Mouth C ancer

6comments
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.

Liver Cancer

1 comment
Liver cancer refers to the growth of malignant tumors in liver tissue. Cancer that starts in the liver is called primary liver cancer. Cancer that spreads to the liver from another organ is called metastatic liver cancer.

The symptoms of liver cancer:

Often there are no symptoms of liver cancer until the later stages. This is why early detection is difficult. When symptoms do occur, they may include fatigue, pain on the right side of the upper abdomen or around the right shoulder blade, nausea, loss of appetite, feeling full after a small meal, unexplained weight loss and jaundice (yellowing of the eyes and the skin). If you have one or more risk factors for liver cancer and any of these symptoms, you should see your doctor immediately.

Causes OF liver cancer:

There are several risk factors that increase the likelihood someone will get liver cancer.

* Cirrhosis, or scarring, can lead to liver cancer. Over 80 percent of liver cancer cases are linked to cirrhosis. In the United States, hepatitis C and alcohol abuse are the leading causes of cirrhosis.
* Long-term infection with hepatitis B and C are linked to liver cancer because they often lead to cirrhosis. Hepatitis B can lead to liver cancer without cirrhosis.
* Smoking is another probable risk factor, especially among people who abuse alcohol and have cirrhosis.
* Obesity also appears to be linked to primary liver cancer. Less common risk factors include abuse of anabolic steroids, or male hormones, for strength conditioning; exposure to arsenic in drinking water; and exposure to certain chemicals in the plastics industr

Abnormal development of cells leads to the growth of tumor, when tumor is malignant in nature they are termed as cancer. Breast cancer is the most common type of cancer diagnosed in women today. Around the world breast cancer statistics shows that after lung cancer breast cancer is the second most death-causing factor in people who develops cancer.
The risk factor of developing breast cancer increases with the age, it does not only relate to women, figures show that out of every 100 women there is one male who is diagnosed of breast cancer.

Breast cancer does not mean a specific category of disease rather it is the different types of cancer generally found in breast is collectively termed as breast cancer. Though the most common understanding suggests that, abnormal growth of cells in the breast causes breast cancer.

Cancer is the general name for a group ofmore than 100 diseases in which cells in a part of the body begin to grow out of control. Although there are many kinds of cancer, they all start because abnormal cells grow out of control. Untreated cancers can cause serious illness and even death.
