Osteosarcoma Signs and Symptoms

What Are The Symptoms Of Osteosarcoma?

Osteosarcoma or osteogenic sarcoma (also known as OS or osteo) is an aggressive malignant primary bone cancer. When OS metastasizes (spreads) it is often to the lungs but metastases to other bones may occur. It often begins near the ends of leg or arm bones near joints. Osteosarcoma is rarer in other bones like the pelvis, shoulder, and jaw but unusual sites are increasingly seen in older adults. Given its rarity and time of usual diagnosis, it is common to be misdiagnosed as a benign tumor or dismissed as growing pains. Understanding the signs and symptoms of Osteosarcoma can help identify the signs and catch it faster.

Who Gets Osteosarcoma?

With about 800+ cases a year diagnosed in the United States, OS is the most prevalent bone cancer affecting children and adolescent/young adults. Osteosarcoma can occur at any age but the most common age for diagnosis is in children and young adults during growth spurt times. There are a few known risk factors such as:

  • Age: risk is highest between 10 and 30 especially during growth spurt years, which indicates it may be related to rapid bone growth 
  • Height: usually tall for age which suggests it may be related to rapid bone growth 
  • Gender and race/ethnicity: more common in males and in African Americans and Hispanic/Latino people 
  • Paget disease of the bone: mostly affects people older than 50 
  • Hereditary multiple osteochondromas: benign bone tumors 
  • Inherited cancer syndromes:
  • Hereditary Retinoblastoma: rare eye cancer which has a mutation in the RB1 gene 
  •  Li-Fraumeni Syndrome: usually caused by abnormal changes in the TP53 gene 
  •  Bloom syndrome, Werner Syndrome and Diamond-Blackfan Anemia, etc.

There are no known environmental risk factors. You didn’t do anything to cause this cancer. 

Jen from Tasmania suggests, “Always question the doctors. If you aren’t satisfied with their answers you have the right to a second opinion. If you think you aren’t being listened to, go higher. Don’t give up until you get a definitive answer which suits the symptoms. Insist on the scans!”

Symptoms Of Osteosarcoma

There are several different common signs of osteosarcoma. If you are noticing these signs, communicate with your doctor to understand more steps. 

  • Growth spurts
  • Pain in bones
  • Lumps under the skin
  • Pain when moving affected limbs
  • Fevers
  • Broken bones 
Linda from Pennsylvania suggests, “Trust your instincts about your doctors. If you feel a strong connection and a lot of confidence in your doctor, then go with it. If you do not feel confident or feel something is off, go with that as well and look for a doctor you trust and feel confident in. We felt a very strong connection with the surgeon who diagnosed our son and a level of confidence that helped us to have a positive outlook.”

Coping With Osteosarcoma Diagnosis

Unlike a common cold or flu where you work with your family doctor for all aspects of treatment, a diagnosis of osteosarcoma comes with setting up an entire team to provide the care and treatment needed. Focus on allowing your personal team to be there for you. some will be absent but many more will show up when you didn’t expect them to be there. It is important to let those who are there for your family to offer and do what they can. Family and friends are often struggling to understand what is happening. Allow people to offer support in the way they are able to - it’s therapeutic for them too.

B’s Mom says, “Act quickly. Keep a positive attitude for your child. There are NO dumb questions, stay informed on your level of understanding. If you don’t understand or know... ASK! Guessing is worse than knowing.”

Resources To Help Cope With Osteosarcoma
