Cancer may increase gradually as an outcome of a number of factors which may be associated to the lifestyle, heredity and environment of a person. The researchers and scientists have found out that there are a lot of factors that increase the probability of getting a disease called cancer. They calculate approximately that about 90 percent of each and every type of cancer is associated to the consumption of tobacco foodstuffs, and the other 10 percent are connected to what we drink and eat regularly. Some factors may be connected with the harmful radiation or the exposure to cancer-causing mediators (carcinogens) which might be present in the workplace and may be in the environment. A number of people are more susceptible than the others to these factors, which can be the reason behind the occurrence of cancer.
A lot of these factors can be evaded, while some of them like the factor of inheritance are unavoidable. It is very useful to be conscious about these factors, on the other hand it is moreover imperative to keep in mind that each and every one of these factors which may cause cancer in reality doesn't cause it. The people who are at risk can defend themselves by avoiding these factors wherever and whenever possible and by receiving regular check-ups with the intention that, if at all cancer increases, it could be located at an early stage.
The two factors which are extremely lethal in causing the various kinds of cancer are the consumption of tobacco and the second one is smoking. Smoking is to be blamed for at least half of all the deaths that are caused due to cancer. Moreover, smoking alone accounts for at least 90 percent of all the deaths which are caused due to the lung cancer. If you are a chain smoker, then the risk of getting the lung cancer is very high, and this risk is exaggerated by the amount and the brand of cigarettes that you smoke.
In addition to the lung cancer, the chain smokers are most likely to get a number of other forms of cancer as well (for instance the cancers of the esophagus, larynx, pancreas, kidney, bladder and cervix and the oral cancer as well). The threat of cancer starts to reduce when a chain smoker stops smoking, and the threat continues to reduce slowly but surely each day after leaving the habit of smoking.
