Cancer in lymph nodes can vary depending on whether it develops in the lymphatic system or spreads from other organs. Symptoms include enlarged lymph nodes, fever, night sweats, weight loss, and pain. Metastatic cancer can also cause new tumors to form in other areas.
Symptoms of cancer in the lymph nodes vary depending on whether the cancer has developed in the lymphatic system or has spread from elsewhere in the body. Lymphoma and leukemia are the most common cancers of the lymphatic system and can produce a variety of symptoms that can be distributed throughout the body in different related nodes and tissues. Tumors that grow in other tissues and then spread to and through the lymphatic system sometimes cause similar symptoms to develop.
The body relies on the lymphatic system to fight infection and make some of the blood components. This system is made up of an interconnected series of small knots spread throughout the body and is interconnected with the circulatory system. Cancer appears in the lymph nodes when it develops in the lymphatic system or when it spreads from other organs and tissues.
Tumors that form in the lymphatic system often produce one or more enlarged lymph nodes. These nodes can be tender or painless and often resemble lymph nodes that have swollen in response to a minor injury or infection. The spleen and liver are both connected to the lymphatic system, and these organs can also become inflamed, produce discomfort, or stop working properly due to cancer in the lymph nodes.
Systemic symptoms of cancer in the lymph nodes are common. A low-grade fever, night sweats and difficulty sleeping, as well as breathing problems may occur. Patients with this type of cancer often report loss of appetite. Weakness and unintentional weight loss are common, and problems with wound healing can occur. In some cases, pain in the abdomen, chest, or back can also be a symptom of cancer.
Some cancers form elsewhere in the body but then metastasize or spread to and through the lymphatic system. All body tissues are connected by the lymphatic and circulatory systems, so cancer cells from anywhere in the body can spread through local tissues and gain access to these systems. The cells that spread this way are still cells of the same type as the original tumor. Cancerous liver cells remain cancerous liver cells, but they can implant themselves in other regions of the body.
Cancer that has spread throughout the body will cause new tumors to form in other areas, often within the lymph nodes. The most notable symptoms of this cancer are often at the site of the initial tumor. In other cases, however, when the original tumor is small or located deep within the body, the first symptoms of metastatic cancer will appear elsewhere. Typically, when the lymph nodes are invaded by metastatic cancer, the symptoms are similar to those that occur when the lymph nodes are the primary site of a tumor.
