It takes a complicated process for cancer to occur, but thanks to your Advanced Biology class, we are here to inform you about the possible pathways in which cancer can occur. Everyday your cells grow, die and multiply without you even noticing. Cells die all the time and the body must replace these dead cells. In the cell cycle, the cells go through a growth and division process. In order for a cell to go through cell division, it must go through the process, interphase. Interphase includes; G1, S, G2, and M phase. During G1, the cell grows and performs its specific function inside the body. In S, or synthesis phase, the DNA inside the cell nucleus is replicated preparing the cell for cell division. The cell then enters G2, a second growth phase, to continue to grow and prepare for cell division. The final phase of interphase is M or mitosis is where cytokinesis …show more content…

Mutations are alterations in a cell’s DNA sequence, which is essential when cells divide to create healthy cells. Mutated DNA create cancerous proteins that turn cells cancerous. DNA is the blueprints in your body needed to create the right proteins in order for your body to function correctly. The two major categories of genes in regulating the cell cycle, are proto-oncogenes and tumor suppressor genes. Proto-oncogenes regulate cell growth, and when mutated, they turn into oncogenes. There are various pathways in controlling the cell cycle through the mutation of a proto-oncogene, such as the production of cancerous RAS, E2F and cyclin proteins. Tumor suppressor genes fix faults in DNA, slow down or stop the cell cycle, or enter the apoptosis phase which tells the cell to die. Tumor suppressor genes essentially act as brakes for the cell by telling the cell to stop dividing or stop growing. One mutation does not cause cancer, but the build up of multiple mutations can cause

In the US, cancer is the second major cause of death. Cancer is the uncontrolled division of somatic cells caused by defective cancer cells. Usually, when cells divide, they begin to form a layer. Normal cells will experience contact inhibition, where cells can cease to replicate once there is no more space for it to inhabit. However, cancer cells cannot control their division.

In A-T the ATM gene is disrupted in the making of proteins that regulate cell growth. These mutated genes do not repair DNA damage instead they allow for these defects to be spread into other cells. This allows for uncontrolled division and growth of cells which can lead to cancerous tumors. These mutations also allow for unwanted cell death which leads to the loss of important cells in the brain involved with coordination. People who are carriers of a mutated ATM gene are likely to develop one of the following cancers: breast, stomach, bladder, pancreas, lung, and

If we can use the immune system in our favor then we can be able to stop these mutations from happening uncontrollably. Now, when we look at the environmental aspect of this example we can be able to change the milieu so that the cancer is able to leave the body completely, which is something that doctors are trying to find. A milieu is a person’s extra-cellular fluid environment, more particularly the interstitial fluid, and its physiological capacity to ensure protective stability for the tissues and organs around it. Rather than killing something, we want to be able to grow something that will lead us to our

Cell Division is an extremely important aspect of Cell Biology and is essential for scientific studies surrounding cells. This is evident in health studies such as the growing research surrounding cancers. This annotated bibliography describes a number of generic articles which focus on giving the reader an overview of the respective topic rather than an in depth analysis. 1) This journal article reviews the cell cycle and takes the reader through its processes.

If you find out that you have developed cancer, your mind must immediately go into recovery mode. While it is impossible to learn everything you need to know overnight, this article can give you a few tips for dealing with cancer. When you have cancer, it affects everyone in your life, especially those closest to you. There are many ways to deal with cancer, so consult with a doctor regularly.

What is cancer? Cancer takes place when the normal cell growth and propagation is disrupted and abnormal cells divide and grow in an unrestrained way. This would spread into the other tissue of your body.

1) The city states of the ancient Mayan empire flourished in southern Mexico and northern Central America for about six centuries. Then, around A.D. 900 Mayan civilization disintegrated. Scientists have found that drought played a key role. The Mayans appear to have exacerbated the problem by cutting down the jungle canopy to make way for cities and crops, according to researchers who used climate-model simulations to see how much deforestation aggravated the drought. The earliest Mayans were growing crops such as maize, beans, squash and manioc.

Cancer is a disease that often times is not noticed until very late when it is already terminal. This was the case with Nancy Johnson, she noticed a small lump on her right thigh that refused to go away. This poses the question, how can a cell transmogrify into this awful, malignant tumor whose only goal is to grow and infect the surrounding cells or other parts of the body. Especially in older women the chances of getting cancer as they endure more menstrual cycles, opening the possibility for cells to malfunction and form into cancer cells. Because it is difficult for individuals who have cancer to determine what is wrong with them, as you age they begin to give tests every few years to test and see if you have any cancerous growths.

Cancer is a broad term encompassing more than one hundred different diseases, but all cancers start in a single body cell. Cells become cancerous when the cell’s DNA becomes damaged, typically through replication errors or from environmental factors such as being exposed to radiation or ultraviolet (UV) rays. When DNA is damaged in a normal cell, the cell either repairs the DNA or dies if the DNA cannot be repaired. In a cancer cell however, the DNA is not repaired, but the cell does not die as it should. Instead of dying, the cancerous cell undergoes the cell cycle to grow and divide to form new and abnormal cells.

FASTING AND CANCER Professor David Khayat explains on February 2, 2012 in an interview that "cancer is not a disease". For years scientists have been searching for the molecule that could fight this disease. Since 2011 we have confirmation that cancer is a mutation of the cell with alteration of genetic heritage. Most of the time mutant cells die. Nevertheless in the case of cancer, the cells that mutate are adapted to their environment and live.

Cancer can develop more fast when your body stops working well the cells. If the old cells of your body die, new cells grow up forming new cell, but if these cells stop growing up this can affect the body and this create a defective cells. These extra cells may form a mass of tissue and your body can form a malignant cancer and expanding into your body. Cancer is a group of many related diseases with old cells. Cells are a very small units that you can see only with a telescope and doctors study them carefully to know if there can develop malignant cancer.

For instance, loss of histone acetylation, which is controlled by histone deacetylases (HDACs) results in gene repression. Oftentimes, HDACs are found to be profoundly overexpressed in various forms of cancer. (Song et al., 2005) Histone acetyltransferases (HATs) which together with HDACs function in the process of histone acetylation are too altered aberrantly in cancer. (Yang, 2004)

Cancer is an abnormal production of cells that divide uncontrollably within the body (Black & Hogan 2006). What is more vaguely understood are the mechanisms the underlie this, the different effects on each patient, and how to stop it. Some common types of cancer are breast cancer, prostate cancer, skin cancer, leukemia, and brain cancer. Each of these various diagnoses cause different biological and psychological stresses on the patient. Because old cells do not die and instead grow out of control, often, a mass will form, otherwise known as a tumor.
