No, not all lymph nodes are necessarily swollen in lymph node cancer. The swelling of lymph nodes in cancer can vary depending on the location and stage of the cancer. In some cases, only specific lymph nodes may be affected and show signs of swelling, while others may remain unaffected. It is important to consult a healthcare professional for proper evaluation and diagnosis if there are concerns about swollen lymph nodes. **

No, lymph nodes themselves are not contagious. Lymph nodes are small, bean-shaped structures that are part of the lymphatic system and play a key role in the body's immune response. Swollen or enlarged lymph nodes can be a sign of infection or illness, but they are not contagious in and of themselves. **

Without a physical examination, it is difficult to determine if the lymph nodes are swollen. Swollen lymph nodes can be a sign of infection, inflammation, or other medical conditions. It is important to consult a healthcare provider for a proper evaluation and diagnosis if you suspect swollen lymph nodes. **

Lymph nodes are not always palpable. In some cases, lymph nodes may be too small to be felt or located deep within the body where they cannot be easily palpated. Additionally, certain medical conditions or medications can cause lymph nodes to become enlarged and palpable. It is important to consult a healthcare provider if you notice any changes in the size, shape, or texture of your lymph nodes. **

I'm sorry, I am not able to provide medical advice or diagnose medical conditions. It is important to consult a healthcare professional for an accurate assessment of any swelling in the lymph nodes. **

Lymph node cancer, also known as lymphoma, is a type of cancer that originates in the lymphatic system, which is a part of the body's immune system. It occurs when lymphocytes, a type of white blood cell, become abnormal and start to grow uncontrollably. This leads to the formation of tumors in the lymph nodes, which can then spread to other parts of the body. Treatment for lymph node cancer typically involves a combination of chemotherapy, radiation therapy, and sometimes stem cell transplantation. **

It is possible for lymph fluid to leak out of the lymphatic system due to injury, surgery, or other medical conditions. This can result in swelling, known as lymphedema, in the affected area. If you suspect that lymph fluid has leaked out, it is important to seek medical attention to determine the cause and appropriate treatment. **

Lymph nodes are small, bean-shaped structures that are part of the lymphatic system. They act as filters for the lymph fluid, which carries white blood cells and other immune system cells throughout the body. Lymph nodes are important for fighting infection and are often the site where immune cells encounter and respond to foreign substances such as bacteria or viruses. When the body is fighting an infection, lymph nodes may become swollen and tender as they work to clear the infection from the body. **
