As evidence mounts, it's becoming more and more clear that chemo brain, a mental fogginess that can result from chemotherapy, is a real concern and not just a convenient excuse cancer patients use to explain away their flighty and forgetful tendencies. It seems the brain really can suffer cognitive damage from the poisonous drugs that fight off deadly cancer cells. And sometimes, this damage is present years after treatment.

Add to chemo brain the normal aging process as well as brain conditions such as mild cognitive impairment and even schizophrenia and the brain might not stand a chance of ever remembering anything. Unless we buy into the new concept of mental training -- somewhat like physical fitness training -- in which case we may be able to bring back a level of sharpness to our lives.

Research suggests this type of training may delay mental decline. And Betty Hall, 85, who is taking a brain fitness class at her senior living complex in Illinois, says brain-enhancing activities are definitely helping her.

Hall is participating in an eight-week program where she spends one hour per day, five days per week using a computer to match words and listen for details in stories. She says it's helping her remember where she places her keys and her grocery lists -- and it's even helping her in her bridge club.

"I've won four times out of the last five at bridge club, and I think the players are going to shoot me because I keep remembering the cards people have," she said. "It's much easier for me to concentrate . . . and I brag about it everywhere I go."

One clinical professor of neurology says brain health programs will explode over the next few years because of the stunning findings on this front. One study shows relatively short training regimens, lasting just five or six weeks, improve functioning for as long as five years. And booster sessions help advance these gains. Study participants says their everyday tasks, like managing finances, are much easier after mental workouts. Another study of the computer software Hall uses shows the program shaves an average 10 years off the mental age of users.

Not all mental training is alike, and different cognitive difficulties may call for different training protocols. But the simple fact that I can work out my brain like I can work out my body gives me hope that I can possibly reverse the effects of chemotherapy on my own foggy brain, that I can one day not worry anymore that I might find my check book in the refrigerator and my cell phone in my sock drawer. Bring on the workouts!

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.

For the almost two years I have been receiving treatment for breast cancer, I have traveled the same path -- over and over and over again -- from my house to the hospital and back again. And while I have seen different doctors and received different treatments and visited various departments and locations for all sorts of surgeries and tests and scans and X-rays, the path has remained the same. And after all the time that has passed, the power of the path has never diminished -- despite how familiar it has become.

Today I drove from my house to the hospital for a counseling appointment. I drove the same stretch of highway for a few miles, got off on my usual exit, drove for a few more miles past all the typical shopping centers and restaurants, and came to the light where I always turn left into the Cancer Center. I drove into the parking lot, found a parking space -- thankfully -- and displayed my yellow patient parking permit that allows to park without fear of a $20 ticket. I got out of my car and began my walk to the main hospital where the psychology clinic is located. I passed -- as usual -- the startling crowds of people smoking outside the Cancer Center, the groups of medical students who gather outside the medical facilities, the masses of people in white coats racing around and checking beepers and talking on cell phones. I entered the hospital, traveled to the ground floor, and turned a few corners until I reached my clinic. I checked in, paid my $25 co-pay, and waited for a just a few minutes until I was greeted by my counselor. We walked to a private room, talked for an hour, and then I followed my path in reverse.

The path is always the same. It is routine and predictable and rarely varies. But it has never become dull and I have never become numb to it -- because the power that is wrapped up in my drive and my subsequent steps that take me to and from my destinations still has a tight hold on me. I can travel the same path for other purposes -- to shop or have dinner -- and the power is lost. But when I travel for reasons all about cancer, the power overwhelms me. It happened today -- as I drove listening to the same CD I always play on these missions, as tears filled my eyes. I was not sad -- just overflowing with emotion. Emotion about all that I've encountered -- the encounters with fear and dread and total repulsion and the encounters with hope and joy and pure contentment. Today I felt powerful. Simply powerful. Because I have overcome what has faced me so far and because I am still traveling the same road, the same path to ensure my future health and well-being -- which is something I hope to become all too familiar with.

This is amazing. Oklahoma Medical Research Foundation researchers have found a way to do what was thought to be impossible -- reverse the process of cell division. "Until now no one has been able to make the cell cycle go backwards," states Gary J. Gorbsky, Ph.D., a scientist with the Oklahoma Medical Research Foundation. According to the researchers, they were able to successfully control a protein responsible for the division process, interrupt and reverse the event, and send duplicate chromosomes back to the center of the original cell. To me, this ranks right up there with someone announcing they have perfected time travel. The implication of possibility in being able to reverse the cellular process is mind-boggling. It's science -- and not fiction.
