Lump found on leg is it cancer ?
It could also be a blood clot and it is essential you saw a doctor as soon as possible to have it checked.
Without much information beyond describing it as a lump, it is very hard to say. Like Jenny said, it could be a blood clot or it could be something worse than that. Rather than ask about it, you should go see a doctor about it because it is not going to clear itself up. I hope that it turns out to be nothing so please keep us posted on the diagnosis. Thanks for posting and I hope you do again soon.
benj; it may also be just a fatty tumor. seeing this question was about 4 months gone. anyway can you move it a little or is it hard?
