Malignant tumor of the colon (large intestine)
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.
During active disease or treatment, medical records confirming the diagnosis and documenting ongoing surgical, chemotherapy, radiation, or other therapeutic treatment are the core evidence. Oncology notes, pathology reports, operative reports, and treatment summaries all show that active disease or treatment is present and support the 100 percent rating. After treatment ends, the mandatory VA examination six months later becomes a central piece of evidence. At that point, records showing whether the cancer has recurred or spread are critical. If there is no recurrence or metastasis, evidence of residual disabilities matters most. This can include gastroenterology or surgical follow-up notes, imaging results, colonoscopy findings, lab work, and records of lasting effects such as bowel dysfunction, nutritional problems, or surgical complications. Statements from you describing how residual symptoms affect your daily activities and ability to work can help show the severity of those residuals.
