A 19-year-old male asked:

how much does my cancer risk increase after a ct scan of the head as a teenager?

Almost no risk: Please see: http://www.scientificamerican.com/article/how-much-ct-scans-increase-risk-cancer/ also: 1) CT head exposure is mostly confined to the head, not the whole body. 2) There may be cellular repair at doses as low as CT, limiting cancer rates. (We don't know how much). 3) Whatever the theoretical risk, there must be a good reason to do the CT in the first place.

Rest, stretch, NSAID: Teens can have a variety of reasons for knee pain. Get checked by an orthopaedic surgeon for a definitive diagnosis. It can be growth related and self limiting requiring activity reduction at times and rest or anti-inflammatories. But, you much get checked to make sure its not a rare serious problem.

A 38-year-old female asked:

I am 38 f obese with fatty liver. I have lost 42 lbs since march . My hair is falling out. Could this be a sign of cirrhosis?

Probably not: Cirrhosis is not usually associated with hair loss.Any time there is a rapid reduction in weight or any kind of illness then we can see hair loss increase for several months. This type of hair loss comes back so not to worry. Good luck on your weight loss.
