The liver, lungs, lymph nodes, and bones are common areas of spread or metastasis.
Metastasis is the spread of cancer cells to new areas of the body (often by way of the lymph system or bloodstream). A metastatic cancer, or metastatic tumor, is one which has spread from the primary site of origin (where it started) into different area(s) of the body. When the cancer has spread to other parts of the body, it is called metastatic cancer. The liver, lungs, lymph nodes, and bones are common areas of spread or metastasis. Even when cancer spreads to a new location, it is still named after the area of the body where it started. Metastasis, or metastatic disease, is the spread of a cancer or other disease from one organ or part to another not directly connected with it. The new occurrences of disease thus generated are referred to as metastases /mə ˈtaes ˈtæs tə/ (siːz sometimes abbreviated). mets Although advanced cancer may cause pain, it is often not the first symptom. Some patients, however, do not show any symptoms. When the organ gets a metastatic disease it begins to shrink until its lymph nodes burst, or undergo lysis. 1 Metastatic squamous neck cancer with occult primary is a disease in which squamous cell cancer spreads to lymph nodes in the neck and it is not known where the cancer first formed in the body. Signs and symptoms of metastatic squamous neck cancer with occult primary include a lump or pain in the neck or throat. Check with your doctor if you have a lump or pain in your neck or throat that doesn't go away. These and other signs and symptoms may be caused by metastatic squamous neck cancer with occult primary. When squamous cell cancer spreads to lymph nodes in the neck or around the collarbone, it is called metastatic squamous neck cancer. The doctor will try to find the primary tumor (the cancer that first formed in the body), because treatment for metastatic cancer is the same as treatment for the primary tumor. Signs and symptoms of metastatic squamous neck cancer with occult primary include a lump or pain in the neck or throat. Check with your doctor if you have a lump or pain in your neck or throat that doesn't go away. These and other signs and symptoms may be caused by metastatic squamous neck cancer with occult primary. This spread of cancer to a new part of the body is called metastasis. In order for cancer cells to spread to new parts of the body, they have to go through several changes. They first have to become able to break away from the original tumor and then attach to the outside wall of a lymph vessel or blood vessel. Treatment of cancer is based on the type of cancer a person has, and the stage of the cancer. Doctors use a system to assign a stage to the cancer. The most common staging system is the TNM system. The T in TNM stands for tumor, the M stands for metastasis, and the N stands for lymph nodes. Cancer that has spread from the primary (original) site to other places in the body is generally classified as advanced. When the cancer has spread only to nearby tissues or lymph nodes, it is called locally advanced cancer. When the cancer has spread to other parts of the body, it is called metastatic cancer. The liver, lungs, lymph nodes, and bones are common areas of spread or metastasis. Even when cancer spreads to a new location, it is still named after the area of the body where it started. For example, a person with breast cancer that has spread to the bones is said to have breast cancer with bone metastases In secondary or metastatic lymph node cancer, cancer cells from a malignant tumor of a distant organ travel to the lymph nodes via the lymphatic or blood vessels and lodge within the lymph nodes, where they continue to proliferate. 1 Signs and symptoms of the primary cancer may be present but sometimes detection of an enlarged lymph node may be the first sign of cancer. 2  For example – an enlarged left supraclavicular lymph node is often the first sign of stomach cancer.
