Our bodies are good at telling us when something is wrong most of the time. It is important to listen to those messages and seek medical attention when specific symptoms arise. The June issue of the Mayo Health Letter covers symptoms that should not be ignored.

Seven symptoms not to ignore:

• Unexplained weight loss: This could be a symptom of such conditions as an overactive thyroid, depression, liver disease, cancer or other noncancerous disorders that interfere with how well your body absorbs nutrients.
• Fever: A fever can point to underlying infections. A fever accompanied by chills or one that is greater than 103 degrees should be evaluated immediately.
• Shortness of breath: Gasping for air or wheezing are medical emergencies. Shortness of breath can be caused by asthma, heart problems, anxiety, panic attacks, or a blood clot in the lungs.
• Severe headaches: A headache accompanied by a fever, stiff neck, rash, mental confusion, seizure, vision changes, weakness, numbness, speaking difficulties, scalp tenderness or pain when chewing are medical emergencies. Causes vary for headaches and may include stroke, blood vessel inflammation, meningitis, brain tumor, aneurysm or bleeding on the brain. Most headaches, are just that, headaches but it is important to know the warning signs for more serious underlying conditions.

I wish I could reverse the damage I've already done to my skin after too much time spent in the scorching sun, in search of a tan. It's seems unfair that a tan is so temporary -- yet its damage is everlasting. And it seems crazy that so many people are still searching for a tan -- when it has become so clear that is it so harmful.

As many as 60,000 people a year die from too much sun -- mostly from malignant skin cancer -- according to the World Health Organization (WHO). About 48,000 deaths are caused by malignant melanomas, and 12,000 deaths are caused by other kinds of skin cancer. And 90 percent of these cancers are caused by ultraviolet light from the sun. Cancer is not the only side effect of sun exposure, though -- serious sunburn, wrinkling, eye cataracts, growths on the flesh of the eye, cold sores, and other illness can result from the sun.

We all need some sun -- the vitamin D that is produced in the body by the sun helps to prevent disease and immune disorders. But too much is dangerous and sometimes deadly. Yet almost all ill effects from the sun can be prevented. And the WHO has released a report that advises people to seek shade, to use sunscreen with an SPF of at least 15, and to stay out of tanning salons. The report operates under the premise that sunscreens be used not to prolong sun exposure but to protect the skin when exposure is unavoidable.

The bikini turns 60 this month and makes news not just for its birthday but also for its new feature -- a built-in alarm to warn wearers to get out of the sun. Not all bikinis will talk -- but those made by Canadian company Solestrom will. Solestrom has created a new bikini that goes on sale next month with a UV meter built into its belt and an alarm that sounds when it's time to seek shade. The meter on the $190 bikini displays a level of UV intensity on a scale from 0 to 20. Three to five is moderate strength, eight to 10 is very high, and anything above 11 is extreme. A person's sensitivity to UV depends mainly on skin type so this scale operates in general terms.

Despite increasing awareness of the sun's dangers, sales remain strong for the bikini. So Solestrom developed this suit to ease some of the worries about the sun's damaging rays. They have already been met with high demand from Australia and South Africa -- where skin cancer rates are highest. The United States -- now in the loop too -- has about 1 million new skin cancer cases each year.

Young women sometimes are dismissed when they pursue medical attention for suspicious lumps, bumps, pains, or changes in their breasts -- because breast cancer is not so common in young women and medical professionals may assume that breast cancer is not the culprit for the complaints brought before them by young women. But young women do get breast cancer -- I did at age 34 -- and many times, the tumors found in young breasts are more aggressive than those that appear for older women. So it is critical that young women seek medical attention for anything out-of-the-ordinary. And it is critical that doctors respond with urgency so that breast cancer in young women can be detected early -- and treated appropriately.
