What is prostate cancer
Prostate cancer is one of the greatest scourges of the male sector of the population. It is also one of the most common diseases within that social branch, and early diagnosis can save many lives. There is a massive aversion to the conduct of tests for the detection of this cancer, but is very necessary to be carried out in order to treat properly in the event of his appearance.
After 40 years of age is almost obligatory to do prostate exam every year. The most common is the digital rectal examination performed by a urologist, although there are several studies and analysis that can be used for the detection of cancer. Older people are more prone to this disease, which is very important to make an annual inspection to avoid any kind of surprise.
The list of symptoms of this disease is quite varied. If you experience any of these, you better do a check with your doctor you trust: painful urination, loss, blood in excreta and muscular pain in the spine area, groin and testicles. Remember that early diagnosis can help an effective treatment that reduces the risk of death.
Nor is it a matter of living scared, but it is always useful to encourage prevention. Note that maintaining good eating habits and physical activity significantly decreases the risk of prostate cancer. Also, remember that familial predisposition is also a condition to have this condition.
Main Factors and Treatment of Lung Cancer
Smoking increases from 10 to 25 times the risk of being diagnosed with lung cancer. This is by far the main risk factor.
Other factors may also play a role, such as:
* Secondhand smoke;
* Exposure to carcinogens (asbestos, radon, gasoline fumes, etc.).
* Smoke wood stove;
* Frequent exposure to air pollution;
* Have a diet low in fruits and vegetables.
Preventing
* Do not smoke or quit.
* Avoid secondhand smoke.
* Adopt an anticancer diet (more fruits, vegetables, whole grains, less red meats and sausages; avoid excess calories).
* In an area where radon levels are high, to analyze the air in his house to check the radon level.
The Dangerous of Residual Cigarette Smokes
The risk of exposure to snuff does not end when you turn off the cigarette. It is well known the danger faced by passive smokers inhaling the smoke that surrounds them: no safe level of exposure. But what happens when white cloud that disappears? Not only is a bad smell in hair or clothes.
The residual cigarette smoke can also cause cancer. A new study, published in ‘Proceedings of the National Academy of Sciences’ ( ‘PNAS’), warning of what he calls “third-hand smoke”, ie, “residual [...] that nicotine has been absorbed by certain areas. It seems that it reacts with nitrous acid present in the environment and, as a result of this, form a kind of nitrosamines which are carcinogens.

Factors of Lung Cancer
This cancer is one that takes more lives annually and affects people 40 and older. Since 85% of those who suffer are smokers, snuff is the major risk factor for developing it. Only one of every eight people who suffer are not smokers.
There are also other substances such as asbestos, uranium or radon is a colorless, odorless gas that builds up in homes and comes from the stoves, which are also risk factors for lung cancer.
Other risk factors include industrial pollution, smoke from factories or cars or hormonal factors of the person that make it more susceptible to developing it. A risk factor can also be the presence of scars in the lung, caused by surgery, bullets or knives.
Lung Cancer Risk Factors
Researchers have discovered several causes of lung cancer and most are related to the use of snuff.
Cigarettes. Cigarette smoking causes lung cancer. Harmful substances, called carcinogens in snuff, damage cells in the lungs. Over time, damaged cells may become cancerous. The probability that a smoker will develop lung cancer is affected by the age at which smoking began, by the time the person has smoked, the number of cigarettes smoked per day and the force with which the smoker inhales. Quitting smoking greatly reduces a person’s risk of developing lung cancer.
Cigars and pipes. People who smoke cigars and pipes have a higher risk of lung cancer than nonsmokers. The number of years a person smokes, the number of pipes or cigars smoked per day and the force with which the person inhales all affect the risk of developing lung cancer. Even the smoking of cigars and pipe do not inhale are at increased risk of lung cancer, mouth and other types.
Snuff smoke in the environment. The possibility of developing lung cancer increases with exposure to tobacco snuff in the air: the smoke in the air when someone else is smoking. The snuff smoke exposure in the environment is called second hand smoking or passive smoking or involuntary.
Radon. Radon is an invisible radioactive gas, odorless and tasteless, that occurs naturally in soil and rocks. It can damage the lungs, which can lead to lung cancer. People who work in mines may be exposed to radon and, in some parts of the country, radon in homes also. Smoking increases the risk of further lung cancer in people who already have the risk from exposure to radon. A kit for home use to measure radon levels in homes is for sale at most hardware stores. The home test for radon is relatively easy to use and not expensive. After correcting the problem of radon, the risk disappears completely.
Risk Factors of Lung Cancer
Nicotine potentiates the carcinogenic effect of other substances from smoke snuff and the effects of carcinogens in the environment.
Nicotine acts on the mechanism of apoptosis, or cell death, preventing the cells to commit suicide. When it comes to cancer cells does the same thing which causes or encourages the formation of lung cancer.
In addition to snuff, there are other substances mentioned above which are listed now:
Asbestos: people who work with asbestos are seven times more likely to develop cancer than those who do not maintain contact with it. These people have a type of cancer called mesothelioma, which occurs in the pleura. In recent years, governments have banned the use of this material for commercial and industrial products. When combined with asbestos exposure to smoking, it increases their chances of getting cancer from 50 to 90 times.
Cancer-causing agents in the workplace: an occupational risk group are the miners. They work with materials that, when inhaled, can damage your lungs. Such substances are radioactive minerals such as uranium, and workers exposed to chemicals such as arsenic, vinyl chloride, nickel chromates, coal based products, mustard gas and chloromethyl ethers. People working in these conditions should be careful to avoid exposure to these agents.
