Every human body consists of a network of lymph vessels and lymph nodes. This network helps to collect all fluids and other things that are present in the tissues of the body. These lymph vessels act like veins that help to collect all the blood throughout the body. But lymph nodes instead of collecting blood, carry the watery fluid known as lymph.
These lymph nodes help to transfer the fluid through the nodes that are present all over the human body. Lymph nodes are small parts that act like filters for removal of all harmful substances.
Signs and Symptoms
Certain symptoms are not specific to lymphoma and are, in fact, similar to those of many other illnesses. People often first go to the doctor because they think they have a cold, the flu or some other respiratory infection that does not go away.
Common symptoms include
Swelling of lymph nodes, which may or may not be painless
• Unexplained weight loss
• Sweating (often at night)
• Lack of energy
Most people who have these non-specific symptoms will not have lymphoma. However, it is important that anyone with persistent symptoms be examined by a doctor to make sure lymphoma is not present.
Cancer in the Lymph Nodes
Cancer can come up in lymph nodes by either entering into lymph nodes from other organs or they may start from there. When the cancer starts in the lymph nodes then it is known by the term lymphoma.It spreads from where it started to other organs in the body. When the cancer cells break away from a tumor then they can pass onto other organs in the body through the bloods or the lymph nodes. Some distant organs can also come under access of the cancer cells.
But in both cases, most of the cancer cells dies or killed before they can start developing in some other part of the body. When any one or two start growing in another part of the body then they form new tumors and this process is called upon by the name metastasis.
Body Changes in Lymph Node Cancer
When cancer cells spread to other parts of the body then they pass through several changes like they become able to detach from the original tumor and can attach themselves to the blood vessel walls. Another change is that they have to pass through the walls of the blood vessels to provide blood or lymph to other lymph nodes and body parts.
When the cancer cells start growing in the lymph nodes then the lymph nodes of the tumor are the first one to get affected and actually these are the nodes that help to remove other cancer cells.
Types of Lymph Node Cancer
There are many different types of lymphoma depending on the type of lymphatic cells affected.
Hodgkin’s lymphoma can occur at any age, affects more men than women and the majority will be completely cured.
Hodgkin’s lymphoma is diagnosed when a special type of cell, the Reed-Sternberg cell, is seen under the microscope.5
Non-Hodgkin’s lymphoma accounts for all the other types of lymphoma. These can be high grade or low grade and the treatment and prognosis varies
