Worried of leukemia. Help?

I got a TON of Mosquito bites on my legs. I was scratching them a lot and sometimes semi hard until I got some cream. I noticed today I have a bruise in the area where I was scratching.

Is this normal, has it happened to you? I'm such a hypochondriac. I have a cancer phobia and I've researched all the cancers in the past. I know with Leukemia you bruise easily. Would that be classified as easy?

Or is this nothing to worry about?

This has happened to me before...from insect bites...and just random itching.....I will scratch so much that I end of with bruising.  Not sure what it means....I generally bruise easily anyway....Just wanted to let you know you weren't alone!  I've had lots of blood work done for other things....and the doctors have never said anything was abnormal.

Most of the time, if a person has leukemia it will include other smptoms such as fatigue, bone pain, weight loss, and bleeding from the gums. If you're having any of these symptoms it may be a good idea to see your doctor- if for no other reason than for your own peace of mind.
