Lung cancer is one of the most common types of malignancy, after skin cancer and breast cancer in women and prostate cancer in men, one of the most common causes of death.
This type of cancer is the highest percentage of deaths resulting from the disease, so the World Health Organization has assigned the month of November each year to raise awareness about the dangers and, like other cancers, the disease occurs at the level of genes cell phones and divides and multiplies in an irreparable and abnormal way.
Tumor cells are abnormal, which means they do not work in their position, so the tissue is not healthy lung, they multiply one another by taking different forms and can infect surrounding tissues of natural origin and carcinogen.
And it can spread to the lungs, and thus decrease the lung's ability to play its role in providing oxygen to the body and in the disposal of carbon dioxide.
In this topic, we address lung cancer in detail, with a description of the causes and causes of the disease, the symptoms that appear and the methods of prevention and treatment used and modern to cure the disease.
The mechanism of cancer formation
The cells of the human body are always renewed, the old cells die and are replaced by new cells. The process of substitution and regeneration in the human body is performed in a precise, harmonious and natural way.
The rate of formation of new cells sometimes exceeds the required number and increases in a crazy form of a mass that pushes around normal cells, and therefore the tumor is benign.
Proliferating cells move abnormally to other tissues near or far from where they appear for the first time, and begin to destroy the natural cells to replace them, which is called cancer.
Cancer is a disease at the level of the person's primary building, the cell, which is multiplied by division. Cancer infects its genes with madness. The process of division is accelerated uncontrollably, and its spread is not limited or transmitted. to nearby or non-adjacent areas of the human body.
Cancer affects all ages up to the embryos in the mother's stomach, although the risk of infection increases with age and the probability of survival increases significantly with children. Cancer affects all parts of the body from bones to organs , to tissues, blood and skin.
The types of lung cancer are different: there are two main types: the first is the small cell lung cancer, also called oocyte tumor, because the tumor takes the form of oats.
Cancer cells grow more slowly in this type, in 80% of people with lung cancer, and the other species that differ from many types are non-small cell lung cancer, which is found in 20% of lung cancer patients.
Cells of this type grow faster and attack the normal cells more aggressively: each of these species has its own way of spreading, as well as a medical treatment: a scan under the microscope reveals the quality of lung cancer in the patient's body.
The upper lung is produced by the shoulder, a relatively large type of non-small cell lung cancer, called Borm Bancost or Bancost syndrome, which takes its name from the American radiologist Henry Bancost, who observed four of his patients in 1924.
This tumor is characterized by the transition to the surrounding lung cells from the ribs and the rib cage. The tumor spreads and grows, pressing the brachial nerve plexus of a nerve network that moves the signals from the spine to the shoulder, arm and hand. Extend at your fingertips.
The muscles of the hand are afflicted by dysentery with pain in the back, neck and chest, and a sibilant breath from the lung due to the narrowing of the airways.
It is not the only type
Approximately 35% of patients with Bancost's tumor survive for five years, if they mix chemotherapy and surgery, and up to 44% if the disease is discovered before it reaches the mid-lymph nodes, the region of the middle-thoracic cavity.
The Bancost tumor causes Horner's syndrome, which occurs due to damage to a group of nerves, resulting in partial appearance of the eyelids and a slow enlargement of the pupil, and also the release of sweat from the face, trunk and arms.
Bancost's tumor is not the only type of non-small cell lung cancer, it is also a carcinoma of lung cells, glandular lung carcinoma and large cell lung cancer.
Non-small cell lung cancer occurs in several stages, starting from the zero stage, when the tumor is small and does not appear in the radiation, but the tumor cells appear in the analysis as a sputum sample when analyzed in a laboratory doctor.
The tumor cells extend into the lining of the inner lung followed by access to the deep cells of the lung, called the first stage of the tumor, then in the second stage the malignant tumor extends to the neighboring lymph nodes.
Malignant tumor cells then begin to spread to nearby and near organs, such as the large blood vessels, the diaphragm or the chest wall, the third stage of the disease.
Tumors and clusters of malignant cells are present in the fourth cancer stage in other parts of the body, such as the second lung, the brain, the bone, the liver or the adrenal gland.
The small cell lung cancer is divided into two stages, only in the limited stage of the infected lung and its adjacent cells, while in the second stage the ventricle expands outside the infected lung and is directed towards the thoracic tissue and the distant organs .
Smoking ruins people
Cigarette smoking causes 90% of lung cancer infections and this gives us an idea of the cause of cellular mutation: it is known that the smoker's lung gradually loses its pink color and is blackened by the color of the burnt tobacco .
This color means damage to the bronchial tissue inside the lung and the possible carcinogenesis of the cells. Cigarette smoke contains radon, a naturally occurring carcinotropic isotope in cells. Nicotine is also indicated to inhibit the response of the immune system to the malignant transformation of cells.
The risk of lung cancer surpasses those who sit with them and inhale their cigarette smoke, which is known as passive smoking.
Working in places with substances such as arsenic, nickel, chromium, tar, asbestos and radon increases the risk of lung cancer.
Immunosuppression, either as a result of acquired immunodeficiency syndrome (HIV) or inhibitors of the immune system, increases the chances of lung cancer.
Recent studies have suggested that a relative of first degree or a brother or sister of lung cancer increases the risk of infection.
The patient presents a variety of symptoms, but unfortunately they do not become visible until several years after the onset of the primary tumor and may only appear clearly in phase 4 with the spread of the disease out of the lungs.
Some symptoms of lung cancer are similar to many respiratory diseases, but they are more serious in the form of severe cough and may be accompanied by a blood exit and shortness of breath and pain in the chest, shoulder or back is not linked to cough and sputum color.
The patient's voice becomes hoarse, with a hissing sound and pneumonia and repeated bronchitis.
The doctor diagnoses the disease by radiography of the patient, where the tumors appear, then the CT scan of the lung followed by a sample of the lung through a dedicated syringe, inserted vertically on the chest to obtain a sample of malignant lung cells and sent to the laboratory to determine with precision the type of tumor.
Lung cancer is more likely to escape if the disease is diagnosed early, but it is difficult to see symptoms until later, so current smokers or former smokers should note any symptoms related to the chest and respiratory system.
He tells the doctor, because early diagnosis increases survival and periodic monitoring of the lung contributes to early detection.
The treatment method varies with the type and spread of cancer, but includes chemotherapy, surgery, radiation therapy and phototherapy with painkillers, medical assistance and social and psychological support.
Statistics show that lung cancer is not before age 45, and it is rare before reaching this age, and also shows that lung cancer is the number one cancer death, and has been the most common cancer for decades. .
Lung cancer kills about 1.7 million people each year, with about 90% of smokers, 87% of all smokers and at least 3% of them are passive smokers, who smoke other people's cigarettes .
It is useful, which can reduce the risk of lung cancer, exercise and maintain a healthy body, and these measures can reduce the incidence by about 20%.
