Lung Cancer

Lung cancer is cancer that starts in the lungs. The lungs are located in the chest. When we breathe, air goes through our nose, down our windpipe, and into the lungs, where it spreads through tubes called bronchi. Most lung cancer begins in the cells that line these tubes.

There are two main types of lung cancer:
  1. Non-small cell lung cancer (NSCLC) is the most common type of lung cancer.
  2. Small cell lung cancer makes up about 20% of all lung cancer cases.
If the lung cancer is made up of both types, it is called mixed small cell/large cell cancer. And if the cancer started somewhere else in the body and spread to the lungs, it is called metastatic cancer to the lung.

Symptoms depend on the type of cancer you have, but may include:
  • Chest pain
  • Cough that doesn't go away
  • Coughing up blood
  • Fatigue
  • Losing weight without trying
  • Loss of appetite
  • Shortness of breath
  • Wheezing

Health Tip of the Day

Eliminate "White Foods" from Your Diet. White flour, white sugar and other processed foods are not only devoid of vitamins and minerals, but they’ve also been stripped of their natural fiber. As a result, they rapidly drive up blood sugar levels, which contributes to weight gain, diabetes and a host of other health problems. Avoid breads and baked goods made with white flour, sugar-laden sodas and snack foods. Instead, focus on eating fiber rich fruits, vegetables, legumes and whole grains.

Human Body

The human body is divided into various regions or parts. Following are the parts:
  1. Head: Head consists of skull and face. Head houses the brain while the face is specially designed to accommodate the eyes, mouth and nose. Head is covered by a soft tissue known as scalp with the characteristic hairs.
  2. Neck: Neck is the narrow part of the body which connects head to thorax.
  3. Thorax: It is the part of the body which lies between neck and abdomen. It is also known as chest. It houses the two vital organs of human body which are the heart and lungs.
  4. Abdomen and pelvis: This region lies below thorax. It contains organs of digestive system, urinary and genital system. The area present between upper parts of two thighs is known as perineum.
  5. Upper limbs: A pair of upper limbs (Arms) is attached at the upper end of trunk of body, one on each side. Each upper limb consists of shoulder region, scapular region, arm, forearm and hand. Upper limb is meant to manipulate external environment e.g., grasping, moving, throwing, catching, screwing etc.
  6. Lower limbs: A pair of lower limbs (legs) is attached at the lower end of trunk of body, one on each side. Each lower limb consists of hip and buttocks, thigh, leg, ankle, heel, foot and toes. Lower limb is meant for locomotion.

Telemedicine is a rapidly developing application of clinical medicine where medical information is transferred through the phone or the Internet and sometimes other networks for the purpose of consulting, and sometimes remote medical procedures or examinations. Telemedicine can be simplly defined as two health professionals discussing a case over the telephone, or as complex as using satellite technology and video-conferencing equipment to conduct a real-time consultation between medical specialists in two different countries. Telemedicine generally refers to the use of communications and information technologies for the delivery of clinical care.

Care at a distance is an old practice which was often conducted via post. There has been a long and successful history of in absentia health care which, thanks to modern communication technology, has evolved into what we know as modern telemedicine. In its early manifestations, African villagers used smoke signals to warn people to stay away from the village in case of serious disease. In the early 1900s, people living in remote areas in Australia used two-way radios, powered by a dynamo driven by a set of bicycle pedals, to communicate with the Royal Flying Doctor Service of Australia.

The terms e-health and telehealth are at times wrongly interchanged with telemedicine. Like the terms "medicine" and "health care", telemedicine often refers only to the provision of clinical services while the term telehealth can refer to clinical and non-clinical services such as medical education, administration, and research.
