MI 3.1: Detecting Cancer


National Cancer Institute Cancer.gov



Cancer is a broad term used to encompass several malignant diseases. Cancer is the second leading cause of death in the United States, second only to heart disease. Half of all men and one-third of all women in the United States will develop cancer during their lifetimes. Although cancer is a term that encompasses more than 100 different diseases and affects different people differently, all cancer cells share one important characteristic. Cancer cells are abnormal cells in which the processes that regulate normal cell division are damaged. Most cancers are initially recognized when signs or symptoms appear. Once cancer is suspected, it can be further investigated through medical tests including X-rays, CT scans, and MRI scans. Finally, the definitive diagnosis requires the histological examination of a tissue specimen, called a biopsy. Once a diagnosis is confirmed, treatment can begin. The more that is known about the cancer, the more effective the treatment can be.
Common Types of Cancer

Skin cancer is the most commonly diagnosed cancer among men and women. Over one million cases are diagnosed each year, with more young people having skin cancer than ever before. The most common types of cancer in the United States based on frequency of diagnosis are:
bladder cancer
breast cancer
colon cancer
endometrial cancer
kidney cancer (renal cell)
leukemia
lung cancer
melanoma
non-Hodgkin lymphoma
pancreatic cancer
prostate cancer
thyroid cancer

PBS 3.1.1 CRIT, Blood Detectives

Hematocrit  "CRIT"

 The hematocrit measures how much space in the blood is occupied by red blood cells. It is useful when evaluating a person for anemia. Blood drawn from a fingerstick is often used for hematocrit testing. The blood fills a small tube, which is then spun in a small centrifuge. As the tube spins, the red blood cells go to the bottom of the tube, the white blood cells cover the red in a thin layer called the buffy coat, and the liquid plasma rises to the top. The spun tube is examined for the line that divides the red cells from the buffy coat and plasma. The height of the red cell column is measured as a percent of the total blood column. The higher the column of red cells, the higher the hematocrit. The hematocrit test can also be done on an automated instrument as part of a complete blood count. It is also called Packed Red Cell Volume or Packed Cell Volume, or abbreviated as Hct or Crit. The test is covered by insura
nce when medically necessary. Results are usually available the same or following day.

Sponsor A Family note

Hey H and M kids, its that time of year again! It is time to give back to our community and start collecting items for Sponsor a Family. You will find a little snowman to the right of this post that has a link to the kids we are buying gifts for. Find your class hour and table color and coordinate with your table what gifts you want to buy, maybe even make a chart to make sure you cover everything on the list! In addition to gifts, Meijer, Kroger and other grocery store gift cards are much needed for meals during the holidays!! We are hoping to collect all items by Monday, December 19th so we can have adequate time to fill in any gaps. We will wrap these gifts and deliver them on Thursday, December 22nd. In addition, this year we are adding Hygiene/ Toiletry baskets/boxes. We will compile boxes of detergent, soap, shampoo and conditioner, deodorant, feminine hygiene products(pads, panty liners, etc) and fabric softener, in addition to any other hygiene products that could be useful to the families that they may not have access to. These we will put together on Wednesday, December 21st and delivered to the schools to be handed out to the families in need. Thank you for all your donations, lets make this year the most successful yet and show these families love! Cassie Ritter H&M Lead

PBS Act 2.3.3 Diabetes Complications


What the heck is hemoglobin A1C?

An A1C test measures the percentage of glucose-containing red blood cell molecules present in the bloodstream.
Hemoglobin is an important protein in red blood cells that’s used to transport oxygen from the lungs to the rest of the body. There are several types of hemoglobin, the most common of which is hemoglobin A. When glucose molecules combine with hemoglobin A in the bloodstream, the resulting molecule is called hemoglobin A1C.
The more glucose in the bloodstream over a given amount of time, the more hemoglobin A molecules become hemoglobin A1C molecules. And of course, with diabetes, you want to keep that level of glucose as normal as possible. The proportion of A1C molecules in the blood is measured by an A1C test—that’s why it’s reported as a percentage.
David B. Sacks of Harvard Medical School and Brigham and Women’s Hospital describes it: “The way hemoglobin A1C forms is that glucose in the blood goes into the red blood cell and attaches to the hemoglobin. The more glucose in the blood, the more will stick onto the hemoglobin.
“The red blood cell lives in the blood for approximately 120 days because of the long lifespan of the red blood cell. So hemoglobin is there longer, and more glucose is stuck to it—so A1C is reported as a percentage of total hemoglobin in the blood.
“An A1C of 7 means that 7 percent of the hemoglobin has glucose stuck to it.”
