Staging

If the biopsy shows that you have breast cancer, your doctor needs to learn the extent (stage) of the disease to help you choose the best treatment. The stage is based on the size of the cancer, whether the cancer has invaded nearby tissues, and whether the cancer has spread to other parts of the body.

Staging may involve blood tests and other tests:

• Bone scan: The doctor injects a small amount of a radioactive substance into a blood vessel. It travels through the bloodstream and collects in the bones. A machine called a scanner detects and measures the radiation. The scanner makes pictures of the bones. The pictures may show cancer that has spread to the bones.

• CT scan: Doctors sometimes use CT scans to look for breast cancer that has spread to the liver or lungs. An x-ray machine linked to a computer takes a series of detailed pictures of your chest or abdomen. You may receive contrast material by injection into a blood vessel in your arm or hand. The contrast material makes abnormal areas easier to see.

• Lymph node biopsy: The stage often is not known until after surgery to remove the tumor in your breast and one or more lymph nodes under your arm. Surgeons use a method called sentinel lymph node biopsy to remove the lymph node most likely to have breast cancer cells. The surgeon injects a blue dye, a radioactive substance, or both near the breast tumor. Or the surgeon may inject a radioactive substance under the nipple. The surgeon then uses a scanner to find the sentinel lymph node containing the radioactive substance or looks for the lymph node stained with dye. The sentinel node is removed and checked for cancer cells. Cancer cells may appear first in the sentinel node before spreading to other lymph nodes and other places in the body.

These tests can show whether the cancer has spread and, if so, to what parts of your body. When breast cancer spreads, cancer cells are often found in lymph nodes under the arm (axillary lymph nodes). Also, breast cancer can spread to almost any other part of the body, such as the bones, liver, lungs, and brain.

When breast cancer spreads from its original place to another part of the body, the new tumor has the same kind of abnormal cells and the same name as the primary (original) tumor. For example, if breast cancer spreads to the bones, the cancer cells in the bones are actually breast cancer cells. The disease is metastatic breast cancer, not bone cancer. For that reason, it is treated as breast cancer, not bone cancer. Doctors call the new tumor "distant" or metastatic disease.

These are the stages of breast cancer:

Stage 0 is sometimes used to describe abnormal cells that are not invasive cancer. For example, Stage 0 is used for ductal carcinoma in situ (DCIS). DCIS is diagnosed when abnormal cells are in the lining of a breast duct, but the abnormal cells have not invaded nearby breast tissue or spread outside the duct. Although many doctors don't consider DCIS to be cancer, DCIS sometimes becomes invasive breast cancer if not treated.

Stage I is an early stage of invasive breast cancer. Cancer cells have invaded breast tissue beyond where the cancer started, but the cells have not spread beyond the breast. The tumor is no more than 2 centimeters (three-quarters of an inch) across. 

Stage II is one of the following:

• The tumor is no more than 2 centimeters (three-quarters of an inch) across. The cancer has spread to the lymph nodes under the arm.

• The tumor is between 2 and 5 centimeters (three-quarters of an inch to 2 inches). The cancer has not spread to the lymph nodes under the arm.

• The tumor is between 2 and 5 centimeters (three-quarters of an inch to 2 inches). The cancer has spread to the lymph nodes under the arm.

• The tumor is larger than 5 centimeters (2 inches). The cancer has not spread to the lymph nodes under the arm.

Stage III is locally advanced cancer. It is divided into Stage IIIA, IIIB, and IIIC.

• Stage IIIA is one of the following:

• The tumor is no more than 5 centimeters (2 inches) across. The cancer has spread to underarm lymph nodes that are attached to each other or to other structures. Or the cancer may have spread to lymph nodes behind the breastbone.

• The tumor is more than 5 centimeters across. The cancer has spread to underarm lymph nodes that are either alone or attached to each other or to other structures. Or the cancer may have spread to lymph nodes behind the breastbone.

• Stage IIIB is a tumor of any size that has grown into the chest wall or the skin of the breast. It may be associated with swelling of the breast or with nodules (lumps) in the breast skin:

• The cancer may have spread to lymph nodes under the arm.

• The cancer may have spread to underarm lymph nodes that are attached to each other or other structures. Or the cancer may have spread to lymph nodes behind the breastbone.

• Inflammatory breast cancer is a rare type of breast cancer. The breast looks red and swollen because cancer cells block the lymph vessels in the skin of the breast. When a doctor diagnoses inflammatory breast cancer, it is at least Stage IIIB, but it could be more advanced.

• Stage IIIC is a tumor of any size. It has spread in one of the following ways:

• The cancer has spread to the lymph nodes behind the breastbone and under the arm.

• The cancer has spread to the lymph nodes above or below the collarbone.

Stage IV is distant metastatic cancer. The cancer has spread to other parts of the body, such as the bones or liver.

Recurrent cancer is cancer that has come back after a period of time when it could not be detected. Even when the cancer seems to be completely destroyed, the disease sometimes returns because undetected cancer cells remained somewhere in your body after treatment. It may return in the breast or chest wall. Or it may return in any other part of the body, such as the bones, liver, lungs, or brain.

Treatment

Women with breast cancer have many treatment options. The treatment that's best for one woman may not be best for another.

The options are surgery, radiation therapy, hormone therapy, chemotherapy, and targeted therapy. You may receive more than one type of treatment. The treatment options are described below.

Surgery and radiation therapy are types of local therapy. They remove or destroy cancer in the breast.

Hormone therapy, chemotherapy, and targeted therapy are types of systemic therapy. The drug enters the bloodstream and destroys or controls cancer throughout the body.

The treatment that's right for you depends mainly on the stage of the cancer, the results of the hormone receptor tests, the result of the HER2/neu test, and your general health.

You may want to talk with your doctor about taking part in a clinical trial, a research study of new treatment methods. Clinical trials are an important option for women at any stage of breast cancer.

Your doctor can describe your treatment choices, the expected results, and the possible side effects. Because cancer therapy often damages healthy cells and tissues, side effects are common. Before treatment starts, ask your health care team about possible side effects, how to prevent or reduce these effects, and how treatment may change your normal activities.

You may want to know how you will look during and after treatment. You and your health care team can work together to develop a treatment plan that meets your medical and personal needs.

Your doctor may refer you to a specialist, or you may ask for a referral. Specialists who treat breast cancer include surgeons, medical oncologists, and radiation oncologists. You also may be referred to a plastic surgeon or reconstructive surgeon. Your health care team may also include an oncology nurse and a registered dietitian.

At any stage of disease, supportive care is available to control pain and other symptoms, to relieve the side effects of treatment, and to ease emotional concerns. Information about such care is available on the NCI Web site at http://www.cancer.gov/cancertopics/coping and from the NCI Cancer Information Service at 1-800-4-CANCER (1-800-422-6237) or at LiveHelp (http://www.cancer.gov/help).

You may want to ask your doctor these questions before you begin treatment: What did the hormone receptor tests show? What did other lab tests show? Would genetic testing be helpful to me or my family? Do any lymph nodes show signs of cancer? What is the stage of the disease? Has the cancer spread? What are my treatment choices? Which do you recommend for me? Why? What are the expected benefits of each kind of treatment? What can I do to prepare for treatment? Will I need to stay in the hospital? If so, for how long? What are the risks and possible side effects of each treatment? How can side effects be managed? What is the treatment likely to cost? Will my insurance cover it? How will treatment affect my normal activities? Would a research study (clinical trial) be appropriate for me? Can you recommend other doctors who could give me a second opinion about my treatment options? How often should I have checkups?

Detection and diagnosis

Your doctor can check for breast cancer before you have any symptoms. During an office visit, your doctor will ask about your personal and family medical history. You'll have a physical exam. Your doctor may order one or more imaging tests, such as a mammogram.

Doctors recommend that women have regular clinical breast exams and mammograms to find breast cancer early. Treatment is more likely to work well when breast cancer is detected early.

Clinical breast exam

During a clinical breast exam, your health care provider checks your breasts. You may be asked to raise your arms over your head, let them hang by your sides, or press your hands against your hips.

Your health care provider looks for differences in size or shape between your breasts. The skin of your breasts is checked for a rash, dimpling, or other abnormal signs. Your nipples may be squeezed to check for fluid.

Using the pads of the fingers to feel for lumps, your health care provider checks your entire breast, underarm, and collarbone area. A lump is generally the size of a pea before anyone can feel it. The exam is done on one side and then the other. Your health care provider checks the lymph nodes near the breast to see if they are enlarged.

If you have a lump, your health care provider will feel its size, shape, and texture. Your health care provider will also check to see if the lump moves easily. Benign lumps often feel different from cancerous ones. Lumps that are soft, smooth, round, and movable are likely to be benign. A hard, oddly shaped lump that feels firmly attached within the breast is more likely to be cancer, but further tests are needed to diagnose the problem.

Mammogram

A mammogram is an x-ray picture of tissues inside the breast. Mammograms can often show a breast lump before it can be felt. They also can show a cluster of tiny specks of calcium. These specks are called microcalcifications. Lumps or specks can be from cancer, precancerous cells, or other conditions. Further tests are needed to find out if abnormal cells are present.

Before they have symptoms, women should get regular screening mammograms to detect breast cancer early:

• Women in their 40s and older should have mammograms every 1 or 2 years.

• Women who are younger than 40 and have risk factors for breast cancer should ask their health care provider whether to have mammograms and how often to have them.

If the mammogram shows an abnormal area of the breast, your doctor may order clearer, more detailed images of that area. Doctors use diagnostic mammograms to learn more about unusual breast changes, such as a lump, pain, thickening, nipple discharge, or change in breast size or shape. Diagnostic mammograms may focus on a specific area of the breast. They may involve special techniques and more views than screening mammograms.

Other imaging tests

If an abnormal area is found during a clinical breast exam or with a mammogram, the doctor may order other imaging tests:

• Ultrasound: A woman with a lump or other breast change may have an ultrasound test. An ultrasound device sends out sound waves that people can't hear. The sound waves bounce off breast tissues. A computer uses the echoes to create a picture. The picture may show whether a lump is solid, filled with fluid (a cyst), or a mixture of both. Cysts usually are not cancer. But a solid lump may be cancer.

• MRI: MRI uses a powerful magnet linked to a computer. It makes detailed pictures of breast tissue. These pictures can show the difference between normal and diseased tissue.

Biopsy

A biopsy is the removal of tissue to look for cancer cells. A biopsy is the only way to tell for sure if cancer is present.

You may need to have a biopsy if an abnormal area is found. An abnormal area may be felt during a clinical breast exam but not seen on a mammogram. Or an abnormal area could be seen on a mammogram but not be felt during a clinical breast exam. In this case, doctors can use imaging procedures (such as a mammogram, an ultrasound, or MRI) to help see the area and remove tissue.

Your doctor may refer you to a surgeon or breast disease specialist for a biopsy. The surgeon or doctor will remove fluid or tissue from your breast in one of several ways:

• Fine-needle aspiration biopsy: Your doctor uses a thin needle to remove cells or fluid from a breast lump.

• Core biopsy: Your doctor uses a wide needle to remove a sample of breast tissue.

• Skin biopsy: If there are skin changes on your breast, your doctor may take a small sample of skin.

• Surgical biopsy: Your surgeon removes a sample of tissue.

• An incisional biopsy takes a part of the lump or abnormal area.

• An excisional biopsy takes the entire lump or abnormal area.

A pathologist will check the tissue or fluid removed from your breast for cancer cells. If cancer cells are found, the pathologist can tell what kind of cancer it is. The most common type of breast cancer is ductal carcinoma. It begins in the cells that line the breast ducts. Lobular carcinoma is another type. It begins in the lobules of the breast.

Lab tests with breast tissue

If you are diagnosed with breast cancer, your doctor may order special lab tests on the breast tissue that was removed:

• Hormone receptor tests: Some breast tumors need hormones to grow. These tumors have receptors for the hormones estrogen, progesterone, or both. If the hormone receptor tests show that the breast tumor has these receptors, then hormone therapy is most often recommended as a treatment option.
• HER2/neu test: HER2/neu protein is found on some types of cancer cells. This test shows whether the tissue either has too much HER2/neu protein or too many copies of its gene. If the breast tumor has too much HER2/neu, then targeted therapy may be a treatment option.

It may take several weeks to get the results of these tests. The test results help your doctor decide which cancer treatments may be options for you.

You may want to ask your doctor these questions before having a biopsy: What kind of biopsy will I have? Why? How long will it take? Will I be awake? Will it hurt? Will I have anesthesia? What kind? Are there any risks? What are the chances of infection or bleeding after the biopsy? Will I have a scar? How soon will I know the results? If I do have cancer, who will talk with me about the next steps? When?

The breasts

The breasts

Inside a woman's breast are 15 to 20 sections called lobes. Each lobe is made of many smaller sections called lobules. Lobules have groups of tiny glands that can make milk. After a baby is born, a woman's breast milk flows from the lobules through thin tubes called ducts to the nipple. Fat and fibrous tissue fill the spaces between the lobules and ducts.

The breasts also contain lymph vessels. These vessels are connected to small, round masses of tissue called lymph nodes. Groups of lymph nodes are near the breast in the underarm (axilla), above the collarbone, and in the chest behind the breastbone.

Cancer cells

Cancer begins in cells, the building blocks that make up tissues. Tissues make up the breasts and other parts of the body.

Normal cells grow and divide to form new cells as the body needs them. When normal cells grow old or get damaged, they die, and new cells take their place.

Sometimes, this process goes wrong. New cells form when the body doesn't need them, and old or damaged cells don't die as they should. The buildup of extra cells often forms a mass of tissue called a lump, growth, or tumor.

Tumors in the breast can be benign (not cancer) or malignant (cancer). Benign tumors are not as harmful as malignant tumors:

Benign tumors:

• are rarely a threat to life

• can be removed and usually don't grow back

• don't invade the tissues around them

• don't spread to other parts of the body

Malignant tumors:

• may be a threat to life

• often can be removed but sometimes grow back

• can invade and damage nearby organs and tissues (such as the chest wall)

• can spread to other parts of the body

Breast cancer cells can spread by breaking away from the original tumor. They enter blood vessels or lymph vessels, which branch into all the tissues of the body. The cancer cells may be found in lymph nodes near the breast. The cancer cells may attach to other tissues and grow to form new tumors that may damage those tissues.

The spread of cancer is called metastasis.

Symptoms

Early breast cancer usually doesn't cause symptoms. But as the tumor grows, it can change how the breast looks or feels. The common changes include:Axls Closet Breast Cancer Overlay T Shirt black XL -Kids

• A lump or thickening in or near the breast or in the underarm area

• A change in the size or shape of the breast

• Dimpling or puckering in the skin of the breast

• A nipple turned inward into the breast

• Discharge (fluid) from the nipple, especially if it's bloody

• Scaly, red, or swollen skin on the breast, nipple, or areola (the dark area of skin at the center of the breast). The skin may have ridges or pitting so that it looks like the skin of an orange.

You should see your health care provider about any symptom that does not go away. Most often, these symptoms are not due to cancer. Another health problem could cause them. If you have any of these symptoms, you should tell your health care provider so that the problems can be diagnosed and treated.

What are the causes of breast cancer?

Breast cancer is the most common cause of cancer in women and the second most common cause of cancer death in women in the U.S. While the majority of new breast cancers are diagnosed as a result of an abnormality seen on a mammogram, a lump, or change in consistency of the breast tissue can also be a warning sign of the disease. Heightened awareness of breast cancer risk in the past decades has led to an increase in the number of women undergoing mammography for screening, leading to detection of cancers in earlier stages and a resultant improvement in survival rates. Still, breast cancer is the most common cause of death in women between 45-55 years of age. Although breast cancer in women is a common form of cancer, male breast cancer does occur and accounts for about 1% of all cancer deaths in men.
Research has yielded much information about the causes of breast cancers, and it is now believed that genetic and/or hormonal factors are the primary risk factors for breast cancer. Staging systems have been developed to allow doctors to characterize the extent to which a particular cancer has spread and to make decisions concerning treatment options. Breast cancer treatment depends upon many factors, including the type of cancer and the extent to which it has spread. Treatment options for breast cancer may involve surgery (removal of the cancer alone or, in some cases, mastectomy), radiation therapy, hormonal therapy, and/or chemotherapy.
With advances in screening, diagnosis, and treatment, the death rate for breast cancer has declined. In fact, about 90% of women newly diagnosed with breast cancer will survive for at least five years. Research is ongoing to develop even more effective screening and treatment programs.
