Reduction in body weight
There is an unintentional loss of body weight due to fewer intakes of nutrients. The cancerous growth in the various parts of the lungs disrupts the respiration process and the persistent coughing or pain in the chest cavity, making the person eat less or not eat at all. Cancer growing in the lung also makes the body unable to utilize all the nutrients from food. Moreover, the abnormal growth of cancerous cells in the lungs stimulates the body burn more calories than usual, and even in the resting state of the body, there is the breakdown of healthy tissues.
