Non-Hodgkin's lymphoma is a form of cancer that affects the lymphatic system. Like most cancers, this type of cancer strikes without warning. Many people are concerned about their health, and devote a lot of time and energy into adopting a healthy lifestyle that will reduce their risk of certain illnesses and cancers. For example, researchers and physicians have concluded that regular exercise and moderate consumption of meats reduces the odds of developing cancers. In addition, eating a healthy portion of certain fruits and vegetables are thought to also reduce the risk. However, despite lifestyle changes, illnesses such as cancer are very random and can strike anyone.

What is the Lymphatic System?

In order to have a better understanding of non-Hodgkin's lymphoma, one must also understand what the lymphatic system is, and how it works. The lymphatic system works in harmony with the body's immune system. Its primary function is to help the body fight infections. The lymphatic vessels connect to tissues in the body. Through these vessels travels lymph. Lymph is a fluid that consists of cells that fight infections. The lymphatic system also includes small organs called lymph nodes. These lymph nodes are located on various parts of the body including under the arm, neck, groin, chest, and abdomen.

What is Non-Hodgkin's Lymphoma?

Non-Hodgkin's lymphoma is cancer that begins in the cells of the lymph nodes. Cells are a vital part of life. In normal circumstances, cells will occasionally divide and spread. This is not an ongoing process. When we become ill or suffer injuries, healthy cells within our bodies die. It is only when this occurs that new cells form. The purpose of healthy cells is to fight infections and keep us healthy. On rare occasions, healthy cells will unnecessarily divide or grow. The abnormal growth of cells gradually forms a small mass or tumor. There are two types of tumors. Many automatically associate tumors with cancer. However, a large number of tumors are non-cancerous. Non-cancerous tumors, or benign tumors, develop from an overgrowth of healthy cells. When cells divide abnormally, and causes the death of healthy cells, the tumor is cancerous or malignant. Non-Hodgkin's lymphoma may develop in any part of body. If left untreated, this cancer may spread to other parts of the body such as the liver, spleen, or bone marrow.
