Lung cancer is one of the more prevalent kind of cancer. Smoking is usually the culprit. Constant exposure to toxic waste, radiation and asbestos also build up threats of a lung disease.
Lung cancer is an ailment of unrestrained cell development in the lung tissues. This growth may lead to metastasis, spreading to the adjoining tissues and penetrating prematurely the lungs.
Lung cancer is the most popular cancer cause of death in men, and the second most common in women.
Frequent symptoms of lung cancer:
1. Continuous chest throbbing
2. Persistent coughs that become severe
3. Shortness of breath, puffing, or huskiness
4. Constant troubles with pneumonia or bronchitis
5. Coughing up blood
6. Inflammation of the neck and face
7. Loss of appetite or significant weight loss
Types of Lung Cancers:
A. Small-cell lung cancer occurs when malignant cells form in the lung tissues.
Small lung cancer has three different types, classified according to the forms of cells developing as cancer. These are:
1. Small cell carcinoma
2. Union of small cell and large cell carcinoma.
3. Joint small cell carcinoma.
These three kinds may contain many different types of cells. The cancer cells of all types may grow and multiply in different ways.
Stages of Small Cell Lung Cancer
Limited stage – cancer starts in the lung tissues, and in the adjacent lymph nodes. Lymph nodes are tiny, bean-shaped structures near the lungs.
Extensive Stage – cancer has propagated beyond the lungs to other parts of the body.
B. Large-cell lung cancer is a disease in which malignant cells form in the tissues of the lungs.
Five types of large-cell lung cancer
The five types of large-cell lung cancer have differing varieties of cancer cells. The cancer cells of each category produce and multiply in unusual effects:
1. Squamous cell carcinoma – Cancer starts in the squamous cells, thin flat cells that appear like fish scales. It’s called epidermoid carcinoma.
2. Large cell carcinoma – Cancer in which the cells are big and seem to be irregular when examined under a microscope.
3. Adenosquamous carcinoma – Cancer that begins in cells. Cancer cells appear to be firm when inspected under a microscope.
4. Adenocarcinoma – Cancer that begins in groups in glandular assets.
5. Undifferentiated carcinoma – Cancer cells that do not seem to be normal. They spread fast.
1. Surgery – Surgery is the ideal medication for lung cancer. The body is normally opened up for the lungs to be treated directly.
2. Radiation is a common treatment for lung cancer. Radiation therapy utilizes high-energy rays to destroy cancer cells. It distresses cells only in the treated area.
a. External radiation is the most common radiation treatment for people with lung cancer. Radiation comes from a huge apparatus outside your body. Mainly people go to the hospital or clinic for treatment. Treatments are typically 5 days a week for more than a few weeks.
b. Internal radiation is rare. Radiation is released from a seed, wire, or another device, to the body.
Treatment of Large-Cell Lung Cancer:
* Chemotherapy – This is cancer treatment making use of drugs to prevent the increase of cancer cells. Drugs are either taken by mouth or injected in the veins and muscles to destroy cancer cells. These drugs go into the bloodstream to treat cancer cells in the body. When chemotherapy is placed straight in the spinal column, an organ, or a body cavity like the abdomen, these drugs generally distress cancer cells in those parts.
* Laser therapy – Laser is used to destroy cancer cells.
