Lymphoma is not contagious, as it is not an infectious disease but a tumoral disease. Therefore, it is not contagious, and when seeking medical treatment for lymphoma, patients do not go to the department of infectious diseases. Typically, treatment is conducted in the oncology department or in the hematology department specializing in lymphoma. Thus, lymphoma is not contagious because it is not caused by an infectious pathogen. It is a solid tumor that is tangible and visible.

Lymphoma fever symptoms

Patients with lymphoma commonly exhibit symptoms such as fever, clinically referred to as B symptoms. Some patients may also experience additional B symptoms such as fatigue, sweating, or weight loss. Patients displaying these B symptoms generally have a poorer prognosis. Furthermore, lymphoma patients typically experience fever more frequently in the afternoon or evening, usually presenting with a low-grade fever. If the condition of a lymphoma patient is not controlled, their fever symptoms will recur repeatedly. Only when the condition is under control will there be an alleviation of fever symptoms. Anti-inflammatory drugs are not effective in these cases.

Is lymphoma the same as lymphatic cancer?

Lymphoma refers to a type of malignant tumor that originates in lymph nodes or extranodal tissues or organs. The cancer we usually talk about refers to malignant tumors originating from epithelial tissues, which we call cancer, such as lung cancer, liver cancer, etc. Therefore, lymphoma is actually what non-medical professionals commonly refer to as lymphatic cancer. It is simply called lymphoma instead of cancer because it originates in lymph nodes or extranodal tissues or organs, and therefore, it is termed malignant lymphoma, which in layman's terms is lymphatic cancer.

Causes of Malignant Lymphoma

The causes of malignant lymphoma are the result of multiple factors. First, it is associated with infections by bacteria or viruses, such as the well-documented chronic infection with Helicobacter pylori, which is closely related to the occurrence of lymphoma associated with the gastric mucosa. Second, immunodeficiency conditions, like in AIDS patients or those who have been taking immunosuppressive drugs for a long period, have a higher likelihood of developing malignant lymphoma compared to the general population. Third, chemical or physical factors, such as environmental carcinogens and electromagnetic radiation, can also lead to malignant lymphoma. Other factors, such as long-term use of certain drugs like phenytoin or pseudoephedrine, and a genetic predisposition, can also be causes of malignant lymphoma.

How is Hodgkin's lymphoma treated?

The treatment of Hodgkin's lymphoma is based on various factors including the stage of the disease as well as the general condition of the patient, among other comprehensive considerations. For patients with early stage Hodgkin's lymphoma, commonly referred to as localized Hodgkin's lymphoma, the treatment principle is a combination of chemotherapy and radiotherapy. A rational comprehensive treatment can achieve a five-year survival rate of 80% to 90%. For advanced-stage patients, such as those with stage IV Hodgkin's lymphoma, the treatment primarily consists of systemic chemotherapy. Therefore, the choice of a specific treatment plan must also consider a variety of factors based on the patient's overall condition.

Lymphoma has what manifestations?

The symptoms of lymphoma, simply put, are that some people feel a lump on their neck or in their armpit; it starts as a sudden appearance of a swelling that gets larger over time, sometimes not just one, but multiple lumps clustered together. This is indeed the most common symptom, where one can feel something on their neck, including under the jaw or the chin, noticing suddenly a nodule has formed, whether it's the size of a chicken egg or otherwise. That's one aspect. The second involves systemic symptoms, which primarily include fever, night sweats, and weight loss. These three symptoms are quite common.
