Lung Cancer Development

Development of Lung cancer

John was 29 years old when he was diagnosed with early-stage lung cancer. He had never smoked cigarettes in his life. John began to experience several symptoms and noticed that his voice was becoming weak. When John reached home, and he started searching for any information related to cancer in which he had been diagnosed. Additionally he had terrible torment in his upper right half of his back.

After that, he went to Victoria General Hospital, one of the biggest hospitals in the country, where he met doctor Bilal. Doctor Bilal told John was curious about what stage of cancer

Lung cancer is thought to start as areas of pre-cancerous cells mutates in the lungs. The first change happens in the genes of the cells themselves and this change may cause them to grow faster. The cells may look abnormal if seen under a microscope, but at this point they do not form a mass or tumor. They cannot be seen on an x-ray and they do not cause any symptoms. Over time, these pre-cancerous changes in the cells may progress to true cancer. As cancer develops, the cancer cells may make chemicals that cause new blood vessels to form nearby. These new blood vessels nourish the cancer cells, which can keep growing and form a tumor large enough to be seen on imaging tests such as x-rays. At some point, cells from cancer may break away from the original tumor and spread (metastasize) to other parts of the body. Lung cancer is often a life-threatening disease because it tends to spread in this way even before it can be detected on an imaging test like a chest
