I'm trying to keep breast cancer away. I've had it once, and I really don't want it again. So I am committing myself to all strategies for keeping the disease out of my life -- like eating right, maintaining a normal weight, not drinking, not smoking, and as of yesterday, exercising strenuously.

New research shows strenuous exercise is what it takes to minimize the risk of breast cancer. Not moderate. Strenuous.

OK, I'm on board.

Now I've been a student of moderate fitness for most of my life. But now I'm embracing this new approach, this new way of pushing my body to its near limits. I figure if my choice is cancer or strenuous exercise, I better take the route that will leave me sweating and huffing and puffing, not sick and weak and bald. And so yesterday I took my first stab at what I will try to do at least five hours per week -- what experts say it takes to make a difference.

It all started with a warm-up lap on my treadmill -- just one lap at 4.5 miles per hour. Then I upped my speed to 5.3 and ran for a mile and a half. I continued running for another half mile at 6 miles per hour and then began walking again. I started at incline 1 for one minute, then moved to incline 2 for one minute, then incline 3 for one minute, and so on until I reached incline 10. My goal was to then continue walking while decreasing the incline each minute for ten minutes -- but I was so out of breath and fatigued, I jumped the incline down to 4 for one minute, then did 3 for one minute, 2 for one minute, 1 for one minute, and then I stopped. The whole process took about 40 minutes and left me soaked with sweat and gasping for air. Then, just in case my workout wasn't strenuous enough, I did 20 push-ups, a handful of sit-ups, and a few other floor exercises before heading to the shower.

So that's my version of strenuous. Now, I don't plan to do this same exact routine for all five hours I must complete each week, but I do intend to sweat and huff and puff just as much as I did yesterday. Because if strenuous is what it takes to ward off evil cancer cells, then I'm game.

Actress Gwyneth Paltrow has lost five family members to cancer -- and she fears the disease may one day strike her. So she's taking action now and is trying to beat back the cancer curse that seems to loom over her loved ones.

Ever since losing her famous father in 2002 to throat cancer, Paltrow has been approaching life from a biological perspective.

"Cancer has been the curse of my family,"she said. "I am challenging these evil genes by natural means. I am convinced that by eating biological foods it is possible to avoid the growth of tumors. I began this crusade soon after my father's death. Since then the fight against tumors has been my mission."

Paltrow and her husband, Coldplay's Chris Martin, have embraced a strict vegetarian diet for their young family, and they hope their commitment to healthy eating will ward off the illness they fear may be headed right for them.

There is a downside to cancer. There's the distressing diagnosis, the shocking realization that something evil is invading cells and tissues and organs. There's surgery and treatment and loss of hair, loss of blood counts, loss of energy, loss of wellness, loss of future plans and intentions. There's the fear of recurrence and the fear of death and the fear of surviving. Cancer is dark and dismal and daunting. There is no room for argument. There is a downside to cancer.

But there is an upside to cancer too. Really, there is. And a growing body of research suggests cancer changes many people's lives -- like mine -- for the better.

"Cancer gives some survivors a renewed sense of confidence and greater appreciation for their own endurance," says one professor of medicine and public health. "The adversity of treatment may give people the sense that 'I've come through this and I'm stronger.' " Yes!

This same professor says cancer also leads survivors to question their priorities -- and to better manage them. Yes!

She also says survivors tend to find the coping strategies they develop during therapy can help them handle other life problems. Yes!

Many cancer survivors and their families turn to helping others dealing with the disease. It's part of the healing process to give back. And it feels good. Yes!

Cancer almost always is a blessing. This may not be apparent while in the trenches of a cancer fight. But when the smoke clears and the dust settles, blessings emerge. Really, they do.

Today marks the beginning of National Breast Cancer Awareness Month. And today, I realize how aware I am of breast cancer -- how much more aware I am than ever before, compliments of a personal encounter with a disease that snuck up on me with no warning and thrust me into a two-year battle that physically, has just ended. Emotionally, the trek continues. But it's not horrible and it's not disabling -- anymore. On most days, it's enlightening, empowering, strengthening.

I think it's the brush with mortality that woke me up to the privileged life I live. Cancer allows me to wake in the morning feeling alive. It allows me to fall asleep at night feeling thankful. And every day, I am totally, completely, acutely aware of how absolutely lucky I am to be living.

There was a time when October was nothing more than another month to me -- a month that stood out only for the onset of autumn and falling leaves and halloween and trick-or-treat. Now I know October for Breast Cancer Awareness Month -- the month belonging to millions of women living with breast cancer and the millions who need to prepare for a possible breast cancer strike. It's a powerful month, jam-packed with events and activities and promotions and media attention. It's a sad month, marking the loss of life for so many who could not conquer an evil disease. It's a happy month, symbolic of life that goes on despite this same evil disease. It's a month that allows me a lifetime membership. A month that will always be on my radar. A month I can call my own -- a month I am proud to call my own.

Aerosmith bassist Tom Hamilton announced on Thursday -- via his publicist -- that he will miss the beginning of the band's upcoming tour and will rejoin the band in mid-October once he has fully recovered from radiation treatment for throat cancer.

Hamilton, 55, just completed seven weeks of radiation and plans to rest and heal in the company of family. In his absence, David Hull -- a longtime friend and former member of the Joe Perry Project -- will fill in as bassist. The Aerosmith tour -- Route of All Evil -- will begin on September 5 in Columbus, Ohio.
