Signs and symptoms
The majority of patients who are diagnosed with lung cancer usually present with locally advanced or metastatic disease. Only about one third of patients have stage I disease when diagnosed. The symptoms that the patient exhibits usually reflect the extent of the cancers spread. Lung cancers that are discovered early may cause symptoms localized to the respiratory system. However, lung cancer that is advanced will cause patients to experience additional signs and symptoms secondary to the cancer spreading to other organ systems. In order of highest frequency, the most common signs of lung cancer include:
cough that does not go away or gets worse
weight loss
dyspnea (shortness of breath or difficulty breathing)
chest pain, which may be aggravated by deep breathing, coughing, or laughing
hemoptysis (coughing up blood or rust-colored phlegm)
bone pain
clubbing
fever
generally feeling tired or weak
superior vena cava obstruction- facial, neck, upper torso swelling. This is caused by compression of vasculature by the lung tumor that restricts blood return from the upper body. dysphagia (trouble swallowing or the sensation that something is caught in the throat) and hoarseness
new onset of wheezing without history of asthmaClinicians should have a high level of suspicion for lung cancer, especially in patients with a smoking history. Patients with recurring or unresolving lung infections (e.g. bronchitis and pneumonia) that are unresponsive to antibiotics should also be further evaluated for lung cancer. In nonsmokers, women and East Asians are more likely to present with symptoms of an underlying lung cancer at younger ages.
However, the conservative enucleation is the treatment of choice for most odontogenic cysts. The removed cyst must be evaluated by pathologist to confirm the diagnosis, and to rule out other neoplastic lesions with similar clinical or radiographic features (e.g., cystic or solid ameloblastoma, central mucoepidermoid carcinoma). There are cysts, e.g. buccal bifurcation cyst with self-resolation nature, in which close observation can be employed unless the cyst is infected and symptomatic. See also
