Lung Cancer Symptoms
In 2019, it is estimated that there will be 228,150 new cases of lung cancer in the U.S., according to theAmerican Cancer Society. Although not the only cause, the most common cause for lung cancer is smoking. Many chronic smokers develop different types of lung cancer over a period of time.
Some of the first symptoms of lung cancer are weight loss and loss of appetite. As explained byCancerCare, the immune system produces proteins called cytokines to help fight the disease. Unfortunately, prolonged secretion of these proteins can lead to weight loss and decreased appetite.
Liver Cancer and Weight Loss
The liver is the organ in the body that makes enzymes and bile, which help you to digest fats, vitamins and other nutrients. When you have liver cancer the organ stops functioning properly and many symptoms can present such as yellowing of the skin, abdominal pain, nausea and fatigue, according to theAmerican Medical Association.
When the liver produces an abnormal amount of enzymes to digest food or the cancer from the liver has spread to the stomach, there can be a dramatic decrease in the amount of nutrients absorbed by your gastrointestinal tract. This decrease in food absorption can lead to significant weight loss.
