What is Cancer

  1. 1. Best Walter White Quote. 2011. Video. Youtube AMC Original Series, “Breaking Bad” “never give up control. live life on your own terms.”
  2. 2. Mutations in a cell’s DNA canbe caused by certain viruses,exposure to high levels ofenergy and chemical exposure.
  3. 3. Carcinogens are various substances,High levels of energy such as; energy forms and types of radiation that is directly connected the causeX rays, nuclear of cancer.radiation andrays from the sun cancause cancer mutations. An oncovirus is any virus that causes cancer. The name refers to the cell’s infected RNA or DNA. Sarah Leen. Skin Cancer Prevention. 2011. Photograph. National GeographicWeb. 6 Dec 2011.
  4. 4. Unrestrained cell growth and division that can lead to serious health problems.Phil Mayor, Slideshare.net, “What is Cancer?” Cancer cells are the result of DNA sequence mutations. These errors in cell DNA ruin a cell’s ability to control it’s own division cycle. A cancer cell can freely divide uncountable times.The ability of cancer cells to divide indefinitely is a result of cancer cellsrebuilding their telomeres after each cell division.
  5. 5. Cancer Cells are specifically different than normal cells in two ways1) The cell loses it’s “contact inhibition” Normally, cells divide until they bump up against other collections of cells. Cancer cells ignore the signal and continue to divide at a very high density. (formation of tumors)2) Cancer cells divide indefinitely A healthy human cell divides until it touches other cells or until the section of DNA found at the tip of a chromosome is to short to divide again. This section of DNA is called a telomere. A cancer cell will rebuild it’s telomeres each time that it divides. Cancer cells can divide forever if not fought with chemical treatment.
  6. 6. Phil Mayor, Slideshare.net, “What is Cancer?”The normal cell tissue is healthy because it isn’t over runwith dense clusters of cells.The Cancerous cell tissue is at a very high density leveldue to the cancer cell’s ignorance to contact inhibition.
  7. 7. Benign tumors are just an abundanceof normal cells that mass together.Typically, many moles on a person’sbody are benign masses of cells. Malignant tumors are the mass of cancer cells that never stopped dividing. Malignant tumors shed off and get into a person’s circulatory system. This is how cancer spreads and when it does, it is called, Metastasis.
  8. 8. Zephyr, Science Photo Library. Brain Cancer. 2011. Photograph. National Georgraphic. Web. 6 Dec 2011. This cancer patient is an example of Metastasis. The cancer (orange areas) began growth in the lungs before it spread to the brain. MRI images show the nine tumors. Magnetic resonance imaging. This image shows the two distinctions from a normal cell. 1) Loss of contact inhibition 2) Dividing indefinitely
  9. 9. Surprisingly, death does not occur from some chemical release or weird genetic property. As cancerous tumors grow, it takes up larger and larger amounts of room. Eventually the tumor presses up against important cells and tissues. It is the growth of the tumor that interrupts and stops organs from carrying out normal functions. Organ dysfunction like this can have dangerous results in our body when important tissues are affected. .. could be blocked, restricting our bodies from getting oxygen... could stop detoxification .. could be unable to pumpof toxins that go through our Blood through out body.Body.

  11. 11. The rapidly growing cell collection must be surgically removed or stopped. To slow down or stop the growth of a tumor, chemotherapy and radiation are used to interrupt cell division among the cancerous tumors.Terrible side effects are a result to chemotherapy. Not only are the cancerous tumorsslowed down in growth but other systems of the body are effected. For example,red blood cells are produced at a slower rate causing less oxygen to be produced.Patients endure extreme fatigue and shortness or breath.When chemotherapy interferes with the division of bone marrow stem cells, theproduction of platelets and white blood cells are reduced. This increases bruising,bleeding and the chance of infection.Hair follicles are also slowed down by chemotherapy.
