For a simple explanation, cancer is the class of diseases associated with cell, a group of cells that can not display its controlled growth (exceeding the normal limits), invasion (intrusion on and destruction of adjacent tissues), and sometimes metastasis (spread to other locations in the body via lymph or blood).
There are more than 100 different types of cancer, and each is classified by type of cell that was originally affected.Almost all types of cancer harm the body when the damaged cells to divide uncontrollably to form a lump or mass of tumor tissue (except in cases of leukemia where the cancer prohibit normal blood function with abnormal cell division in the bloodstream). Tumors can grow and interfere with the digestive system, nerves, and blood circulation, and they can release hormones that alter the function of the body. Tumors that stay in one place and shows limited growth of this type of cancer is generally considered benign.
Cancer cells would be extremely dangerous, or malignant, tumors formed when two things happen:
- Cancer cells to successfully move the entire body using blood or lymphatic system, destroying healthy tissue in a process called invasion
- Successful cells divide and grow, forming new blood vessels to feed themselves in a process called angiogenesis.
The abnormal growth establish in human bone are called Bone tumor, in medical it often called benign and malignant while probably public known it as bone cancer.
It is very difficult situation when you were diagnosed and suffering from bone cancer or some other form of cancer for that matter. It is only natural to ask many questions. So far, the exact causes of this disease are unknown. However, it is said that it was acceptable. If you are in a time in your life suffered from a fracture and a metal implant is placed in the body to repair the fracture, which can also expose you to bone cancer.
This disease usually affects teenagers and young adults. Cancer cells or the type of cancer is known as the abnormal cancer cells begin to develop. For example, if the cancer metastasizes to the lungs, the disease is not cancer. It remains metastasized bone cancer.
The known symptom of bone tumors is only pain, but many patients experience no symptoms, except for a painless mass. Some bone tumors may weaken the structure of bone, as pathological fractures. There are several types of bone cancer. Below are some of them:
- Sarcoma: This type of cancer arising form osteoid tissue found in bone. It is very common in the knee or the upper arm.
- Ewing's sarcoma: This is named after the surgeon who discovered. It is particularly among men. It affects the thigh bone, knee, thigh and pelvis.
