Radiotherapy or Radiation therapy is the old way for treating various types of cancers and thousands of cancer patients are treated today with radiation therapy. Radiation therapy means using rays of high-energy to kill cancerous cells and reduce tumors. Radiation therapy can be used alone or it can be combined with other treatments like chemotherapy or surgery. A patient may be given more than one kind of radiation therapy. It is often used to shrink the tumors prior to surgery or it can be given post surgery to stop the cancer from returning. Radiation therapy may be administered with chemotherapy. It helps in shrinkage of the tumor and makes the chemotherapy drugs perform better, if given before or during chemotherapy. It can be given after chemotherapy which can help to destroy remaining cells of cancer.
The Malignant Mesothelioma location sometimes can make it difficult to use high radiation doses without doing major damages to the nearby organs and so there are doubts if radiation is working in treating Malignant Mesothelioma cancer. But it is really effective when used for killing remaining cells of cancer post surgery. It is effective also in controlling symptoms and so helps patients feel comfortable who are suffering from Malignant Mesothelioma cancer. Radiation therapy is effective in pain control and to control the fluids accumulation in the lungs or abdomen.
Radiation therapy uses a kind of energy known as ionizing radiation which is able to damage or destroy cells of cancer. It almost stops the cancerous cells growth by making it impossible for cells to divide and grow. It is given as a local treatment as it affects only the cells in treated area. Cells of cancer are not destroyed immediately when a patient is given radiation therapy. It will take many days of treatment until cancer affected cells will begin to die. But, they will continue to die for weeks or months after stopping the treatment. With latest technology the radiation rays are tightly focused. However, other cells that are non-cancerous nearby the body area of the treatment are likely to be destroyed also by radiation. Radiation therapy has lesser side effects than other treatments of cancer.
