Causes of head and neck cancers




Head and neck can­cers are said to be on the increase global­ly, hence experts are working hard to find lasting solution to the disease.
According to medical ex­perts, the moist surfaces inside the mouth, nose, and throat are the most common places for head and neck cancers to grow.



The salivary glands also have cells that can become cancerous, but that’s more rare. Medical experts have therefore, further classified these tumors by their specific location in your body.
Symptoms
According to medical ex­perts, a lump in ones neck or a sore in the mouth that doesn’t heal is a cause for concern.
Other warning signs, ac­cording to the experts, in­clude hoarseness or a scratchy throat that doesn’t get
better and pain in the neck, jaw, or ears.
One might also have nosebleeds often or be con­gested. Many of these issues can be caused by other con­ditions, too.
What raises ones chanc­es?
The medical experts fur­ther noted that if one regu­larly drinks alcohol and use tobacco -- smoke or smoke­less -- he or she is more likely to get a head or neck cancer than someone who doesn’t. People with the hu­man papilloma virus (HPV) have higher odds, too, and poor dental health also can boost your chances.
Oral Cancer
These cancers, experts say, affect the lips and gums, the front two-thirds of the tongue, the cheek and lip lin­ings, under ones tongue, and the roof of the mouth.
According to the experts, because of this, the dentist might be the first to spot a problem. Early signs include a lump or sore that doesn’t heal, and one might see a red or white patch on his gums or inside his cheek. If ones dentures start to fit poorly, that’s another symptom.
Treatment for oral cancer
Standard treatment for oral cancers, experts say, in­volves surgery to take out the cancer and any abnormal tis­sue that may have spread to other areas, including lymph nodes in the neck or near­by bone.
The experts further say, this is usually followed by radiation therapy, which kills any remaining cancer cells or stops their growth. The medical team might in­clude an ENT (ear, nose, and throat) doctor, cancer spe­cialists, dentist, plastic sur­geon, and speech therapist.
Nasal cavity cancer
In this form of cancer, ac­cording to experts, the can­cer cells can grow in the tis­sue behind the nose (the nasal cavity) and the hollow areas in the bones near it, called the paranasal sinuses.
Symptoms include con­stant congestion, sinus in­fections that don’t get better with treatment, headaches, swollen eyes, and problems with your sense of smell.
Salivary gland cancer
Found in the floor of the mouth and near the jaw­bone, these make saliva. Symptoms of this type of cancer include pain, numb­ness, or weakness in your face. You also may have trou­ble swallowing or opening your mouth wide. Fluid that drains from your ear is an­other sign. This condition is linked to exposure to radia­tion -- as a treatment for an earlier cancer, for example.
Salivary gland cancer di­agnosis

The doctor will use a nee­dle or tiny cut to take out a small part of the problem area and look at it under a microscope to make sure it’s cancer. If possible, he might take out the entire tumor.
