Our project is breast cancer. our bodies go through regular cycles or mitosis every day when it gets the right chemical signal to create new cells. Sometimes there are cells that don’t obey the ‘rule’ and mutate causing a tomorrow. Some are benign and some are malignant. In this project, cells have become breast cancer. One of the breasts is not only carrying the tumor but it has significantly gotten larger in size.


  1. During the process of mitosis, cells die and new ones are created. Cancer cells however do not obey this process. They reproduce once and continue to divide when it is not necessary. This then causes there to be a malignant or benign tumor. We’ve talked about and gone through the mitosis process in class and in lab. We’ve discussed the occurrence of mutations during the process of cell division and what diseases can occur. In this paper, they go in depth with the relation between mitosis, the continuance of mutation and how it can turn into breast cancer.
    Defects of mitosis result in a number of nuclear abnormalities. Changes or mutations in DNA tend to cause breast cancer cells to become… well cancer. Tumor suppressor genes, which are genes that slow down cell division, help in DNA repair and send signals for apoptosis, may not be as active or even functional in cancer cells. If they aren’t functioning at an optimal level, cell divisions and replication (mitosis) will be out of control. Breast cancer is when the breast cells grow abnormally. The cells can divide more rapidly compared to healthy cells and continue to accumulate where it begins to form a mass. Mitosis (cell division and replication) is regulated by the tumor suppressor genes or anti-oncogene in order to help the cells grow in a normal matter. When a mutation occurs, this leads to various kinds of cancer to occur. The visual aide that is used shows the basic anatomy of breasts. You can see the nipple, muscle, fatty tissue, the ducts, lymph nodes and tumor. This allows us to envision the process and see the outcome of what leads to breast cancer.

  2. Michaela shows a great example of mitosis, the process by which a cell reproduces to create two identical copies of itself, and how cancer cells occur due to defects in the genes that control cell division. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell death. As a mass of cancerous cells grows, it can develop into a tumor. DNA is the chemical in our cells that makes up our genes. Genes have the instructions for how our cells function and how some DNA mutations are inherited or passed to you from your parents. Breast cancer is commonly found in women not men. Breast cancer can begin in all different parts of the breasts. There is no sure way to prevent breast cancer, but there are things you can do that might lower your risk, such as staying physical, cutting back on sugar consumption, avoiding or limiting alcohol use. Dietary or using hormone therapy have been suggested by studies that they can cause breast cancer. A benign tumor is a tumor that does not invade its neighboring tissue or spread throughout the body. Unlike a malignant tumor, which is a tumor that contains cancerous cells that may infect its surrounding tissue or spread around the body.Treatments for benign/malignant tumors depends on the stage of cancer, but it may consist of chemotherapy, radiation, and surgery to remove the mass.
