Asbestos-Related Lung Cancer

Smokers are more likely to get tonsil cancer, and to die from it, than nonsmokers. Continuing to smoke or drink during treatment can cause treatment complications and may make it not work as well. Jan 28, Cancer is a major health impact of smoking. Many types of cancer such as blood cancer, cancer of the throat, among lung cancer among others have been linked directly to cigarette smoking. Smokers have higher chances of developing any of the types of cancer than non-smokers.

Nicotine is the addictive drug in tobacco smoke that causes people who smoke to continue to smoke. Along with nicotine, people who smoke inhale about 7, other chemicals in smokeds smoke. Many of these chemicals come from burning tobacco leaf.

Some of these compounds smokwrs chemically active and trigger profound and damaging changes in the body. Tobacco smoke contains over 70 known cancer-causing chemicals. Smoking harms nearly every organ in the body, causing many diseases s,okers reducing health in general.

Passive smoking exposure of the rhroat mother to second-hand smoke can also harm the fetus. A person who smokes throughout their life is at high risk of developing a range of potentially lethal diseases, including:.

When asbestos ahat become airborne, people working with asbestos may inhale particles which remain in their lungs. Aspergillus is a fungus that commonly grows on rotting vegetation. It can cause asthma symptoms. Asthma cannot be cured, but with good management people with asthma can lead normal, amokers lives.

Exposure to second-hand smoke increases the risk of children developing asthma and provokes more frequent asthma in children with asthma.

Dangerous chemicals in tobacco smoke Effects of smoking tobacco on the body Effects of smoking on the sexual organs Effects of smoking on babies Diseases caused by long-term smoking Where to get help. Dangerous chemicals in tobacco smoke Highly damaging components of tobacco smoke include: tar is the percentzge for the solid particles suspended in tobacco smoke. The particles contain chemicals, including cancer-causing substances carcinogens.

Tar is sticky and brown, and stains teeth, fingernails and lung tissue carbon monoxide is a poisonous gas. It is odourless and colourless and, in large doses, quickly causes death because it takes the place of oxygen in the blood. In people who smoke, the carbon monoxide in their blood makes it harder for oxygen to get to their organs and muscles oxidizing chemicals what size sup should i get are highly reactive chemicals that can damage the heart muscles and blood vessels of people who smoke.

They react with cholesterol, leading to the build-up of fatty material on artery walls. Their smooers lead to heart disease, stroke and blood vessel disease metals tobacco smoke contains several metals that cause cancer, including arsenic, beryllium, cadmium, chromium, cobalt, lead and nickel radioactive compounds tobacco smoke contains radioactive compounds that are known to be carcinogenic. Effects of smoking on the immune system The effects of tobacco smoke on the immune system include: greater susceptibility to infections such as pneumonia and influenza more severe and longer-lasting illnesses lower levels of protective antioxidants such as vitamin C how to count pregnancy weeks, in the blood.

Effects of smoking on the musculoskeletal system The smokets of tobacco smoke on the musculoskeletal system include: tightening of certain muscles reduced bone density. Effects of smoking on the sexual organs The effects of tobacco smoke on the male body include an increased risk for: lower sperm count higher percentage of deformed sperm genetic damage to sperm impotence, which may be due to the effects of smoking on blood flow and damage to the blood vessels of the penis.

The effects of tobacco smoke on the female body include: reduced fertility, menstrual cycle irregularities, or absence of menstruation menopause reached one or two years earlier increased risk of cancer of the cervix greatly increased risk of stroke and heart attack if the person who smokes is aged over 35 years and taking the oral contraceptive pill. Other effects of smoking on the body Other effects of tobacco smoke on the body include: irritation and inflammation of the stomach percebtage intestines increased risk of painful ulcers along the digestive tract reduced ability to smell and taste premature wrinkling of the skin higher risk of blindness gum disease periodontitis.

Effects of smoking on babies The effects of maternal smoking thrroat an unborn baby include: increased risk of miscarriage, stillbirth how to make a coin bracelet premature pedcentage weaker lungs low birth weight, which may what percentage of smokers get throat cancer a lasting effect of the growth and development of children.

Low birth weight is associated with an increased risk of heart disease, high blood pressure, and diabetes in adulthood increased risk of cleft palate and cleft lip increased risk of attention deficit hyperactivity disorder ADHD. Diseases caused by long-term smoking A person who smokes throughout their life is at high risk of developing a range of potentially lethal diseases, including: cancer of the lung, mouth, nose, larynx, tongue, nasal sinus, oesophagus, throat, pancreas, bone marrow myeloid leukaemiakidney, cervix, ovary, ureter, liver, bladder, bowel and stomach lung diseases such as chronic bronchitis and chronic obstructive pulmonary disease, which includes peecentage bronchiolitis and emphysema heart disease and stroke wat of the digestive system osteoporosis and hip fracture poor blood circulation in feet and hands, which can lead to pain and, in severe cases, smo,ers and amputation type 2 diabetes rheumatoid arthritis.

The main risk factors for mouth and throat cancer are drinking alcohol and smoking or chewing tobacco. But there's growing evidence that an increasing proportion of cancer is caused by HPV infection in the mouth. Around 1 in 4 mouth cancers and 1 in 3 throat cancers are HPV-related, but in younger patients most throat cancers are now HPV-related. UT Southwestern Communications tells stories about the extraordinary work being done here every day and about the dedicated, passionate people behind it. Explore these stories.

Close to 54, Americans will be diagnosed with oral or oropharyngeal cancer this year. It will cause over 9, deaths, killing roughly 1 person per hour, 24 hours per day.

Of those 54, newly diagnosed individuals, only slightly more than half will be alive in 5 years. However this is due to the increase of HPV16 caused cancers which are more vulnerable to existing treatment modalities, conferring a significant survival advantage. So a change in the etiology, not improved early discovery or treatments; which are relatively unchanged from a decade ago, are not the primary cause for improvement.

If you expand the definition of oral and oropharyngeal cancers to include cancer of the larynx, the numbers of diagnosed cases grow to approximately 54, individuals and 13, deaths per year in the U. Worldwide the problem is much greater, with over , new cases being found each year.

Note that the world incidence numbers from the WHO, while the best available, are estimates that users should consider with caveats. Data collection and reporting in some countries is problematic in spite of the professional efforts of the WHO to be accurate.

Statistics on worldwide occurrence. Brain cancer is a cancer category unto itself and is not included in the head and neck cancer group. Historically the death rate associated with this cancer is particularly high not because it is hard to discover or diagnose, but due to the cancer being routinely discovered late in its development.

Today, that statement is still true, as there is no comprehensive program in the US to opportunistically screen for the disease, and without that late-stage discovery is more common. Another obstacle to early discovery and resulting in better outcomes is the advent of a virus, HPV16, contributing more to the incidence rate of oral cancers, particularly in the posterior part of the mouth the oropharynx, the tonsils, the base of the tongue areas which many times does not produce visible lesions or discolorations that have historically been the early warning signs of the disease process in the anterior front of the mouth.

Often oral cancer is only discovered when cancer has metastasized to another location, most likely the lymph nodes of the neck. Prognosis at this stage of discovery is significantly worse than when it is caught in a localized intraoral area.

Besides the metastasis, at these later stages, the primary tumor has had time to invade deep into local structures. Oral cancer is particularly dangerous because in its early stages it may not be noticed by the patient, as it can frequently prosper without producing pain or symptoms they might readily recognize, and because it has a high risk of producing second primary tumors.

This means that patients who survive a first encounter with the disease, have up to 20 times higher risk of developing second cancer. This heightened risk factor can last for 5 to 10 years after the first occurrence. The other far less common oral cancers are ACC and MEC cancers which by comparison are relatively rare, but highly deadly as the depth of knowledge about them is far less than SCC. The demographics of those who develop this cancer have been consistent for some time.

While historically the majority of people are over the age of 40 at the time of discovery, it is now occurring more frequently in those under this age. Exact causes for those affected at a younger age are now becoming clearer in peer-reviewed research, revealing a viral etiology cause , the human papillomavirus version Promoted by some as a safer alternative to smoking, it has in actuality not proven to be significantly safer to those who use it when referring to oral cancers.

Campaigns to promote the safety of smokeless are being initiated, but it is clear that while it may reduce lung cancers, it has a negative effect on the rates of oral cancers, pancreatic cancer, periodontal disease, and the chronic infections that it produces may even link it to heart disease as well. The gains against lung cancers may occur, but there will be new losses in other areas. The jury is out on other new smokeless tobacco dissolvable products, and until their use has acceptable research behind it we recommend avoiding it.

It is also now confirmed that in a younger age group, including those who have never used any tobacco products, have a cause which is HPV16 viral based. The human papillomavirus, particularly version 16, has now been shown to be sexually transmitted between partners and is conclusively implicated in the increasing incidence of young non-smoking oropharyngeal cancer patients.

From a gender perspective, for decades oral has been cancer that affected 6 men for every woman. That ratio has now become 2 men to each woman in anterior of the mouth disease.

Again, while published studies do not exist to draw finite conclusions, we will probably find that this increase is due to lifestyle changes, primarily the increased number of women smokers over the last few decades. As in the above examples, it is unlikely we will find a genetic reason for this. Lifestyle choices still remain the biggest cause. These published statistics do not consider such socio-economic factors as income levels, education, availability of proper health care, and the increased use of both tobacco and alcohol by different ethnic populations, but all these factors likely play a role in who develops the disease.

In oropharyngeal cancers, the disease is dominated by males over women and white males over black males. Understanding the causative factors of cancer will contribute to the prevention of the disease. Age is frequently named as a risk factor for oral cancer, as historically it occurs in those over the age of The age of diagnosed patients may indicate a time component in the biochemical or biophysical processes of aging cells that allows malignant transformation, or perhaps, immune system competence diminishes with age.

Very recent data late lead us to believe that the fastest-growing segment of the oral cancer population is non-smokers under the age of fifty, which would indicate a paradigm shift in the cause of the disease, and in the locations where it most frequently occurs in the oral environment.

The anterior of the mouth, tobacco, and alcohol-associated cancers have declined along with a corresponding decline in smoking, and the posterior of the oral cavity sites associated with the HPV16 viral cause are increasing. However, it is likely that the accumulative damage from other factors, such as tobacco use, alcohol consumption, and persistent viral infections such as HPV, are the real culprits vs something like immune system frailties or age.

It may take several decades of smoking, for instance, to precipitate the development of cancer. Having said that, tobacco use in all its forms is number one on the list of risk factors for true oral cavity cancers in individuals over This percentage is now changing, and exact percentages are yet to be definitively determined and published, as new data related to a decrease in tobacco use are changing the dynamic very rapidly.

When you combine tobacco with heavy use of alcohol, your risk is significantly increased, as the two-act synergistically. Those who both smoke and drink, have a 15 times greater risk of developing oral cancer than others.

It does not appear that the HPV16 viral cause needs to act synergistically with tobacco or alcohol, and HPV16 represents a completely unique and independent disease process in the oropharynx. Tobacco and alcohol are essentially chemical factors, but they can also be considered lifestyle factors since we have some control over them. Besides these, there are physical factors such as exposure to ultraviolet radiation.

This is a causative agent in cancers of the lip, as well as other skin cancers. Cancer of the lip is one oral cancer whose numbers have declined in the last few decades. This is likely due to the increased awareness of the damaging effects of prolonged exposure to sunlight, and the use of sunscreens for protection.

Another physical factor is exposure to x-rays. Radiographs were regularly taken during examinations, and at the dental office are safe, but remember that radiation exposure is accumulative over a lifetime. It has been implicated in several head and neck cancers.

Biological factors include viruses and fungi, which have been found in association with oral cancers. The human papillomavirus, particularly HPV16, has been definitively implicated in oropharyngeal cancers Oropharynx, the base of the tongue, tonsillar pillars, and crypt, as well as the tonsils themselves.

HPV is a common, sexually transmitted virus, which infects about 40 million Americans today. There are about strains of HPV, the majority of which are thought to be harmless. So we wish to be clear. Infection with even a high-risk HPV virus does not mean that you will develop oral cancer.

It is likely that the changes in sexual behaviors of young adults over the last few decades, and which are continuing today, are increasing the spread of HPV, and the oncogenic versions of it. There are other minor risk factors that have been associated with oral cancers but have not yet been definitively shown to participate in their development. These include lichen planus, an inflammatory disease of the oral soft tissues, and genetic predispositions. More about HPV and oral cancer.

More about viruses and all cancers. There are studies which indicate a diet low in fruits and vegetables could be a risk factor, and that conversely, one high in these foods may have a protective value against many types of cancer. More about nutrition and cancer Clearly cancer is a very complex group of diseases, and diet alone should not be considered a stand-alone causative factor for initiation of the cascade of cellular events that change a cell from normal to malignant.

One of the real dangers of this cancer is that in its early stages, it can go unnoticed. It can be painless, and little in the way of physical changes may be obvious. The good news is, that your Physician or Dentist can in many cases, see or feel the precursor tissue changes, or actual cancer while it is still very small, or in its earliest stages.

More about the stages of cancer It may appear as a white or red patch of tissue in the mouth, or a small indurated ulcer that looks like a common canker sore. Because there are so many benign tissue changes that occur normally in your mouth, and some things as simple as a bite on the inside of your cheek may mimic the look of a dangerous tissue change, it is important to have any sore or discolored area of your mouth, which does not heal within 14 days, looked at by a professional.

Unilateral persistent earache can also be a warning sign. Other than the lips which are not a major site for occurrence any longer, common areas for oral cancer to develop in the anterior front of the mouth are on the tongue and the floor of the mouth.

Individuals that use chewing tobacco, are likely to have them develop in the sulcus between the lip or cheek and the soft tissue gingiva covering the lower jaw mandible where the plug of tobacco is held repeatedly.

There are also a small number of cancers that are unique to the salivary glands, as well as the very dangerous melanoma. While the occurrence of these is dwarfed by the other oral cancers, they are a small percentage of the total incidence rate. In the US, cancers of the hard palate are uncommon, though not unknown. The base of the tongue at the back of the mouth, the oropharynx the back of the throat and on the pillars of the tonsils, and the tonsillar crypt and the tonsil itself, are other sites where it is now more commonly found, particularly in young non-smoking individuals.

If your dentist or doctor decides that an area is suspicious, the only way to know for sure if it is something dangerous is to do a biopsy of the area. This is not painful, is inexpensive, and takes little time.

It is important to have a firm diagnosis as early as possible. It is possible that your general dentist or medical doctor may refer you to a specialist to have the biopsy performed. This is no cause for alarm, but a normal part of referring that happens between doctors of different specialties. More about biopsy and diagnosis.

We know that all cancers neoplastic transformations result from changes mutations in genes that control cell behaviors. Mutated genes may result in a cell which grows and proliferates at an uncontrolled rate, is unable to repair DNA damage within itself, or refuses to self destruct or die apoptosis.

It takes more than one mutation to turn a cell cancerous. Specific classes of genes must be mutated several times to result in a neoplastic cell, which then grows in an uncontrolled manner.

When a cell does become mutated to this point, it is capable of passing on the mutations to all of its progeny when it divides. Genetic mistakes randomly happen each day in the course of our bodies replacing billions of cells. Besides these random occurrences, genetic errors can be inherited, be caused by viruses, or develop as a result of exposure to chemicals or radiation. Our bodies normally have mechanisms that destroy these abnormal cells.

We are now discovering some of the reasons this fails to take place, and cancers occur. After a definitive diagnosis has been made and cancer has been staged, treatment may begin.
