Cancer. A word that people dread and fear. For ages the thought of cancer scared people and they had no idea what to do about it. But today doctors and scientists are learning more and more about it all the time and it is not always a lost cause anymore. There is so many different kinds of cancer; brain, breast, lung, lymphatic, the list goes on and on. In 2012 my mom was diagnosed with brain cancer and my world was turned upside down, never to be the same again. She experienced all the treatments available and went through all the procedures that come with it. Origin of cancer. The Greeks first discovered cancer and they thought it looked similar to a crab and when it was translated into Latin, the Latin word for crab is cancer. Gupta Longati …show more content…
Tumors are abnormal growth of a tissue that is uncontrollable. There are two different types of tumors, benign tumors are always primary and only grow in one spot, never moving. Malignant tumors are considered cancerous, usually start somewhere else in the body and then spread. They also grow very fast. The causes of cancer are not always known. It may have come from chemicals in the environment, radiation, smoking, viruses, and sometimes those genes are the problem. Diet and the acidic environment in the body can also play a big part in it as well. Cancer begins when certain cells in the body start to grow out of hand. All cells have the potential to be cancerous, but few make it to that point. There are a multitude of different kinds of cancer, but they all start out the same way, irregular cells growing uncontrollable. Brain cancer affects the ability of the nervous system to function properly. The brain uses all of the stimuli it receives from the nervous system to direct and send impulses to all the organs in the body to function. Brain cancer disrupts the signals and the body can't work as well as it …show more content…
Number one that people immediately think of is surgery. Surgery can be very effective in getting rid of the cancer. But sometimes part or all of the cancer is in a part of the brain that is inoperable so they can't remove it. In that case they get what they can out and then use other methods to try and get rid of the rest. These options include chemotherapy and radiation. Chemotherapy is not always used to treat brain tumors as the blood-brain barrier can prevent some drugs from reaching the cancerous cells. And it can sometimes make the symptoms worse and end in death. The most common therapy is radiation, the tumor is irradiated with beta, x rays or gamma rays. Radiation has some bad side effects, it kills the cancer cells in your brain, but it also kills other cells in the brain as
There are two main categories of brain tumors as to the seriousness; Malignant, and Benign. A Malignant tumor can grow and spread aggressively, and overpower other healthy cells by taking their space, blood, and nutrients. A Benign tumor is less serious than a Malignant, however, it can still cause many problems in the brain by pressing on nearby tissue. They are typically slow growing and rarely spread to other parts of the body. Benign brain tumors can be considered Malignant if they are located in areas of the brain that control vital functions like breathing. Unlike benign tumors, the cell structure of a malignant brain tumor is largely different than normal brain cells. Malignant tumors tend to grow faster and can be more invasive than benign tumors. They are also are life threatening. Tumors are classified as grades one through four. The more aggressive a brain tumor is, the higher the score. Another type of tumor is the pituitary tumor. A pituitary tumor is an abnormal growth of cells in the pituitary gland. It’s about the size of a pea and it’s located at the center of the brain behind the nose and eyes. "Malignant and Benign Brain Tumors."
There are two types of Malignant Brain Tumors: Primary, and Secondary (Metastatic). Primary Brain Tumors begin in the brain, or in nearby tissues such as the meninges, cranial nerves, pituitary gland, or pineal gland. A Primary Brain Tumor begins from a mutation in the DNA. Metastatic Brain Tumors are more common, and occur from having had cancer in another part of the body, which spread to the brain.
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).
Cancer has become the one of the most feared things for human beings. The various type of cancer have been discovered and there are still a lot of it that undiscoverable. Cancer is a complex disease that have a group of disease. The cancer itself cannot be describe by words. The causes of this cancer is still not being able to be discovered fully. There are only minor factor that can lead to this disease. The carcinogens are believed to be one of the causes that lead to cancer such as asbestos, radon gas, tobacco, PVC and much more from our chemical industries. The environment especially near to the industrial that produce chemical waste can be one of the causes lead to cancer. Cancer also have relation with our age, lifestyle, and diet and also can be genetically inherited. It is believed that older people have higher tendency to get cancer than younger people. Our lifestyle and diet also plays a role causing a cancer by our daily life routine. Smoking tobacco and eating unconsciously (still in research) can also increase the possibility to get cancer especially lung cancer that cause by smoking tobacco. There are several cases, cancer were inherited from their parents. Various type of viruses such as HIV, HPV, EBV and many more virus has a high capabilities to increase the chance a patient to get a cancer because these viruses lower their body immunity to disease.
According to SEER Statistics, 23,380 people are estimated to get a brain or nervous system cancer diagnosis. Out of those people, 14,320 people are estimated to die from their brain or nervous system cancer diagnosis (National Cancer Institute). Cancer is a type of dangerous tumor, or a buildup of extra cells that form a mass of tissue, that can be life threatening (National Cancer Institute). The term for a tumor that is cancerous is a malignat tumor, whereas a benign tumor does not contain cancer cells (National Cancer Institute). According to the National Cancer Institute, the causes of brain cancer are unknown, but risk factors include family history and excessive radiaton exposure. Although they are not always due to a brain tumor, comon symptoms include headaches, nausea, speech, hearing, vision, and mood changes, problems with balance and mamories, seizures, and numbness in arms and legs (National Cancer Institute). MRI and CT scans as well as surgical biposies (or the removal of part of the tumor to be examined) are used to diagnose brain cancer (National Cancer Institute). Different types of treatment options include radiation therapy, surgery to remove the tumor, and chemotherapy. According to Charles Davis, MD, PhD and Nitin Tandon, MD of WebMD.com, chemotherapy is “ the use of powerful drugs to kill tumor cells”. There are a few different types of chemotherapy, but all of which bring out the same kinds of side effects. Although the physical side effects of chemotherapy are commonly known, few people know of the emotional toll chemotherapy can take on a patient and his or her family as they go though this process.
A brain tumor is abnormal growth of tissue in the brain or central spine that can disrupt proper brain function. Doctors refer to a tumor based on where the tumor cells originated, and whether they are cancerous (malignant) or not (benign). Benign: The least aggressive type of brain tumor is often called a benign brain tumor. They originate from cells within or surrounding the brain, do not contain cancer cells, grow slowly, and typically have clear borders that do not spread into other tissue. Malignant: Malignant brain tumors contain cancer cells and often do not have clear borders. They are considered to be life threatening because they grow rapidly and invade surrounding brain tissue
Cancer gets its name because of the finger-like projections spreading from its center mass make it look like a crab, and the Greek work for crab is cancer, and oncos is the Greek work for “swelling” which is now used as the name for
The exact cause of a tumor is an enigma, but scientists have scrutinized tumors and have discovered several factors that result in a higher risk of developing one. A change in the genetic structure of a cell is usually what induces a tumor. The mutation can either be inherited or caused by the environment. (Understanding
Lung cancer may cause specific symptoms. The sypmptoms which are often described as assyndromes, some of the examples are:Horner syndrome,This type of cancer affects the top part of the lungs, which the doctors call Pancoast tumor. It may destroy the nerve that pass through the upper chest into the neck. This causes severe shoulder pain. Normally the tumor causes a group of signs and symptoms known as the Horner syndrome.
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.
There are many different types of cancer that are actually deadly or that can be cured if found quick enough. The first cancer I have come across is a cancer of the stomach called gastrointestinal stromal tumors. This type of cancer spreads through the inner part of the stomach and begins to transpire if it is not caught in enough time. My mother actually passed away from this cancerous stromal tumor. The symptoms are loss of weight, loss of appetite, nausea/vomiting, abdominal pain or discomfort.
The treatment for lung cancer depends on what type and what stage the cancer is on. If you have non-small cell lung cancer is treated by having surgery, chemotherapy, radiation therapy, targeted therapy, or with a combination of all these treatments all together. Doctors can use all those treatments to treat non-small cell lung cancer. The treatments that you need to treat small cell lung cancer are with radiation and chemotherapy. (Lung Cancer,
Cancer is a genetic disease that is caused by the changes to genes that control the way our cells function, especially how they divide and grow. Genetic changes that cause cancer can be inherited from our parents. They can also arise during a person's lifetime as a result of errors that occur as cell divide of because damage to DNA caused by certain environmental exposure. In general, Cancer cells have more genetic changes, such as mutations in DNA, than normal cells. Some of these changes may have nothing to do with cancer,
I would not be the only one to admit that when I hear the word cancer, I cringe. I know how broad the topic is but I want to focus on one specific form of cancer and that is Leukemia. When my cousin, Johnny, was diagnosed with Leukemia at the age of 12, we had to familiarize ourselves with the term. We knew that it was cancer and that people die from this disease and that it wasn't contagious but we still were scared that it might somehow jump from his to us. That is because we were ignorant to the disease. We didn't realize the toll that would have on his body or how he felt.
Cancer is a disease of abnormal cells in which they divide uncontrollably and can eventually metastasize throughout the body. Cancer actually is not just one disease; there are over 100 types of cancer and are usually named after the type of cell/organ that they began in. Brain cancer can be classified into two groups: metastatic and primary brain tumors. Metastatic brain cancer begins in another organ and ultimately spreads to the brain. Primary brain tumors begin when malignant cancer cells arise in brain tissue. The long term prognosis of brain cancer varies from less that 10% to 32%. Children usually have a better projected outcome as 75% will survive longer than five years. Without proper treatment of the cancer it can result quickly in death. Brain cancer is a very harsh disease and only has a few effective treatments.
