It's already been established that type 2 diabetes increases the risk of pancreatic cancer. And now, research indicates there is also a link between type 1 diabetes and this type of cancer.

The risk is relatively small -- but still, those with type 1 diabetes have a likelihood of developing pancreatic cancer that is twice as high as in non-diabetics. This is similar to the risk those with type 2 diabetes face.

There are many theories about the link between diabetes and pancreatic cancer, and this research -- published in the British Journal of Cancer -- helps narrow the scope of the theories.

For example, one researcher says the study rules out "a cancer-inducing role of the insulin-producing beta-cells in the pancreas, because in type 1 diabetes these cells have largely or entirely been destroyed."

Experts say people with diabetes should focus their attention on the most common complications of diabetes such as heart disease, eye disease, and kidney disease and not on the very small risk of cancer. In the whole scheme of things, pancreatic cancer is a rare disease -- and even twice the risk is not very significant.

Double the hormone, double the risk. Or so says one study of older women who take hormone pills. When estrogen and testosterone are combined, women face twice the chance of getting breast cancer, according to a study of more than 70,000 nurses. This type of combination therapy may help with mood, libido, and bone density -- but the possible risk of breast cancer may just outweigh these benefits. These findings, published in Monday's Archives of Internal Medicine, add to the evidence that certain types of hormone supplements -- like estrogen-progestin pills -- increase risk of breast cancer, strokes, and heart attacks in women. Other research points to a link between breast cancer and high natural levels of testosterone.

Women's natural levels of estrogen and testosterone decrease with menopause. Use of supplements has climbed over the past 24 years, perhaps putting more women at more risk. Estrogen-testosterone pills are sold under the brand names Estratest and Estratest H.S. and appear on a Washington-based advocacy group's "Worst Pills" list because of breast cancer risk.

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.

Men tend to think differently from women about their bodies and health, with specific attitudes towards lifestyle behaviors involving smoking, alcohol and diet. Coupled with the fact that significant numbers of men do not seek medical care or participate in early cancer detection practices, and men are twice as likely as women to die from cancer. The Men's Health Forum, MHF, wants health professionals to act to develop cancer prevention policies that take men into account. The MHF said that their analysis showed current cancer prevention policies and programs are not working for men.

As a result of these study findings, the MHF has formed a partnership with the publishers of Haynes car manuals to produce a new cancer guide in an effort to get men to take more of an interest in their health. The guide, designed in the same way as a car manual, provides information on how men can keep their bodies running like a finely-tuned engine. "Men are used to using information presented in this format. The body as machine metaphor resonates with the way many men think about health issues," stated Dr Ian Banks, MHF president and author of the manual. While the concept introduces an element of humor, the subject is serious business. MHF reports 134,000 men are diagnosed with cancer every year in the UK, with 80,000 dying of the disease.
