It’s a change in arrangement of genes. It’s the reaction of adding or deleting single nucleotide to the DNA, replacing a base with another that leads to changing it to the amino acid. Other types of mutation can be large pieces of chromosomes instead of single nucleotide for examples erasing multiple nucleotides from single chromosome that late attract the chromosome again. The majority of the time mutations are created by environmental factors, like smoking cigarettes that lead to lung cancer. After the mutations, the cancerous cell can still perform like a normal cell and that is because it’s precancerous. Cancerous lung cells and their cell division guide to the ineffectiveness in the function of the lung. Metastasis is the process cancerous cell spread from the lung to other areas in the body or organs. Cancerous cell come in all sizes, small cancerous cells tendency to percolate to the brain, in order for this to be stopped fast, the brain is radiated with prophylactic cranial. The majority of the harmful chemicals inside our body are turned into harmless chemicals and that process is call “detoxification enzymes” these cleaner like proteins can sometimes be harmed by define chemicals in tobacco especially …show more content…
The relationship between lung cancer in the aftermath of WW1 is when the number of lung cancer patients increased. The cause and effect from that early research is copied in many there sorts of research. Studies have shown that smoking is the number one reason that causes the disease. Cigarettes are made up of toxic chemicals such as nicotine and benzene that harm our DNA by altering different types of mutations that will result in the formation of cancerous cells that finally take us to uncontrolled cell growth. There are several symptoms for lung cancer that take place in the chest, short breath, coughing, asthma and pain. A person with the disease may also have other symptoms that can affect the function of other part of the body that is due to the spreading of the infection by metastasis and the symptoms can be like pain of joint, loss of appetite, and internal bleeding. The early stages of lung cancer can be controlled and treated by chemotherapy where the patient with cancer is given drugs that contain unique chemicals to help shrink the tumor or eliminate the cancerous cells but just like with other drugs there are side effects that may cause the loss of hair. Another treatment is radiotherapy and that’s where high energy radiation removes the cancerous cells. In the advance stages of cancer patients are given drugs like tarceva to prevent the EGFR to signal the reproduction of cancerous cell and to stop the
