What is Cancer - 1249 Words

The word Cancer means a group of diseases that are characterized by unrestrained cellular development. It It refers to cellular intrusion into neighboring tis-sues and may turn into metastasise if not treated at early stage. The most widely diagnosed malignancy in males is prostate cancer. Peripheral zone of the gland is the place where prostate cancers are generally found. It constitutes a dense arrangement of cancerous epithelial cells commonly in small form, penetrating glands with a symmetrical de-crease in stromal volume [2]. B. Lee et al. [3] used tissue bio-impedance to differentiate between the diseases because morphological differences between normal and malignant prostate tissue are present and sensitivity of electrical im-pedance spectra to cellular structure was known. Bio-impedance is one of the properties referred to a tissue’s re-sistance when electrical current flows in the tissue. It also means the ability of tissue to store electrical charges. Bio-impedance n ormally depends on spacing of cells, cellular density and size, and the components of the extracellular ma-trix (ECM). Differences between the malignant and benign tissue impedance of can be a distinguishing criteria for pathological procedures for cancer detection [1]. Actually, it was shown by Skourou et al. [4] that when there is tumor, the tissue impedance may be more sensible than conventional imaging techniques, such as computed tomography (CT) and ultrasound imaging.

This disease has been a mystery, until recent discoveries have begun to unravel its origins, treatments, and causes. Cancer is important to understand because it’s vast impact on the world today. There are ways to lower the chances of getting cancer as well as removing it. Anyone is capable of getting cancer but the three main facto rs that can cause it is genetic traits, life choices, and environmental surroundingsRead MoreWhat Are Cervical Cancer?2935 Words   |  12 Pages Abstract (TBD) Background: What is Cervical Cancer? This year alone approximately 12,360 documented new cases of cervical cancer in the United States and 4,020 deaths according to National Cancer Institute (â€Å"Cervical Cancer†, 2014). Cervical cancer is a slow growing cancer that grows in the tissues of the cervix (an organ that connects the uterus and vagina). The disease is predominantly caused by the human papillomavirus infection (HPV).

What is the Cause of it?1328 Words   |  6 PagesWhat is Breast Cancer? What is the Cause of it? Breast cancer is cancer cells that develop in the breast of a woman. The most common type of breast cancer is ductal carcinoma in situ. The cancer cells develop in the milk ducts of the breast. Doctors and researchers do not exactly know the cause of cancer. All they know is that it usually occurs when a cell’s DNA is damaged. When cells in the breast start to develop abnormally they begin to develop quicker than the normal cells. They also keep multiplyingRead MoreWhat Is Breast Cancer?937 Words   |  4 PagesBreast cancer is one of the most common cancers and the second leading cause of cancer-related death among women in the United States. Up to 6% of breast cancers are advanced or metastatic at the time of diagnosis, requiring chemotherapy1, 2. Aberrant, accelerated growth is a hallmark of cancer3, including breast cancer. The rapid expansion of treatments targeted to aberrant cell growth – for example, cell cycle targeted chemotherapies for the treatment of met astatic breast cancer – allows for preciseRead MoreWhat Is Atherosclerosis And Cancer?732 Words   |  3 PagesThis paper indicates a mechanism to target disease sites in diseases such as atherosclerosis and cancer, which are sources of TNFa. If a cell is engineered to seek TNFa sources like those in cancer and atherosclerosis, they could be utilized as a targeted therapy. In order to accomplish this a system of engineered proteins was utilized TNFa chimeric receptor (namedTNFR1chi), a previously engineered Ca2+-activated RhoA (named CaRQ), vesicular stomatitis virus glycoprotein G (VSVG), and thymidine kinaseRead MoreLung Cancer : What Causes It?1420 Words   |  6 PagesLung cancer is any type of cancer that begins in the lungs, although it is still considered lung cancer after it spreads to other parts of the body. Lung cancer is one of the most common cancers in the U.S. and worldwide. Forty percent of people will be diagnosed with lung cancer within their life span. Lung cancer, as with all cancers, is very complex, so the best way to comprehend it is to break it down into easily analyzed topics.

Ovarian cancer is the abnormal growth of malignant cells in the ovaries, the egg (ovum) producing part of the female reproductive system. Often, Ovarian cancer goes undetected until it has metastasized (spread) to the pelvis and abdomen. At this late stage, this cancer is difficult to treat. Ovarian Cancer ranks as the 11th most common cancer among women, and it is the 5th leading cause of cancer-related death for women.
