What is Lung Cancer

Lung cancer

            Lung cancer, also known as lung carcinoma, is a malignant lung tumor characterized by uncontrolled cell growth in tissues of the lung. If left untreated, this growth can spread beyond the lung by the process of metastasis into nearby tissue or other parts of the body. Most cancers that start in the lung, known as primary lung cancers, are carcinomas. The two main types are small-cell lung carcinoma (SCLC) and non-small-cell lung carcinoma (NSCLC). The most common symptoms are coughing (including coughing up blood), weight loss, shortness of breath, and chest pains. 

A study of long-term outcomes in cancer patients found that nearly 1 in every 12  go on to develop other, unrelated cancers, especially lung cancer. According to researchers at the University of California in Los Angeles (UCLA), the findings point to the need for broader monitoring of cancer survivors than that now given. 

Cigarettes contain toxic chemicals including radioactivity and a record of containing coumarin. The term is "Toxic Tobacco Smoke" (TTS). These toxic substances impair the immune system. This combination makes cigarettes a risk factor in lung cancer.

 

During the nineteenth century, a number of physicians had observed TTS-induced lung disease, even lung cancer, incidents. Sort of hard to not observe it, eh?! Contrary to tobacco lobby disinformation to the public.
