Cigarette smoking is the superior cause of cancer. Cigarette smoke consist of more than 3,800 distinctive chemicals, and more than 40 are carcinogenic (cancer causing). Allocation of the abstinence from food, particularly greasy foods and alcoholic liquid refreshment, also are connected to cancer. Skin disclosure to ultraviolet radiation in sunlight is the basic cause of melanoma, a skin cancer. Sexual behavior that relief expansion sexually conducted diseases is closely connected to cervical cancer in women.
Chemotherapy is a drug treatment that uses chemicals to kill cancer cells. The drugs are most often given through a vein, after that the chemotherapy chemicals travel throughout your body. It can also help people with bone cancer that has spread beyond the bone to other areas in the body. Radiation therapy is also an option. Radiation therapy uses high-powered beams of energy to kill cancer cells.
Among the many types of cancers, lung cancer is one of the most common diseases that smoking can cause. Inhaling cigarette smoke that is full of cancer-cause substances like carcinogens, which includes tar, causes lung cancer. Tar is brown, syrupy substance that contains poisons according to ‘Drugs’. Those substances may change the tissue (Human body tissue is made up with groups of cells which have similar structure that are working along for the function in human body) in the lungs quickly and when cigarette smoke passes through the lungs, it leaves tar. Although, the body produces mucus to prevent the effects of tar, it can block the way of the air that goes into the body and out and lung.
Over time the damaged cells may become cancerous. Cigars, pipes and cigarettes: the best way to prevent lung cancer is to quit or never start smoking. Environmental Tobacco smoke: more commonly known as second hand smoke. Lung diseases: certain lung diseases such as tuberculosis increase a person’s chance of getting lung cancer Pollution: air pollutants such as the by-products of the combustion of diesel and other fossil fuels. Facts about Lung Cancer: More than one hundred fifty thousand Americans died from carcinoma in 2005.
Genomic instability causes individuals to maintain shorter cell cycles and also causes the bypassing of intracellular and immunological control systems. These factors give cancerous cells an advantage when it comes to growth and multiplying. There have been numerous research projects specifically dedicated to finding why this instability causes this in hopes of finding the underlying issues with cancer and stop it from being one of the leading causes of death. Genomic instability includes variations in small structures. These variations can include increased frequencies in mutations of base pairs, microsatellite instability, and changes in chromosome number or structure which are referred to as chromosome instability.
If the affected cell has severe damage, it will die. Even though it still can reproduce, the daughter cells could be lacking in some life-sustaining component and eventually will die. Another possible result of radiation exposure is mutated cell instead of it dies, and eventually leads to cell mutation which could create malignant tumour. A developing embryo is also sensitive to radiation exposure similar to the tumour but the effects are totally different. It can be said that the whole body sensitivity depends on the most sensitive organs as well as the most sensitive cells.
6 All the chemicals in a single cigarette only so many cause cancer. When you light a cigarette, the heat makes a chemical reaction with the hundreds of chemicals already inside it. As the cigarette turns to ash the 70 of the chemicals enter your body and can produce cancer. The chemicals are toxic enough to kill you. 5 If you don’t want your child to follow in your footsteps, start with not smoking around
Definition of Liver Cirrhosis Cirrhosis is a complication of many liver diseases characterized by abnormal structure and function of the liver. The diseases that lead to cirrhosis do so because they injure and kill liver cells, after which the inflammation and repair that is associated with the dying liver cells causes scar tissue to form. The liver cells that do not die multiply in an attempt to replace the cells that have died. This results in clusters of newly-formed liver cells within the scar tissue. There are many causes of cirrhosis including chemicals (such as alcohol, fat, and certain medications), viruses toxic metals (such as iron and copper that accumulate in the liver as a result of genetic diseases).
However, it cannot cure all the diseases (Gene therapy). One of the things that gene therapy can cure is cancer, at least some of them. In general cancer is a type of cell division that is out of control and can invade other tissues. The cancer cells can then spread throughout the body through the body stream and the lymph system. There are over a 100 different types of cancer.
What are the health effects of pesticides on humans? Pesticides have been linked to cancers, developmental and learning disabilities in children, birth defects, endocrine disruption, neurological conditions and respiratory problems. Pesticides cause cancer by altering DNA synthesis and this results in genetic mutations. Pesticides have been linked to numerous types of cancers. Childrens are the most susceptible to pesticides due to the rapidly dividing DNA in their immature immune system.
However, cancer cells cannot control their division. As a result, these cells form a clump that is commonly referred to as a tumor (neoplasm), especially when the immune system is malfunctioning. Tumors can be benign, harmless and easily taken out or malignant. Malignant tumors block tissues and organs from functioning with each other. Once cancer cells become metastasized, they break away from a host tumor.
It 's not clear what causes ovarian cancer. In general, cancer begins when a genetic mutation turns normal cells into abnormal cancer cells. Cancer cells quickly multiply, forming a mass (tumor). They can in. The type of cell where the cancer begins determines the type of ovarian cancer you have.
Repairing the defective DNA in a cell helps maintain a cells genetic information. In A-T the ATM gene is disrupted in the making of proteins that regulate cell growth. These mutated genes do not repair DNA damage instead they allow for these defects to be spread into other cells. This allows for uncontrolled division and growth of cells which can lead to cancerous tumors. These mutations also allow for unwanted cell death which leads to the loss of important cells in the brain involved with coordination.
When groups of liver cells begin to die off the result is acute hepatitis. It is the gallstones that contain large amounts of viral substances, which will eventually cause cell-degenerative changes. As gallstones increase more cells will become infected and will die, sometimes killing off entire lobules and creating kinks in the blood vessels themselves. This will hinder the bloods ability to circulate freely. Liver cancer will occur only after many years of progressive occlusion of the liver bile ducts.
Skin cancers are cancers that arise from the skin. They are due to the development of abnormal cells that have the ability to invade or spread to other parts of the body. There are three main types: basal-cell cancer, squamous-cell cancer and melanoma. The first two together along with a number of less common skin cancers are known as nonmelanoma skin cancer . Basal-cell cancer grows slowly and can damage the tissue around it but is unlikely to spread to distant areas or result in death.
