There is still time to register, volunteer or donate for the Avon Walk For Breast Cancer which will take place in several cities across the United States -- Los Angeles, New York, Charlotte, Washington DC, Boston, Chicago, Denver, and San Francisco. This weekend walk that extends over two days and 39 miles will take place as soon as September 2006 in Los Angeles and as late as July 2007 in Denver. This walk, designed to benefit medically underserved women and men -- allowing them treatment they otherwise would not receive -- also funds research teams as they continue their quest for a cure. With Prevention magazine as the national sponsor and other official sponsors such as Reebok, the Avon Walk For Breast Cancer has made quite a mark already. This year's Chicago walk raised a record-breaking $8.2 million and tracked the steps of more than 3,500 participants. There is no better proof than this -- in my opinion -- that walking can make quite a difference.

I woke yesterday morning to voices on the Today Show telling me that the use of hair dye is linked to incidences of lymphoma -- a general term for a group of cancers that originate in the lymphatic system. I know I've heard in the past about the possible link between cancer and the chemicals that add color to hair -- but the connection has never been revealed as very strong and the topic did not ever apply to me so I filed the information in the back of my mind. But now, it appears the link may be stronger than originally thought -- and I recently dyed my own post-chemo brown hair -- so I listened more intently this time and learned about the study that implies that touching up my roots may not be a wise practice.

The results of a European study, appearing in the July 1 issue of the American Journal of Epidemiology, reveal that roughly 10 percent of lymphomas in women could be caused by the use of hair dyes. The data suggest a small increase in risk -- and clearly more research is necessary -- but what researchers have found is that for the women who have dyed their hair more than 12 times, the risk is highest. And those who colored their locks before 1980 have the greatest risk. Since 1980, chemicals thought to be cancer-causing were eliminated from dyes -- although it is still not definite whether or not current hair dyes are risk-free. It is definite, say researchers, that further study of this topic is important. In the meantime, I think I will let my artificial reddish chestnut hues fade away while I enjoy the plain brown hair that covers my once-bald scalp.

Australian singer Kylie Minogue said in a recent interview that she and her family fell to pieces upon hearing her diagnosis of breast cancer this past May. Since that time, she has had surgery and chemotherapy and she currently receives treatment to prevent a recurrence of the disease. And she is now picking up the pieces of her life and is rebounding from the once disbelief that her life would take a detour. Last week, she attended her first public appearance since her illness -- at Elton John's White Tie and Tiara ball -- and she is renaming her Showgirl tour, which was canceled after her cancer battle began. Now the Showgirl Homecoming Tour, Minogue is set to return to performing. Her concert promoter says she will take it slow -- to accommodate her off and on again fatigue -- but she will return with the vigor she is known for. Minogue says she feels like she has a new chance at life now. And she will talk all about it on July 16 when her interview is aired on Britain's Sky News.

Summertime, watermelon, and the 4th of July all go hand and hand. This fruit seems to be a tradition in almost every back yard BBQ on this holiday. In July this fruit is abundant in every roadside fruit stand, farmers market and grocery store. Watermelon contains the phytochemical lycopene, one of our colorful disease preventing cartenoids that is most known for in tomatoes. That is why they are both red. Studies have shown that a cup and a half of watermelon contains about 9 to 13 milligrams of lycopene. On average, watermelon has about 40 percent more lycopene than raw tomatoes.

The vegetable Jicama has a crunchy texture like that of water chestnuts but with a sweet taste. It is easy to just peel, slice and serve raw. It is a good source of vitamin C as well as dietary fiber aiding in fighting colon cancer.

I like to use these two naturally sweet items in a nutritional salad packed with vitamins, taste, fiber and cancer fighting lycopene.  Here is my recipe.

Vicki's Watermelon & Jicama Salad
1 head Romain lettuce.
1 head radichio
4 tangerines peeled and segmented
1 piece jicama, peeled, cut into 1/2 inch thick slices about 2 inches long
1 watermelon   
1 pack feta cheese
1/4 cup dried cranberries 
1/4 cup toasted sunflower seeds

Vicki's Citrus Vinaigrette
4 tablespoons fresh orange juice
2 tablespoons fresh lime juice
1 tablespoon extra virgin olive oil
1 tablespoon honey
1 teaspoon red wine vinegar
1 teaspoon rice vinegar
1/2 teaspoon salt
1/4 teaspoon freshly ground black pepper
Whisk together all ingredients.

Tear lettuce and radichio apart rinse well and shake dry. Lightly tear apart into bite size pieces and place the leaves around on individual salad plates so that the texture and colors of the salad are mixed. Scoop out 5 to 6 balls of the watermelon with a melon baller and place onto the center of the salad plates. Then place wedges of the jicama and tangerines around the watermelon. Sprinkle with cranberries, feta cheese, and toasted sunflower seeds. Lightly drizzle with citrus vinaigrette and serve. Will serve 4 to 6 depending on how large you like your salads.

During the warmer months, it's all about the barbeque. Of course, we have been known to barbeque during winter in the snow, but for the purpose and timing of this discussion, when it's summer in the northern hemisphere, almost everyone fires up the barbeque. Because research has suggested that barbequing meats can increase cancer risks associated with charred food, the Dana Farber Cancer Institute offers these tips to grilling red meats, poultry and fish safely:

• Choose lean cuts of meat. Trim excess fat and remove the skin.
• Avoid thick marinades, as they increase charring. Use thin marinades that have vinegar or lemon as one of the ingredients.
• Flip burgers once every minute.
• Place food at least six inches away from the heat source.
• Line the grill with perforated aluminum foil to prevent drippings from creating smoke.
• Cook on cedar planks. 
• Consider kabobs. They take less grilling time.
• Consider grilling your favorite vegetables instead of just meat.
  

These tips are followed with some common sense advice. If you avoid charring all the red meat, poultry and fish you barbeque, the expert nutritionists at the Dana Farber Cancer Institute state that your risk of getting cancer from grilling food is extremely low. According to the information, not eating a diet rich in fruits and vegetables is a bigger risk factor for cancer than eating the occasional barbequed meats. I like common sense perspective.

It's Fourth of July weekend, and this year is a long one! Traditionally, celebrations for the Fourth of July include picnics, camping, boating, hiking, backyard barbeques, free concerts in the park, a stroll by the river, a day at the beach. Basically, most activities this weekend involve being outdoors enjoying good times and the warm summer sun.

Before you, friends and family head out the door, here is a sampling of posts we have done about spending time in the sun -- skin cancer facts -- and tips on practicing sun safety.

• Skin cancer prevention kits for kids.
• Shading kids from the sun.
• Pediatricians need to educate parents about sun exposure risks.
  

• Skin cancer myths debunked by dermatologists.
• Global warming skin cancer warning.
  

And the sun, with the right exposure, is not all bad.

• Vitamin D: sunshine as cancer prevention.
  

For a complete listing of the posts regarding skin cancer and sun safety, visit The Cancer Blog's melanoma and skin cancer categories. The Fourth of July is a great time for celebration of our freedoms and all the wonderful warmth and brightness of summer days. Enjoy! every minute but be sun-wise and sun safe.

Dimericine, a lotion created to be used the day after a sunburn to protect against some forms of skin cancer, might win FDA approval in the next two years. It's not a magic bullet that allows sun worshippers to return to the old ways of tanning without consequence. Spend too much time in the sun and wrinkles are inevitable. The pain of a sunburn will still hurt even using this new cream. And skin cancer is still a risk -- perhaps just less so.

Dimericine is more of an emergency morning after measure, if you spend more time in the sun than you should the day before and have a burn as a result, or you missed a spot when applying the sunscreen lotion and were not aware until it was too late to prevent the sunburn. The cream will repair some of the damage to the skin a sunburn causes. If the cream is approved, and becomes available, experts still recommend that all the sun safety rules be followed when spending time in the sun. Sunscreen, wide-brimmed hat, sunglasses, long sleeves, seeking shade and staying out of the sun during peak hours between 10 am and 4 pm.
