Cancer is the general name for over a 100 diseases. Even though they’re many kinds of cancer, every cancer starts from an abnormal growth of cells. Untreated cancers can lead to serious health risk including death.
Cancer can start almost everywhere in the body, which is over a trillion cells. In a normal cell state, the cells grow and divide to form new ones when the body needs them. When the cell is old or damaged, they die, and new cells take its place.
When cancer starts, the normal process is broken down. As cells start to deteriorate, they survive when they should die, and the new cells are formed when they’re not needed. These extra cells divide without stopping and they form tumors. Many cancers form solid tumors, but some do not such as leukemias.
Cancerous tumors are malignant, which mean they spread into tissues. Sometimes

Is cancer contagious? Should I stay away from relatives with cancer?
In the past, most people use to stay away from people with cancer. They were afraid they may catch the disease, but cancer is contagious. You cannot get cancer from someone else, even if you’re around them or touch them. Don 't be afraid to see someone with cancer, support helps ease the pain and the mental fear.
Some people argue that certain families get cancer more often but that’s not due to the fact that they live together. This has to due with the family sharing genes, unhealthy lifestyles, and the family being exposed to the same cancer agent.
Other people look at the clusters of cancer patients who have some type of contact and say that’s proof that cancer is contagious. But scientists have found that clusters rarely reflect a cancer. It’s very hard to be sure that environmental and personal factors are not the cause of the cancer.
4. Can stress cause cancer?
Scientists have done many studies and test to see if there’s a link between stress and cancer. So far there is no scientific evidence showing that a person 's stress is a factor for his/her
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 starts when cells in a part of the body start to grow out of control. Cancer cell growth is different from normal cell growth. Instead of dying, cancer cells continue to grow and form new, abnormal cells. Cancer cells can also invade (grow into) other tissues, something that normal cells cannot do. Growing out of control and invading other tissues are what makes a cell a cancer cell. Cells become cancer cells because of DNA (deoxyribonucleic acid) damage. DNA is in every cell and it directs all the cell’s actions. In a normal cell, when DNA gets damaged the cell either repairs the damage or the cell dies. In cancer cells, the damaged DNA is not repaired, and the cell doesn’t die like it should. Instead, the cell goes on making new cells that the body doesn’t need. These new cells all have the same abnormal DNA as the first cell does.
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...
Lung cancer is arguably the most devastating of all cancers, leading to more annual deaths than breast, prostate, and colon cancers combined (Crosta). 228,000 new cases are found every year (Marks) and there are approximately 1,370,000 deaths per year. Cancer in general accounts for 7.6 million deaths all around the globe. Cancer alone stands for thirteen percent of global deaths (Crosta). The percentage for the survival rate of lung cancer is a devastating sixteen percent (Marks)! More females are diagnosed with this cancer over men, but does not mean men cannot get this cancer as well. Actually, my uncle was diagnosed with lung cancer this past Summer. Shockingly, a couple of months later, my cousin, who I call my grandmother was diagnosed
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.
However, people who undergo chronic stress tend to develop unhealthy eating habits, or start smoking to help cope with stress. In which case stress can lead to lung 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.
While doctors are not always sure as to why one person is more susceptible to oral cancer then another, they do know that oral cancer is not contagious. There are no known forms of cancer that are contagious. There are certain risk factors that make some people more likely than others to develop cancer (Jones). Oral cancer is very dangerous because it is not usually noticed by the patient in its early stages.
“Just take my hand, together we can do it, I’m gonna love you through it.” (I’m Gonna Love You Through It- Martina McBride). Breast cancer is an awful disease that will change your life in a single moment. ”Everything in my life was turned upside-down. I really had a wonderful life; A husband, three children. And breast cancer came along and just smashed my world” (Janelle’s Journey). Breast cancer is an aggressive war that takes a great amount of fighting to survive. “You go from being perfectly healthy, to feeling like, ‘okay, I’m dying’. It started a whirlwind of things that I never anticipated having to go through.” (Bonnie’s Story- Beyond The Shock). Did you know that the youngest person ever to have been diagnosed with breast cancer
However most cancers mainly affect older people. Therefore as the average life expectancy in the United Kingdom has almost doubled, the risk of cancer has grown. It is estimated that a third of all cancers are caused by smoking and another third is caused by the diet people choose. These are over two hundred different types of cancer, and all have different causes, different symptoms and require different types of treatment. Some types of cancer are very common, such as breast, lung, bowel, and prostate cancer, whereas some types of blood cancers are very rare.
Cancer patients often wonder if going through treatments like chemotherapy and radiation are worth the risk of the side effects, in addition to the cancerous side effects. They feel that they can’t enjoy or relax in what a short amount of time they have left because they are bedridden from the nausea and pain that treatments put them through. Patients tell their loved ones to just let them die so long as they don’t have to go through any more pain. Those who are too old, are unable to recover from the effects, or are just too far in the grips of cancer, should refuse the more harsh treatments like chemo and radiation. On the positive side, refusing treatments after a certain point can save their families from the stress and cost of hospital bills. If caught early enough, patients can opt for safer and easier routes to getting rid of cancer like surgery or by doing a stem cell transplant.
Cancer is a really bad and deadly disease and has caused many deaths around the world, but what if it isn't much of a disease but instead a business, so on the off chance that you had a business offering something that made you well over a hundred billion dollars for every year, would you find a way to kill the requirement for your business? Or, on the other hand, would you bend backwards for cash to keep coming?Cancer is a really bad and deadly disease and has caused many deaths around the world, but what if it isn't much of a disease but instead a business. from food to medicine cancer-causing things are everywhere and put there on purpose for profit. The government has many pros of this too , they make money and thin the population.I just think it's terrible that people could be so selfish and then take lives for money and go to sleep at night. Most people are skeptical when people claim this ,but proof is everywhere and be careful so you don't become a part of the biggest business in the US.
Epidemiologists had identified many important causes of cancer by the early of 1980s. Many types of cancer vary in incidence by more than an order of magnitude between different populations and every type is rare in some part of the world. Many specific causes cancer are now known, the most common are by smoking, obesity and a few oncogenic viruses, but a large proportion of global variation for common cancers such as breast, prostate, colon and rectum remains unexplained (Peto J. , 2001). According to Richard Doll and Richard Peto, pollution accounts for 2% of all cancer cases and geophysical factors account for another 3% while 80% to 90% of cancers are caused by “environmental factors”. Environmental factors are the non-genetic factors which are smoking, diet, occupational exposure to chemicals and geophysical factors (naturally occurring radiation, man-made radiation, medical drugs and radiation and pollution.
Cancer develops when cells in a part of the body begin to grow out of
The topic that I will be focusing on for this assignment is on the screening of lung cancer, since this is one of the most controversial debates all across the world. The significance of this topic is that when it comes to lung cancer screening, many individuals may or may not abide by it. There are many reasons to why individuals may not want to have their screening done for lung cancer. The top two reasons are that the screening itself is expensive and secondly, the results that they get from the screening may not be accurate. Imagine, if the results came up as a positive, for the ones who really do not have lung cancer, the amount of pain, time and money that they have put into the curing of lung cancer, is painful. At the same, time it is not fair for them to go through this much, when they actually do not have lung cancer. In this paper, I will discuss how lung cancer screening is a controversial issue and why it impacts us as a society and what problems that the family members, friends and medical doctors have to face if something does goes wrong.. Here is a portion of my essay that will appear on the final copy of my essay.
