Final answer:
Non-Hodgkin lymphoma (NHL), especially diffuse large B-cell lymphoma (DLBCL), is the type of lymphatic cancer that typically affects adults.
Step-by-step explanation:
The type of lymphatic cancer that typically affects adults is non-Hodgkin lymphoma (NHL), which is more common in adults than Hodgkin lymphoma (HL). NHL has many subtypes, with diffuse large B-cell lymphoma (DLBCL) being the most common. DLBCL predominantly affects B cells, which are a type of lymphocyte. Identifying the specific type of lymphoma is crucial for appropriate treatment, and for DLBCL, early detection and proper treatment can lead to a cure in about 70% of cases.
Lymphoma originates in the lymph nodes and affects lymphocytes, which are critical components of the immune system. B cells and T cells, the two main types of lymphocytes affected by lymphoma, play significant roles in adaptive immunity. Lymphoma can present with various symptoms, including fatigue, swollen lymph nodes, and in the case of DLBCL, fever and night sweats.
