ok, at first, i had pain somewhere around the right tibia just above my ankle when i straighten my leg, but i donno whether is it bone pain, then when i touch, i feel a lump tat is not very sharp, when i press, there is quite a pain. about few weeks or one month later, the pain disappear regardless of straightening my leg or pressing the lump, but the lump is still there. i also encountered symptoms such as, firstly, there was a few times when i carry my bag and walk for few distant, my right middle tibia ache and pain, then when i rest for few mins, the pain disappear. secondly, sometimes,somewhere just below my right breast hurts, it hurts more when i breathe in, and i not sure is it the rib that hurts. thirdly, sometimes, when i lie down, my back hurts, after a few mins,it disappear,once again, i am not sure whether is it the spine that hurts.however, nowdays, the back pain seems to disappear. lastly, sometimes, my head suddenly feels numb. and, recently, when i stand with more force on my right leg and after that back to normal standing, my right pelvis area hurts for a while. now,are these symptoms of bone cancer?

The symptoms – bone pain at the site involved.
You must be specific. what type of bone cancer? Osteosarcoma?
Primary bone cancers are rare – only 2570 estimated in 2009 for the USA.
Most people have metastatic carcinomas to bones. that is stage four disease.
It is usually not curable then, but it depends on what the primary cancer is.
If you are not specific, you cannot obtain a specific answer.
