Current research has not found lymphoma to have a very clear genetic predisposition or familial clustering. This is entirely different from familial breast cancer and colon cancer. Although there are many causes of lymphoma, and it is likely related to certain bacterial and viral infections, the mechanism of tumor occurrence is very complex. Infection is only one of the external factors, and currently, there is no evidence that lymphoma has tendencies for contagion or outbreaks. Therefore, as a relative of a lymphoma patient, the risk of developing lymphoma is not significantly higher than that of the general population, so there is no need for excessive worry.

Can lymphoma be cured?

Whether lymphoma can be cured depends on the specific pathological type of lymphoma, as there are dozens of subtypes, each with different prognoses and sensitivities to treatment. Additionally, the stage of lymphoma in patients also affects the prognosis. For example, patients with early-stage lymphoma can achieve a cure through radiotherapy and chemotherapy. However, for patients with advanced-stage lymphoma, treatment primarily involves chemotherapy, especially in cases of highly aggressive lymphoma, where it is difficult to achieve a complete cure. The goal of treatment in such cases is to alleviate pain and extend the patient's life.

Hodgkin's lymphoma symptoms and signs

Actually, whether it is Hodgkin's lymphoma or non-Hodgkin's lymphoma, the symptoms and signs are quite similar. In terms of symptoms, because lymphoma mainly occurs as a lesion in the lymph nodes, it is characterized by superficial, localized enlargement of the lymph nodes. Common locations include the neck, then the armpits, and the groin—areas where lymph nodes are more prevalent. It manifests as a local swelling; simply put, you might feel a lump or a tumor on your neck, which is the most common symptom. Additionally, there are other systemic symptoms including fever, weight loss, night sweats, and itchy skin, among others. As for the physical signs, it mainly refers to palpable superficial lymph node enlargement upon examination.

What are the early symptoms of lymphoma?

Lymphoma is a malignant tumor of the hematological system, with early symptoms including painless enlargement of the lymph nodes in the neck, which are generally well-movable and firm or hard in texture early on, without inflammatory changes such as redness, swelling, heat, or pain. Additionally, lymphomas occurring in the gastrointestinal tract can clinically present with symptoms such as upper abdominal fullness and discomfort, bloating, nausea, recurrent acid reflux, and belching. Lymphomas occurring in the respiratory system can manifest clinically with symptoms such as cough, shortness of breath after activity, and chest pain. Lymphomas occurring in the brain can cause dizziness, headaches, movement disorders, ataxia, and abnormal gait.

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.

The pattern of fever in lymphoma

Fever symptoms are quite common in patients with lymphoma, which we refer to as B symptoms. The pattern of their fevers is primarily low-grade, occurring more frequently in the afternoon or evening. Unlike ordinary bacterial infections, fevers in these patients do not respond well to anti-inflammatory drugs, but they do respond better to steroid treatment for reducing fever. However, if the lymphoma is not under control, their fever will repeatedly recur. Corresponding cooling treatments can reduce the temperature, but the fever will reoccur repeatedly. Only when the lymphoma and tumor are under control will the fever symptoms start to improve.
