Lymphoma is a type of cancer that affects the white blood cells in the lymphatic system. It is one of the most common types of cancer, and it can be classified as either Hodgkin's lymphoma or non-Hodgkin's lymphoma. While it is not considered to be rare, the incidence of lymphoma varies depending on the type and location.
Incidence of Hodgkin's Lymphoma
Hodgkin's lymphoma is a relatively rare type of cancer, with approximately 8,500 new cases diagnosed in the United States each year. It affects about 2.1 in every 100,000 people in the United States. The incidence of Hodgkin's lymphoma is highest among young adults between the ages of 15 and 34 and is more common in men than in women.
Incidence of Non-Hodgkin's Lymphoma
Non-Hodgkin's lymphoma is much more common than Hodgkin's lymphoma, with approximately 72,000 new cases diagnosed in the United States each year. It affects about 21 in every 100,000 people in the United States. The incidence of non-Hodgkin's lymphoma increases with age, and it is more common in men than in women.
Factors Affecting Incidence
The incidence of both Hodgkin's lymphoma and non-Hodgkin's lymphoma is affected by a variety of factors, including age, gender, race, and family history. Additionally, exposure to certain chemicals and radiation, as well as certain viral infections, may increase a person's risk of developing lymphoma.
Overall, while lymphoma is not considered to be rare, the incidence of both Hodgkin's and non-Hodgkin's lymphoma varies depending on the type and location. It is important to speak with a healthcare provider if you have any questions or concerns about your risk of developing lymphoma.
