Dry mouth (xerostomia), is most commonly caused by radiation therapy directed at the head and neck region of the body. Radiation may irreversibly affect the production and quality of saliva in the salivary glands. A number of medications can also induce xerostomia. Dry mouth may affect the patients speech, taste sensation and ability to swallow.

Many patients complain of a sore or burning sensation, cracked lips, and fissures in the corners of the mouth. There is also an increased risk of cavities and mouth disease due to less saliva to cleanse the teeth and gums.

There are now some means of preventing xerostomia that were not available a few years ago. Amifostine, a radiation protector of normal tissues, has been shown to protect the salivary glands when given daily with radiation therapy. Also, a treatment known as Proton therapy may allow the radiation oncologist to spare the salivary glands from getting significant radiation doses. This may prevent dry mouth in the future. If you are getting radiation therapy to the head and neck region, you should discuss these options with your radiation oncologist. If you have developed xerostomia, there are management strategies that can effectively deal with your dry mouth and prevent cavities and periodontal disease.

Try to follow these simple guidelines:

• Perform oral hygiene at least four times a day. (After each meal and before bedtime)
• The oral cavity should be rinsed and wiped immediately after meals
• Dentures need to be brushed and rinsed after meals
• Only use toothpaste with fluoride when brushing
• Keep water handy to keep the mouth moist at all times
• Apply prescription strength fluoride gel at bedtime
• Rinse with salt and baking soda solution 4-6 times a day
• Avoid liquids and foods with high sugar content
• Avoid rinses containing alcohol
• Use moisturizer regularly on lips
• Oral pilocarpine (Salagen) is the only drug approved by the FDA to stimulate saliva secretion from the remaining salivary glands.

Luanne Austin says chemotherapy is not all it's cracked up to be. She doesn't mean it's cracked up to be something really great but is far from such a thing. She means it's cracked up to be something pretty horrible but is really not all that bad.

Austin says the day her doctor announced she would receive chemotherapy was almost as bad as the day she learned she had breast cancer. That's because she had heard nothing but bad things about the treatment. She expected to be laying in bed with her life in the balance -- nauseated, vomiting, sick -- as the "cure" killed her.

All expectations aside, Austin decided to tackle chemotherapy with a positive attitude. This may seem a daunting task -- turning a dreaded chemotherapy protocol into a not-so-bad experience -- but Austin mastered the task. And here are seven of her positive thoughts about a treatment that is not all it's cracked up to be.

• Austin talked to people who had traveled journeys similar to hers. What she learned is that many women continued working through treatment. Some suffered very few side effects. One woman even told Austin her experience was super. Austin was inspired by the positive women she tracked down. And now she inspires others.
  

• Austin did some reading. She learned that chemotherapy drugs target quickly-dividing cells, like cancer cells, red and white blood cells, blood platelets, and digestive tract cells. Learning about the process helped her realize chemotherapy was intended to make her well, not make her suffer.

• Austin learned how to support her body through treatment. She came to understand that the best chance of surviving breast cancer comes from conventional medicine -- surgery, chemotherapy, radiation -- but that alternative treatments can complement the traditional approach. She recommends the book Breast Cancer: Beyond Convention and considers her pursuit of a healthy diet, exercise, supplements, and a good night's sleep some of her most helpful chemotherapy add-ons.

• When Austin felt weak, tired, and just plain zoned out, she retreated to her bed with a good book and a cup of tea. Instead of considering it a setback, she called this downtime a good excuse to spend hours reading.

• Austin found relief from her nurses. They were terrific, she recalls, and professional and friendly and respectful too. Getting to know her medical crew -- and receiving hugs from them at the end of her treatment -- confirmed chemotherapy has some good points.

• For Austin, God -- who carried her through her whole journey -- was instrumental in her positive outlook. She felt lifted up and carried, she says.

• And then there's love -- pure and simple love from her husband and family members -- that allows her to conclude that chemotherapy is not so bad. "I'd have to say chemotherapy hasn't been all that bad," she says. "Not bad at all."
