Carcinoma Cause Lung Cancer

What are lung cancers? Lung cancers are the abnormal cells which grow in uncontrolled manner in one or both lungs. They do not function as normal lung cells and do not develop into healthy lung tissue. The abnormal cells can grow, form tumours and interfere with the normal functions of the lung (Lungcancer.org, 2015). Lung cancers can be divided into two major types, namely non-small cell lung cancers (NSCLC) and small cell lung cancers (SCLC). NSCLC can be further classified into three main subtypes, namely adenocarcinoma, squamous-cell carcinoma and large-cell carcinoma (Longo & Harrison, 2012). Lung cancers can be diagnosed by chest X-ray, computerised tomography (CT) scan, positron emission tomography-computerised tomography (PET-CT) scan, bronchoscopy and biopsy (Nhs.uk, 2015). Unfortunately, lung cancers are often diagnosed at the later stages. This is due to the unrecognisable symptoms and warning signs at the earlier stages. NSCLC are often diagnosed at stage IV which accounts for 30-40% of cases whereas 60% of SCLC is diagnosed at stage IV. Lung cancer usually originates from the cells lining the bronchi, bronchioles and alveoli. Carcinogens especially tobacco smoke will alter the gene expression of the normal human lung cells, resulting in cell mutation. The proto-oncogenes will be converted to mutated form, oncogenes. Mutation leads to the decreased expression of the tumour suppressor genes. This results in uncontrolled cell proliferation, cell

C. Main Point 3: Depending on the stage of cancer, treatments can vary. I will be telling you a few important facts provided by NationalBreastCancer.org to know going into treatments and also the different types.

The phase of cancer at the point of diagnosis varies for different cancers. Therefore, staging is performed by means of various methods such as MRI (Magnetic resonance imaging), CT (Computed tomography), X-rays, blood tests and special surgery. The three main reasons why staging of cancer is performed are: it determines the depth of the disease, helps determine the treatment by the phase of the cancer and helps determine the patient's projection of treatment and survival.

Surgery is the most common method used to treat lung cancer followed by chemotherapy or radiation. Surgery can be used if the cancer is benign. Surgery removes the cancer inside the patient. Although surgery is the most popular method, the chance of the doctor being able to remove all of the cancer is highly unlikely. Since the cells are so small and there are thousands of them it is very difficult to remove every one. When a patient uses surgery to treat the cancer, the cancer has a good chance it can come back, because it only takes a few bad cells to spread and create a tumor.

Staging is the process of finding out how much cancer there is in the body and where it is located. It is how the doctor learns the stage of a person's cancer. Doctors use this information to plan treatment and to help predict a person's outlook (prognosis). Cancers with the same stage tend to have similar outlooks and are often treated the same way. The cancer stage is also a way for doctors to describe the extent of the cancer when they talk with each other about a person’s case.

Lung Cancer, like any other type of cancer, is the uncontrollable growth of cells in the lung tissue. The main causes that contribute to lung cancer include inhaling carcinogens (basically, smoking), exposure to ionizing radiation, viral infections and even air pollution. These factors basically damage the tissues lining the bronchi in the lung, leading the cancer to develop further (Vaporciyan & Nesbitt JC, 2000). Primary lung cancers that develop in the epithelial tissues of the lung are known as carcinomas and claim the top spot in terms of leading cancer-related death causes. As of 2004, lung cancer

Lung Cancer Staging is a way of describing a cancer, such as the size of the tumor and where it has spread. Staging is the most important tool doctors have to determine a

Staging is used to locate cancer and to see if it's affecting any parts of the body. Doctors use staging in order to understand what stage of lung cancer a patient has. Once the stage is determined doctors will figure out what she should be used to cure the cancer. Lung cancer is different in each person, and treatment works differently for each tumor. Stages are determined by the size of the tumor, the location of the tumor, and whether the cancer has spread throughout the body. The first stage is stage 0. This stage means that the cancer is in place and it has not moved through the body. The

Stage III: from when the tumor first appeared, has grown dramatically and continues to travel through the body.

The first treatment option is surgery. There are many different ways of getting the surgery. The first way is called Lobectomy. What they would do is cut 1 of the 5 lobes to get rid of the tumor. The 2nd option is called a wedge resection. They do this if you can't have one of your lobes removed. They just remove the tumor and not a whole lobe. The 3rd option is segmentectomy. This is another option if you can't have a lobe be removed. The fourth and last surgery option is called Pneumonectomy. If the tumor is in the middle of the lung, you can get the whole lung removed.

Stage 2 and Stage 3 cancer has invaded the chest (if large tumors are present its stage 3)

Cancer is the most significant cause of death for both men and women is measured to be the main cause of cancer decease worldwide, and it is complex to detect in its early stages because symptoms emerge only in the advanced stages causing the mortality rate to be the highest among all other types of cancer. More people die since of lung cancer than any other types of cancer such as breast, colon, and prostate cancers. There is major evidence indicating that the early detection of lung cancer will reduce mortality rate. The majority recent estimate according to the latest figures provided by world health organization indicates that around 7.6 million deaths worldwide each year because of this type of cancer. Furthermore, mortality from cancer

There are four stages of breast cancer. The Stage 0 is noninvasive breast cancer, that is, carcinoma in situ with no affected lymph nodes or metastasis. Stage zero is the most favorable. Now Stage 1 breast cancer is less than two centimeters in greatest dimension and is only in the breasts. In Stage 2, the cancer is no larger than two centimeters but it has spread to the lymph nodes under the arm. The

The stage of colorectal cancer describing where the cancer is located in the body. It likewise helps the specialist to decide how genuine the growth is and how best treat it. [1] The phase of a colorectal tumor depends on the consequences of biopsies, physical exams, and imaging tests (CT, X-ray examine, x-beams or PET output), which are depicted in Tests for Colorectal Growth and the aftereffects of surgery. Colorectal cancer has five stages such as stage 0, stage I, stage II, stage III, and stage IV.

American Lung Association (2015) has defined lung cancer as a growth of abnormal cells in the lungs without control, which
