C85.98

Clinical Causes: Genetic mutations within lymphocytes that lead to uncontrolled cell growth. Immune system deficiencies, which can be inherited or acquired (such as from HIV/AIDS). Exposure to certain chemicals or pesticides, which may increase risk. Previous history of other cancers or radiation therapy, which might contribute to development. Age, with higher incidence rates seen in older adults, though it can occur at any age. Infections, such as certain viruses including the Epstein-Barr virus, may be associated with some types of NHL.

Key Symptoms: Swelling or lumps in the lymph nodes, typically painless, located in areas such as the neck, armpits, or groin. Unexplained weight loss and persistent fever. Night sweats, often severe enough to cause soaking during sleep. Fatigue and general weakness. Persistent cough, difficulty breathing, or chest discomfort if the lymph nodes in the chest are involved. Abdominal discomfort, pain, or swelling if lymph nodes in the abdomen are affected.

Diagnosis Path: Physical examination focusing on swollen lymph nodes and overall health status. Blood tests to evaluate overall health, blood cell counts, and to look for markers associated with lymphoma. Imaging studies such as CT scans, PET scans, or MRI to identify the extent and location of lymph node involvement. Lymph node biopsy, often through a surgical procedure, to examine tissue under a microscope and confirm the diagnosis. Bone marrow biopsy in some cases, to assess if the disease has spread to the marrow.

Treatment Protocols: Chemotherapy, which uses drugs to kill cancer cells and is often the main treatment. Immunotherapy, including targeted therapies that boost the body's immune response against the cancer. Radiation therapy, which employs high-energy rays to target specific areas of lymph node involvement. Stem cell transplants, considered in certain cases to allow for higher doses of chemotherapy. Clinical trials offering access to new and innovative treatments that may be effective.
