Electromagnetic radiation

radioactivity. Within this radiation lab experiment, we put the following hypothesis to the test: If the distance from the source, in centimeters, is increased then the Ionizing Radiation does is expected to decrease because the radiation decreases as it gets farther away from the radiation emitter, due to the loss of energy from the radioactive particles as they move through the air. The hypothesis stated above is accepted because of the overall decrease of radiation as the distance from the…

mesothelioma include surgery, radiation therapy and chemotherapy. In surgery a part of the abdominal tissue is cut out to remove the tumor. At times the doctor may also need to remove a lung or a portion of the diaphragm as per the requirement of the surgery. Radiation therapy, the second method, requires the application of high energy X-rays to shrink the tumor and kill the malignant cells. The rays may be applied from an external machine or by placing the radiation source directly to the…

There are four types of external-beam radiation therapy: Three-dimensional conformal radiation therapy (3D-CRT), Intensity modulated radiation therapy (IMRT), Proton beam therapy, and Stereotactic radiation therapy. 3D-CRT has special computers creating detailed 3D pictures of the cancer allowing the treatment team to target the beam more accurately. With this method, they are able to use higher doses of radiation while having reduced risk of healthy tissue damage. IMRT uses a Varian Clinac iX-S…

Prostate cancer is the second most common cancer among men, behind skin cancer. Although that is a startling fact, prostate cancer can often be successfully treated. To better understand how prostate cancer affects the male body, it is a good idea to know the body parts around it and how they work. The prostate is a gland that is only found in males, sitting below the bladder and in front of the rectum. The prostate gland makes some of the fluid that protects and nourishes the sperm cells in…

of protons. Radioactive decays also are a process which has an unstable atomic nucleus and which causes it to lose energy this because of radiation, for example there three main types of radioactive decay alpha, beta, and gamma particle. If a material has unstable nuclei it would be considered as radioactive. If an atom has emitted an alpha, or beta radiation it nucleus would change and become an nucleus of an different element. This would be because the number of protons in the nucleus would…

any individual, in any stage of life, in any part of the body. Despite the fact that almost 40% of people will be diagnosed with cancer at some point in their lives, cures and treatments are few and far between. Chemotherapy--in conjunction with radiation and surgery--is one of the leading treatments for all sorts of cancer. But this is a harsh _____, and it takes a physiological toll on the human body. In the early 19th century, German chemist Paul Ehrlich coined the term chemotherapy to…

INTRODUCTION: Cancer exists as a leading cause of death worldwide, treatments are available in a wide range but also side effects are harshly associated to it. Chemotherapy is most widely suited and recommended treatment of any cancer type. It is the conventional concept that chemotherapy drugs selectively killed damaged cells but novel generated facts explores that they also damages the normal cells also by the dependence of dosing. Hence, there exist fact to develop the approaches that…

In this procedure doctors can check the axillary lymph nodes that they are having cancer or not without actually removing them. Removing the axillary nodes in huge manner increases the risk of lymphedema so for reducing this kind of risk of lymphedema this SLNB is performed or done. in this procedure surgeon first finds and removes the lymph nodes in which there is high risk of developing a tumor this is performed by injecting a radioactive substance blue dye into the tumor to area around it or…

Cancer has affected many of people all around the world. There is so many types of cancer’s today that have affected many of different people. Cancer can happen to just about anyone. I will discuss and go over about what is Cancer and how it is treated. Cancer is caused by uncontrolled division of abnormal cells in different parts of the body. Cancer can progress slowly or fast it just depends on your body and the rate at which the abnormal cells or dividing. Cancer is one of the five major…

Relapsed/Refractory Follicular Lymphoma Response Evaluation By Liji Thomas, MD Relapsed or refractory follicular lymphoma (FL) is a condition that requires a careful selection of treatment options. It often occurs in older people, who may have significant comorbidities, or who may have more advanced grades or stages of the cancer. Various treatment schedules are thus used in relapsed or refractory lymphoma, which must be evaluated for evidence and amplitude of response. This may begin with…
