Cancer survivors may face additional hurdles when trying to start a family.

Some cancer treatments may leave patients infertile, so they may turn to adoption.

Most agencies require the medical history of adoptive parents, a rule that some cancer experts say could discriminate against cancer survivors. 

A study from Moffitt Cancer Center in Tampa, Florida finds international adoptions had greater restrictions for prospective parents with a cancer history.

A growing number of young baseball players are undergoing surgery because of elbow overuse injuries.

Researchers at Rush University Medical Center in Chicago found that 56% of Tommy John surgeries performed between 2007 and 2011 were in teenagers.

Experts say the study suggests more young athletes believe having the surgery earlier may lead to the big leagues, even though very few high school ball players become professional players.

Many young athletes do go on to play college sports though and a new study suggests some surgeries early on may set them up for getting hurt during their college career.

In a study of more than 1,100 young athletes, UCLA researchers found those who had leg or knee surgery before college may be at higher risk for injury or another surgery. 

The most common procedures were knee arthroscopies.
