Mouth C ancer

Tobacco use is by far the most common risk factor for cancers of the mouth and throat. Both smoking and “smokeless” tobacco (snuff and chewing tobacco) increase the risk of developing cancer in the mouth or throat.

All forms of smoking are linked to these cancers, including cigarettes, cigars, and pipes. Tobacco smoke can cause cancer anywhere in the mouth and throat as well as in the lungs, the bladder, and many other organs in the body. Pipe smoking is particularly linked with lesions of the lips, where the pipe comes in contact with the tissue.

Smokeless tobacco is linked with cancers of the cheeks, gums, and inner surface of the lips. Cancers caused by smokeless tobacco use often begin as leukoplakia or erythroplakia.Other risk factors for mouth and throat cancer include the following:

Alcohol use: At least three quarters of people who have a mouth and throat cancer consume alcohol frequently. People who drink alcohol frequently are 6 times more likely to develop one of these cancers. People who both drink alcohol and smoke often have a much higher risk than people who use only tobacco alone.

Ultraviolet light exposure: People who spend a lot of time in sunlight, such as those who work outdoors, are more likely to have cancer of the lip.

Chewing betel nut, a prevalent practice in India and other parts of South Asia, has been found to result in mucosa carcinoma of the cheeks. Mucosa carcinoma accounts for less than 10% of oral cavity cancers in the United States but is the most common oral cavity cancer in India.

Human papillomavirus (HPV) infection: Several strains of HPV are associated with cancers of the cervix, vagina, vulva, and penis. The link between HPV and oral cancers is not known, but HPV infection is believed to increase the risk of oral cancers in some people.These are risk factors that can be avoided in some cases. For example, you can choose to not smoke, thus lowering your risk of mouth and throat canc
The incidence of mouth and throat cancers increases with advancing age.

Sex: Mouth and throat cancer is twice as common in men as in women. This may be related to the fact that more men than women use tobacco and alcohol.The relationship between these risk factors and an individual’s risk is not well understood. Many people who have no risk factors develop mouth and throat cancer. Conversely, many people with several risk factors do not. In large groups of people, these factors are linked with higher incidence of oropharyngeal cancers.

Symptoms of Mouth Cancer

People with an oropharyngeal cancer may notice any of the following symptoms:

A painless lump on the lip, in the mouth, or in the throat

A sore on the lip or inside the mouth that does not heal

A painless white or red patch on the gums, tongue, or lining of the mouth

Unexplained pain, bleeding, or numbness inside the mouth

A sore throat that does not go away

Pain or difficulty with chewing or swallowing

Swelling of the jaw

Hoarseness or other change in the voice

Pain in the ear These symptoms are not necessarily signs of cancer. They may be caused by many other less serious conditions.

If you have any of the symptoms of head and neck cancer, make an appointment to see your primary care provider or your dentist right away.

Quitting smoking is not an easy task, and smoking tobacco is not something that can just be shrugged off at a whim once started. The best course of action is to never smoke cigarettes in the first place, but for many of us it's too late for that. The best way to overcome any challenge, I find, is to learn as much as possible first.

I've been visiting your blog lately. Your blog certainly provides some interesting health information.

I wanted to share some information with you on apples.Apples, for ages, have known to be a healthy for our body.But a new research by German researchers Dr. Dieter Schrenk, M.D. and his colleagues has demonstrated that components in both apple pectin and apple juice actually enhance biological mechanisms that have anticarcinogenic effects in the colon.

Our company represents Washington Apple Commission in India. We do not sell or import these apples. Our mandate is only to make consumers aware of the nutrition benefits of apples.
We'd like to send you the information along with some Washington apples for you to enjoy.We would appreciate your feedback on the same.

With the busy life of so several people today, sometimes it is complicated to find an effectual method to lose weight. When you feel like you are for all time pressed for time, you tend to eat less strong and pay less concentration to your fitness overall.
