Blood-laced mucus from the sinus or nose area can sometimes be misidentified as symptomatic of hemoptysis (such secretions can be a sign of nasal or sinus cancer, but also a sinus infection). Extensive non-respiratory injury can also cause one to cough up blood. Cardiac causes like congestive heart failure and mitral stenosis should be ruled ...
It’s also the leading cause of cancer death in both men and women. Lung cancer survival has not improved much in the last 50 years, according to Cancer Research UK, with less than one in 10 (9.5 ...
Being around tobacco smoke – called passive smoking – can also cause lung cancer. Living with a tobacco smoker increases one's risk of developing lung cancer by 24%. An estimated 17% of lung cancer cases in those who do not smoke are caused by high levels of environmental tobacco smoke. [68]
The Pancoast tumor was first described by Hare in 1838 as a "tumor involving certain nerves". [2] It was not until 1924 that the tumor was described in further detail, when Henry Pancoast, a radiologist from Philadelphia, published an article in which he reported and studied many cases of apical chest tumors that all shared the same radiographic findings and associated clinical symptoms, such ...
Her initial results, which she presented at a major cancer conference, showed that Asian women had a higher lung cancer detection rate than the original national trial — 1.5% versus 1%. “Based ...
A nosebleed, also known as epistaxis, is an instance of bleeding from the nose. [1] Blood can flow down into the stomach, and cause nausea and vomiting. [8] In more severe cases, blood may come out of both nostrils. [9] Rarely, bleeding may be so significant that low blood pressure occurs. [1]
Genetics can also play a role as a family history of lung cancer can contribute to an increased risk of developing the disease. [1] Furthermore, research has revealed specific chromosome regions associated with increased risks of developing lung cancer. [1] In general, DNA damage appears to be the primary underlying cause of cancer. [19]
Lung squamous-cell carcinoma is the second most common histologic type of lung cancer after adenocarcinoma, reaching 22.6% of all lung cancer cases as of 2012. [11] The relative incidence of the former has been steadily decreasing in favor of the latter due to the decreasing smoking rates in the last few years. [9]
