Bronchogenic carcinoma is any type or subtype of lung cancer. The term was once used to describe only certain lung cancers that began in the bronchi and bronchioles , the passageways to the lungs. However, today it refers to any type. Lung and bronchus cancers are common, accounting for about 13 percent of new cancer cases in the United States. These are some of the most common symptoms of lung cancer:. Anybody can get lung cancer.

It begins when cells in the lung start to mutate. Instead of dying off as they should, the abnormal cells continue to reproduce and form tumors. The most common cause is smoking, which is responsible for about 90 percent of lung cancer cases.

Quitting smoking can lower your risk. Exposure to secondhand smoke can also raise the risk of developing lung cancer. The second most common cause is exposure to radon , a radioactive gas that can come up through soil and into buildings. Lung cancer is more common in men, especially African American men, than in women. If you have symptoms of lung cancer, there are several tests you doctor might use to help with the diagnosis. If cancer is detected, the pathologist will also be able to identify which type of lung cancer it is.

Then the cancer can be staged. This may require additional testing such as:. Staging helps guide treatment and provide more information on what you can expect. Treatment for lung cancer varies according to the specific type, stage, and your overall health. You may need a combination of treatments, which can include:. When cancer is confined to the lungs, surgery may be an option.

If you have a small tumor, that small section of lung, plus a margin around it, can be removed. A pneumonectomy is surgery to remove an entire lung. It is possible to live with one lung. Chemotherapy is a systemic treatment.

These powerful drugs can destroy cancer cells throughout the body. Some chemotherapy drugs are given intravenously and some can be taken orally. Treatment can last several weeks to many months. Chemotherapy is sometimes used to shrink tumors before surgery or to destroy any cancer cells remaining after surgery.

Radiation uses high-energy beams to target and destroy cancer cells in a specific area of the body. Therapy can involve daily treatment for several weeks. It can be used to help shrink tumors prior to surgery or to target cancer cells left behind after surgery. Radiosurgery is a more intense type of radiation treatment that takes fewer sessions. This may be an option if you are not able to have surgery.

Targeted drugs are those that work only for certain genetic mutations or specific types of lung cancer. These treatments may be used for advanced or recurrent lung cancer. The goal of supportive care is to ease symptoms of lung cancer as well as side effects of treatment. Supportive care, also called palliative care , is used to improve overall quality of life. You can have treatment for the cancer and supportive care at the same time.

These are only general figures for all types of lung cancer. Your doctor will be able to provide more information based on details specific to you. Here are some things you may want to discuss:. You might also want to consider joining a lung cancer support group. Here are few ways to find the right one for you:.

Bronchogenic Carcinoma

Adenocarcinoma of the lung is the most common histologic type of lung cancer. Grouped under the non-small cell carcinomas of the lung , it is a malignant tumor with glandular differentiation or mucin production expressing in different patterns and degrees of differentiation. This article brings a broad view over lung adenocarcinoma, for further details on each subtype, please refer to the specific articles listed below. Early symptoms are fatigue with mild dyspnea followed by a chronic cough and hemoptysis at a later stage. Lung adenocarcinoma is primarily categorized on the basis of histopathologic evaluation, although testing for genetic mutations e. Often it is impossible to radiographically distinguish between other histological lung cancer types.

This article will broadly discuss all the histological subtypes as a group, focusing on their common aspects and for further details please refer to the specific articles on each subtype described below. Lung cancer is a leading type of cancer, equal in prevalence with breast cancer Cough and dyspnea are rather non-specific symptoms that are common amongst those with lung cancer. Central tumors may result in hemoptysis and peripheral lesions with pleuritic chest pain.

Background: We prospectively analyzed the postoperative morbidity, mortality rate, and risk factors in patients who underwent thoracotomy for bronchogenic carcinoma. Methods: Patients were categorized by postsurgical tumor stage: I, patients Two hundred ninety-four patients The importance of the factors that influence the morbidity and mortality rates was calculated from their relative risks.

The problem of the functional tolerance to pneumo-nectomy is evaluated in the present study by means of differential quantification of pulmonary perfusion by radioisotopic studies and calculation of predicted postoperative FEV 1. Using already described techniques, in a series of patients with bronchogenic carcinoma pros-pectively undergoing a protocol study from to , inoperability was decided on the basis of a calculated postoperative FEV 1 of less than cc. In our experience, the correlation between the FEV 1 as calculated by this technique and the real postoperative values in high r In 14 pneumonectomies in patients with real postoperative FEV 1 of less than cc exceeding the above mentioned criteria , 1 patient died in the imme-diate postoperative period 7. This rate of postoperative mortality is similar to that seen in populations undergoing pneumonectomy for bronchogenic carcinoma and not being selected on the basis of functional criteria..
