Is lymphoma contagious?
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 usually involve painless, progressive enlargement of the lymph nodes, typically located in areas like the neck, under the jaw, and below the chin. However, beyond these localized symptoms, lymphoma can also present with systemic symptoms, which include fever, night sweats, weight loss, as well as rashes and itching skin. Thus, lymphoma encompasses both local and systemic symptoms.
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.
Is lymphoma hereditary?
Lymphoma is generally not hereditary, as it is not a genetic disease. However, I must mention that most neoplastic diseases do have some hereditary factors to some extent. The reason for this is that the cause of lymphoma is currently unclear, and it may be related to genetic mutations, which raises the issue of heredity. Another point is that heredity often refers to transmission among direct relatives. This means there could be a problem in that you might share similar environments and lifestyles, including diet. If there are factors in your diet or living environment that could trigger lymphoma, and you are both exposed to these factors, then your probability of developing lymphoma could indeed be higher than in patients without a family history, leading to such a concern.
How is malignant lymphoma treated?
The common treatments for malignant lymphoma currently include chemotherapy, targeted therapy, radiation therapy, and the use of immunosuppressants. There are also newer treatments such as cell reinfusion. The choice of treatment for malignant lymphoma definitely depends on the specific pathological type. Another factor is the stage of the lymphoma—it could be in stages one, two, three, or four, which definitely matters. The third factor is whether the lymphoma causes any symptoms or signs in the patient because some minor lymphomas may allow for observation and waiting, but many require active treatment.
Male breast cancer generally occurs at what age?
The general age of onset for male breast cancer is between 65 and 67 years old, which is about five to ten years later than the onset age for female breast cancer. Male breast cancer is a relatively rare malignancy, accounting for only 0.6% to 1% of all breast cancer cases, meaning that out of 100 breast cancer patients, approximately one is male. The development of male breast cancer is caused by multiple factors, which may include genetic factors, environmental influences, and also related to levels of hormone secretion from the endocrine system.
What is lymphoma Ki-67?
Lymphoma Ki67, also known as the proliferation index, is one of the indicators in immunohistochemistry performed after the pathological diagnosis of lymphoma. If this proliferation index is higher, it indicates that the activity of the tumor is stronger, and its proliferation is more active, thus the tumor should be given sufficient attention. Of course, active treatment should be pursued. Therefore, Ki67 reflects the activity of a tumor; if the index is very high, greater than 90%, it sometimes implies that the tumor can grow very rapidly, or not only grows significantly but might also spread to many places.
What are the symptoms of lymphoma spread?
The symptoms of lymphoma spread depend primarily on its original location. Generally, the most common site of origin is in the neck. Spread means that it has moved to other areas, so it may have spread to the armpits, groin, or popliteal fossa. If there is swelling or a tumor in the lymph nodes in these areas, it manifests as a tumor that can be felt in those specific locations, like in the groin or armpits. Of course, it is possible that it may spread to substantive organs, such as the lungs. If it spreads to the lungs, symptoms might include shortness of breath, coughing, and blood in the sputum.
Lymphoma rash symptoms
The rash associated with lymphoma is not much different from common rashes; they are both characterized by red papules. However, lymphoma is not an isolated disease. For instance, in patients, one can feel lumps on the neck or upper clavicle area, but they may also exhibit systemic symptoms such as fever, night sweats, weight loss, fatigue, lack of appetite, anemia, chest pain, and other symptoms because it is a systemic disease. Thus, it may cause these systemic symptoms. The rash can also cause itching of the skin.
Is primary liver cancer hereditary?
Primary liver cancer is usually not hereditary, but the reason why it tends to appear in families in China is mainly due to the widespread infection of hepatitis B virus, which then leads to a significant correlation with hepatic cirrhosis caused by hepatitis B. It is well known that the hepatitis B virus is contagious and can easily be transmitted within families and from mother to child. Therefore, it is not uncommon to see several cases of liver cancer within the same family, indicating a familial aggregation. Another factor is related to dietary habits, for example, the infection of aflatoxin, which is mainly found in moldy peanuts. If the dietary habits within a family are similar, then, of course, the likelihood of occurrence is certainly higher.
