Bone cancer is considered as a rare cancer that develops in a bone. This cancer can start in any bone in the body and mostly long bones are affected that make up the legs and arms. Many bone tumors are benign that means they are non-cancerous and does not spread to any part of the body. Normal bone tissue is destroyed by this cancer and can spread to different body parts (known as metastasis).
Primary Bone Sarcoma: This tumor first develops in the bone. There is no exact cause of bone sarcoma but heredity can be considered as one of the causes. Bone cancer can be categorized into different types that include –
This type is most commonly seen in those people who are in between the age of 40-70. This cancer starts in cartilage cells and its common sites include leg, shoulder, hip, arm and pelvis.
This type is most commonly seen in young people who are in between the age of 5-20. The most common sites of this cancer include the upper arm, ribs, leg and pelvis.
This type is most common in the upper arm and knee and it starts from the bone cells. Osteosarcoma is usually seen in young adults and teens.
The most common types of benign tumors include –
This type appears in the bones of the feet and hand. This usually involves no symptoms and is also considered as the most common type of hand tumor.
Giant Cell Tumor:
This tumor is a benign tumor that affects the leg.
This is a single tumor that takes place in the feet and the hand. This is usually seen in young adults.
This is considered as the most benign bone tumor and is mostly people who are under 20 years of age are afflicted with it.
This usually occurs in the long bones that is seen commonly in those people who are in their early 20s.
Metastatic cancer is the cancer that spreads to the bones from elsewhere in the body. Metastatic cancer spreads to a bone but it is still not known as bone cancer as the tumor cells are from the primary cancer.
The cancers that spread to the bone are –
The causes of bone cancer are unknown. The patients, who are suffering from chronic inflammatory diseases such as Paget’s disease, have more chances of developing a bone cancer. The bone cancer starts due to an error in the DNA of a cell. This error tells a cell to divide and grow in an abnormal way. The cells then go on multiplying instead of dying at a given time. The build-up of these mutated cells creates a tumor that can affect surrounding structures or can also spread to different body areas.
Stage 1 :
At this initial stage, the cancer is limited to bone and has not spread to any other part of the body. The cancer at this stage is also considered as low grade. This stage can be further categorized into –
In the second stage, the cancer is considered as high grade and has not spread to any part of the body beyond the bone. This stage can be further categorized into –
At this final stage, the cancer could be of any grade and has spread to different body parts including the lungs.
A number of imaging tests are performed in evaluating the area of concern that include –
Different biopsy procedures are used for diagnosing bone cancer such as –
Bone cancer can be treated with the help of different treatment options that include –
This treatment makes use of certain chemicals for destroying cancer cells. This is usually given through a vein that travels in the entire body. Radiation therapy is often combined with chemotherapy for shrinking the cancer to a manageable size so as to enable a surgeon to carry out a limb-sparing surgery. This therapy is used in those people who have bone cancer that has spread to different body parts.
A surgery entirely removes the bone cancer. There are different types of surgery for treating bone cancer such as –
Radiation Therapy :
High-powered beams of energy are used in this therapy for destroying cancer cells. The high-powered beams of energy are targeted at precise points in the body. This therapy is meant for those people who are suffering from bone cancer that cannot be removed with the help of surgery. The radiation therapy may control symptoms and signs that include pain in those people who have advanced bone cancer.
