Doctors use special machines to detect the severity of each stage. Treatments and cures differ in each individual case. Lung cancer is a huge problem because it is the leading cause of cancer death in both men and women (Microsoft, “Lung Cancer';). Both small cell and non-small cell lung cancer affect different types of cells in the lung and spread in different ways. Small cell lung cancer is limited to a section of the chest known as the hemithorax and regional lymph nodes (World Book, “Lung Cancer';).
What different types of lung cancers exist? - Non-small cell lung cancers (NSCLC) are classified together due to thier similar treatment and prognosis. However, specific types of NSCLCs affect different types of lung cells. They account for 85 to 95 percent of all lung cancer diagnosis. • Squamous cell carcinoma (epidermoid carcinoma) starts in the cells lining the airways of the lungs and is also found in the bronchus, towards the middle of the lungs.
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 die.
There are three main types of non-small cell lung cancer and they are squamous cell carcinoma, adenocarcinoma, and large cell carcinoma. Small cell cancer is the least common and it grows fairly rapid and it can easily spread to other organs in the body (Cavendish, p.946). Usually cells grow and divide at a specific pace that keeps the body working healthy but sometimes the cells start to divide at an uncontrollably pace. When the cells grow too much they make a tumor. The cells in this tumor are cancer cells and when the cancer cells are in the lungs, they eat away at the lungs, which leads to killing someone.
These two different origins of the cancer cause the treatments and symptoms to very in similarity, though Primary Lung Cancer is the main cause of lung cancer deaths worldwide. Lung Cancer can be divided additionally into types and stages of development to determine the severity of the disease, there are several types of lung cancer and four stages of development. The two major types of lung cancer include Non-Small Cell Lung Cancer (NSCLC) and Small Cell Lung Cancer (SCLC). According to the American Cancer Association, 85% of lung cancers are Non-Small Cell Lung Cancer, while Small Cell Lung Cancer occurs less frequently with the remaining 15% of lung cancers. However, there are several subtypes of NSCLC.
They are mutated and cannot be killed like normal. Once the known tumors become oversized, they take over and cause the lung or lungs not to do their jobs (Crosta). There is primary Lung Cancer and secondary. Primary lung cancer is treated differently than secondary because, primary starts in the lungs, while secondary starts somewhere else in the body, making its way to the lungs. Lung cancer is grouped in two categories ' which are non-small cell and small cell (Marks).
The most common cancer of the lungs is epidermoid. It is also known as squamous carcinoma because its cells look like a flat surface called a squamous cell. This cancer produces keratin, a substance found in skin and hair, which can be seen in a tumor. Squamous carcinoma is more common in smokers because it develops in the bronchi and spreads by invading local tissues, than to the lymph nodes and into the blood. Large - cell carcinoma is a tumor that is fairly larger than other types.
Metastasizing means to affect or spread elsewhere in the body from the original tumor site to another site on the body by transporting tiny cells by the lymph’s or blood. A skin tumor is benign, if the tumor spreads to the tissue it’s known as malignant or cancerous, and if the tumors affects healthy cells its known as malignant tumors. Most skin cancers affect people who are 50 or older and a growth begins to change the existing skin growth, then a sore form to be cancerous. For treatment to be able to happen it has the cancer must be in a treatable area, the type of cancer has to be treatable, depends on the stage of the cancer, the age of the person, and the overall health of the person. Melanoma is very rare cancer and is sometimes referred to as malignant melanoma.
Lungs cancer are divided into two types i.e. small cell carcinoma and non- small cell carcinoma. Both types have some molecular lesions similarities, while others are quite specific. The prevailing oncogenes that are frequently involved in lung cancer are c-MYC, KRAS, c-MET and c-KIT. And the most inactivated tumor suppressor genes are p53, RBI, p16(INK-4a) and multiple loci on chromosome 3p, where numerous tumor genes such as FHIT,RASFFIA and others genes which are yet to identified are present in the loci.
Brief Description: Lung cancer, as with all cancers, is an uncontrollable increase of cells. It happens within the lung tissue, but it could also go on to affect other nearby tissue and spread to further out than just the lungs. Cellular / Molecular Basis: Lung cancer has two types; small cell and non small cell. The two types can be identified by their appearance when looked at with a microscope. It usually affects the cells that are lined along air passages in the lungs.
