The exact symptoms of bone cancer will vary, depending on the size of the cancer and where it is in the body. Common symptoms include: pain, swelling and problems with movement.
​

• Pain and tenderness will be around the area of the bone tumor. The pain is often worse at night.

• Swelling may not show up until the bone tumor is quite large. You cannot always feel, or see a lump. This depends on where the cancer is.

• If the cancer is near a joint, the lump can get in the way and make it more difficult for you to move. You may develop a limp if a leg bone is affected.

• Tiredness, fever and weight loss are all general symptoms that can occur with a number of conditions, including cancer.

Sarcomas & Grade
 
The grade tells you how normal or abnormal the cells of a tumor appear to be. It is decided by looking at cells from your cancer under a microscope. The grade gives your doctor an idea of how quickly or slowly your cancer is likely to grow. A sample of the cancer (a biopsy) must be taken before your sarcoma can be graded as either.
​

• Grade 1 - the cells do not look that different to normal cells

• Grade 2 - the cancer cells look moderately abnormal

• Grade 3 or 4 - the cancer cells look very abnormal and not much like normal cells

​
Grade 1 and 2 are defined as low grade. Grade 3 and 4 are high grade. A low grade cancer is likely to be slower growing and less likely to spread to another part of the body.
​
A high grade cancer is likely to be faster growing and is more likely to spread than a low grade sarcoma. After the diagnosis is final and the grade has been determined you will most likely be advised to have a surgical procedure, or begin a chemotherapy or radiation treatment to kill or shrink the cancer, as well as to prevent the cancer from coming back. Please see the surgery, chemotherapy and radiation sections for additional information.
