Malignant neoplasm of lymphatic system (any site)
To support a 100% rating while the disease is active or during treatment, medical records showing a confirmed diagnosis of Non-Hodgkin's lymphoma and documentation of ongoing or recent treatment — such as chemotherapy records, radiation therapy summaries, or surgical reports — are central. For low-grade NHL rated as indolent and non-contiguous, pathology reports and imaging studies that characterize the stage and behavior of the disease help show that condition.
After treatment ends, records that mark the exact date treatment was discontinued matter because that date starts the two-year continuation period. Oncology notes, imaging results, and lab work showing whether the disease has recurred or is in remission are relevant at the mandatory two-year examination.
If the cancer has not recurred and VA moves to rate residuals, evidence shifts to whatever lasting effects remain — such as records documenting fatigue, neuropathy, organ damage, or other lasting effects tied to the disease or its treatment. Statements from you and people who know you describing how those residual symptoms affect your daily life and ability to work can also reflect what the medical records show.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
