The breast may get bigger, harder, tender, or itchy. This can make it harder to find IBC early. TNBC is invasive breast cancer that certain types of treatment won't work on. It's called triple-negative because the cancer cells are missing three kinds of proteins that breast cancers are tested for: estrogen and progesterone receptors proteins that help cells respond to hormones , and another protein called HER2 a protein that other types of breast cancer make too much of.
When a breast cancer tests negative for all three of these proteins, it means the cancer might be harder to treat. A change seen on your mammogram may be the first sign of breast cancer. Or you may have found a lump or other change in your breast. The doctor will ask you questions about your health and will do a physical exam. A breast exam is done to look for changes in the nipples or the skin of your breasts. The doctor will also check the lymph nodes under your arm and above your collarbone.
Swollen or hard lymph nodes might mean breast cancer has spread there. If signs are pointing to breast cancer , more tests will be done. Here are some of the tests you may need :. Mammogram : This is an x-ray of the breast. Mammograms are mostly used to find breast cancer early. But another mammogram might be done to look more closely at the breast problem you might have. MRIs can be used to learn more about the size of the cancer and look for other tumors in the breast.
Breast ultrasound: For this test, a small wand is moved around on your skin. It gives off sound waves and picks up the echoes as they bounce off tissues.
The echoes are made into a picture that you can see on a computer screen. Ultrasound can help the doctor see if a lump is a fluid-filled cyst which is not likely to be cancer , or if it's a tumor that could be cancer. Nipple discharge exam: If you have fluid coming from your nipple, some of it may be sent to a lab. There, it will be checked to see if there are cancer cells in it. But not all women with breast cancer need these tests.
In a breast biopsy , the doctor takes out small pieces of breast tissue to check them for cancer cells. A biopsy is the only way to tell for sure if you have breast cancer. There are many types of biopsies.
Ask your doctor what kind you will need. Each type has risks and benefits. The choice of which type to use depends on your own case. This is often done in a hospital using local anesthesia numbing medicine.
You might also be given medicine to make you sleepy. If breast cancer is found on your biopsy, the cells will be checked for certain proteins or genes that will help the doctors decide how best to treat it.
You might also need more tests to find out whether the cancer has spread. The breast cancer cells will be tested for certain proteins called estrogen and progesterone receptors. If the cancer has these proteins, it's called a hormone receptor positive breast cancer. The cells are also tested to see if the cancer makes too much of the HER2 protein. If it does, it's called a HER2-positive cancer. An ultrasound can distinguish between a solid mass, which may be cancer, and a fluid-filled cyst, which is usually not cancer.
An MRI uses magnetic fields, not x-rays, to produce detailed images of the body. A special dye called a contrast medium is given before the scan to help create a clear picture of the possible cancer.
A breast MRI may be used after a woman has been diagnosed with cancer to find out how much the disease has grown throughout the breast or to check the other breast for cancer.
Breast MRI is also a screening option, along with mammography, for some women with a very high risk of developing breast cancer and for some women who have a history of breast cancer see Risk Factors and Prevention. MRI may also be used if locally advanced breast cancer is diagnosed or if chemotherapy or endocrine therapy is being given first, followed by a repeated MRI for surgical planning see Types of Treatment.
Finally, MRI may be used as a surveillance method following a breast cancer diagnosis and treatment. A biopsy is the removal of a small amount of tissue for examination under a microscope. Other tests can suggest that cancer is present, but only a biopsy can make a definite diagnosis.
A pathologist then analyzes the sample s. A pathologist is a doctor who specializes in interpreting laboratory tests and evaluating cells, tissues, and organs to diagnose disease. Fine needle aspiration biopsy. This type of biopsy uses a thin needle to remove a small sample of cells. Core needle biopsy. This type of biopsy uses a wider needle to remove a larger sample of tissue. This is usually the preferred biopsy technique for finding out whether an abnormality on a physical examination or an imaging test is invasive cancer and, if so, what the cancer biomarkers are, such as hormone receptor status ER, PR and HER2 status.
They are made by the tumor or by the body in response to the cancer. This information will help develop a treatment plan. Surgical biopsy. This type of biopsy removes the largest amount of tissue.
Because surgery is best done after a cancer diagnosis has been made, a surgical biopsy is usually not the recommended way to diagnose breast cancer.
Most often, non-surgical core needle biopsies are recommended to diagnose breast cancer in order to limit the amount of tissue removed. Since many people who are recommended to undergo breast biopsy are not diagnosed with cancer, using a needle biopsy for diagnosis reduces the number of people who have surgery unnecessarily. Image-guided biopsy. During this procedure, a needle is guided to the location of the mass or calcifications with the help of an imaging technique, such as mammography, ultrasound, or MRI.
A stereotactic biopsy is a type of image-guided biopsy that is done using mammography to help guide the needle. Your doctor will let you know what type of biopsy is best for your situation.
A small metal clip is usually put into the breast at the time of biopsy to mark where the biopsy sample was taken, in case the tissue is cancerous and more surgery is needed. This clip is usually titanium so it will not cause problems with future imaging tests, but check with your doctor before you have any imaging tests done. Sentinel lymph node biopsy. In breast cancer, these are usually the lymph nodes under the arms called the axillary lymph nodes. The sentinel lymph node biopsy procedure is a way to find out if there is cancer in the lymph nodes near the breast.
Learn more about sentinel lymph node biopsy in the Types of Treatment section. Analyzing the sample s removed during the biopsy can help your doctor learn about specific features of a cancer that help determine your treatment options.
Tumor features. Examination of the tumor under the microscope is used to determine if it is invasive or non-invasive in situ ; ductal, lobular, or another type of breast cancer; and whether the cancer has spread to the lymph nodes. The margins or edges of the tumor are also examined, and the distance from the tumor to the edge of the tissue that was removed is measured, which is called margin width.

No alternative medicine treatments have been found to cure breast cancer.
But complementary and alternative medicine therapies may help you cope with side effects of treatment when combined with your doctor's care.
