Malignant primary bone tumors are characterized as either bone cancers which originate in the hard material of the bone or soft-tissue sarcomas which begin in blood vessels, nerves, or tissues containing muscles, fat, or fiber.
For example, a person with severe joint arthritis, back pain or soft-tissue injuries can exercise much more comfortably in a pool than on land thanks to water's cushioning effect.
In addition to fractures, external injuries of the nose include soft-tissue injuries resulting from bites (human and animal), insect stings, cuts, or scrapes.
In non-contact sports, major fractures, dislocations, or soft-tissue injuries are usually associated with accidental rather than intended collisions.
Soft-tissue sarcomas are malignant tumors of the muscle, nerves, joints, blood vessels, deep skin tissues, or fat.
