Lung cancer is the leading cause of cancer death and the second most diagnosed cancer in both
Smoking tobacco is one of the main causes of lung cancer. More than 8 out of 10 lung cancers (80%) are caused by smoking. This also includes breathing in other people’s cigarette smoke. Even occasional smoking increases the risk of lung cancer.
Lung cancer is the most commonly diagnosed cancer in the world, according to the World Health Organisation. In the UK, it 's the second most-frequently occurring cancer among men (after prostate cancer), accounting for 1 in 7 new cases, and the third most-frequently diagnosed cancer in women (after breast and bowel cancer) accounting for about 1 in 9 new cases. However, numbers have dropped considerably in recent times, by about 16% in the last decade alone.
A common form of cancer that is very popular today is lung cancer. Lung cancer is a very dangerous form that can cause problems in simple body functions. These simple body functions are short breath and general fatigue. Lung cancer is commonly formed from smokers that has been exposed to that activity for numerous years. Lung cancer can also be spread by being exposed to asbestos or other pollutants. This form of cancer has many risk factors to it. These risk factors are high levels of air pollution, arsenic drinking water, and radon gas. Radon gas is a gas that is highly radioactive and is very sensitive to the body. Once radon is exposed to the body, it has a very high respiration rate which initially divide its radioactive cells- causing more significant damage to the body.
Lung Cancer, like any other type of cancer, is the uncontrollable growth of cells in the lung tissue. The main causes that contribute to lung cancer include inhaling carcinogens (basically, smoking), exposure to ionizing radiation, viral infections and even air pollution. These factors basically damage the tissues lining the bronchi in the lung, leading the cancer to develop further (Vaporciyan & Nesbitt JC, 2000). Primary lung cancers that develop in the epithelial tissues of the lung are known as carcinomas and claim the top spot in terms of leading cancer-related death causes. As of 2004, lung cancer
Lung cancer is a cancer (malignancy) that originates in the tissues of the lungs or the cells lining the airways. Lung cancer originates when normal lung cells become cancer cells, usually after a series of mutations, and begin to divide out of control.
The leading cause of cancer death for both men and women in the United States and worldwide is lung cancer. Lung cancer is responsible for thirty percent of cancer deaths in the United States. The deaths caused by breast cancer, colon cancer and prostate cancer combined do not add up to the deaths that lung cancer causes. In 2007, 158,683 people, 88,243 men and 70,354 women died from lung cancer in the United States (Eldridge, 2012). Out of the 158,683 people that died from lung cancer in 2007, 135,000 of them died of lung cancer caused by smoking cigarettes. The overall survival rate of those with lung cancer is at about fifteen percent.
Lung cancer is a genetic and acquired disease. Lung cancer is genetic because cancer in general is caused by changes to the genes that control the way our cells function, especially how they grow and divide. All of these changes include mutations in the DNA that makes up our genes. Genetic changes that increase cancer risk can be inherited from our parents, if the changes are presents in germ cells. Which are the reproductive cells of the body, those are the eggs and the sperm. Lung cancer is also acquired because as the result of errors that occur as cells divide a person’s lifetime or exposure to certain chemicals. Some examples of these chemicals are found in tobacco smoke, radiation, UV rays from the sun that damage DNA. “In general, cancer cells have more genetic changes than normal cells. But each person’s cancer has a unique combination of genetic alterations.” Some of these changes may be the result of cancer, rather than the cause. As the cancer continues to grow, additional changes will occur. Even within the same tumor, cancer cells may have different genetic changes.
Lung cancer is a tumor that affects either one or both of the lungs.A primary cancer begins in the lungs and a secondary cancer begins in another place in the body and makes its way up towards the lungs. Lung cancer is the 5th most common cancer. In Australia 59% of males were diagnosed were as 41% of Australian females were diagnosed.
Lung cancer is a type of cancer is found in men and women lung cancer have something to do with your lungs. Your lungs which help pump oxygen into your body and also release carbon out of your body which helps you live because you need oxygen. Lung cancer is a common cancer in ages 60 and up it can also be found in any age but is most commonly in 60 year olds and older. Lung cancer is the leading cause of cancer deaths in the U.S. in both men and women. Lung cancer is also one of the most preventable kinds of cancer, but smoking is mainly the leading cause of lung cancer.
Over decades, lung cancer globally continues to be the leading killer in both genders. In the United States, smoking is responsible for 90% lung cancer deaths in men and about 80% in women. About 15 decades ago, lung cancer was not considered as the leading killer because it was an extremely rare disease about 1% in total of cancer cases. However, by the year 1927, the percentage increased into 14%. During World War I, many soldiers and civilians started smoking to release stress. Eventually, that made the lung cancer rate and smoking addiction in the population started to increase. In a research that published in 2001, lung cancer annually kills over one million people worldwide (Witschi, 2001). The death rate, which caused by lung cancer,
Lung cancer is the leading cancer killer of men and women in the U.S. The main cause of lung cancer is smoking. (Health Risks, n.d.) Smoking weakens our body’s immune system due to the chemicals (carcinogens) that are found in cigarettes. People don’t realize how damaging these chemicals are in their bodies or maybe they do and just don’t think it will happen to them. Smoking not only causes cancer it, also causes other health issues such as heart disease, COPD, obesity and many others. The sad thing is cigarette companies know they are slowly killing people, yet they continue to advertise and sell their products. Although, this isn’t very hard for them to do with all the help they get from actors and actresses making films with them smoking. This is why kids start smoking at such a young age, because they see actors/actresses they idol doing it.
Lung cancer is the most common cancer-related cause of death among men and women. Lung cancer can be undetected for many years causing it to become more dangerous and possibly fatal. There is not cure for lung cancer or any cancer, but if detected in an early stage the lung cancer can be detected, treated, and hopefully terminated. There are many new and developing treatments being tested now that may save lives in the future. Through understanding what the lung cancer is, doctors can easily diagnose and assess cancer patients.
Cancer is the most significant cause of death for both men and women is measured to be the main cause of cancer decease worldwide, and it is complex to detect in its early stages because symptoms emerge only in the advanced stages causing the mortality rate to be the highest among all other types of cancer. More people die since of lung cancer than any other types of cancer such as breast, colon, and prostate cancers. There is major evidence indicating that the early detection of lung cancer will reduce mortality rate. The majority recent estimate according to the latest figures provided by world health organization indicates that around 7.6 million deaths worldwide each year because of this type of cancer. Furthermore, mortality from cancer
Lung cancer occur when the lung cell become abnormal and grow uncontrollably till they form into a tumor and spread to other areas of the body. Lung cancer is among the leading cancer in both men and women. Estimate about 1 out of 4 deaths recorded cause by lung cancer. It is usually occur mainly in an older people which is 65 year and
