Mixing antioxidants and sun exposure can be dangerous to your health. A new study, published in the September issue of The Journal of Nutrition, details a French study revealing that antioxidant supplements won't protect women against skin cancer -- and they may actually increase the risk of developing the disease.

A team of French researchers assigned almost 7,900 women and more than 5,100 men to take either an oral daily capsule of antioxidant or a placebo that looked the same. The antioxidants included low levels of vitamins C and E, beta-carotene, selenium, and zinc. What they found: the incidence of all skin cancers was higher in the group of women who took the antioxidant.

While there is one limitation to this study -- it did not take into account sunscreen use and its effect on the use of both antioxidants and the sun -- it does serve as another reason to stay out of the sun.

My sister has skin cancer -- the basal cell variety. She has two spots, both on her chest, each one scheduled to be surgically removed in a few weeks. If it were me with this new diagnosis, I'm sure I'd be freaking out, maybe because I've already had breast cancer and tend to panic about any cancer or maybe just because I'm a worrier by nature. But my sister is taking her cancer news in stride, and I am too -- because now that I've done a little research, it seems this type of cancer is pretty easy to beat.

Here's a little refresher lesson on the skin: The skin is the largest organ in the body, and is made of three layers -- the epidermis (top layer), dermis (middle layer), and subcutis (deepest layer). For the purpose of this post, let's focus on the epidermis.

The epidermis has three layers -- an upper, middle, and a bottom layer. This bottom layer is comprised of basal cells. This is where basal cell cancer begins.

OK, women of the world. Grab some paper and a pen and jot down this list of seven check-ups every woman needs. Don't just write them down, though. Make sure you take action on each and every one. They might just save your life.

1. Start with your weight, height, and BMI (body mass index). The scores you get on these simple tests are important because many conditions and diseases are associated with being overweight or underweight.

2. Check your blood pressure, and find out where you stand because hypertension is a disease with no symptoms. High blood pressure puts you at risk for cardiovascular disease -- but there are very effective treatments for this condition.

Vitamin D is one of the latest, greatest hot cancer topics. Why? Well, it seems many of us women are vitamin D deficient. Such a deficiency might be linked to breast cancer risk so it's in our best interest to make sure we get a healthy dose of this vitamin. It's not as easy as adhering to the Dietary Reference Intake (DRI) guidelines, though. Follow them and you'll still come up short -- the Food and Nutrition Board, responsible for setting the DRIs, have not yet updated guidelines in light of cancer concerns. So what's a girl to do?

For starters, we need to understand that for overall health benefits, 1,000 IU (International Units) per day are necessary. The outdated DRI recommends 200 to 600 IU. This is based on preventing only bone diseases like rickets. Second, keep in mind it's safe to take up to 10,000 IU each day. Third, up your intake of this important vitamin. Here's how:

Fatty fish is the best source of vitamin D. But watch out for high mercury levels. Fortified milk is also good. It has 100 IU of vitamin D per eight-ounce serving, but cow's milk been linked to breast cancer risk as well.

I'm a little tired of reading and writing about sunscreen. Maybe it's not the actual reading and writing that has me worn out. Maybe it's the realization that I keep reading and writing about sunscreen yet the information is just not sinking in with the masses of sun-hungry people out there -- according to the EPA, there has been a staggering 1,800 percent increase in malignant melanoma cases since 1930. Recent figures show a shocking rise in skin cancers among those in their 20s and 30s.

The experts at Canyon Ranch are weighing in on sunscreen. So here I go again, with some more about this tiring topic.

• Sunscreen contains unique chemical components which absorb ultraviolet (UV) light. When applied to the skin, the chemical molecules form an invisible, protective layer that repels the penetrating UV rays. It also helps prevent premature aging and pre-cancerous growths.

I did a post back in August of last year about my friend Larissa's journey through breast cancer. Larissa was just recently diagnosed with cancer again. This time it was skin cancer, basal cell carcinoma.

I asked Larissa if she would talk about her experience and how it felt to be diagnosed with cancer yet again. Larissa blogs at Welcome to the Dallehouse.

How did you find out you had skin cancer?

I had a red patch on my face that didn't go away for several months. I kept an eye on it and noticed it was getting larger so I made an appointment with a dermatologist. The dermatologist thought it looked suspicious and did a shave biopsy. The biopsy came back positive for basal cell carcinoma.

I keep thinking about my ongoing negative relationship with the sun, how it burns me time and time again, how I keep trying to fine-tune my approach to dealing with this deadly force. Today, I have arrived at two new thoughts.

1. There was a time when I wanted a tan. I'd accept a burn even, in hopes it would turn to the slightest shade of brown on my pasty white skin. I would search high and low for the sun. I would drive in its direction, bask in its glory, give hours of my day to this crazy pursuit. Somehow, though, achieving a tan -- or burn -- wasn't easy. Sometimes, I'd see some color appear; sometimes my efforts seemed for nothing. It took work, effort, endless amounts of time and while my ventures in sunbathing did sometimes prove successful, there were many times I was left with, well, pasty white skin.

Fast forward to now. Not only do I seek shelter from the sun, but I use sunscreen, sit under umbrellas, and cover up whenever I can. Still, I get burned. It seems if I look in the direction of the sun, with my sunscreen-coated face, it will get burned. Long ago, my bare face only occasionally absorbed the sun. Why the change? Why when I worked not at all at protecting myself was it so hard to attract a golden glow? Why now do I protect myself in all ways possible and still sizzle? I'm wondering if it has anything to do with the chemotherapy drugs that poisoned my body for so long. A dermatologist once told me about a phenomenon called UV recall. The sun and the drugs can react, long after treatment has concluded, and can cause skin reactions. Maybe this is what's happening to me. Just in case, this gives me all the more reason to avoid all contact with the sun.

I'm sad, worried, and frustrated because of what happened to me at the beach this past weekend. I got burned. Really burned.

I thought I did everything right. I applied sunscreen, even had my husband coat my back, shoulders, and hard-to-reach spots with the powerful lotion intended to block the sun's most damaging rays. I sat underneath an umbrella while watching my boys, their own pale bodies slathered in a baby sunblock potion, as they jumped, ran, and bounced in the waves. I reapplied my sunscreen after a short stint in the pool and a stroll on the sand left my skin feeling tender. Still, I sizzled. My back is red, the skin underneath my suit straps white as can be in contrast to the bright color it borders, My chest is red and sore and itchy with bumps.

I feel sick, like I've exponentially upped my risk for skin cancer. As a cancer survivor, I feel particularly vulnerable. I not only fear a return of breast cancer, you see. I fear other cancers too. My ultra white skin already puts me at risk for sun damage. My past forays into sunbathing don't help. What happened this weekend, I'm afraid, makes things worse.

Who knows which pieces of cancer information floating around out there are actually true? I don't. Do cell phones cause cancer? Some say yes, some say no, I say I'm confused! Luckily, I happened upon this Discovery Health article that highlights a variety of myths and then offers the lowdown on each one. Here are seven of them:

Myth #1. There is currently a cure for cancer, but the medical industry won't tell the public about it because they make too much money treating cancer patients.

Chalk this up to urban legend. And consider this: doctors, laboratory scientists, and their families and friends die of cancer at the same rate as everyone else in the United States. How about this: medical breakthroughs happen all the time and are quickly applied. Think about antibiotics and vaccines -- like the polio vaccine -- that have transformed health care. How about this? Not too long ago, less than one in 10 kids with leukemia survived 10 years. Now, the cure rate is nearly 80 percent. Seems like progress to me.

Last Tuesday night, I watched Greta Van Susteren of Fox News' On The Record as she interviewed Brittany Lietz, Miss Maryland 2006. Greta asked Brittany what her Miss Maryland job entails. Brittany told Greta her full-time job is to represent her platform -- skin cancer.

Brittany didn't choose just any topic for her platform. She chose one that is entirely personal.

Skin cancer has left more than 20 scars on Brittany's body. One, on her back, marks the site where a stage two melanoma was removed when she was just 19 years old. It presented as a mole, a little smaller than a nickel, she says. In all likelihood, the cancer was caused by two years of tanning bed use. Brittany says she probably tanned every day for two years. Her pursuit of bronzed skin began when she was 17 and wanted a tan for her prom. It ended after doctors told her she had cancer.

When I describe the cancerous lump I found in my breast almost three Novembers ago, I explain that it felt like a hard, frozen green pea. The port used for chemotherapy infusions and sewn under the skin near my collarbone? It looked like a bottle cap popping up for all to see. My kids called it a stone. I had to numb my skin prior to treatments -- the needle inserted into the center of the port was just too big and painful. I slathered on my numbing lotion prior to each dose of drugs. Imagine the size of a quarter. I used twice this much. I was wimpy.

There's something about visual descriptions that help us remember some of the more important things in life. Here's a good one:

According to Jeffrey Dover, MD and associate clinical professor of dermatology at Yale School of Medicine, we must not skimp when we apply sunscreen. How do we know if we are cutting ourselves short? We should be using a shot-glass full of sun protection to cover our bodies. Anything less is not enough.

Each year more than 211,000 American women learn they have breast cancer. Breast cancer is the most common type of cancer among women in this country other than skin cancer. But breast cancer is not just a cancer that strikes women. Each year 1,700 men in this country will learn that they have breast cancer. About 500 men will die from the disease. So it is just as important for men to know the signs they might experience if developing breast cancer and act on them immediately with a visit to a doctor. It is important to know your body and to recognize changes that might be taking place.

Signs of Male Breast Cancer

1. Abnormal lumps or swelling in either the breast, nipple, or chest muscle
2. Skin dimpling or puckering
3. Nipple retraction (turning inward)
4. Redness or scaling of the nipple or breast skin
5. Nipple discharge

A new website assesses the effectiveness and safety of almost 800 sunscreens. The suncreen screening site was put together by the Environmental Working Group and gives detailed information about many sunscreen products. It also groups them by the types of harmful rays they're meant to protect against.

SPF numbers on sunscreens only cover UVB, the type of rays most responsible for burns. UVA is far less responsible for burning, but still can raise skin cancer risk. Only one sunscreen in five has effective UVA protection. There are ingredients that protect well against UVA, but sunlight can break down and make them ineffective if they are not formulated well.

Watch out for the commonly misleading claims -- all day protection, waterproof or chemical free products. You can check the website for sunscreens that are recommended and ones to be avoided.

The American Cancer Society estimates that approximately 16,600 new cases of myeloma are diagnosed each year in the United States. Bone pain is the most common early symptom of myeloma. Most patients feel pain in their back or ribs, but it can occur in any bone. The pain is usually made worse by movement.

Patients fatigue more easily and often feel weak. They may also have a pale complexion from anemia which is a common medical problem for patients with myeloma and may contribute to the fatigue. If the disease progresses, the concentration of normal cells in the blood may also decrease. Headaches, bruising, nose bleeding, gastrointestinal bleeding, and tingling or numbness in extremities are all symptoms of myeloma.

Patients may have repeated infections because antibodies to invading viruses, bacteria or other disease agents are not made efficiently of in adequate amounts. Urinary tract, bronchial, lung, skin, or other sites of infection may be the first sign of the disease. In addition, recurrent infections may complicate the course of the disease.

For many young people, the risk of wrinkling is a bigger tanning deterrent than the risk of skin cancer. How's that for some misplaced worry?

Now if the wrinkle-worry gets these youngsters to stop tanning, then I'm happy. Still, it amazes me that warnings about skin cancer still are not taken seriously.

"We don't know for sure, but there's some suggestive evidence that young people are more influenced by thinking about themselves getting old faster, than thinking about themselves getting a skin cancer," says one doctor.
