Final answer:
Primary malignant nodes in lymphoma tend to enlarge, and if they contain cancerous cells, they can lead to regional spread of the cancer through the lymphatic system. Symptoms such as fever and night sweats may accompany the enlargement of lymph nodes. Early detection and treatment are key in managing the disease effectively.
Step-by-step explanation:
Primary malignant nodes, like in lymphoma, tend to become more enlarged, which could be an indication of the presence of cancerous lymphocytes. Malignant tumors can grow beyond their original location and potentially spread to other parts of the body through metastasis. In the case of lymphoma, swollen lymph nodes serve as a common symptom and are part of the lymphatic system, which filters lymph and contains lymphocytes that help fight infections.
Cancer cells can spread from their site of origin to regional lymph nodes and other tissues via the lymphatic system, and as the cancer progresses, symptoms like fever, night sweats, weight loss, and loss of appetite can also arise. Lymphoma can be aggressive and fast-growing, but with early detection and appropriate treatment, the prognosis can be greatly improved.
