Akciğer Kanserinde Radyoloji

Akciğer kanseri kadın ve erkeklerde kansere bağlı ölümlerin en sık nedenidir. Erkeklerde kadınlara göre daha sık görülmekte olup erkek-kadın oranı 1.5:1'dir. Akciğer kanseri riskini artıran epidemiyolojik faktörlerin başında sigara gelmektedir. Bu risk sigaraya erken yaşta başlama, içilen sigara sayısının fazlalığı ve inhalasyonun derinliği ile artmaktadır. Sigara kullanmayan akciğer kanserli olguların ise %25'inde pasif olarak sigara dumanına maruz kalma vardır. Mesleki olarak asbest, arsenik, nikel, berilyum, mustard gazı gibi maddelere maruz kalmak da riski artırmaktadır. Bu maddeler içerisinde asbest maruziyeti en iyi tanımlanmış risk faktörüdür. Ayrıca ileri yaş, difüz pulmoner fibrozis, kronik obstrüktif akciğer hastalığı (KOAH) ve genetik yatkınlık da akciğer kanseri riskini artıran faktörlerdir.

Diagnostic Imaging of Lung Cancer

Lung cancer is the most common cause of cancer related death in men and women. It is frequently seen among men than in women and male-female ratio is 1.5:1. Common epidemiological factors that increase risk of lung cancer is smoking. Early age to start smoking, high number of smoking cigarettes per a day and depth of inhalation increase risk of lung cancer. 25% of patients with lung cancer are nonsmokers that passively exposed to cigarette smoke. Occupational exposure to substances such as asbestos, arsenic, nickel, beryllium, mustard gas increases the risk of lung cancer. The well defined risk factor is exposure to asbestos. In addition advanced age, diffuse pulmonary fibrosis, chronic obstructive pulmonary disease (COPD) and genetic predisposition are the risk factors that increases lung cancer.
