Burn Pit Condition Clarification

VA clarification on presumptive conditions:

Only chronic diseases qualify. Acute and transitory conditions, which are not of a chronic nature, do not qualify for presumptive service connection
Only malignant tumors qualify for presumptive service connection for the established cancers
Benign neoplasm or any other non-malignant disease processes do not qualify under these presumptive diseases
Skin cancers, other than melanoma, only qualify for presumptive service connection if the location of the malignancy is the head or neck
All melanomas qualify for presumptive service connection, regardless of location
Sarcomas may only be considered for presumptive service connection if located in the head or neck areas, or located within a presumptive body system malignancy, such as renal sarcoma
Only primary cancers may be considered as a presumptive disease. Metastic or secondary cancers would not warrant service connection on a presumptive basis
