What is cancer?
Cancer is a topic that is always being talked about in the medical field. It is regarded in 4 stages, the first being the least intense and the fourth being the most intense. Cancer is a disorder in the process of cell division. During cell division 90% of the time the cell is in interphase with means the cell is growing/developing and working on replicating DNA, while also working on other cell functions. When a problem occurs, the cell likely skipped a certain checkpoint during interphase, hence not allowing the cell to carry out its functions. Mitosis, on the other hand, is about 10% of the cell cycle. This is the process of cell division creating another cell. The function of mitosis is important for cell growth and repairment of cells if the body is injured, but an unhealthy amount of cell division and replication, i.e. mitosis, can be dangerous. This can cause a tumor and lead to cancer. GOOD A kind of cancerous cells that have the ability to spread are malignant cells. Malignant cells are a result of over replication of cells in mitosis.

Apoptosis is a natural cell process through the immune system that sends messages to the cell that is not functioning correctly to self-destruct and die. Ultimately, apoptosis helps prevent cancer (World of Genetics, 2007). This process occurs quite frequently and stops the cell from continuing cell division/ mitosis. When this natural cell process does not transpire then the cell will not function properly. Then replication will go wrong and the cells can potentially become a tumor leading to cancer (Xu, Qiao,Linke , Cao, Furth,.Deng, 2001). Cancer can potentially occur less if apoptosis took place more. Of the many types of cancers, kidney cancer is among one of the most known cancers and one of the worst cancers to have. Hence, there is not enough information and treatment for kidney
Cancer is the term used to describe a group of diseases consisting of hundreds of ailments and although there exists so many different types of cancer, they all begin in a similar way. The body is made up of over a trillion cells, and cancer is the uncontrolled growth of malfunctioning cells in the body (Dawson, 1996). “Normal body cells grow, divide, and die in an orderly fashion. During the early years of a person’s life, normal cells divide faster to allow the person to grow. After the person becomes an adult, most cells divide only to replace worn-out or dying cells or to repair injuries” (American Cancer Society, 2012).
Colon cancer is a deadly cancer but sometimes you can survive through it if you find out sooner that you are diagnosed with colon cancer. People that are older than 50 are usually diagnosed with colon cancer. Colon cancer can spread different part of your body and cause you a lot of pain. Doctors have found some treatments to fix colon cancer but when you are on stage three or four sometimes there is nothing that they can do. Doctors are working hard to find new treatments and maybe someday colon cancer would not be a cancer that can kill you anymore.
The world we live in can be wonderful at times,but can also be dangerous and danger isn’t a good place to start at.The word cancer seems terrifying when someone thinks about it and they should be because there is a lot of types of cancer from all over the word.Cancer is the leading causes of death everywhere you go and it happens from different parts of the body.From someone that doesn’t understand cancer it’s very important to know about the aspects in which they come around.They way a cancer forms,symptons that are caused,and the way each cancer type is treated is very important to consider.
Cancer is a very large issue in the world. Cancer is a sickness that can lead to many life threatening problems and can eventually lead to death. There are many different kinds of cancer that can effect a person without them even knowing it is there. One type of cancer that can be easier to detect would be skin cancer. Skin cancer can be diagnosed by seeing a doctor or dermatologist, if they see an abnormal mole or spot on your skin, they many ask to remove the spot and test it in their laboratory. If the spot or mole comes back positive for skin cancer, they next will run more tests to see if it has spread throughout the body. The first thing the doctor will ask you is the time frame from when you first started noticing this on your body,
To understand more about this disease I did a research on it, and according to the National Cancer Institute: “Cancer is a term used for diseases in which abnormal cells divide without control and are able to invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymph system”. Also, there are more than 100 different types of cancer. Cancer is not a single disease, but a group of related diseases.
According to “Medical News Today” cancer is a disease that is caused by an over growth of anomalous cells on one or more lungs. Cells often go up the air pipes which can cause difficulty to breath. Due to the over production of cells the tissue cells often begin to over produce; which results in tumors. There are two types of tumors: malignant and benign. Malignant tumors are the more dangerous of the two due to its invasive nature; which makes it cancerous. While benign is not invasive in other words non-cancerous. This is why cancer spreads to multiple areas and can be sometimes very difficult to fight. Cancer cells are abnormal not only because of their evasive nature, but also because of its irregular life cycle. Rather than expire like a regular cell, they continuously grow and duplicate which causes the disease to spread. This makes cell abnormal in shape and other qualities; known as a sickle cell. Due to the large growth and reproduction rate of the cells this makes the spreading of the cancer more rapid. Each cancer has specific symptom, for lung cancer the sympto...
Cancer occurs when cells divide uncontrollably. Cells keep dividing even though new cells are not needed. Change from normal to cancerous cells requires gene alterations.
Cancer is the name given to a collection of related diseases. In all forms of cancer: the cells in the body begin to divide uncontrollably and then spread into the surrounding tissues.
Usually, normal cells die when they are old or damaged, newly grow cells will replace them. However, if something goes wrong, there may be too many new cells when the body only needs a few of them, and the body can’t get rid of old cells, it builds up a mass of tissue called tumor. There are two types of tumor, begin or malignant. Begin tumors are usually not harmful to human body, however, malignant tumors could be life threatening. This type of tumors will invade organs and tissues around them, travel through blood vessels or lymph vessels, attach to other tissues and destroy them. Malignant tumors arise in breast tissues and cause breast cancer.
Cancer is a deadly disease that affects millions of American families each year. In cancer, cell division isn't controlled. Usually, cells have to go through a set of checks and balances before they divide, in cancer that is nonexistent. The cells just keep duplicating until they eventually form disorganized clumps called tumors. Tumors can either be, benign, meaning that they do not possess the power to metastasize to surrounding areas. If a tumor has the power to metastasize, it is classified as a malignant tumor. In simple terms, a benign tumor is not cancerous, and a malignant tumor is. Cancer cells cannot perform the necessary functions they were created for. Some types of cancers, like pancreatic cancer, cannot be cured. Other cancers such as melanoma and breast cancer have high survival rates when caught early. The four major types of treatments used to treat cancer include, surgery to remove the affected organ, radiation, chemotherapy, or biological treatments.
Cancer is a term used for diseases in which abnormal cells divide without control and begin to invade other tissues. The term cancer is also used when cells start to produce too quickly when there are not enough cells dying. Cancer cells are also called malignant cells. Cancerous cells are able to invade other healthy cells and can spread to other parts of the body through the blood and lymph systems.
For years, people have been looking for a cure for the devastating disease of cancer. Cancer is the third highest killer in the US, with over 2,500,000 victims per year. Oncologists and scientists around the country are researching all forms of cancer in an effort to understand, treat, and ultimately defeat this disease. Already there have been numerous advances in the field, such as chemotherapy and gene therapy. One advance has been the use of a cell process known as apoptosis.
Apoptosis: A process where when a cell receives a specific signal, is damaged, or is stressed a cell becomes programmed to die which causes the cell to decrease in size and is attacked by macrophages causing it to break into smaller pieces.
In every cell within an organism, the most crucial question is to survive or to die. In life, cell death is required so as to allow normal function. Cell death can be either physiological or programmed, in a process known as apoptosis. Cells that undergo apoptosis generally produce a wide range of morphological changes. These changes include shrinkage of cell, membrane blebbing, chromatin condensation and nuclear fragmentation. Apoptosis occurs due to the presence of a family known as the caspases. Apoptotic cells are then cleared by phagocytosis in vivo, where phagocytes swallow up the dying cells and digest them. [1]
Despite the benefits of PI, there continues to be a problem in determining which (PI) methods works best for student achievement in Title I middle schools. Anderson and Keith, 1997; Jodl, Michael, Malanchuk, Eccles, and Sameroff, 2001 cited in McLoyd, Hill, and Dodge (2005), suggest that “decreased parental school involvement in middle school may be due to the adolescent’s desire for autonomy and independence” (p. 236). Bhargava and Witherspoon (2015) further believe that when youth independence increases along with failing grades, parental involvement in education is vital.
