Imagine going outside and not being able to smell the fresh air. Now imagine not being able to smell your favourite scent. Those are just some of the effects of lung cancer. There are different types of cancer in the world today.
They range from throat cancer, to colon cancer, to even breast cancer. The number one killer, however, of both men and women is lung cancer. The number one cause of lung cancer is smoking. 87% of lung cancer cases are caused by smoking.
Our body is made up of cells, which is the body’s basic unit of life. Usually cells grow, divide, and produce more cells as needed to keep the body healthy. Sometimes this process can happen too rapidly and the body produces more cells than needed. The mass of unneeded cells form a growth called a tumor. Not all tumors are detrimental to one’s health. Tumors can either be benign or malignant.
Benign tumors are not cancerous. They can often be removed surgically. Once a benign tumor is removed, it does not return. They are rarely a threat to life. Malignant tumors, on the other hand are cancerous. These cancerous cells can break away and break apart the surrounding tissues. These cells can enter the blood stream and invade other parts of the body also.
