Two weeks ago, he began coughing up a bloody sputum ("hemoptysis"). In the past week he's become increasingly short of breath. A routine chest X-ray revealed two silver dollar-sized opacities on the right side of the carina. Bronchoscopic examination revealed a tumor that was nearly occluding the right mainstem bronchus. A bronchial biopsy revealed the diagnosis: bronchogenic carcinoma. 1. Define the terms and describe where in the body each term is: a. bronchogenic carcinoma; b. hemoptysis, opacities, d. carina a bronchogenic carcinoma: b. hemoptysis: c. opacities: d. carina: 2. Most cancers arise from epithelial tissue. Why do you suppose this is?Explanation / Answer
1. a) Bronchogenic carcinoma : A number of benign and malignant tumours occur in the lungs but the primary lung cancer,commnly termed bronchogenic carcinoma.It is the most common(95% of all primary) lung tumours.The lung is also the commonest site for metastasis from carcinomas and sarcomas.The term bronchogenic carcinoma is commonly used for cancer of the lung which includes carcinomas arising from respiratory epithelium lining the bronchi,bronchioles and alveoli.
b) Hemoptysis: It is the coughing of blood or blood stained mucous frm larynx,trachea,bronchi or lungs.This can occur due to tuberculsis,lung cancers,bronchitis,pneumonia etc.
c) Opacities: The quality or state of a body that makes it impervious to the rays of light.The relative capacity of matter obstruct by the absorption ofr reflection the transmission of radiant energy.eg.x rays,infrared etc.
d) Carina: The carina is found at the base of the trachea and it is formed as the main bronchi divide into right and left branches.It is usually placed at the t4 plane at the level of sternal angle..
2. About 90% of human cancers arises in epithelial tissues.Certain organs like intestine,skin,the epithelial layers renew continously throughout the life.By renewing the tissues the cancers rises sharply with age.childhood cancers concentrate in tissues that divide rapidly early in life but relatively little later in life.
90% of cancers arises as carcinomas in epithelial tissues.The epithelium may be external surface of an organ or internal surface of bladder,prostate,breast etc.
