Bone Metastasis Survival Rate

The Mechanics of Bone Metastasis Survival Rate

Bone metastasis is a form of cancer that occurs when cancer spreads from its original area to the bones. Any form of cancer can spread, however, certain types of cancer like breast cancer and prostate cancer have more of a tendency to spread to the bones. Continue reading to learn about bone metastasis survival rate.

Any bone in the body can be affected when cancer spreads but the spine, thighs, and pelvis area is the most common areas that cancer metastasizes to. Cancer makes bones weaker and may cause breakage as well as pain. In rare cases, cancer within in the bones can become so severe that it's untreatable.

However, for the most part, medication can be used to reduce the pain and other symptoms. Bone metastasis can occur as the first sign of cancer or after many years.

Fortunately, bone metastasis has a survival rate of 70% in both adults and children, five years after diagnosis; for adults alone, it's 80%.

Causes of bone metastasis

A large proportion of those that develop bone cancer have a hereditary predisposition. This has been a common finding. Aside from hereditary predisposition, there are other circumstances that can make a person more susceptible to developing bone metastasis, such as radiation, bone marrow transplants, and possibly injuries.

Exposure to large amounts of radiation can create a predisposition towards bone cancer. This has been proven. A simple x-ray will not create this kind of disposition, however, radiation in the form of therapy to treat cancer and other disorders can create a predisposition. This may be due to the build up of minerals in the bones as a result of the radiation therapy.

Radiation releases radioactive materials such as radium and strontium which increases the number of mineral deposits in the bones. Bone marrow stem cell transplants have been known to create a predisposition as well.

Even diseases like Paget's which is an abnormality in the bones, most common in people over 50, can create a predisposition to bone metastasis. Some even believe that injuries to bones can predispose a person to bone cancer, but this hasn't been proven.

Symptoms of bone metastasis

As with many disorders, bone metastasis is sometimes hard to detect because there aren't always symptoms. Furthermore, symptoms may appear as the first sign of bone metastasis or after many years of having cancer.

Doctors have not yet determined why cancer will spread to the bones and not other areas of the body.

However, when symptoms do surface they often include:

  • Bone pain
  • Broken bones
  • Bladder incontinence
  • Bowel incontinence
  • Weakness in the legs or arms
  • Hypercalcemia
  • Nausea
  • Vomiting
  • Constipation
  • Disorientation.

Survival Rate of bone metastasis

Bone metastasis survival rate: Fortunately, the survival rate for bone cancer is extremely high. Those diagnosed with bone cancer five years prior have a survival rate of 70%. This statistic includes both adults and children. Statistics that include adults only reveal a survival rate of 80%.

Keep in mind that there are people that live much longer than five years. The statistics represent the averages among bone cancer survivors. The results may vary depending on the individual prognosis of the patient.

Bone cancer is a disorder that often occurs as a result of cancer spreading from the site of origin to the bones. Doctors are still not aware of why cancer will spread to the bones as opposed to other areas of the body. This can happen in instances of any kind of cancer, however, it's more likely to happen in incidences of breast cancer and prostate cancer.

Furthermore, cancer can spread to any bone in the body but more often than not, tends to spread to the thighs, pelvis, and the spine. Often, symptoms don't surface until the cancer has progressed.

However, symptoms can surface early in this form of cancer or can surface many years after treatment. Bone cancer can have many unpredictable twists and turns when it comes to symptoms and which parts of the bones become affected by it.

However, once the cancer has become aggressive, the symptoms can be quite painful. Many people do survive this form of cancer, so, the bone metastasis survival rate is not a death sentence.
