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.

What are the symptoms of lymphoma?

The symptoms of lymphoma predominantly start with painless enlargement of superficial lymph nodes, most commonly in areas such as the neck, supraclavicular lymph nodes, armpits, or groin. Additionally, patients with nasal NKT lymphoma might experience nasal congestion, nosebleeds, and rhinorrhea. Lymphomas occurring in the stomach, for example, present symptoms like nausea, vomiting, and even rectal bleeding which are related to the gastrointestinal tract. Therefore, symptoms can vary depending on the location of the lymphoma. Some patients may also experience enlargement of the liver and spleen. In advanced stages of lymphoma, bone marrow involvement is possible, along with common B symptoms including sweating, fever, or weight loss, which are also clinical manifestations seen in lymphoma patients.

What is lymphoma?

Lymphoma refers to a type of malignant tumor that originates in the lymph nodes or extranodal tissues or organs. It is clinically categorized into two main types: Hodgkin's lymphoma and non-Hodgkin's lymphoma. Furthermore, it can be subdivided into many different pathological types. Among these, diffuse large B-cell lymphoma is the most common type in China, and there are dozens of different pathological types. The pathological type of the lymphoma determines its malignancy level, prognosis, chemotherapy regimen options, and treatment methods, all of which can vary significantly.

Malignant lymphoma chemotherapy regimen

The chemotherapy for malignant lymphoma, I personally don't think is very painful. Actually, lymphoma treatment nowadays not only includes chemotherapy but also targeted therapy and immunotherapy, so it is not very painful. Moreover, generally speaking, the common side effects of chemotherapy include nausea, vomiting, fatigue, poor spirit, constipation, or diarrhea. In clinical practice, these symptoms can be controlled by using antiemetic, hepatoprotective, gastric protective, and cardioprotective drugs. Of course, another common side effect of lymphoma chemotherapy is bone marrow suppression, which can cause a decrease in white blood cells and platelets. However, if there is only a mild decrease, we can restore these levels with oral medication to increase white blood cells or injections to increase white blood cells and platelets. If the suppression is very severe, it could potentially be life-threatening. But strictly speaking, more than 95% of patients can tolerate chemotherapy.

Typical symptoms of lymphoma

Typical symptoms of lymphoma include night sweats, fever, and weight loss. This fever often occurs in the afternoon, characterized as a cyclical fever that lasts for several days with irregular patterns. There are fever-free intervals ranging from a few days to several weeks, almost a nonspecific symptom but not commonly seen. Fever, night sweats, and unexplained weight loss of more than 10% within six months, or even emaciation, are considered B symptoms and are associated with a poor prognosis. In addition, skin itching is also not uncommon in late-stage patients.
