with the BRCA mutation. The results illustrated that genetics were not the sole factor in ER-negative tumors in African women and that social factors were at play (Huo 2009). Recent research has shown the effects of environmental stress on breast cancer. When rats are socially isolated early in life‚ increasing stress and vigilance and prompting immune system changes‚ they develop breast tumors 40% earlier and four times more often than do rats housed in groups. The isolated rats also displayed larger

My project is about lung cancer‚ which falls under the science branch of oncology. Lung cancer is the uncontrolled growth of abnormal cells in the lung. The uncontrolled reproduction of cells results in the formation of tumors that can block or compress airways and displace or damage normal lung tissue. This can make the lung stop functioning as it should. Most lung cancers start in the lining of the bronchi‚ or in glands below the lining of the bronchi‚ frequently in the periphery of the lungs.

It causes extreme fatigue and nausea. Early effects begin as lumps and masses in the breast. These tumors can be painful and can even cause changes to the breast surface. It also commonly metastasizes‚ or spreads‚ to other tissues in the lungs‚ bones‚ and liver‚ as was the case with my Grandma. There are many causes of Breast Cancer‚ but the most common

cost of either of the 2 FDA-approved FISH assays (just reagents) is almost $100‚ with considerable cost added by the need to purchase a fluorescence microscope and filters. It also may be difficult to visualize the morphologic features of the tumor cells and to separate in situ from invasive carcinoma when evaluating the amplification product with fluorescence. In addition‚ fluorescence fades quickly and‚ therefore‚ is not a permanent record. Chromogenic in situ hybridization (CISH) seems

PM-DTPA/PTX was developed to passively target solid tumors‚ however‚ instability of micellar carriers in an aqueous medium are often reported problems. Thus lyophilization is a potential alternative to prevent instability in these cases[23‚24‚30]. Given that freeze-dried kits for radiodiagnosis are reported as an easy‚ fast‚ safe and reproducible way to obtain radiopharmaceuticals‚ it has been seen as a safe and effective alternative to prepare the PM-DTPA/PTX formulation[22‚31‚32]. However‚ considering

cells grow‚ divide‚ and stay alive are called oncogenes. Others that slow down cell division‚ or cause cells to die at the right time‚ are called tumor suppressor genes” (The American Cancer Society medical and editorial content team‚ 2016). Sometimes cells incorrectly copy the DNA during mitosis causing there to be irregularities in the oncogenes and/or tumor suppressor genes which then triggers the sudden death and/or reproduction of

Lung cancer is a cancer that starts off or eventually grows into the lungs. The cancer is formed when the lung cells don’t function properly and start rapidly reproducing and then forming tumors. There are three main types of lung cancer: non-small cell lung cancer‚ small cell lung cancer‚ and a lung carcinoid tumor. Non-small cell lung cancer is the main type of lung cancer‚ affecting around 85% of people with lung cancer. Small cell lung cancer

Occasionally tumors develop on the brain or spinal cord. Half of the people with NF1 also inhibit learning disabilities. The less common disorder‚ NF2‚ characterizes itself by multiple tumors on cranial and spinal nerves. Hearing loss will nearly inevitably occur in the early teens for people with NF2.

of cancer are treatable‚ and some are not. Cancer usually comes from the development of a tumor. Tumors form in the body when cells are produced without cause. New cells are formed when they are not needed‚ and they group together to form a tumor. The tumor can be benign‚ which means that it is non-cancerous‚ or it can be malignant‚ which means that it is cancerous. If cells break away from a malignant tumor‚ they will enter the bloodstream‚ and spread throughout the body‚ hurting other parts of the
