Additional Tools For Diagnosing Advanced Breast Cancer

Where Breast Cancer Starts and Spreads | How Breast Cancer Spreads | Nursing Exercise

The additional tools below are often used specifically for diagnosing advanced cancer:

Sentinel lymph node biopsy: This procedure removes sentinel lymph node cells during surgery for examination. When breast cancer spreads, it often heads first to the lymph nodes.

Chest X-ray: This detailed image of the chest may help doctors see whether cancer has spread to the bones.

Computed tomography scan: Also known as a CAT scan, this procedure takes detailed pictures of internal areas of the body using a computer linked to an X-ray machine. A dye may be used to help the organs show up more clearly in the images.

Bone scan: This procedure looks for bone metastasis, or cancer cells that have spread to the bone. A small amount of radioactive material is injected into the blood, then detected with a scanner.

Positron emission tomography scan: A PET scan is a detailed imaging tool that uses a radioactive drug, known as a tracer, to search for cancer cells within your body.

Stage Ii Breast Cancer

There are basically four sub-categories of breast cancer within the category of stage II. Breast tumors in the Stage II classification are:

  • A breast tumor that is 2cm in diameter or less. BUT the cancer cells have already spread to the lymph nodes.
  • OR a breast tumor that is larger than 5 cm but has not yet spread to the lymph nodes.
  • OR breast tumors in between 2 cm and 5 cm in diameter -whether there is evidence of spread to the lymph nodes or not.

There are actually quite a number of specific subcategories and letters and numbers to indicate a more precise description of the breast cancer at Stage II. .

In summary, stage II breast cancer is of intermediate size and threatening to spread. Without a doubt, staging for stage II breast cancers requires a thorough investigation of potential metastases.

Survival Rates for Stage II Breast Cancer

The average survival rate for stage II breast cancers is about 93% after five years and about 75% after 10 years. The rate of local recurrence is about 16% for stage II breast tumors. Furthermore, only about 16% of stage II breast cancers either have or will develop lymph node metastasis.

A baseline bone scan is unlikely to detect bone metastasis with stage 2 tumors, but they are usually necessary just to be sure.

Treatment for Stage II Breast Cancer

Treatment Of Noninvasive Cancer

For ductal carcinoma in situ, treatment usually consists of one the following:

  • A mastectomy

  • Removal of the tumor and a large amount of surrounding normal tissue with or without radiation therapy

Some women with ductal carcinoma in situ are also given hormone-blocking drugs as part of their treatment.

For lobular carcinoma in situ, treatment includes the following:

  • Classic lobular carcinoma in situ: Surgical removal to check for cancer and, if no cancer is detected, close observation afterward and sometimes tamoxifen, raloxifene, or an aromatase inhibitor to reduce the risk of developing invasive cancer

  • Pleomorphic lobular carcinoma in situ: Surgery to remove the abnormal area and sometimes tamoxifen or raloxifene to reduce the risk of developing invasive cancer

Women with lobular carcinoma in situ are often given tamoxifen, a hormone-blocking drug, for 5 years. It reduces but does not eliminate the risk of developing invasive cancer. Postmenopausal women may be given raloxifene or sometimes an aromatase inhibitor instead.

Dog Mammary Cancer Stages

There are five stages of mammary tumors in dogs. The stage of your pets cancer could help determine the right treatment, prognosis, and life expectancy.

The characteristics of each stage follow the tumor size , spread to regional lymph nodes , and distant metastasis .

Details on each stage are listed below:

Stage 1

  • Lymph node spread: Regional spread present
  • Distant metastasis: Distant metastasis present

What Happens When Breast Cancer Spreads To The Liver

When metastases spread to the liver they may cause abdominal pain, a feeling of fullness, weight loss, poor appetite, and jaundice, which is a yellowing of the skin. The symptoms result from the fact that the cancer cells interfere with the normal cells ability to make the liver work properly. The liver does much more than many realize. The liver makes chemicals for many bodily functions, stores nutrients, and detoxifies substances in the body.

Local And Regional Recurrence

Breast cancer that comes back in the skin of the breast where the cancer was first removed, or in the operation scar, is known as a local recurrence.

Breast cancer may also come back in the lymph nodes in the armpit, behind the breast bone, or in the lower part of the neck. This is called regional recurrence. If cancer cells are blocking the lymph nodes in the armpit, fluid can build up in the arm causing swelling known as lymphoedema.

Local and regional recurrences are not secondary breast cancer, as the cancer has not spread to another organ in the body.

These recurrences are usually less serious than secondary breast cancer. But you will usually have tests to find out if the cancer has spread to other parts of the body.

A local or regional recurrence that hasn’t spread anywhere else in the body may be treated with surgery, if possible, or with radiotherapy. Your treatment will depend on the treatments you received to remove and treat the primary breast cancer.

Where Does Breast Cancer Spread To

Metastatic breast cancer also called advanced or stage IV breast cancer is cancer that spreads to other parts of the body. Even when the breast cancer spreads to other organs of the body, it is still called and treated as breast cancer. Metastatic cancer can arise several months and even years after you have successfully treated early or locally advanced breast cancer. This often makes cancer patients wonder where breast cancer spreads to. Let’s find out more about it.

Phase Iii Keynote 355 Trial

How does cancer spread through the body? – Ivan Seah Yu Jun

The much anticipated KEYNOTE-355 trial was presented at the inaugural virtual ASCO annual meeting in June 2020. This trial investigated pembrolizumab/chemo vs chemo in patients with treatment-naïve, metastatic TNBC. Patients were excluded if they had active brain metastases or recurrence of disease < 6 mo prior to primary treatment. PD-L1 was assessed with the IHC 22C3 pharmDx CPS assay in a central laboratory. The primary outcome measure was pre-defined as OS and PFS in the PD-L1 positive population and the ITT population. In this trial, a hierarchial statistical testing method involved statistical testing of OS and PFS in the CPS > 10 group initially, followed by CPS > 1 and then the ITT population. The trial included 566 patients in the chemotherapy/IO arm vs 281 in the chemotherapy arm. In patients with a CPS score of 10 or greater, the median PFS favoured pembrolizumab with a PFS of 9.6 mo vs 5.6 mo . In patients with a CPS score of 1 or greater, the median PFS favoured the pembrolizumab arm with a PFS of 7.6 mo vs 5.6 mo . This was not statistically significant. This was similar to the ITT population where the PFS was 7.5 mo in the pembrolizumab arm and 5.6 mo in the placebo arm . OS data is awaited. This progression free survival improvement led to accelerated FDA approval for pembrolizumab in combination with chemotherapy in the first-line setting in November of 2020.

Treatment Of Breast Cancer In Men By Stage

This information is based on AJCC Staging systems prior to 2018 which were primarily based on tumor size and lymph node status. Since the updated staging system for breast cancer now also includes the ER, PR and HER2 status, the stages may be higher or lower than previous staging systems. Whether or not treatment strategies will change with this new staging system are yet to be determined. You should discuss your stage and treatment options with your physician.

Because there have been few clinical trials on treatment of male breast cancer, most doctors base their treatment recommendations on their experience with the disease and on the results of studies of breast cancer in women. With some minor variations, breast cancer in men is treated the same way as breast cancer in women.

The stage of your breast cancer is an important factor in making decisions about your treatment options. In general, the more the breast cancer has spread, the more treatment you will likely need. But other factors can also be important, such as:

  • If the cancer cells contain hormone receptors
  • If the cancer cells have large amounts of the HER2 protein
  • Your overall health and personal preferences
  • How fast the cancer is growing

Talk with your doctor about how these factors can affect your treatment options.

Symptoms Of Secondary Breast Cancer

The symptoms of secondary breast cancer depend on where in the body the cancer has spread to. If it has spread to the bones there might be a painful area in a bone. If it has spread to a lung it may cause breathlessness.

Some people have general symptoms. They may feel generally unwell for no obvious reason. Tell your doctor or nurse if you have any new symptoms. If you are worried, we have more information about the symptoms of secondary breast cancer.

What Are Lymph Nodes

Lymph nodes are small, rounded structures of about 1 mm to 25 mm that are found throughout the body.

The lymph nodes form part of the lymphatic system. The lymphatic system is an important part of the immune system that protects the body from disease and infection. It contains a network of thin tubes called lymph vessels that are found throughout the body. These lymph vessels transport a clear fluid called lymph between the lymph nodes. The lymph nodes filter the lymph to trap or remove substances harmful to the body, such as bacteria or cancer cells. This helps to protect the body from disease or infection. The lymph then passes back to the blood.

The closest lymph nodes to the breast are those in the armpit, which are known as axillary nodes. The axillary nodes drain lymph from nearby tissues, including the breast. There are also lymph nodes under the breastbone and in the neck . The number of lymph nodes varies between different people. There are usually about 15-30 lymph nodes in the armpit.

Because the lymph vessels carry lymph away from the breast, in the case of breast cancer, cancer cells can enter the lymph vessels and begin to grow in the lymph nodes. The axillary nodes are often the first place of cancer spread outside the breast. Usually, surgery is used to remove one or more of the axillary nodes to help check for cancer spread. Cancer found in the lymph nodes affects the staging and treatment of breast cancer.

Metastatic Breast Cancer Symptoms And Diagnosis

Can Men Get Breast Cancer?

The symptoms of metastatic breast cancer can vary greatly depending on the location of the cancer. This section covers the symptoms of breast cancer that has spread to the bone, lung, brain, and liver, and the tests used to diagnose metastatic breast cancer.

Bone Metastasis: Symptoms and DiagnosisThe most common symptom of breast cancer that has spread to the bone is a sudden, noticeable new pain. Breast cancer can spread to any bone, but most often spreads to the ribs, spine, pelvis, or the long bones in the arms and legs. Learn more.

Lung Metastasis: Symptoms and DiagnosisWhen breast cancer moves into the lung, it often doesnt cause symptoms. If a lung metastasis does cause symptoms, they may include pain or discomfort in the lung, shortness of breath, persistent cough, and others. Learn more.

Brain Metastasis: Symptoms and DiagnosisSymptoms of breast cancer that has spread to the brain can include headache, changes in speech or vision, memory problems, and others. Learn more.

Liver Metastasis: Symptoms and DiagnosisWhen breast cancer spreads to the liver, it often doesnt cause symptoms. If a liver metastasis does cause symptoms, they can include pain or discomfort in the mid-section, fatigue and weakness, weight loss or poor appetite, fever, and others. Learn more.

What Is Metastatic Breast Cancer

Metastatic breast cancer is not a specific type of breast cancer. Its the most advanced stage of breast cancer.

Metastatic breast cancer is breast cancer that has spread beyond the breast and nearby lymph nodes to other parts of the body .

Although metastatic breast cancer has spread to another part of the body, its still breast cancer and treated as breast cancer.

For example, breast cancer that has spread to the bones is still breast cancer . So, its treated with breast cancer drugs, rather than treatments for a cancer that began in the bones.

If Your Breast Cancer Has Spread

Even if your breast cancer has spread to other parts of your body, it does not necessarily mean its not treatable. If the cancer cannot be removed, the goal of treatment is to improve symptoms, improve quality of life and extend survival.

Some women live with breast cancer for several years as they learn to adjust and accept that theyll be on treatment for an indefinite period of time, explains Dr. Roesch. Your cancer team will help you learn and cope with what you can expect on this journey.

How Does Spreading Happen

There are several ways cancer can spread in the body.

  • Direct invasion happens when the tumor has spread to a nearby organ in the body. The cancer cells take root and begin to grow in this new area.
  • Lymphangitic spread occurs when cancer travels through the lymphatic system. Breast cancer often involves the nearby lymph nodes, so the cancer can enter the lymph circulatory system and take hold in different parts of the body.
  • Hematogenous spread moves in much the same way as lymphangitic spread but through the blood vessels. The cancer cells travel through the body and take root in remote areas and organs.

When cancer starts in the breast tissue, it may often spread to the lymph nodes before affecting other parts of the body. Breast cancer most commonly spreads to the:

  • bones

The type of test you end up having will depend on your medical history and symptoms. For example, if you or your doctor suspects the cancer may have spread to your abdomen, you may have an ultrasound.

CT and MRI scans can help your doctor visualize various parts of the body all at once. A PET scan can be helpful if your doctor thinks the cancer may have spread but isnt sure where.

All of these tests are relatively noninvasive, and they shouldnt require a hospital stay. You may be given special instructions before your test.

If you have a CT scan, for instance, you may need to drink an oral contrast agent to help outline different features inside your body.

If All The Cancer Was Removed With Surgery Why Do I Need Any Additional Treatment

Metastasis: How Cancer Spreads

It has long been recognized that breast cancer is not always cured by locoregional treatment alone.

The goal of treating early breast cancer is to remove the cancer and keep it from coming back . Most people diagnosed with breast cancer will never have a breast cancer recurrence. However, everyone who has had breast cancer is at potential risk of recurrence, and that is why in most cases, there is a recommendation for treatment in addition to surgery, which is known as adjuvant therapy. The risk of recurrence can never be entirely eliminated, but the aim of adjuvant therapy is to reduce recurrence risk to the absolute minimum.

Stages Of Breast Cancer

The stage of breast cancer is based on the size and location of the tumor, as well as whether the cancer has spread beyond the part of the breast in which it originated. To determine the stage of breast cancer, healthcare professionals use a scale of stage 0 to stage 4.

Stage 0 breast cancers are isolated in one part of the breast, such as a duct or lobule, and show no sign of spreading into other tissue.

Stage 1 is typically localized, although further local growth or spread may cause the cancer to move into stage 2.

In stage 3, the cancer may be larger and has affected the lymph system. Stage 4 cancer has spread beyond the breast and nearby lymph nodes, and into other organs and tissues of the body.

In addition to stages, breast cancers are given grades based on the size, shape, and activity of the cells in the tumor. A higher-grade cancer means a greater percentage of cells look and act abnormal, or they no longer resemble normal, healthy cells.

On a scale of 1 to 3, with 3 being the most serious, TNBC is often labeled grade 3.
