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 am on the verge of tears watching Danny sleep peacefully and happily in his new big-boy bed, surrounded by comfy covers and his favorite snuggly items. I am choked up by the sight of Joey's two missing front teeth, that smile that shows one big tooth struggling to emerge, the way his tongue slips through that big opening when he says his friend's name -- Catherine -- with the sweetest little lisp.

My boys' milestones have always warmed my heart. Walking behind Joey as he learned to ride his bike with training wheels was a joyous rite of passage. Watching my little boy from behind as he propelled himself forward on our neighborhood sidewalk will be forever etched in my mind. This was before breast cancer, though. Now, after breast cancer, every step my boys take hits me like a ton of bricks.

Breast cancer has turned my heart to mush. I consider it a good thing -- the depth of feeling I experience over every-day matters. I feel more grateful, thankful, and touched by life in general and by my family in particular.

I credit nearly losing everything to my increased sensitivity and softness to the world around me. Life is fragile. I know that now. And for this, I have seven simple words: I promise I will never forget it.

Ovarian cancer is difficult to detect. There are no great screening tests to pick up on its presence in the body, and by the time symptoms appear, the disease has often progressed into an advanced stage. But a ray of light has recently emerged in the study of ovarian cancer -- and it could help in the prevention and early detection of this deadly disease.

Think about this, from the April 2007 issue of Woman's Day magazine:

Researchers at the University of Washington School of Medicine have identified a simple checklist of six symptoms associated with an increased risk of the disease and three of them -- if they occur at least 12 times per month and are present for less than one year -- were present 57 percent of the time in a study of women with early-stage disease.

And the three symptoms are: abdominal and pelvic pain, bloating and difficulty eating, and feeling full quickly.

If you experience these problems, especially if they are frequent or new, contact your doctor because identifying ovarian cancer quickly is key. In its early stages, the cure rate is 90 percent. But for advanced cancer, it's only 20 percent.

I've read stories about women whose breast cancer diagnoses were delayed because they explained away certain symptoms. One woman, an athlete, was told by her husband one day that her nipple looked different from the other. "It's probably just the jog bra I've been wearing all day," she assured him. They both moved on.

Some time later, this woman learned that her different nipple was a sign of breast cancer. And she had it. She just didn't know it. And so her diagnosis came late. Eight years later, this young mother of two small children died from a disease she explained away.

This is normal -- the art of explaining away all the odd messages our bodies give us. Perhaps it's the stigma of whining about every little ache and pain that keeps us from pursuing immediate medical attention. It could be the likelihood that our complaints are pretty normal, so we refrain from rushing to judgment.

I'm practicing this well-established art right now. It's odd for me because I've already had breast cancer, and I am usually ultra-sensitive to every twinge of pain I feel. So when I woke this morning, with a tight and aching feeling in my chest, one would have thought I'd be racing out the door, headed for the nearest emergency room. I considered the fact that perhaps I need to be seen, that a chest X-ray might be in order, but I took no action -- because I explained the feeling away. It went something like this:

It must be the way I slept. I slept in a different bed, with one child and one dog, and I don't think I moved an inch all night.

The feeling gets less intense with time. At this moment, I can only feel something -- and it's very mild -- if I inhale deeply.

If I have the same feeling tomorrow morning, I will pursue it -- no, I won't pursue it just yet because I wont' be sleeping in my own bed for a few more nights. I'll wait until I get back to my own bed and see what happens. Maybe this bed is not good for me.

This goes on and on. For me, I think it happens because I suspect nothing really is wrong with me. Perhaps I am dismissing something serious but mostly, I'm chalking this behavior to progress. Because there was a day when I ran to the dentist for a bump on the roof of my mouth -- it was nothing -- and I cried to get myself a next-day mammogram for some lumpy tissue I was convinced was cancer -- it wasn't -- and now, I am happy to feel more like a normal person. I am happy to have perfected my new art, which incidentally I will abandon in an instant if the discomfort persists.

My husband says he's had this feeling before when getting out of bed. I think I'm going to be OK.

Testicular cancer, cancer in one or both of the testicles, usually occurs in young men and will strike about 8,250 of these men this year. About 370 men will die.

A man's lifetime risk of developing this cancer -- that typically shows up in only one testicle -- is 1 in 300, securing it as one of the less common cancers in the United States. The chances of dying from testicular cancer are 1 in 5,000, making it one of the most curable forms of cancer. Yet it is still the most common form of cancer in men ages 15-34. It is also a cancer commonly characterized by denial and embarrassment. As a result, it is one of the least mentioned cancers.

I just ran three miles on my treadmill. I have never been the athletic one in my family. My sister is the one who was born with the athletic streak -- she played softball and lettered in tennis after giving the sport a try with no previous experience and may have helped her high school basketball team win a state championship if it weren't for the major knee injury she suffered just before the big game. I, on the other hand, was born with a streak that has something to do with hair, nails, and lots of shoes. I was never interested in sports, gym shorts, or sweating -- which is what makes running three miles a big deal for me.

I wish I had started running long ago -- because I really like it. I like the loud music that pumps through my MP3 player and the change in my cadence as each new song begins. I like the motivation of knowing I'm pushing my body and accomplishing a physical challenge. I like that my endurance improves with each mile I travel. I like the mental release and the thoughts that run through my head and the cleansing effect I get from running. And I like sweating.

It's possible running would not have appealed to me long ago, even if I had given it a try -- because times were different long ago. I was healthy. I was happy. And I had no reason to marvel at the possibilities of my body. Without a natural impulse for physical fitness and challenge, I was completely satisfied with the status quo. But now I have an acquired impulse -- because cancer has threatened the very body I once took for granted. And I want it to be strong. I want it to be healthy. I want it to stand up to any possible threat. So I run. And when I am not running, I look forward to running.

In just a few weeks, I will run in the 5K Making Strides for Breast Cancer event with my athletic sister. I will run by her side. With my loud music for motivation. With the inspiration that I am making a difference for my body and for women everywhere. With my gym shorts on. And a ball cap covering my hair. With sweat dripping down my face. I can't imagine a better feeling.

Our days start early now that Joey is in kindergarten and school begins promptly at 7:45 AM. His daddy gets him out of bed at 6:30 AM so he can have some time to wake to the world before shuffling out the door, and we've happily found that Mister Rogers' Neighborhood comes on at just this time. The same Mister Rogers that first appeared on television in Canada in 1963 and then in the United States in 1967 -- with a gentle man, Mister Rogers himself, spreading his calm but uplifting messages to children and nurturing personalities of kids everywhere.

The last original episode of Mister Rogers' Neighborhood was aired in 2001. And in 2003, Fred McFeeley Rogers died at the age of 74 after a brief bout with stomach cancer. But his legacy lives on as his show -- the longest-running PBS program ever -- still graces the television screen. I remember watching this show with my grandmother when I was a little girl. And now I get to watch it with my little boy -- who can also visit Mister Rogers on the PBS website.

Today, Joey and I started our day with a cheery little song, sung by the man who hated television and joined it only to bring about change -- to use this fabulous instrument to guide children in a positive direction. And here is what he sang this morning -- the song that is still playing in my head as I take on the day ahead of me.

It's such a good feeling to know you're alive.
It's such a happy feeling: You're growing inside.
And when you wake up ready to say,
"I think I'll make a snappy new day."
It's such a good feeling, a very good feeling,
The feeling you know that we're friends.

I hope it's a good day in your neighborhood.

Stuffing your emotions, or keeping it all inside, has led more than one person down the path to trouble. At some point, if you do not express your thoughts and feelings, especially the negative ones, you stay emotionally frozen in time. It's kind of like physically clubbing yourself over the head repeatedly day after day. Of course, we cannot go around randomly screaming at people or speaking before we give ourselves time to think. There are effective ways to open up and share that will lead you to better health and help you to maintain a good relationship with family members and friends at the same time. Journaling is good, as is talk therapy or belonging to a support group.

The point is, until expressed, you are stuck with whatever you are feeling. With the passage of time, you might not even be aware of the emotions you are carrying around inside affecting you and your health, as they tend to pile up and become obscured from view.

Adelaide University psycho-neuro-immunology researcher Vikki Knott understands the benefit of letting it all out emotionally, and that sharing and releasing distressful emotions can help a cancer survivor survive cancer longer. Knott will be conducting research in emotion-focused treatments to improve cancer survivorship by charting the physical changes to the immune system before and after talk therapy sessions.

According to Knott, "It's about the link between the mind and the body and how your mind state can affect the disease state in the body." The researchers will be examining three techniques -- journaling, meditation and hypnosis. Previous research has already proven that breast cancer survivors who belong to a support group tend to live longer than their more isolated and disconnected counterparts.
