Ryan Mackinnon =Wiki post #1= The genetics of lung cancer Thursday, December 1, 2016

Due to the amount of people that have had cancer in my family I have chosen to write about the most common type of cancer that runs in my family. Lung cancer. I am also writing about this because learning about genetic information and how hereditary diseases are passed scared the shit out of me.

Lung cancer is a malignant tumour that starts in the cells of the lung. Malignant means that it can spread. There are two types of lung cancer. Small cell lung cancer usually starts in the bronchi that is in the middle of your lungs. Non-small cell lung cancer starts on the outer part of the lung in glandular cells. Small-cell lung cancer is more aggressive, meaning it can spread quickly to other parts of the body early in the disease. It is mainly from cigarette use and is rare in nonsmokers. Non-small-cell lung cancer grows more slowly and is more common. It's responsible for almost 85% of all lung cancers. media type="youtube" key="Out098oAdxs" width="560" height="315"
 * What is lung cancer?**



The picture above is a simple representation of what lung cancer looks like. Most people would think darker lungs (smoker lungs) would have lung cancer but that’s not always the case.

Some people get mutations of the cells from their parents that increase their risk for developing certain cancers. Even though inherited mutations are not thought to be a main cause of lung cancer, it can still play a role in the development of the cancer. Most of the time, the cancer cells are triggered with the inhalation of smoke or other poisonous gases.
 * How can you get lung cancer?**

Below are a few signs and symptoms of the early stages of lung cancer.
 * Signs and symptoms**
 * A cough that does not go away or gets worse.
 * Coughing up blood or rust-colored sputum (spit or phlegm)
 * Chest pain that is often worse with deep breathing, coughing, or laughing.
 * Hoarseness.
 * Weight loss and loss of appetite.
 * Shortness of breath.
 * Feeling tired or weak.[[image:lung c.jpg width="824" height="338"]]

=Wiki post #2= The Brain Tumor Thursday, January 16, 2017

Brain and central nervous system tumors are the second most common cancers in children, making up about 26% of childhood cancers. There are many types of brain tumors, and the treatment and outlook for each is different. Every day, 27 Canadians are diagnosed with a brain tumor and it is estimated that 55,000 Canadians are surviving with a brain tumor.

__ What is a Brain Tumor? __ There are two types of Brain Tumors, one is called Malignant which does contain cancer cells or Benign which do not contain cancer cells, a primary brain tumor is a tumor that begins in the brain. Brain tumors can occur at any age. There is not singled out humans that it effects. An interesting fact I read was, 688,096 Americans are living with brain tumors, but 550,042 tumors are Benign and 138,054 tumors are Malignant.



__ Symptoms of a brain tumor __ There are many symptoms that occur when you have a brain tumor but it also depends of the location of the tumor and the size of it, but some symptoms including headaches, numbness felling in your arms & legs, memory problems. Many mood and personality changes may occur.

media type="youtube" key="8N-6MR9CnRE" width="560" height="315" __ Treatments for Brain Tumors __ Often, low-grade tumors (grade I and II), which are not aggressive, are treated with watchful monitoring or surgery alone. Though all tumors are monitored with repeat scans, grade II tumors are watched more closely after surgery and over time to make sure there is no recurrence.

__ Tumor grade __ Doctors group brain tumors by “Grade” the grade of the tumor refers to the way the cell looks under the microscope. Grade 1: The tissue is Benign; the cells look nearly like a normal brain cells and they are growing slowly. Grade 2: Thee tissue is Malignant; the cell looks less like normal cells then do the cells in grade 1. Grade 3: The malignant tissue has cells that look very different from normal cells, the abnormal cells are actively growing. Grade 4: The malignant tissue has cells that look most abnormal and tend to grow quickly.



__ How are Brain Tumors normally diagnosed? __ Brain tumors are normally diagnosed by a doctor based on an amount of different test that were done, and based on medical history plus physical examination, An MRI is commonly used to help diagnose brain tumors. In some cases a dye may be injected through a vein in your arm during your MRI study.

__ Causes of brain Tumors? __ Often the causes of brain tumors are normally unknown, but in some cases the Benign Tumor could be linked to Genetics, could have been passed on from generation to generations, stress could have a large factor on this process, as well as inflammation or infections.
