Cancer is a generic term for many diseases that can affect any organ or part of the body. One defining feature is the rapid creation and multiplication of abnormal cells that grow beyond their usual boundaries, causing them to invade adjoining parts and spread to other organs. Widespread metastases (the process of spreading of cancer cells) are the primary cause of death on account of cancer. Cancer results from the transformation of normal cells into tumour cells through a long process that grows from a lesion to a malignant tumour. Usage of tobacco, unhealthy diet, alcohol consumption, physical inactivity and air pollution are external factors that can interact with a person’s genetic composition and cause chronic illnesses leading up to cancer. This article will help you in knowing about types and causes of cancer
Some of the most common type of cancer in the world, along with their causes and treatment, are posted on my publications, don’t forget to visit them:
Lung cancer is the most common cause of cancer deaths worldwide. It usually arises in cells lining the air passages in the lungs. Lung cancer is highly prone to spreading to other body parts through blood and lymphatic vessels. Both active and inactive smoking and tobacco consumption are the primary causes. These may result in shortness of breath, coughing up blood, unusual weight loss, headaches, and chest pain. Control of weight, a good diet and abandonment of tobacco intake can reduce the risk of lung cancer.
As mentioned above, tobacco usage and smoking can cause irreparable damage to the lungs. Cigarette smoke contains carcinogens that can multiply and become malignant tissues in the lungs.
Exposure to radon gas is another cause. It is generated from the breakdown of radioactive radium present in the Earth’s crust. In the U.S, radon is the second-most common cause of cancer and causes 21000 deaths each year.
Outdoor air pollutants released from burning fossil fuels are another contributor. Wood, charcoal, and cow-dung residue are hazardous to breathe.
What is the treatment for lung cancer :
The treatment of lung cancer depends on the size of the tumour, whether the cells are local or widespread, and the patient’s general condition. Surgery, chemotherapy, and radiation therapy may be used in isolation or combination, depending on these factors. Targeted therapies are done through drugs that target specific molecular targets in the tumour. They kill the cancer cells only, block their growth and prevent their spread to other body parts.
