By far, smoking tobacco causes most lung cancers. Tobacco smoke has many carcinogens - substances that damage cells. The risk of lung cancer begins to slowly decrease as soon as a person quits smoking. Although smoking is without question the major cause of lung cancer, there are some other causes as well. Passive smoking is one. Exposure to other carcinogens, such as asbestos, is another. Tuberculosis (TB) can increase the risk.

In a nutshell, smoking, smoking, and smoking. The CDC reports that smoking tobacco is the major risk factor for lung cancer. In the U.S., about 90% of lung cancer deaths in men and almost 80% of lung cancer deaths in women are due to smoking. Smokers are 10 to 20 times more likely to get lung cancer or die from lung cancer than people who do not smoke. Secondhand smoke is also linked to lung cancer.

Colorectal cancer occurs in men and women of all racial and ethnic groups. Approximately 75% of colorectal cancers occur in people with no known risk factors. Other important facts about risk for colorectal cancer include: More than 90% of colorectal cancers are diagnosed in people aged 50 or older. The risk of developing colorectal cancer increases with age. A family history of colorectal cancer or colorectal polyps may increase a person's risk of developing colorectal cancer.

A large proportion of cancers is life-style related. The chances of developing cancer depends upon choice of foods, smoking habits, drinking habits, personal hygiene standards and exposure to certain agents at workplace environment. (One should visit for medical counseling to a cancer specialist and identify whether one belongs to high risk group of people likely to suffer from cancer and get adequate investigations

The exact cause of this disease is unknown. However, research does show that some men are more likely than others to develop testicular cancer. Possible risk factors include the following: Miners, gas workers, leather workers, food and beverage processing workers, utility workers, and others are at increased risk. men whose mother took a hormone called DES (diethylstilbestrol) during pregnancy to prevent miscarriage

Summary of Recommendations for Screening and Surveillance Colonoscopy in Individuals at Increased Risk for Colorectal Cancer

Cancer is rarely triggered by a single factor. It usually results from an interplay between environmental factors - such as carcinogens or viruses - on one hand, and factors within the body - such as hormones and inherited genes - on the other. Among numerous carcinogens, tobacco towers over the rest as the biggest killer. In the US, for example, it is responsible for 30% of all cancer deaths and 87% of lung cancer deaths.

African American, American Indian, Asian American, Pacific Islander, or Hispanic American/Latino heritage Abnormal cholesterol with HDL ("good") cholesterol is 35 or lower, or triglyceride level is 250 or higher

The measurements of total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides are commonly performed to determine such risk. Very few methods measure LDL cholesterol directly. Instead, it is calculated.

Women need to examine their breasts once a month, as well as get regular breast examinations, mammograms, and Pap smears Ask your doctor for other specific recommendations, particularly if you have a family history of cancer

Follow the testing guidelines set by the American Cancer Society. Testing can find precancerous polyps. Removing these polyps can prevent most colon cancers. Testing also can help detect colon cancer early, when the chances for successful treatment are greatest. Know your family history. If colon cancer runs in your family, you may need to be tested earlier and more often.

It is difficult to discover what causes cancer from one person to another, but researchers have found several factors that increase a woman’s likelihood of developing vulvar cancer. Some risk factors for vulvar cancer include: Age – Of women who develop vulvar cancer, three-fourths are over 50 and two-thirds are over 70.The average age at diagnosis is 65 years; however, vulvar carcinoma is becoming more common in women under 40.

Yes, as many as 90 percent of head and neck cancers arise after prolonged exposure to specific factors. Use of tobacco (cigarettes, cigars, chewing tobacco or snuff) and alcoholic beverages are closely linked with cancers of the mouth, throat, voice box, and tongue. (In adults who neither smoke nor drink, cancers of the mouth and throat are nearly nonexistent.) Prolonged exposure to sunlight is linked with cancer of the lip and is also an established major cause of skin cancer.

Although the exact steps that lead to bladder cancer are not clear, there are some known risk factors. Here are the most important risk factors for bladder cancer: Chemicals: Working in the dye, rubber, leather, textile, paint or print industries, or working with organic chemicals or chemicals called aromatic amines, increases a person’s chances of developing cancer if appropriate safety measures are not followed.

It is difficult to discover what actually causes cancer from one person to another, but researchers have discovered several factors that increase a woman’s likelihood of developing ovarian cancer.

There are several potential risk factors that may increase the likelihood of developing breast cancer. Here are some of these risk factors:

Women are at increased risk of developing a UTI for several reasons: 1) Anatomy - close proximity between the urethra and the rectal and vaginal area allows bacteria easier access into the bladder. 2) Sexual Activity – sexually active females are at higher risk for developing UTIs due to the close proximity of the vagina to the urethra. It is important to know that bacteria causing bladder infections are not passed between partners.

Plantar fasciitis / heel pain syndrome usually presents during adulthood and doesn’t normally affect children. Juvenile onset of heel pain syndrome is usually caused by trauma to the heel and is usually self-limiting. In other words, with a little rest the heel pain resolves on its own. Damage to sensitive growth plates in the bones of children can cause complications. Therefore, heel pain lasting beyond a few days up to a week should be evaluated by a qualified health care practitioner.

In most cases, doctors cannot explain why a woman develops breast cancer. Studies show that most women who develop breast cancer have none of the risk factors listed below, other than the risk that comes with growing older. Also, most women with known risk factors do not get breast cancer. Scientists are conducting research into the causes of breast cancer to learn more about risk factors and ways of preventing this disease. Risk factors are: Age. The risk of breast cancer increases with age.

Some people are more likely to develop colorectal cancer than others. Studies have found that certain factors increase a person’s risk. The following are risk factors for this disease: Polyps – Most (perhaps all) colorectal cancers develop in polyps. Polyps are benign, but they may become cancerous over time. Removing polyps is an important way to prevent colorectal cancer.

In most cases the cause of breast cancer is unknown. However, the following risk factors have been identified: Family history eg if a woman’s sister, mother or daughter has developed breast cancer her risk of developing it is also increased. Ongoing studies are looking at the effect of a diet low in fat, high in fruit and vegetable intake on reducing the risk of developing breast cancer.

Risk factors for developing kidney cancer include: overuse of painkillers, smoking, obesity, high blood pressure, long-term dialysis, occupation, gender and Von-Hippel-Lindau (VHL) syndrome. Phenacetin, once commonly used in over-the-counter painkillers, has been linked to RCC, typically in patients that have used them in excess. It has also been shown that smokers are twice as likely to develop kidney cancer as non-smokers.

Colorectal cancer affects an equal number of men and women. Colorectal Cancer is the second leading cause of cancer deaths in the United States. The number of new cases and the number of deaths to colorectal cancer has been decreasing as preventative screening and colon health awareness has increased.

Parents, children or siblings of a person who has had colorectal cancer are somewhat more likely to develop this cancer themselves. This is especially true if the relative has the cancer at a young age. If more than one family member has had colorectal cancer, the chances increase even more.

Most people have about a six percent chance of developing colon cancer at some point in their lives. Some things, like a personal or family history of cancer, may increase your risk. Other things, like following colon cancer screening guidelines, decrease your risk.

Menstrual history�if you began menstruating before age 12, or completed menopause after age 55 Family history�if you have a mother, sister or daughter who has had the disease, or a close relative, such as a cousin or an aunt with a history of breast cancer Oral contraceptives�slight increased risk if you are currently using the pill, or have used it in the last 10 years High breast tissue density�a mammographic m.

To predict when and in whom breast cancer will occur, scientists must often think like detectives, looking for clues to signal which women may be more likely than others to develop the disease. These clues are called "risk factors." To identify risk factors, scientists continually examine various trends and patterns among women worldwide who are diagnosed with the disease.

The risk increases with age, with persons over the age of 60 being at greatest risk for developing esophageal cancer. Using any form of tobacco raises the risk of esophageal cancer. The longer tobacco is used, the greater the risk, with the greatest risk among persons who have indulged in long-term drinking with tobacco use. Scientists believe that these substances increase each other's harmful effects, making persons who do both especially susceptible to developing the disease.
