Introduction: Our environment plays a major role in contributing to the causes of the cancer disease. Taking a closer look at skin cancer for instance‚ we see how much of the effects of the sun’s dangerous UV rays can harm our bodies. What constitutes an environmental cause of cancer? When we talk about environmental causes of cancer‚ we are referring to the effects of environmental exposures or conditions that have direct or indirect effect on the origin or formation of the cancer disease in

Malignant astrocytomas or Gliomas are the most frequent form of primary cancer that arise in the brain. The most malignant and aggressive type of glioma is glioblastoma multiforme(GBM). GBM ‚which called grade IV astrocytoma‚ is one of the most common and deadly primary malignant brain tumor in adults with a high degree of morbidity and mortality and accounts for about 15% of all intracranial tumors in adults ages 40–75(2‚ 3) Incidence rates of glioma in The United States yearly is about 5 in 100

Faith Lowe Period 6 Can Cancer Tumors be starved to death? For scientists to even think about answering the question‚ Can Cancer Tumors be starved to death? They have to first find out what tumors need to grow‚ what can kill a tumor‚ and what happens when a tumor is a solid. For a tumor to grow it must obtain from the body’s blood supply all the food and nutrients it needs to make more cancer cells. If a tumor doesn’t get the food and nutrients the it won’t grow. To get these foods and nutrients

Alternative cancer therapies are an emotive subject. In this Summative assessment the main events in a hypothetical case history are recounted from a naturopathic point of view and an effective management plan for the final part of the nutritional treatment is described. To support the given treatment strategy an attempt is made to subjectively consider a critique of nutritional therapies in general and the Gerson cancer therapy in particular‚ written by Saul Green PhD‚ biochemist and science editor

Immune system: function and importance in cancer Causes and risk factors of cervical cancer The term "cancer" refers to a large group of very different diseases. They have one thing in common: the uncontrolled division of cells of an organ or tissue. These cells do not grow old and die not from spite of many changes in how healthy cells. They disguise themselves so the immune system does not recognize

Abstract Tamoxifen‚ most commonly sold under the brand name Nolvadex‚ is the most widely used drug in the treatment of breast cancer during both early and late stages. It belongs to a class of drugs known as SERMs (Selective Estrogen Receptor Modulators). SERMs work by blocking the estrogen receptors in breast cells to prevent any binding with estrogen. It is consumed orally as a tablet or as a liquid (Anon.‚ 2017). The following paper discusses the discovery of Tamoxifen‚ its laboratory synthesis

Quinazolines are the class of chemical compounds that are pharmacologically important as therapeutic agents. They are utilized as drugs and employed in cancer chemotherapy. They act by various mechanisms. Some of them act by inhibiting antifolat thymidylate syntheses‚ while some other derivatives inhibit tubulin polymerization. They were also found to inhibit the epidermal growth factor receptor (EGFR) tyrosine kinase over expression through the inhibition of autophosphorylation of EGFR. Further

The complexity of the tumor growth process involves many different phenomena. There are two main phases in this process; avascular and vascular. Tumor cells need oxygen and nutrients for proliferation‚ in the first phase‚ these supplements are provided by diffusion through the surrounding tissue. This is sufficient till the tumor size reaches to 2-3 millimeters and cells will need more supply. In this stage‚ the cells in the center of the tumor are exposed to the lack of oxygen and nutrients and

- Intraductal papillomas Intraductal papillomas are benign breast lesions usually affecting the lactiferous ducts‚ but smaller peripheral ducts may also be involved. They’re wart-like growths of gland tissue along with fibrous tissue and blood vessels (called fibrovascular tissue). The larger lesions may present with intramural fragile masses but smaller ones may be evident only on microscopic examination. Papillomas may be solitary or multiple.‚The distinction is important as the multiple form

Acromegaly is a disease in which some parts of the body grow out of proportion to the rest of the body. It commonly affects the nose‚ ears‚ jaw‚ fingers‚ and toes. Acromegaly can lead to a number of conditions over time‚ including: Diabetes. Arthritis. Heart disease. Sleep apnea. High blood pressure (hypertension). CAUSES The most common cause of acromegaly is an overproduction of growth hormone by the pituitary gland. This can result from: A noncancerous (benign)
