Radiation therapy uses high-energy radiation to shrink tumors and kill cancer cells. X-rays‚ gamma rays‚ and charged particles are types of radiation used for cancer treatment. The radiation may be delivered by a machine outside the body called a linear accelerator to focus x-rays directly on the tumor or tumor bed (external-beam radiation therapy)‚ or it may come from radioactive material placed in the body near cancer cells (internal radiation therapy‚ also called brachytherapy).

such as chemoembolization. With the introduction of chemoembolization for the treatment of‚ primarily‚ liver tumors‚ a question emerges; which radiologic modality is better: chemoembolization or traditional radiation therapy? While both chemoembolization and traditional radiation therapy have their benefits and obstacles‚ will chemoembolization be more effective at treating liver cancer? Interventional Radiology (IR) first came about with the introduction of the first angiography preformed in

Case Study of Management Information System “When Radiation Therapy Kills” (Ethical and Societal Issues in Information System) Background of the case: When the new radiation therapies are raised‚ they’ve promised to cure people from illness. Contemporary radiation therapy offers a good example of society failing to anticipate and control the negative impacts of a technology powerful enough to kill people. Advanced technologies in radiation treatment represent hope and a chance to live and survive

Vitamins vs. chemotherapy and radiation for cancer therapy We have a general understanding of cancer--one-third of cancer patients die in five years. (1) With present therapies‚ only slow annual improvement is expected. Vitamins have been extensively demonstrated in clinic trials.

There are 2 types of radiation therapy. The first‚ external beam radiotherapy‚ delivers radiation to the prostate from outside the body. The second‚ prostate brachytherapy or internal radiation therapy‚ is done by placing grain-sized radioactive materials in the prostate via needles or catheter. 4. Hormone Therapy Hormone

This type of therapy is efficient in destroying the cancer‚ but because the rays aren’t accurate and continue moving through the body until they exit‚ some of them are absorbed into surrounding healthy tissue. The most common areas of the body that are damaged by this type of radiation therapy is the bladder and other surrounding organs (Proton Therapy). Radiation itself is a known cause of cancer and this risk may outweigh the benefits
