It could be bone cancer
Before you freak out, know that the chances of your bone pain being bone cancer are extremely slim. The American Cancer Association estimates only 2,970 new bone cancer patients will be diagnosed in 2015. (That's compared to more than 93,000 new cases of colorectal cancer .) Still, bone pain is a classic symptom of bone cancer (if a tumor is near a joint, you may notice swelling as well), and it's often worse at night or when you're active. Remember that symptoms can be similar to other conditions, like arthritis. And don't fear the worst—that it's cancer—if joint pain pops up. If the discomfort lingers longer than two weeks, see your doctor. It's likely that something else other than cancer is at the root of your pain, but it's best to have it checked out either way.
