Bone Cancer: Treatments and drugs

Posted on February 28, 2011 by admin

Different types of treatment can be chosen depending on several factors: stage of cancer, its type, age and health of the patient and his preferences. The usual treatment of the bones cancer include: radiation therapy, surgery, chemotherapy and a combination of these methods.

Bone cancer treatment: Sugery

During the surgical intervention the tumour can be removed. The stroked tissue is taken with the health tissue which is near it. The surgical intervention can be of several types:

  • Removing of a limb. Sometimes the big tumours or too aggressive cancer cells may be removed only with the whole limb or with the part of the limb. The procedure of amputation is not very popular now because of existing of more effective treatment. After amputation the artificial limb is fitted and patient has to learn how to deal with it and how to do the everyday tasks in easy way.
  • Removing of a bone. When cancer is located in a bone only, this bone can be removed careful. The free space can be filled with the bone from another part of the body or with the special prosthesis made from metal. The rehabilitative therapy is obligatory in any case.
  • Removing of a bone with some tissue. This method is used when cancer filled the bone and a tissue near it. After the removing operation, special metal prosthesis can be put in.

Bone cancer treatment: Radiation therapy

Radiation therapy is based on x-rays, which can kill the cancer cells. X-rays are made by a special machine.

Radiation therapy also can stop the increasing of a cancer cells. For this purpose it is usually used with chemotherapy.

Radiation therapy can also reduce the pain. Sometimes this method is used after surgery, to kill cancer cells which still stay in the body. Radiation therapy is the only way for people who are against amputation.

Bone cancer treatment: Chemotherapy

Chemotherapy is based on drugs which can kill the cancer’s cells. Almost all drugs of this type are given intravenously. Sometimes this method is used with radiation therapy before or after surgery. Chemotherapy is the best treatment when cancer cells are already spread in the body.

Tests which can determinate the stage of the cancer of bones.

Posted on February 28, 2011 by admin

This step is next after putting the diagnoses. The treatment is depending on the cancer’s stage.

The stage #1. In this stage the cancer is located only in the bone and cancer’s cells are not aggressive.
The stage #2. The cancer still stays in the bone, but cancer’s cells become aggressive.
The stage #3. The cancer is spread into several places of the same bone.

Tests and diagnosis

Posted on February 28, 2011 by admin

Imaging tests

These tests help to examine stroked area of the bone. Doctors usually propose more than one test from this list to make the view from different sides.

  • Scan of the bones
  • X-ray
  • Computerized tomography (CT)
  • Positron emission tomography (PET)
  • Magnetic resonance imaging (MRI)

Taking a part of tissue for testing in laboratory

This procedure is called the biopsy. A small part of tissue is taking from the tumour and sending to lab for analysis. The result of this testing can determinates a type of cancer and weather the tumour is of cancer origin or not. With the help of biopsy, the doctor can prognosticate the aggressiveness of the cancer cells.

The biopsy can be made in different ways:

  • With the help of a needle, which inserting into tumour through the skin. Only small pieces of tissue can be removed.
  • Surgery removing is making through the incision. This type of biopsy can be excisional or incisional.

The biopsy must be done very careful, with the future possibility to remove the full tumour.
