The Board has determined that the Veteran's thyroid cancer, vitamin D deficiency, asthma, and obstructive sleep apnea are not service-connected as they did not begin during active service or are otherwise related to an in-service injury or disease.
The deciding factor: The evidence does not support a finding of direct service connection for any of the conditions due to lack of medical nexus between the claimed disabilities and service.
