Bone cancer is a type of cancer that attacks bones. This disease can be diidap by children to adults.
Bone cancer is divided into two, namely primary and secondary bone cancer. Named primary bone cancer when the cancer occurs and develops directly inside the bone. While secondary bone cancer is a cancer that comes from other body parts that spread to the bones.
The entire bone in the body can be attacked by this disease, but mostly occurs in the bones of the legs and arms.
Here are three main signs and symptoms of bone cancer, namely:
- Pain. A person with bone cancer will feel pain in the area of ??bone that is attacked, and the pain will increase as you move. Pain will usually be felt continuously until the night.
- Swelling. The area around the bone affected by cancer will experience swelling and reddish color. If swelling occurs in the bone close to the joint, then the movement will become difficult and limited.
- Brittle bones. Bone cancer causes bones to become weak or fragile. Even if it is severe, a mild fall or a small injury alone can make the bone broken.
In addition, there are also some other symptoms, such as numbness and numbness when cancer in the spine suppresses innervation, bumps appear on the bones, the body feels tired, weight loss, fever above 38 ? C, and sweating especially at night .
In adults, symptoms of bone pain are sometimes mistaken for arthritis. In children and adolescents, it is sometimes misinterpreted as a side effect of bone growth. Should see a doctor if you or your child continues to feel pain in the bone or the pain gradually worsens.
Causes of bone cancer
The exact cause of bone cancer is unknown, but this condition is thought to be caused by changes or mutations within the DNA structure of cell growth controls that keep it growing out of control. The buildup of these cells then form a tumor that can attack nearby bone structures or even spread to other body parts.
Here are some factors that may increase a person's risk of developing bone cancer.
- Exposure to high radiation from a treatment ever experienced by patients, such as radiotherapy.
- Have had a history of a type of eye cancer called retinoblastoma as a child.
- Suffered from Li-Fraumeni syndrome, a rare genetic condition.
- Suffer from Paget's disease, a condition that can cause weakening of bone.
- Suffer from umbilitic hernia disease from birth.
The types of bone cancer
Based on where the cancer cells begin, bone cancer is divided into:
- Osteosarcoma. This bone cancer develops at the end of long bones in the bones that are actively growing. This type usually attacks the shins, thighs, and arms. Osteosarcoma can be afflicted by anyone, but the most common are young adolescents and adolescents who are new in adulthood, ie, the range of 10-19 years.
- Chondrosarcoma. This bone cancer develops in the cartilage cells that normally attack the femur, hip bone, ribs, shoulder blades, or upper arm bone. Chondrosarcoma commonly diidap by people aged over 40 years.
- Ewing's sarcoma. This bone cancer develops in the immature nervous tissue of the bone marrow. This type usually attacks the femur, shins, and pelvis. Ewing's sarcoma is more common among boys than adults, at the age of 4-15 years.
