Britney Spears, fresh out of rehab and back in the spotlight, is explaining why she publicly shaved her head back in February, following a rampage of bizarre behavior.

Think about this:

A friend of Spears says the pop star shaved her head as a tribute to her aunt who died from cancer. The pal states Spears was definitely suffering from postpartum depression at the time and the bold hair maneuver was an act of solidarity.

"Britney's aunt had just died of cancer," says this friend. "She was feeling very guilty because she hadn't been there with her, she was overwhelmingly depressed and she shaved her head in solidarity."

Cancer sent me into a state of depression. And it took more than a year of counseling and treatment with an anti-depressant to bring me back to a balanced and healthy level of functioning.

My type of depression -- the kind that shows up just after a cancer diagnosis -- is not uncommon. And neither is the spillover that depression can leave on the children of moms depressed because of their disease.

A study at the University of Pittsburgh -- the first to examine the relationship between children's concerns and a mother's cancer-related depression -- found children of depressed breast cancer patients were more likely to be concerned or anxious about their mother's cancer and about how the disease affects their families.

It's not surprising that kids worry about their moms during times of illness. What startled researchers, though, is the fact that children's' anxieties extended to concerns about the entire family.

The results of this study, funded by the National Cancer Institute, has clear implications. As a society, we need to think about how depression affects whole family units. Oncologists must learn to spot depression early and must swiftly assist women in finding appropriate treatment. And parents should talk openly about cancer and it's emotional side effects with their children in an effort to protect them from withdrawing, hiding their concerns, and suffering in silence.

Most estimates indicate nearly one quarter of women diagnosed with breast cancer have young children. And about 100,000 kids will be affected by a cancer diagnosis this year alone.

Physicians now have a tool that can diagnose depression in cancer patients. Patients sometimes will need additional treatment to enable them to cope with their cancer more effectively.

The problem has been that doctors might have a hard time telling what patients actually have clinical depression. The patient may be just showing normal signs of sadness, feelings which commonly result from being diagnosed with cancer.

A team from the University of Liverpool's Division of Primary Care has created this method of testing called Brief Edinburgh Depression Scale (BEDS). What this test does is assess the cancer patient's mental condition with a six-step scale. The test includes questions on worthlessness, guilt and suicidal thoughts.

Professor Mari Lloyd-Williams, lead researcher says "The effects of depression can be as difficult to cope with as the physical symptoms of a terminal illness such as cancer. Patients often feel useless, that they are to blame, and even experience suicidal thoughts during cancer - these are all signs of depression but rarely elicited."

The clinical trial that was conducted included 246 patients with advanced cancer. Twenty-five percent of those patients were shown to have depression that had previously not been diagnosed.

Survivorship is the new cancer buzz word -- and what an important word it is. Once left to each individual to define, manage, and transcend, survivorship is now recognized as a distinct phase of cancer recovery -- just as important, and maybe even more so, than diagnosis and treatment.

Linda Griggs, a 13-year breast cancer survivor, clearly remembers the day her chemotherapy ended. With her therapy complete, her hair growing back, and her medical team sending her off to have a nice life, she thought she'd be fine. But she wasn't.

Three months after her last dose of chemotherapy, Griggs was depressed, consumed with worry about how her cancer might come back. And she realized that the end of treatment is not really the end. It's just the beginning.

Griggs told her doctor about her anxiety, about how she was just trying to make it to her next three-month-check up. When her doctor told her, "that's not living," something clicked for Griggs who instantly decided to start living -- really living.

Surviving is about self-nurturing, says Griggs, who has created a kit to help others survive cancer. On her website, she writes that there are a couple of other breast cancer survivor kits out there -- containing tissues, herbal teas, meditation tapes, medical appointment books, and breast cancer resource materials.

"This is not that," she says of her kit that focuses on the emotional upheaval cancer creates.

Griggs' kit is full of hands-on creative materials -- like an inner child notebook, complete with magic markers for journaling and expressing emotions. If you're angry, you can write down angry thoughts. If you're sad, write what makes you sad. Save the pages, tear them up, burn them, do what you wish -- but allow your emotions to flow, Griggs says.

The kit also includes a wooden box with instructions on how to create a healing shrine, a copy of Griggs' non-fiction account of the first five years of her cancer journey, and so much more.

Griggs, who also teaches healing workshops, guides others to understand cancer as a hero's quest. She says when something happens to us -- death, divorce, disease -- we are receiving a call to adventure. All bet's are off. We must start fresh, gather our spirit guides, collect ourselves, dive into the underworld, overcome, and then emerge full of wisdom of growth.

Griggs has emerged -- full of her own wisdom and growth. She is a hero -- on a quest to help others survive a disease that threw her way off track for way too long.

Need one more reason to calm down? Take it all in stride? Walk on the sunny side of the street?

Boston's Harvard School of Public Health researchers have one more reason for you to let it all go because a new study has shown that being angry and hostile contributes to diminished lung function. During the eight-year study, 670 men -- aged 45 to 86 -- were tracked. Men who exhibited sustained levels of anger and hostility suffered from accelerated lung deterioration.

This study supports further evidence that emotions, and the mind-body connection, have a biological effect that can lead to better or worse health. Negative emotions are known to contribute to heart disease and other diseases. Experts explain that "stress-related factors are known to depress the immune function and increase susceptibility to or exacerbate a host of diseases and disorders."

Grab your coat and get your hat
Leave your worries on the doorstep
Life can be so sweet
On the sunny side of the street -- Louis Armstrong On The Sunny Side Of The Street

One of the first books I read after my breast cancer diagnosis was issued in hardback in 1986 -- 20 years ago -- and then was published again and reissued and reprinted in 1990, 1998, and 2002.While the cover has changed and perhaps some wording too, the message in this book -- Love, Medicine, & Miracles by Bernie S. Siegel, M.D. -- remains unchanged.  And it is inside the covers of this book that I keep learning that I have the capacity and power to become an exceptional patient -- despite the fact that I've been faced with a life-shattering diagnosis of cancer.

Traditionally, the medical community has focused its resources on cancer treatment in saving lives. Rather recently, there is a growing trend and interest in cancer prevention. As a result, there is more awareness and conversation about the causes of cancer, and the ways to prevent cancer. Although less than ten percent of the population links cancer risks to obesity, one of the leading lifestyle factors that is known to raise the risk for cancer is obesity. The Rudd Center for Food Policy and Obesity at Yale University conducted an online survey that revealed rather startling results. When it comes to obesity, half of the people who responded to the survey said they would give up a year of life rather than be obese. In addition, they indicated they would walk away from their marriage, give up the possibility of having children, be depressed or become alcoholic rather than be obese.

It gets more extreme. Five percent said they'd rather lose a limb than get fat, while four percent said they'd rather be blind than be overweight. Of those who responded, three percent were underweight, 41 percent were normal weight, 21 percent were overweight, 21 percent were obese and 14 percent were very obese. There is something desperately sad about the truth of how we feel about being fat. Being overweight is not good. Maintaining a healthy weight is good. However, it seems being fat is dangerously weighted in more than our concern for health. The psychological pain appears profound for many even considering the possibility of being overweight and illustrates the lengths people would be willing to go to be thin. Alcoholism? Loss of limb? Blindness?
