Tears are streaming down my face. I can't stop them, and I'm not sure I want to. In a way, I want to feel the tragedy of life lost to cancer because it makes it all real. It makes it personal. It makes me realize the same tragedy could happen to me, my family members, my friends. It makes me want to make a difference even more now that I've seen the chilling pictures of a young woman dying of cervical cancer than moments earlier when I was moved mostly by my own breast cancer journey.

I first read about Heather Lyn Martin on the JANE magazine website, home of a beautifully-written story -- I Hate Tumors -- by Sara Lyle, long-time friend of Heather and senior editor for JANE, a publication for 20-something women. Sara's words powerfully depict the life and death of her friend, stricken with a disease she was sure she would beat. So sure, in fact, she asked Sara to help tell her success story.

Sadly, Heather never got to tell much. Because she died much too soon, at the age of 28. So Sara told the story through her own words and photos -- the same ones responsible for my tears -- and has just recently written a second essay, one year after her first story started reaching young people everywhere.

Sara wrote Why I Still Hate Tumors after inspiring many young women to open their eyes to the realities of a deadly disease. Her words serve to raise awareness about the dangers of cervical cancer -- and the HPV virus that causes it -- and to point women in the direction of resources critical for preventing and conquering the disease.

Sara, because of the death of her dear friend, is saving lives with her message. And she just may save yours.

To see all that Sara has to offer in the fight against cervical cancer and other hated tumors, visit her I Hate Tumors website.

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.

It may be possible to learn happiness -- like we might learn to cook or learn to dance -- by merely taking a class. Some refute this idea and believe you can't actually pursue happiness. You either have it or you don't. But some psychologists are embracing a whole new approach to psychology -- they call it positive psychology -- and they say it focuses on training the mind to focus on the past as very positive. It's completely different from traditional psychology where time is spent trying to determine why someone is so horribly sad. This movement, invented by University of Pennsylvania psychologist Martin Seligman in 1998 when he was president of the American Psychological Association, provides a scientific validated set of exercises -- known as interventions -- that lead happiness seekers to their ultimate destination.
