Transcript of Bone Cancer

By Jackson & Austin BONE CANCER Osteosarcoma -
Most common primary malignant bone cancer.
Affects males between 10 and 25 years.
Can affect older adults.
It often occurs in the arms and legs and at areas of rapid growth around the knees and shoulders of children. Who and what is affected? Signs and symptoms Treatments available for Bone Cancer Causes Surgery - used to try and remove the entire tumor and a surrounding area of normal bone. After the tumor has been removed, it is examined to be determine if there is normal bone completely surrounding the tumor. Sometimes this method does not completely remove all of the cancer. If a portion of the cancer is left behind, it can continue to grow and spread, and requires further treatment. If the tumor has normal cells completely surrounding it, there is a better chance that the entire tumor has been removed and less chance for recurrence. Historically, amputations were sometimes used to remove bone cancer. Newer techniques have lowered the need for amputation. In many cases, the tumor can be removed with a rim of normal bone without the need for an amputation.

Chemotherapy - this is the use of various medications used to try to stop the growth of the cancer cells. Chemotherapy can be used prior to surgery to try to shrink the bone tumor to make surgery easier. It can also be used after surgery to try to kill any remaining cancer cells left following surgery.

Radiation therapy - uses high-energy X-ray aimed at the area of the cancer to try to kill the cancer cells. This treatment is given in small doses daily over a period of days to months. Radiation therapy can be used either before or after a potential surgery, depending on the specific type of cancer. SURGERY CHEMOTHERAPY RADIATION THERAPY

The exact cause of most bone cancers is unknown. However, scientists have found that bone cancers are associated with a number of other conditions. Still, most people with bone cancers do not have any known risk factors. Research is underway to learn more about the causes of these cancers.

The majority of bone cancers are not caused by inherited DNA mutations. They are the result of mutations acquired during the person's lifetime. These mutations may result from exposure to radiation or cancer-causing chemicals, but most often they occur for no apparent reason. These mutations are present only in the cancer cells and so cannot be passed on to the patient's children. How dangerous is this type of cancer? There is no single cause of bone cancer, but some factors increase the risk of developing it:

Previous treatment with radiation, especially at a young age
having Paget’s disease (a non-cancerous disease of the bone)
Having had osteochondroma or chondroma (non-cancerous bone tumours)
Having a genetic condition, such as Li-Fraumeni syndrome, retinoblastoma or Rothmund-Thompson syndrome
Previous treatment with chemotherapy, especially at a young age pain or tenderness in the area of the tumor
persistent ache that may feel worse at night
swelling or a lump
problem moving the affected joint
broken bone Lifestyle changes Ewing's sarcoma-
Most aggressive bone tumor.
Affects younger people between 4-15 years.
It is more common in males.
Very rare in people over 30 years of age.
It most commonly occurs in arms and legs. Chondrosarcoma -
Second most common bone tumor and accounts for about 25% of all malignant bone tumors.
These tumors arise from the cartilage cells and can either be very aggressive or relatively slow growing.
Unlike many other bone tumors, chondrosarcoma is most common in people over 40 years of age.
It is slightly more common in males and can potentially spread to the lungs and lymph nodes. Chondrosarcoma most commonly affects the bones of the pelvis and hips. A healthy lifestyle can positively affect lowering the chances of you getting all cancers. Some suggestions are too: Lower alcohol consumption, drink lots of fluid such as water and milk, eat lots of vegetables, have a variety of food groups and balanced diet.

Some top cancer fighting foods: asparagus, eggs, beans, blueberries, strawberries, leafy green vegetables, colorful vegetables, tomatoes, tea, grapes, lean meat such as fish and chicken.
Try to exercise if possible once everyday. Cancer of the skull This type of cancer is very aggressive with the risk of spreading to the lungs. The five-year survival rate is about 65%. Osteosarcoma Ewing's sarcoma The three-year survival rate is about 65%.Lower survival if spread to the lungs or other tissues. Chondrosarcoma The five-year survival for the aggressive form is about 30%, but the survival rate for slow-growing tumors is 90%. The overall 5-year relative bone cancer survival rate for 1995-2001 was 69.4 percent. This is the percentage of people who are alive 5 years after a bone cancer cancer diagnosis, whether they have few or no signs or symptoms of bone cancer, are free of disease, or are having treatment for bone cancer. Interesting Facts True bone cancer affects over 2,000 people in the United States each year. It is found most often in the bones of the arms and legs, but it can occur in any bone. Children and young people are more likely than adults to develop bone cancer. Stage 1 means that the cancer remains in the bone and has not spread to any other areas of the body, and an examination of a biopsy shows that it is not an aggressive type of bone cancer.
Stage 2 indicates that while it is still localized to the bone, a biopsy has found it to be an aggressive cancer, meaning it has the ability to grow and spread quickly.
Stage 3 bone cancer means it is in more than one area on the original bone.
Stage 4 refers to bone cancer that has spread from the bone into other parts of the body. Their are different stages of bone cancer: Weight loss and the ability to easily suffer bone fractures can happen with bone cancer.
