Malignant neoplasm of nasal cavity and paranasal sinuses (unspecified)
VA doesn't add ratings together. It combines them using the table in 38 CFR § 4.25, so two ratings usually total less than their sum.
While the cancer is active or treatment is ongoing, medical records confirming the diagnosis and documenting your treatment are the core evidence. Oncology notes, pathology reports, operative reports, radiation treatment records, and chemotherapy logs all establish that the 100 percent criteria are met. After the mandatory six-month post-treatment examination, the focus shifts to residuals. At that stage, imaging results, scope or biopsy findings, and physician notes addressing whether there has been any local recurrence or metastasis become critical. If no recurrence or spread is found, records documenting lasting effects — such as breathing difficulties, facial pain, vision changes, or speech problems — help VA rate those residuals accurately. Your own statements, and statements from people who know you, describing how remaining symptoms affect your work, sleep, and daily activities can also help show the severity of any residuals.
