Preliminary questions [9831]

4931     there is some evidence that inhaling respirable asbestos fibres in an enclosed space may be a factor in the development of the condition under consideration.

32281  the condition under consideration is malignant neoplasm of the colon.

32257  the veteran has established the causal connection between inhaling respirable asbestos fibres in an enclosed space and operational service for the clinical onset of malignant neoplasm of the colorectum.

Clinical onset and operational service [32257]

32260 the veteran inhaled respirable asbestos fibres in an enclosed space for a cumulative period of at least 2000 hours at the time material containing such fibres was being applied, removed, dislodged, cut or drilled.

32261 the veteran inhaled respirable asbestos fibres in an enclosed space for a cumulative period of at least 2000 hours at the time material containing such fibres was being applied, removed, dislodged, cut or drilled before the clinical onset of the condition under consideration.

32262 where the veteran inhaled respirable asbestos fibres in an enclosed space for a cumulative period of at least 2000 hours at the time material containing such fibres was being applied, removed, dislodged, cut or drilled before the clinical onset of the condition under consideration, the first such inhalation occurred at least 10 years before the clinical onset of the condition under consideration.

33923 the veteran's inhalation of respirable asbestos fibres on operational service made a material contribution to the inhalation required by the Statement of Principles for malignant neoplasm of the colorectum.
