Liz Claiborne, fashion designer for working women climbing corporate ladders, died Tuesday at the New York Presbyterian Hospital after battling cancer for many years. She was 78.

Said Bill McComb, CEO of Claiborne's company since November: "In losing Liz Claiborne, we have not only lost the founder of our company, but an inspirational woman who revolutionized the fashion industry 30 years ago. Her commitment to style and design is ever present in our thinking and the way we work. We will remember Liz for her vision, her entrepreneurial spirit and her enduring compassion and generosity."

Claiborne, with husband Art Ostenberg and partners Leonard Boxer and Jerome Chazen, launched her label in 1976 after working for years as an unknown dress designer. Her brand featured ensemble sportswear with price tags below that of other designers and revolutionized the department store industry. Once compartmentalized, with pants in one department and skirts in another, Claiborne's coordinated clothing inspired the merging of once-separate departments.

Not all melanomas are alike, and the characteristics of a fast-growing melanoma skin cancer begin in skin tumors that are thicker, symmetrical, elevated, have regular borders or have symptoms, according to the conclusions of a survey study completed by Peter MacCallum Cancer Center researchers. They also note that the faster-growing melanoma is more likely to affect men 70 years or older and individuals with fewer moles and freckles.

"In summary, this study provides descriptive data on the spectrum of melanoma rates of growth and insights into subgroups of patients with melanoma that are associated with rapid growth," stated the researchers. "We propose that this information on melanoma rate of growth be incorporated into education programs for patients and health professionals."

The advantage of identifying the more aggressive melanoma will allow for more aggressive treatment. Details of the study will be published in the December issue of Archives of Dermatology. Of the different skin cancers, melanoma is the most serious and most often appears as a change in size, shape, or color of a mole.

In the not-too-distant future, dermatologists will be able to diagnose skin cancer without ever cutting the skin.

Right now, doctors cut out all suspicious lesions in order to examine them, to determine if they are cancerous or not. But with the development of a new microscope, cells can be examined right on the body -- without cutting.

Moles matter, reported Matt Lauer on Thursday's TODAY show during an interview with a skin cancer expert. Moles are highly associated with melanoma, the deadliest form of skin cancer. So it is critical that each mole is investigated. With this new high resolution technology -- essentially a video biopsy -- a camera will allow doctors to view cells, zero in on the area of concern, and pinpoint the exact cells that make up a mole. If the cells are similar in shape and size and have equal distribution, the mole is normal. If the individual cells are irregular and have no uniform pattern, the mole is abnormal and probably cancerous.

While cutting for biopsy purposes will one day be a thing of the past, cutting will still be necessary if a mole is characterized by cancerous cells. If it's cancer, it must come out. But the video biopsy can be used to map the border and boundaries and will allow for precise removal of the mole.

This technology is still developing -- but one day, perhaps eight to 10 years from now -- doctors will be able to more consistently detect cancer without removal of skin. For now, they must take a piece of the mole and put it under a microscope.

There are definite warning signs of skin cancer. Any mole that is asymmetrical with irregular borders and varied, dark colors should be reported to a physician. Also, any mole that changes in color, shape, or size and is bigger than a pencil eraser is cause for concern.

If I could go back in time, I would not repeat my journey with breast cancer. I would choose a different path -- one free of disease and treatment and the fear that comes with it all. I would choose the route where my children would never hear me say, "mommy has cancer." The route where there would be less worry about dying, less worry about how my kids would do without me, less worry about how all my loose ends would be tied up without me here to tie them. I would choose another direction in a heartbeat. But there are some things I do treasure about my trip down breast cancer lane -- some things I do not wish to give back, even if given the chance to choose a different path. They are the hidden treasures I discovered along the way, in the midst of a harrowing, sometimes horrendous battle. There are many treasures that have come my way -- and I'm sure there are more to come. Here are seven of my valuable finds.

I have tried to exercise most of my adult life -- at times because I felt obligated to participate in what I knew was good for me and at times to justify eating my favorite foods while maintaining an appropriate weight and at times because I wanted to actually have a toned, healthy body.

At this exact time in my life, I exercise with all of these motivations in mind -- plus a few more. I like to sweat and know I am accomplishing a physical feat. I like the mental release I get when I push my body to perform. I like the time to myself, the loud music I hear on my MP3 player, and the results I see from a little bit of hard work. And lately -- as a result of a new weight training program -- I know I am benefiting my body more than ever before.

The following are just seven of the many gifts that come from weight training. Gifts that will make me a happier, healthier cancer survivor.

Noticeable physical results -- Mostly, walking and occasional jogging have been my methods of exercise. And I've seen results from this type of workout -- leaner legs, more defined calf muscles, and the knowledge that I am increasing my cardiovascular health, as confirmed by the technician who performed an ultrasound on my heart in preparation for my Herceptin treatment for breast cancer. He told me he could tell I exercised regularly because of my low resting heart rate. But until I started weight training a few months ago, I never witnessed quick results. Yet after a few weeks of resistance exercise -- lifting 20-pound weights for my arms, shoulders, back, and chest -- I could see definition and tone that clearly would not have resulted from my purely cardio workouts.

Improved strength and endurance -- Lunges and squats and jumping with resistance bands have strengthened my legs. Lifting weights has strengthened my arms -- and I can now lift heavier weights than when I first started my new routine. I can do more push-ups now too -- not girl push-ups on my knees but real push-ups -- than I ever could have imagined doing when I could barely lower my own body weight and would crash to the floor on my stomach. My strength has improved. My endurance has improved. I feel more powerful.

Increased energy -- Fatigue (or maybe it's laziness) sometimes prevents me from happily jumping up to begin exercising. But when I push myself and exert myself and get lost in my exercise routine, my energy returns -- and not just during my workout but for some time afterwards too. Some say energy increases from strength training because it contributes to loss of fat which means we have less to lug around each day.

Burning of more calories -- Weight training raises basal metabolism which causes more calorie burning over a 24-hour period of time. Calories even burn during sleep as a result of weight training.  For every additional pound of muscle you gain, your body burns 50 extra calories every day -- 50 more calories than the few hundred that might burn from aerobic exercise. Research shows that regular resistance training can increase your Basal Metabolic Rate by 15%. So for someone who burns 2000 calories per day, that's upwards of 300 extra calories burned every single day. 

Decreased onset of illness -- Weight training can reduce the risk of adult onset diabetes and the risk for developing colon cancer and can improve the functioning of the immune system and the efficiency of the heart. It decreases the risk of low-back injuries, decreases resting blood pressure, increases good cholesterol (HDL), and improves posture. The list goes on -- and so does healthy living if weight training becomes a way of life. As a young person already having experienced a life-threatening illness, this comforts me.

Prevention of osteoporosis -- My recent bone density test revealed that I am not at this moment at risk for developing osteoporosis. I don't want this to change. Strength training can help me maintain this status because it can significantly increase bone mineral density -- which is important because we naturally lose bone density as we age. Strength training helps protect against osteoporosis. And age should not be a deterrent. Individuals who begin training late in life -- at age 65, for example -- can restore bone loss.

Improved outlook on life -- As a result of toning and shaping my body, burning calories, enjoying greater strength and energy, and working toward a disease-free future, weight training gives me an improved outlook on life. And weight training has recently been reported to significantly improve the quality of life of women recently treated for breast cancer. A May 2006 study indicates six months of twice weekly exercise was enough to improve the overall physical and emotional condition of patients.

Twice weekly is my weight training goal. I will continue to walk and run -- and bike on occasion too -- but strength training will be my priority. Because health is a priority.

During my chemotherapy for breast cancer, I received the drug Adriamycin. Adriamycin is toxic and harsh and so powerful that when it makes contact with the skin it can cause a severe burn. How this drug cycled through my body without singeing my veins, I am not sure. Somehow, I survived it and can think back on this drug that is often called The Red Dragon.  It is wicked and fierce and unkind -- yet lifesaving as well.

The word dragon conjures up various images for me. I can clearly visualize the red liquid that dripped into my body many months ago with the purpose of attacking cancer cells. I also picture toy action figures that often cover my living room floor -- my five-year-old has a current love for dragons, and we have all shapes and sizes at our house. And lately, when I think of dragons, I see women in boats -- powerful women practicing the ancient sport of dragon boating.

I know women who participate in this sport through Team Survivor -- a group that provides free opportunities for physical fitness for women with cancer. And I just learned about Hope Afloat, Philadelphia and Pennsylvania's first breast cancer survivor dragon boat racing team.  With a mission of challenging their limits and not limiting their challenges, these women strive to awaken the dragon within through hope, support, and adventure.  This floating support group has been in existence since 2001 and welcomes all women with a history of breast cancer. Weekly practice, monthly meetings, and racing keeps these women in good shape and in good spirits. Go team!

Shannon Harken wrote an essay to nominate her mother, Sue Myers of Pleasantville, Iowa, as the most amazing mother in the world because of her mother's zest for life and the positive example she set while battling breast cancer. Of the more than 14,000 Mom's the Word essay submissions, Kohl's unveiled the ten most amazing role model mom finalists of the contest and Harken's essay about her mother placed Myers in the top ten moms of the year. Ultimately, America will vote to decide who will be this year's number one amazing mom. All ten essays are featured at Kohl's, where you can vote for the essay and mother you feel best deserves to win.

The role model with the most votes will earn a $5,000 shopping spree, a style transformation, and will be escorted by Daisy Fuentes on a trip to Fashion Week in Los Angeles. In addition, Kohl's and Fuentes will honor the grand prize winner during a ceremony in her hometown on May 13. All mothers are amazing, but I went and voted for Myers. Knowing what she has been through by way of the fact I am a breast cancer survivor and I know what I went through -- I would like to see her win and enjoy a day of special recognition, pampering and fun. Voting ends May 8. Shannon's essay about her mother Sue is cute. It's number #2. Go here to vote.
