1.What Is Cancer? CANCER‚ a 6 letter word that makes our world upside down. Cancer is not just one disease‚ but a large group of almost 100 diseases. Its two main characteristics are uncontrolled growth of the cells in the human body and the ability of these cells to migrate from the original site and spread to distant sites. If the spread is not controlled‚ cancer can result in death. 2.How does cancer occur? The body is made up of trillions of living cells. These cells grow‚ divide‚ and die in

It ’s so deadly because during the early stages‚ when the tumor would be most treatable‚ there are usually no symptoms. It tends to be discovered at advanced stages when abdominal pain or jaundice may result. Presently‚ there are no general screening tools. (American Cancer Society‚ 2013) Rates of pancreatic cancer

Benign Growth Patterns Hypertrophy – increase in cell size Hyperplasia – increase in cell number Metaplasia – conversion of one cell type to another Dysplasia – abnormal changes in size‚ shape or organization of cells Characteristics Altered cell differentiation Appearance changes Altered metabolism Tumor-specific antigens HCG – trophoblastic tumors Calcitonin

normal and abnormal biological processes‚ including evolution‚ development of the immune system‚ and cancer. There are two main types of genes that play a role in cancer‚ ocnogenes and tumor suppressor genes. An important difference between the two is that ocnogenes result from the activation of proto-ocnogenes‚ but tumor suppressor genes cause cancer when they are inactivated. Ocnogenes are mutations of certain normal genes called pro to-ocnogenes. Proto-ocnogenes

REDISCOVERING BIOLOGY Cell Biology and Cancer “ We now understand a lot about cancer. We know that it results from a series of genetic changes having to do with cell division and growth control and genetic instability‚ mortality‚ the suicide mechanism in cells; the ability of the cells to migrate; the ability of the cells to attract to them a blood supply. And so that’s pretty profound that in a few sentences one can summarize a sophisticated‚ fundamental understanding of what a cancer is.” LELAND

Dubes Syndrome. Birt Hogg Dubes Syndrome is a rare disorder that effects the skin and lungs and increases the risk of some types of tumors. These tumors are painful and very difficult and almost impossible to get rid of. The main cause of this disorder is inheritance of a dominant gene pattern resulting in a gene mutation. The symptoms of this disorder are bumpy like tumors on your skin and lungs. Some tests to diagnose this disorder include seeing bumps on skin or lungs‚ measurements of the pressure

pollution cause lethal tumors on sea turtles”. The lethal tumors have been most prevalent in Hawaii’s Green Sea Turtle Species. The tumors are linked to the invasive algae‚ “Superweed”. The algae grow along an area‚ where nutrient pollution is not managed regularly. When the sea turtles consume the invasive algae‚ the amino acids from the algae stimulate a virus that causes the tumors. Scientists have been trying to understand the pathology of these tumors. The tumors were most commonly located

-Malignant neoplasms of the lung: a) Primary lung tumors: Lung cancers are divided into two categories based on predominant cell type: - Non-small cell lung carcinomas (NSCLC): There are three common types of non small cell lung cancer. These are grouped together because they behave in a similar way and respond to treatment in a different way to small cell lung cancer.(58‚ 59) i) Adenocarcinoma: Now the most frequent primary lung cancer. It is usually the type of lung cancer found in non-smokers
