Here are some of the common symptoms:
One of the common symptoms of osteosarcoma is a pain. They occur mainly in the long bones of the body, like legs and arms. The pain cannot exist at first. The pain is caused by vigorous exercise or physical injury, which is common in young people affected by bone cancer. The cancer pain is stronger when the bone is used and at night.
Here are some of the symptoms:
– sensitivity, swelling, and pain;
– redness and heat in the affected area;
– sharp and sudden pains in a bone that have hurt for a while;
– Difficulty moving, lifting, etc.
50% of all osteosarcomas begin in the knee area. The symptoms are usually present for several months before a diagnosis is made.
Some people may feel a mass or a knot when the tumor is in a location that can be detected by touch. Sometimes the painful spot swells. Swelling and pain have different patterns, all depending on the type of cancer. The osteosarcoma occurs mainly in adolescents and children, in the thigh and upper arm area. Some people with bone cancer may develop a slack when the tumor is in the hipbone or leg.
3. Pathological fractures
As the disease grows, the bones become weaker. When a person who has bone cancer gets a split near the tumor, the person experiences severe bone pain that has been painful for a while. In many patients, osteosarcoma is diagnosed when they get a broken bone from a minor accident. The osteosarcoma makes the bone so weak that even a small accident can lead to breakage.
4. Systemic symptoms
Although it is bone cancer, sometimes the symptoms are not directly related to the bone. Some symptoms include fatigue, weight loss and difficulty breathing.
Less common symptoms
As the cancer progresses, new symptoms appear. Some of them are fever, drowsiness and fatigue, low red blood cell count and unintentional weight loss.
With bone cancer and the treatment, many complications are possible.
Some of the complications include:
– bleeding from the operation;
– Chemotherapy-related problems: hair loss, vomiting, nausea, diarrhea, minor bleeding and bruising, fatigue;
– Radiotherapy problems: weak bone growth, diarrhea, burns, hair loss, organ damage, new cancers;
– learning problems;
– lung and heart problems;
– problems with fertility;
– changes in sexual development;
– problems with growth.
Bone cancer spreads most often in the lungs. Osteosarcoma is widespread and affects the gastrointestinal tract and the central nervous system.
