| | | Risk Factors | | | | | The incidence of lymphoma in the U.S. has nearly doubled in the past 20 years, but the reason for this increase is unclear. People with weak immune systems, such as those with acquired immune deficiency syndrome (AIDS), congenital immune-deficiency disease or who have had organ transplants, are at greater risk for lymphoma. For example, people with AIDS are 50 to 100 times more likely to develop lymphoma than people who are not infected with HIV. Some researchers say part of the rise in lymphoma cases can be attributed to the increased use of herbicidal chemicals and, more controversially, to dark hair dyes. The data regarding this is not very convincing. Viruses have been linked to some forms of the disease.
Symptoms
The first symptom of Hodgkin's disease or non-Hodgkin's lymphoma is usually a swollen, firm and rubbery but painless lymph node in the neck, armpit or groin. One-third of people have symptoms that are felt throughout the body and are termed B symptoms. These symptoms include night sweats; itching; fever of more than 101.5 degrees F., especially in the late afternoon and evening; or loss of more than 10 percent of body weight.
