Lung cancer is the uncontrolled growth of abnormal cells that start off in one or both of the lungs. The cells that are abnormal do not develop into healthier tissues, they instead develop into tumors. When these tumors get larger, the lungs ability to provide oxygen to the bloodstream is affected. Benign tumors are tumors that remain in one place.
Malignant tumors are tumors which are known to be the most dangerous. These can spread throughout the body through the bloodstream or the lymphatic system. When cancer spreads throughout the body, it is much harder to treat. Lung cancer have caused one million three hundred and seventy thousand deaths. Cancer is caused when cells grow and do not ...view middle of the document...
This can cause; a fever, fatigue, weight loss, pain in the joints, memory loss, swelling in face or neck, weakness, and blood clots.
How is lung cancer diagnosed? Extracting the cancer cells and viewing them under a microscope is the only absolute way to diagnose lung cancer. This procedure is called a biopsy. If the biopsy confirm that the patient has lung cancer then the pathologist will then determine if it’s a beg cancer cell or a small one. The oncologist then determines the stage of cancer by finding out how far it has spread throughout the body. Depending on the state of lung cancer you have depends on the treatment. So for instance, a small tumor that has not spread is stage one, notified as (T1).
• Stage 1 is when the tumor is found only in one lung and in no lymph nodes.
• Stage 2 is when the cancer has spread to the lymph nodes surrounding the infected lung.
• Stage 3a is when the cancer has spread to lymph nodes around the trachea, chest wall, and diaphragm, on the same side as the infected lung.
• Stage 3b is when the cancer has spread to lymph nodes on the other lung or in the neck.
• Stage 4 is when the cancer has spread throughout the rest of the body and other parts of the lungs.
Small cell lung cancer has two stages. These stages are, limited or extensive. In the limited stage, the tumor exists in one lung and in the nearby lymph nodes. In the extensive stage, the tumor has infected the other lung as well as the organs in the body. As these are no single treatment for cancer, most patients often receive a combination of the therapies and palliative...
