Smoking And Cancer

Smoking harms almost every organ of the body and diminishes a personís overall health. The chances of smokers being affected by cancer are very high.

Several studies have shown that the various carcinogens in the cigarette smoke cause cancer. Cancers are most likely to occur in organs like lungs and oral cavity, which come into direct, contact with smoke.

Cigarette smoke contains about 4,000 chemical agents, out of which 70 substances are carcinogenic. Some of these harmful substances are - carbon monoxide, tar, arsenic, cyanide, benzene, formaldehyde, methanol, acetylene, ammonia, lead etc.

When the carcinogens in cigarette smoke are absorbed and spread through the human body, smoking causes cancer at various distant sites. Smoking causes many types of cancer, including cancers of the lung, esophagus, larynx, mouth, throat, kidney, liver, bladder, pancreas, stomach, cervix, bowel and also acute myeloid leukemia.

The risk of developing cancer is related to -

Number of cigarettes smoked
Duration of smoking
Age at which smoking is started
The type of cigarettes smoked

Smoking can affect various parts of the body. First of all, cigarettes contain carcinogens, which are substances that cause cancer. The cancer that cigarettes are going to lead to is most very likely lung cancer. The organs that are going to be affected are for sure lungs. Lung cancer contains a process known as metastasis, which will spread the effect to other parts of the body. Hi, I am 13 years old and I really enjoy medical studies.

Why is your/the page - about the contents of a cigarette even up? It's a waste of time. People are searching for the WHOLE THING, not just some micro entry! Phooey. Thanks for the waste of time. Lay it all out! The full and complete list of ALL the dangerous poisonous stuff or at least give a link to a page that DOES have it all. At this time, your page of cigarette contents is a pretender, an anemic version of what most are looking for.

The cells of all living organisms normally divide and grow in a controlled manner. Cancer results when this control process is lost. A lump or tumour, known as the primary tumour can grow locally or spread to produce secondary tumours somewhere else in the body. This spreading process is called metastasis.
