Lung Tumour is the abnormal growth of lung tissues that can significantly block the airways in the lung and can cause issues in breathing.  History “Lung cancer continues to be the leading cause of death in both men and women in the US, with over 158,900 deaths in 1999. Worldwide, lung cancer kills over 1 million people a year. Extensive prospective epidemiologic data clearly establish cigarette smoking as the major cause of lung cancer. It is estimated that about 90% of male lung cancer deaths and 75–80% of lung cancer deaths in the US are caused by smoking each year” (Hecht, 1999). Clearly, lung cancer is an important and widespread disease that constitutes a major public health problem. This was not always so. Some 150 years ago, it was an extremely rare disease. In 1878, malignant lung tumors represented only 1% of all cancers seen at autopsy in the Institute of Pathology of the University of Dresden in Germany. By 1918, the percentage had risen to almost 10% and by 1927 to more th

Epithelium, also known as ' Epithelial tissue' is one of the four basic types of animal tissues, the other four being connective tissue, muscle tissue and nerve tissue.

Conjunctivitis is an infection on the topmost layer of the eyes. The infection generally results in reddening of the infected eye and is contagious. History

Overview Myocardial Infraction, also commonly called as heart attack, is a medical condition where the coronary arteries gets blocked due to formation of plague. This usually results in the death of the heart tissues of the affected areas. The condition is usually treatable but in times may lead to death if not given proper medical attention. History The American College of Cardiology reports that the earliest documented case of coronary atherosclerosis – a build-up of plaque in the arteries that can cause a heart attack – was in an Egyptian princess who lived between 1580 and 1550 B.C. The study also found that heart diseases were more common in ancient times than previously speculated. Symptoms Symptoms include tightness or pain in the chest, neck, back or arms, as well as fatigue, lightheadedness, abnormal heartbeat and anxiety. Women are more likely to have atypical symptoms than men. Heart attack is generally gradual and if not given medical attention may cause serious irreparable

Overview Stroke is a medical condition in which a single or multiple of the blood vessels supplying oxygen rich blood to the brain gets blocked. This renders some part of the brain unfunctional for a period of time which may in rare instances lead to brain-death, in which tissues of the brain suffer irreparable damage. Stroke is also called CVA, cerebrovascular accident. History     Hippocrates, famously known as the "Father of Medicine" , first recognised stroke more than 2,400 years ago. He called the condition apoplexy, which is a Greek term that stands for “struck down by violence”.  Jacob Wepfer, a Swiss pathologist, discovered in the early 1600s that the blood supply was disrupted in the brains of those people who died from apoplexy. He soon came to the conclusion that deaths in most such cases was due to massive bleeding inside the brain. This was one of most significant findings that would lead modern medicine to find the treatment to such disorder. Symptoms Initial s
