This test assists in confirming a diagnosis of cancer found on x-ray or ultrasound or to diagnose certain inflammatory or immunological conditions.
The Three Sisters are a subgroup of the Cascade volcanoes west of Bend in central Oregon, consisting officially of North, Middle, and South Sisters (all approximately 10,000 ft high), though Mt. Bachelor (aka Bachelor Butte) & Broken Top are also in the immediate vicinity.
The Three Sisters route starts in Medina, TX. From Medina catch RR337 (at this point you are starting on The Three Sisters) heading west (right). Take RR337 west until you come up on the town of Leakey. At Leakey, go north on US 83 for a just about a mile and look for RR336 on the left.
