is Lymphoma? What
One main reason that cancer may develop is due to genetic errors. There are many different genes present in all cells and each one controls a different function in the body. When errors occur in the genes called genetic mutations that control cell division, the result is a cell that cannot divide normally.
This results in an abnormal cell that cannot properly perform its intended function. The cells of the immune system are constantly circulating in the body to identify and destroy these abnormal cells. However, in instances where the immune system does not work properly, or if the genetic mutation is too severe, these abnormal cells remain and grow at an uncontrolled rate.
Cancer is what occurs when these abnormal cells continue to grow at an uncontrolled rate. As these abnormal cells divide, they can create their own blood supply and form a solid mass called a tumour. A cancerous tumour will continue to grow at an uncontrolled rate and will eventually cause harm to other areas of the body.
The lymphatic system is a system of lymph nodes, vessels and organs that runs throughout the body, and often seems mysterious and elusive as it does not receive the same attention as other body systems, like the cardiovascular or digestive systems.
Individuals may be aware of lymph nodes in the neck when they become swollen with a sore throat or infection. The lymphatic system is a very important part of the body serving many life-preserving functions. Lymphocytes are a type of white blood cell and are a major component of the lymphatic system. Lymphocytes are divided into two types: They are an integral part of a healthy immune system. Normal functioning B-cells transform into highly specialised cells called plasma cells in the face of infection.
T-cells directly attack foreign invaders such as bacteria and viruses, and also kill cancer cells and rid them from the body. Lymphocytes can be found in the blood however, the majority of them are normally circulating within the lymphatic system.
Lymphoma is a cancer of the lymphatic system so understanding the lymphatic system and cancer in general makes it easier to understand. In lymphoma, a tumour develops due to uncontrolled growth of abnormal lymphocytes. Because the lymphatic system exists throughout the body and involves many organs, there may be cancerous tumours in many parts of the body when someone has lymphoma. Classic Hodgkin lymphoma is marked by the presence of cells known as Reed-Sternberg cells.
Other subtypes affect different types of cells. With treatment, more than 2 in 3 people diagnosed with stage I non-Hodgkin lymphoma will survive for at least 5 years.
