Radioisotopes are not only limited to imaging processes. Another use is to treat diseased organs or tumors by “killing cancerous cells” (Ioffe). This process is called radiation therapy. Some examples of the radioisotopes in this process are “Iodine-131‚ phosphorus-32” and for “more radical uses‚ Boron-10 to specifically attack tumor cells” (Ioffe). In the process‚ radioactive elements are inserted near the tumor. Radiation is more harmful to growing cells and cancerous cells grow at an uncontrolled rate

CELL BIOLOGY ESSAY -- PATHOGENESIS OF CERVICAL CANCER Introduction According to the Centre for Health Protection of the Department of Health (2011)‚ cervical cancer becomes the tenth commonest cancer in Hong Kong in 2008. Cervical cancer usually arises from sexual activity and human papillomavirus (HPV) (Bellentir‚ 2002). In this essay‚ Human papillomavirus would be further discussed. For example‚ the signal transport pathway of HPV 16 and HPV 18‚ which many scientists believe that they are closely

history of cancer. However‚ having a risk factor or not does not determine whether the child will contract the disease or not. In simpler terms‚ it can happen to anyone. Another way to describe rhabdomyosarcoma‚ or RMS‚ is that it is a malignant tumor in which cancer cells form in muscle tissue. Rhabdomyosarcoma comes from the Greek word Rhabdo‚ which means rod shape‚ and myo‚ which means muscle. Rhabdomyosarcoma usually forms as an expanding mass. It’s symptoms including but not limited to: lump

which than forms a tumor. There are many symptoms from kidney cancer like blood in your urine‚ a lump on the side of your abdomen‚ a loss of appetite‚ a fever that lasts for weeks‚ and extreme fatigue with many more symptoms. Kidney cancer is diagnosed by blood tests or a biopsy. If a biopsy is not possible they do other tests like the Intravenous Pyelogram in which a doctor injects a dye that highlights the Kidney urethra and bladder when an x-ray is taken that highlights any tumors. There is a

cells mutate and commence to grow and divide more expeditiously than mundane cells. Rather than dying‚ these anomalous cells clump together to compose tumors. If these tumors are cancerous (withal called malignant tumors)‚ they can invade and kill your body’s salubrious tissues. From these tumors‚ cancer cells can metastasize contrast‚ noncancerous tumors do not spread to other components of the body. One type of cancer‚ also the deadliest is Lung Cancer. Lung Cancer is the uncontrolled magnification

Another consequence is the cancer spreading to other organs. A tumor consists of a mass of cancer cells in the tissue. Usually an evasive tumor is malignant‚ causing cells to develop in the blood. Tumors invade growth that the tissue and organs need to survive. Interphase Prophase Metaphase Anaphase Telophase

Prostate cancer spreads when abnormal cells break away from the prostate tumor‚ travel through blood or lymph vessels‚ and attach themselves to other tissues to grow new tumors. These new tumors are made up

a good use of radiation because it kills the cancer cells and may even cure the cancer. It doesn’t always cure it but it will slow the process down. One reason radiation therapy is used‚ is to destroy the cancer cells. It is also for shrinking tumors. Tumors are mostly cured by the radiation. It can also just get rid of certain cancer symptoms. These are the things that radiation can cure. It destroys the cancer cells by attacking the genes. Genes are how cells grow and divide. When the radiation

neck cancers begin in the cells that make up the moist tissues (mucosal surfaces) of the mouth‚ nose and throat. Like other cancers‚ these cancers occur when abnormal cells begin to grow and divide uncontrollably and form a mass‚ called a malignant tumor. Doctors identify oral‚ head and neck cancers by the area in which the cancer begins: Lip and oral cavity cancer occurs on the lips‚ the front two-thirds of the tongue‚ the gums‚ the lining of the cheeks and lips‚ the floor of the mouth under

WAGR Syndrome WAGR (Wilms’ tumor‚ Aniridia‚ Genitourinary abnormalities‚ and mental Retardation) Syndrome is a contiguous gene deletion syndrome that is caused by a deletion in chromosome 11. The acronym for the syndrome comes from the various symptoms that are caused by the deletion – wilms’ tumor‚ aniridia‚ genitourinary abnormalities‚ and mental retardation. Wilms’ tumor is a tumor that is found in the kidneys that causes nephroblastoma‚ cancer of the kidneys. Aniridia‚ the absence of the iris
