How is boxing health imparing?

Since I have already established that boxing is by far the more damagin sport I will focus on it instead of MMA for its health risk.

Cuts and bruises are the most common boxing injuries, and many boxers leave the ring needing stitches to the face and dental work. Body blows can lead to broken ribs and internal bleeding. Potentially blinding eye injuries can occur but may be difficult to detect except by specialist examination

The most serious of all risk is severe brain damage. This is to be expected when you have a powerful person constantly delivering blows to your head for upwards of 15 rounds. According to brain surgeons over 80% of all professional boxers have serious brain scarring on MRI scans. (Macnair)

     The British, American, Canadian and Australian Medical Associations have all called for an end to boxing, citing the high risk of brain damage and other injuries. The American Academy of Pediatrics has stated that boxing is an unsuitable sport for young athletes. Defenders of boxing assert that death rates from boxing-related injuries are low and that fighters are aware of the health risks involved. Sportswriter Harry Mullan has argued that improved medical care and awareness of safety procedures, rather than an all-out ban, are needed. (Holloway, 2011)
