DCIS is reported to be more linked to breast cancer. The abnormal cells lining the breast duct if left untreated might lead to breast cancer. However it cannot lead to lung cancer.

Lung cancer biopsies are not only important but are also accurate. A chest X Ray may not give the details needed to determine the type or stage of cancer. A biopsy allows the cells from the area to be examined under a microscope allowing a better study of the problem.

Smoking is the prime cause of lung cancer. It is also caused by exposure to radon gas, which is naturally found in soil and rocks. Individuals exposed to harmful chemicals like vinyl chloride or nickel chromate also run the risk of developing lung cancer.

Lung cancer is a common disease amongst smokers. Non smokers who have been exposed to passive smoking are equally at risk. People living in industrial belts and exposed to toxins can also develop lung cancer.

Lung Cancer after much research was reported by the National Institutes of Health on July 26, 2004. They based their research on 52 first family generations who had some kind of cancer. Out of these 52, they found that 36 members have been affected in the two generations, with the five year survival rate at only 15%.

Lung cancer is one of the commonest form which can spread to the brain. However it depends on the type of original tumor. It will also depend on how long the original cancer tumor has been present in the body.

A total of only 15 % of non smokers get lung cancer. Smokers are at a much higher risk of attracting the disease. It has been reported that around 42% of smokers develop squamous cell lung cacrcinoma.

Cancer can cause the lungs of the patient to collapse. The cyst or tumor might burst. This consequently causes free air to accumulate outside the lungs thus leading to a collapse.

Tobacco smoking is the primary cause for developing lung cancer. It is also prevalent in people exposed to second hand smoke. Moreover, individuals who live in an area of industrial production of tobacco are also prone to getting the disease.

Lung cancer in most early stages cannot be detected unless with an X Ray. The X ray might show a small lump or lesion, which then needs to be further tested. In most cases, patients might feel shortness of breath, wheezing, cough with blood sputum and chest pain.
