What does Radiotherapy and Chemotherapy in bone cancer involve?


Chemotherapy:A form of treatment where powerful drugs are injected into the body while these drugs are toxic to living tissue, they are more toxic to cancer cells than normal cells.hence they kill cancer cells in much larger numbers as compared to normal cells



Radiotherapy :Another form of cancer treatment where gamma rays are used to kill cancer cells and shrink tumors.Radiation therapy injuries or destroys cells in the area being treated.Although radiation damages both cancer cells and normal cells,most normal cells can recover form the effects of radiation and function properly


Why early diagnosis important in bone cancer?

There is no known cause for bone cancer and therefore there is no preventive precaution that can be followed.it can affect anybody. And so early detection and correct diagnosis assume higher significance

At what age bone cancer affect most

Bone cancer can affect people at any age
Bone cancer can affect peple at any age.primary bone cancer,excepting multiple myeloma and chondrosarcoma is more common in the first two decades of life whereas secondary bone cancer and multiple mylema is more common after the age of 45yrs. soft tissue sarcomas can occur at any age.

General Symptoms of Bone Cancer

The most common symptom of bone tumors is pain ,which is usually mild initially and becomes more intense gradually,But the most common symptom is with MFH or Fibrosarcoma is the presence of a mass or lump either on the bone or in the tissues surrounding the bone, This can be with other bone tumors too.Weakening of bones,numbness,tingling in the extremities... are other symptoms.while fever,chills,night sweats and weight loss can occur,they are more common after spread of the tumor to the tissues in the body

Bone cancer


What is

Bone Cancer ?


Bone Cancer is a rare cancer that forms in the cells of bones.Soft tissue cancers are the tumors arising from the tissue around the bone namely muscles,neurovascular structures,fat,skin,synovium etc.

What is the most common form of bone cancer?
The majority of cancer involving the bones is metastatic disease from other remote cancers.Primary bone cancer is much rarer

How bone cancer is generally caused?
In majority of the bone cancer affected, the cancer has actually spread from elsewhere in the body to the bones.Very rarely is someone effected by true bone cancer i.e. a cancer that begins from cells that make up the bone And so in almost all cases, it becomes important to determine if the cancer in the bone is because of transportation from other place or within the bone cells.



 Types of Bone Cancer:
       
          a. Primary bone caner:
          b. Secondary bone cancer:

a.Primary Bone cancer:


Here, the cancer begins in the tissue of the bone itself

 
 
 
 

The common types of primary bone and soft tissue cancers are:

                                                                1.Multiple myeloma
                                                                2.Osteosarcoma
                                                                3.Chondrosarcoma
                                                                4.Ewing's sarcoma.

b.Secondary bone cancer:


This cancer also referred as bone metastasis or skeletal metastasis. This is a form of cancer of the bone where the cancer has spread to the bone form some other organ. The most common cancers which spread to the bone are from the

                                                              1.Breast
                                                              2.Prostate
                                                              3.Lungs
                                                              4.Kidneys
                                                              5.Thyroid

Secondary bone cancer

Secondary bone cancer is a far more common than primary bone cancer.
