menstruation or late menopause
- Age at first pregnancy
- Benign breast disease
- Hormone replacement therapy
- Oral birth control

- Radiation exposure
- Women in their 30s have a one in 227 (0.44 percent) chance of developing breast cancer, according to the National Cancer Institute.
- In comparison, the risk for women in their 60s is one in 28 (3.6 percent).
- The lifetime breast cancer risk for women by the time they reach their 90s is about one in eight (12.4 percent).
- several members of your family in multiple generations have had breast cancer or other forms of cancer — ovarian cancer or male breast cancer in particular
- your breast cancer occurred at a fairly young age (under age 50)
- your breast cancer occurred in both breasts
- your breast cancer is triple-negative, meaning it lacks the estrogen receptor, progesterone receptor, and HER2 receptor
Types of Breast Cancer
Breast cancer types are determined by the way a sample of cells from the tumor, collected during a breast biopsy or breast cancer surgery, looks under a microscope. Breast cancers are also classified according to how sensitive they are to the hormones estrogen and progesterone, their levels of certain proteins that play a role in breast cancer growth (such as HER2), their genetic makeup, and other characteristics. This classification helps doctors predict how a cancer will respond to specific treatments, and it also allows them to personalize treatment.
Use this guide to learn about a variety of types of breast cancer and how they are classified.
- invasive breast cancer versus noninvasive breast cancer
- ductal carcinoma in situ
- invasive ductal carcinoma
- invasive lobular carcinoma
- lobular carcinoma in situ and atypical lobular hyperplasia
- inflammatory breast cancer
- breast sarcoma
- metaplastic carcinoma
- estrogen receptor-positive breast cancer and progesterone receptor-positive breast cancer
- HER2-positive breast cancer
Breast Cancer Diagnosis
If a physical exam, a mammogram, or other imaging tests show a suspicious change in one of your breasts, the next step is likely to be a biopsy. During a breast biopsy, a tissue sample is taken from your breast. It’s then examined under a microscope by a pathologist — a doctor who specializes in diagnosing disease — who can determine whether it contains cancerous cells.
Breast biopsies are performed in different ways based on your situation.
Fine-Needle Aspiration (FNA)
During an FNA procedure, a doctor inserts a very thin needle into the area of the breast with suspicious changes and removes a few cells. FNA is relatively quick, and any discomfort lasts only a few seconds. A pathologist examines the fluids or cells under a microscope to determine if they are benign (normal) or malignant (cancerous).
FNA is rarely used as the primary way to diagnose breast cancer because it doesn’t allow us to reliably tell the difference between in situ cancers and invasive ones. We often use FNA to evaluate whether breast cancer has spread to the axillary lymph nodes (located in the armpits) or other organs. In such cases, we can also test the expression of breast cancer tumor markers such as ER, PR, and HER2 in the tumor cells present in an FNA sample provided that enough cells are available.
Core Needle Biopsy
We use a core needle biopsy if we need a tissue sample that’s larger than what an FNA can get. We also use it if the tissue removed during an FNA doesn’t lead to a definitive diagnosis. Core needle biopsy requires the use of a local anesthetic to numb the area and a larger, hollow needle to remove a thin cylinder of tissue.
Core needle biopsy is the preferred method for sampling suspicious breast lesions. We routinely assess the expression of ER, PR, and HER2 in invasive carcinoma using core needle biopsy samples. The information obtained from a core needle biopsy informs the treatment plan your doctor recommends
Image-Guided Biopsy
Image-guided procedures use computer-imaging techniques to guide a needle into the breast to collect cells or tissue from a suspicious area. We use this method to diagnose suspicious areas that can be seen on a mammogram, ultrasound, or MRI but are too small to be felt by touch. Our breast imaging specialists have developed and shown the benefits of this approach. For most women, this type of breast biopsy can spare them a more uncomfortable and expensive surgical biopsy. It may also enable doctors to make a diagnosis more quickly so that women may start their treatment sooner.
A radiologist — a doctor whose specialty is using imaging tests to diagnose disease — performs this type of biopsy. He or she can pinpoint the exact location of the abnormal cells or tissue using x-ray, ultrasound, MRI, or other imaging techniques. Which technique is used depends on what the cells or tissue look like and what would create the best image of them.
Surgical Biopsy
A surgical biopsy is a brief procedure that takes place in an operating room but does not require you to stay in the hospital overnight. It does require you to be lightly sedated. The surgeon makes a small incision and removes either the entire mass of suspicious breast tissue or a representative sample, depending on its size and location.
We may recommend a surgical biopsy for two main reasons. The first is if other breast biopsy procedures don’t provide a clear diagnosis. The second is if the area containing possible cancer cells is too deep or too shallow for a fine needle aspiration or a core biopsy.
Breast Cancer Stages
At some point, your doctor will tell you what stage your cancer is. Put simply, the stage describes how widespread or advanced the cancer is in the breast tissue and possibly other parts of your body. Determining the stage helps doctors explain the breadth of the cancer to you. It also helps them determine how to move forward with treatment, including surgery, if needed.
Breast cancer is also classified according to other characteristics. These include how sensitive it is to the hormones estrogen and progesterone as well as to the level of certain proteins that play a role in breast cancer growth, such as HER2. It is also classified by the cancer’s genetic makeup.
- stage 0 breast cancer
- stage I breast cancer
- In stage IA, a tumor measures up to 20 millimeters (about the size of a grape), and there’s no cancer in the lymph nodes.
- Stage IB can be described as either:
- a small tumor in the breast that is less than 20 millimeters plus small clusters of cancer cells in the lymph nodes; or
- no tumor in the breast plus small clusters of cancer cells in the lymph nodes.
- stage II breast cancer
- Either there is no tumor in the breast or there is a breast tumor up to 20 millimeters (about the size of a grape), plus cancer has spread to the lymph nodes under the arm.
- A tumor of 20 to 50 millimeters is present in the breast, but cancer has not spread to the lymph nodes.
- A tumor of 20 to 50 millimeters is present in the breast, along with cancer that has spread to between one and three nearby lymph nodes.
- A tumor in the breast is larger than 50 millimeters, but cancer has not spread to any lymph nodes
- stage III breast cancer
- With or without a tumor in the breast, cancer is found in four to nine nearby lymph nodes.
- A breast tumor is larger than 50 millimeters, and the cancer has spread to between one and three nearby lymph nodes.
- Cancer may also have spread to the skin, causing swelling or inflammation.
- It may have broken through the skin, causing an ulcerated area or wound.
- It may have spread to as many as nine underarm (axillary) lymph nodes or to nodes near the breastbone.
- ten or more underarm (axillary) lymph nodes
- lymph nodes near the collarbone
- some underarm lymph nodes and lymph nodes near the breastbone
- the skin
- stage IV breast cancer
Stage IV is the most advanced stage of breast cancer. It has spread to nearby lymph nodes and to distant parts of the body beyond the breast. This means it possibly involves your organs — such as the lungs, liver, or brain — or your bones.
Breast cancer may be stage IV when it is first diagnosed, or it can be a recurrence of previous breast cancer that has spread.
