Why are the liver and lungs a common site for metastasis?

The liver, in particular, provides a fertile soil for metastatic spread because of its rich blood supply and the presence of humoral factors (other bodily fluids) that promote cell growth. In terms of blood flow per minute, the blood supply of the liver is second only to the lung.

How does metastasis relate to cell cell association and interaction with the extracellular matrix?

The metastatic cascade is therefore dependent on the loss of adhesion between cells, which results in the dissociation of the cell from the primary tumor, and subsequently the ability of the cell to attain a motile phenotype via changes in cell to matrix interaction.

How might this type of cancer metastasize ie spread to other parts of the body )? In other words by which routes might the cancer cells reach other organs?

Metastases can occur in three ways:

• They can grow directly into the tissue surrounding the tumor;
• Cells can travel through the bloodstream to distant locations; or.
• Cells can travel through the lymph system to nearby or distant lymph nodes.

How do cancer cells metastasize to other organs?

In metastasis, cancer cells break away from where they first formed, travel through the blood or lymph system, and form new tumors in other parts of the body. Cancer can spread to almost anywhere in the body. But it commonly moves into your bones, liver, or lungs.

Can you survive liver metastases?

Prognosis for liver metastases tends to be poor, with a roughly 11\% survival rate for 5 years. Treatments can help reduce the symptoms and shrink the tumor, but typically, there is no cure for liver metastases.

Are liver metastases painful?

Many people don’t notice anything unusual to indicate that they’ve developed liver metastases. Some say they feel some abdominal discomfort or pain. You may also have one or more of the following signs or symptoms: an overall feeling of weakness and poor health.

What is the difference between metastasis and metastases?

Metastases is the plural form of metastasis. Metastases most commonly develop when cancer cells break away from the main tumor and enter the bloodstream or lymphatic system.

How do tumors metastasize?

Metastatic cancer is a cancer that has spread from the part of the body where it started (the primary site) to other parts of the body. When cancer cells break away from a tumor, they can travel to other parts of the body through the bloodstream or the lymph system.

Why do cancer cells metastasize?

Cancer metastasizes due to several factors, namely attack by the immune system, lack of oxygen and necessary nutrients, large amounts of lactic acid produced by glycolysis and increased cell death. Therefore, the majority of the presently available treatments for cancer also bear the potential to induce metastasis.

What is metastatic breast carcinoma?

When breast cancer spreads to an area farther from where it started to another part of the body, doctors say that the cancer has “metastasized.” They call the area of spread a “metastasis,” or use the plural of “metastases” if the cancer has spread to more than 1 area. The disease is called metastatic breast cancer.

Can chemo get rid of liver mets?

Given before surgery, chemotherapy can lower the risk of tumors coming back later on. Chemotherapy can also help shrink liver metastases from the colon and rectum so that they’re safer for a surgeon to take out.

Can breast cancer metastasize to the bones?

For more than half of women who develop stage IV breast cancer, the bones are the first site of metastasis. Although breast cancer can spread to any bone, the most common sites are the ribs, spine, pelvis, and long bones in the arms and legs. A sudden, noticeable new pain is the most common symptom of cancer that has spread to the bone.

Where do metastatic breast tumors spread to?

The most common locations for metastatic breast tumors include the: Even if breast cancer spreads to a distant organ, it is still classified as breast cancer. For instance, breast cancer that spreads to the lungs is considered to be metastatic breast cancer – not lung cancer.

Can breast cancer metastasize to the brain?

However, for about 17\% of women in this group, the brain is the only site of metastasis. The risk of cancer spread to the brain is usually highest for women with more aggressive subtypes of breast cancer, such as HER2-positive or triple-negative breast cancer.

What are the symptoms of lung metastases in breast cancer?

Just as the blood is filtered by the liver, blood passes through the lungs, making this a common site of breast cancer metastasis. The most common symptom of lung metastases is shortness of breath, which may be mild and only occur with exercise at first. Other symptoms can include a persistent cough or pain with breathing .
