Indents on the skin after sleeping are normal; everyone gets them.
And excessive bruising is far more likely to be caused by anemia than by any sort of cancer. Luckily, anemia is easily treated.
But even if you aren't anemic, we all get bruises in the course of daily life, and sometimes we go through periods where we seem to get more of them than usual. Right now my shins are covered with bruises, and i have no idea why.
But I'm not too worried about it, because i know that if there were any sinister cause, i'd have a lot of other symptoms along with the bruising.
I'm sure you will be fine. Best wishes.
