How Big Are Breast Cancer Tumors

What Does A Tumor Feel Like Under The Skin

The Big Four: Breast Cancer

Lumps, tumors, and all sorts of things one can feel in the breast can feel surprisingly similar: firm, as opposed to the normal, more spongy tissue of the breast. They are often irregularly shaped as opposed to a sphere or ball shape. Lumps are also usually mobile within the breast and can be moved around within the breast.

However, its important to note that this can vary from person to person. Ultimately, anytime you feel something thats different from what your normal breast tissue feels like, or if you notice anything that generally feels unusual, you should speak to your medical team about that.

What Is A Solid Tumor And How Is It Measured

There are two types of cancer solid tumor cancers and blood cancers. The definition of a solid tumor, according to the National Cancer Institute, is an abnormal mass of tissue that usually does not contain cysts or liquid areas. Solid tumors may be benign , or malignant . Different types of solid tumors are named for the type of cells that form them. Examples of solid tumors are sarcomas, carcinomas, and lymphomas. Leukemias generally do not form solid tumors.

Common solid tumor cancers include:AnalProstateThyroid

Sometimes, cancerous tumors are also called a nodule, growth, spot, met, lump or lesion. All of these terms are referring to a solid tumor. Solid tumors are visualized in CT scans, PET scans and MRIs. Radiologists measure their size in millimeters and centimeters and provide a measurement in 2 dimensions. For example, a radiologist may describe a tumor as being 3.0 cm x 2.7 cm. A lymph node may measure 1.2 cm x 1.0 cm. A small spot in our lung may be 8 mm x 11 mm.

Common Causes Of Benign Breast Lumps

Most benign breast lumps and conditions are directly related to your menstrual cycle, to fluctuations in your hormones, and to the fluid buildup that comes with your monthly period. Other benign breast lumps and conditions may be related to plugged milk ducts, infections, or even breast injuries. The risk for benign breast conditions increases for women who have never had children and those who have a history of irregular menstrual cycles or a family history of breast cancer.

Here are some of the most common benign breast conditions.

Fibrocystic changes These changes cause a general lumpiness that can be described as ropy or granular, and affect at least half of all women. Symptoms of fibrocystic change include tender, fibrous, rubbery tissue a thickening of tissue or a round, fluid-filled cyst. These changes, which are related to hormonal fluctuation, may increase as you approach middle age and disappear with menopause. Sometimes doctors recommend limiting salt and caffeine consumption to ease fluid buildup. Birth control pills may also ease symptoms.

Mastitis An infection of the milk duct, mastitis can create a lumpy, red, and warm breast, accompanied by fever. It occurs most commonly in women who are breastfeeding, but can occur in non-breastfeeding women as well. Treatment involves warm compresses and antibiotics. Because these symptoms are similar to inflammatory breast cancer, if they occur in a non-breastfeeding woman a doctor may want to do a biopsy.

How It Along With Other Factors Determines Your Treatment Options

Oliver Eng, MD, is a double board-certified surgeon and surgical oncologist and an Assistant Professor of Surgery at the University of Chicago.

Staging breast cancer and looking at lymph node involvement are essential for your oncology team to determine the extent of disease, treatment options, and prognosis.

Your oncologist likely uses the TNM staging system, developed by the American Joint Committee on Cancer and the Union for International Cancer Control , to conclude how these characteristics define a case of breast cancer.

You will be told the stage of your breast cancer usually at the start of your cancer journey, especially after you’ve had a breast biopsy, lumpectomy , or mastectomy .

This article will discuss the TNM staging system and its role in helping to diagnosis cancer stage and lymph node involvement.

What Is Stage Iii Breast Cancer

Fungating Breast Lesion

In stage III breast cancer, the cancer has spread further into the breast or the tumor is a larger size than earlier stages. It is divided into three subcategories.

Stage IIIA is based on one of the following:

  • 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.

In stage IIIB, a tumor has spread to the chest wall behind the breast. In addition, these factors contribute to assigning this stage:

  • 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 lymph nodes or to nodes near the breastbone.

In stage IIIC, there may be a tumor of any size in the breast, or no tumor present at all. But either way, the cancer has spread to one of the following places:

  • ten or more underarm lymph nodes
  • lymph nodes near the collarbone
  • some underarm lymph nodes and lymph nodes near the breastbone
  • the skin

How To Do A Breast Self

Performing a breast self-exam will help familiarize you with whats normal for your breasts. This can make it easier to notice any changes that may occur later on. If you menstruate, the best time for a self-exam is a few days after your period has ended.

Follow these steps when doing a self-exam:

  • Stand unclothed in front of a mirror. Keep your shoulders straight with your arms at your sides. Look for changes in the size, shape, or color of your breasts. Also look for swelling and nipple changes, including discharge.
  • Repeat with your arms raised.
  • Next, lie down and lift your right arm over your head.
  • Continue to examine your entire breast, from your collarbone to the top part of your abdomen, and from the center of your chest to your armpit. Try to follow a pattern so you cover your entire breast. Before you finish, gently squeeze your nipple to check for any discharge.
  • Finally, stand or sit up, lift your right arm over your head and massage your breast in a similar manner to the steps above. Doing this in a shower when your skin is wet may make it easier to feel your breasts.
  • Once youre done with one breast, switch sides and repeat. Try to do a self-exam once a month, around the same time each month.


If you notice anything unusual, call your doctor. A breast exam doesnt take the place of routine medical care and breast cancer screening.

See your doctor if you feel an unexplained lump in your breast or notice other changes, like:

How Is The Stage Determined

The staging system most often used for breast cancer is the American Joint Committee on Cancer TNM system. The most recent AJCC system, effective January 2018, has both clinical and pathologic staging systems for breast cancer:

  • The pathologic stage is determined by examining tissue removed during an operation.
  • Sometimes, if surgery is not possible right away or at all, the cancer will be given a clinical stage instead. This is based on the results of a physical exam, biopsy, and imaging tests. The clinical stage is used to help plan treatment. Sometimes, though, the cancer has spread further than the clinical stage estimates, and may not predict the patients outlook as accurately as a pathologic stage.

In both staging systems, 7 key pieces of information are used:

  • The extent of the tumor : How large is the cancer? Has it grown into nearby areas?
  • The spread to nearby lymph nodes : Has the cancer spread to nearby lymph nodes? If so, how many?
  • The spread to distant sites : Has the cancer spread to distant organs such as the lungs or liver?
  • Estrogen Receptor status: Does the cancer have the protein called an estrogen receptor?
  • Progesterone Receptor status: Does the cancer have the protein called a progesterone receptor?
  • HER2 status: Does the cancer make too much of a protein called HER2?
  • Grade of the cancer : How much do the cancer cells look like normal cells?

In addition, Oncotype Dx® Recurrence Score results may also be considered in the stage in certain situations.

How Are Measurements Calculated In The Metric System

Youve probably noticed the kilometer markings on your cars speedometer. Most over-the-counter medicines provide the dosage in milligrams for example, aspirin come in 81 mg and 325 mg sizes. Yet liquid medications are sold here in the U.S. utilizing ounces and teaspoon measurements. However, wine is sold in 750 ml and 1.5 liter sizes.

Its definitely confusing. People in the U.S. see both metric and the United States Customary System . We buy our meat in pounds and ounces and our wine in milliliters and liters.

However, all measurements within the U.S. medical system are metric. Because we are accustomed to a yard stick and a measuring tape that measure in inches, we are generally thrown for loop when we learn that we have a 4 cm tumor in our lung or breast. We dont know if thats large or small.

Meter = 39.37 inches . The meter is divided into 100 sections, called centimeters. Centimeter = 0.3937 inches, approximately 4/10th of an inch , about the diameter of a Cheerio. The centimeter is divided into 10 sections, called millimeters.Millimeter = 0.03937 inches, approximately the diameter of the lead in a wooden pencil

What Is A Cyst

A New Breast Cancer Treatment Could Be A Game Changer

A cyst is a fluid-filled sac that develops in the breast tissue. They most often happen in women between the ages of 35 and 50 and are common in those nearing menopause. The cysts often enlarge and become sore just before your period. They may seem to appear overnight. Cysts are rarely cancerous and may be caused by blocked breast glands.

Cysts can feel either soft or hard. When close to the surface of the breast, cysts can feel like a large blister, smooth on the outside, but fluid-filled on the inside. When they are deep in breast tissue, cysts will feel like hard lumps because they are covered with tissue.

Signs Of Cancerous Breast Tumors

Though most breast lumps are benign, some do turn out to be cancerous. If a tumor is cancerous, it will continue to grow and invade normal nearby tissue. If it isnt treated, it can spread to other areas in the body.

Most cancerous breast tumors first appear as single, hard lumps or thickening under the skin. Other signs to watch for include a change in nipple appearance, nipple secretions, nipple tenderness, and a dimpling or puckering of the skin.

About half of cancerous breast lumps appear in the upper, outer quadrant of the breast, extending into the armpit. About 18 percent of breast cancer tumors show up in the nipple area. Around 11 percent are found in the lower quadrant, and 6 percent are located in the lower, inner quadrant.

How Are Fibroadenomas Diagnosed And Treated

Your healthcare provider may diagnose this type of lump simply by feeling it. But, he or she will want to confirm the diagnosis with a mammogram or ultrasound and fine-needle aspiration. Sometimes, in very young women, the fibroadenoma is not removed. However, since sometimes these tumors enlarge with pregnancy and breastfeeding, your provider may suggest having it surgically removed.

While most fibroadenomas do not lead to cancer, there is a type of fibroadenoma that has been linked to an increased risk of cancer, particularly in women with a family history of the disease.

Size Surprise Tumour Size Nodal Status And Outcome After Breast Cancer

When it comes to tumour size, axillary lymph node status, and outcome after invasive ductal breast carcinoma, several facts have been established. The first is that the larger the tumour in diameter, the greater the number of axillary lymph nodes that will be found to be affected by metastatic cancer1. The second is that that the larger the tumour size, the worse the outcome1,2. The third is that the greater the number of lymph nodes involved by metastatic cancer, the worse the outcome1.

Tumour size and axillary lymph node status are highly correlated, but they are independent measures of outcome. Even in very large tumours, the number of involved lymph nodes highly significantly influences outcome, and when 4 or more nodes contain metastatic tumour, a woman with a 10- to 20-mm primary tumour has a better 5-year survival than does a woman with the same number of lymph nodes involved by cancer, but a primary tumour size of 2030 mm1.

So, what of Narods idea that the better course would be to focus efforts on lowering tumour sizes from 5 cm to 2 cmspecifically, by encouraging breast examination and mammography in developing countries and in poor and underserved populations in the developed world?

What Are The Stages Of Breast Cancer

Tumor Stage Still Influences Survival in Breast Cancer

There are two different staging systems for breast cancer. One is called anatomic staging while the other is prognostic staging. The anatomic staging is defined by the areas of the body where the breast cancer is found and helps to define appropriate treatment. The prognostic staging helps medical professionals communicate how likely a patient is to be cured of the cancer assuming that all appropriate treatment is given.

The anatomic staging system is as follows:

Stage 0 breast disease is when the disease is localized to the milk ducts .

Stage I breast cancer is smaller than 2 cm across and hasn’t spread anywhere including no involvement in the lymph nodes.

Stage II breast cancer is one of the following:

  • The tumor is less than 2 cm across but has spread to the underarm lymph nodes .
  • The tumor is between 2 and 5 cm .
  • The tumor is larger than 5 cm and has not spread to the lymph nodes under the arm .

Stage III breast cancer is also called “locally advanced breast cancer.” The tumor is any size with cancerous lymph nodes that adhere to one another or to surrounding tissue . Stage IIIB breast cancer is a tumor of any size that has spread to the skin, chest wall, or internal mammary lymph nodes .

Stage IV breast cancer is defined as a tumor, regardless of size, that has spread to areas away from the breast, such as bones, lungs, liver or brain.

What Are Dense Breasts

Breasts contain glandular, connective, and fat tissue. Breast density is a term that describes the relative amount of these different types of breast tissue as seen on a mammogram. Dense breasts have relatively high amounts of glandular tissue and fibrous connective tissue and relatively low amounts of fatty breast tissue.

How To Perform A Male Self

A person can perform the following steps:

  • Stand in front of a mirror with the arms at the hips. Tighten the chest muscles and check for any changes, including dimpling, swelling, or inverted nipples.
  • Raise the arms above the head and continue looking for breast changes.
  • Using the fingertip, move around the breast and armpit area in a circular motion to check for lumps.
  • Check the nipple for any discharge.
  • Complete this check for both sides.

    Tumor Size And Breast Cancer Staging

    Doctors determine the stage of cancer as part of their diagnosis. To confirm the breast cancer stage, they assess several different factors, including tumor size.

    Doctors use multiple tests and examinations to evaluate the specific characteristics of a persons breast cancer. They use this information to assign values to the TNM staging system, where:

    • T refers to the size of the main, or primary, tumor.
    • N refers to whether cancer has spread to nearby lymph nodes.
    • M refers to whether the cancer is metastatic, which means if it has spread to distant parts of the body.

    The overall stages of cancer range from 0 to 4. Stage 0 means the breast cancer is at a very early stage and has not yet spread. Stage 4 refers to late stage breast cancer, in which it has spread to other parts of the body.

    While every persons breast cancer is different, its stage generally indicates an individuals treatment options and outlook.

    People with early stage breast cancer are likely to have smaller tumors that doctors can easily treat. Larger tumors tend to indicate later stage breast cancer, which may be more difficult to treat.

    Doctors measure the size of the primary breast cancer tumor at its widest point. They usually give the size in millimeters or centimeters .

    According to the , doctors use the following system to grade tumor size:

    Tumor size is just one of several factors that doctors consider when determining the stage of a persons breast cancer. Other factors include the below.

    How Is Breast Cancer Treated

    Breast Cancer Overdiagnosis

    If the tests find cancer, you and your doctor will develop a treatment plan to eradicate the breast cancer, to reduce the chance of cancer returning in the breast, as well as to reduce the chance of the cancer traveling to a location outside of the breast. Treatment generally follows within a few weeks after the diagnosis.

    The type of treatment recommended will depend on the size and location of the tumor in the breast, the results of lab tests done on the cancer cells, and the stage, or extent, of the disease. Your doctor will usually consider your age and general health as well as your feelings about the treatment options.

    Breast cancer treatments are local or systemic. Local treatments are used to remove, destroy, or control the cancer cells in a specific area, such as the breast. Surgery and radiation treatment are local treatments. Systemic treatments are used to destroy or control cancer cells all over the body. Chemotherapy and hormone therapy are systemic treatments. A patient may have just one form of treatment or a combination, depending on her individual diagnosis.
