Want to reduce your risk of skin cancer? Wear sun screen, of course. But two new studies suggest that choosing your relatives carefully could also be helpful.

One found that having an identical twin with melanoma increased a person’s own risk of developing the disease much more than having a fraternal twin with this type of skin cancer. The other found that having a sibling or parent with one of several different types of non-melanoma skin cancer increased risk as well.

Several studies have suggested melanoma and other skin cancers run in families, but it can be difficult to tease out the difference between the influence of genes and environment. In the Australian study, Dr. Sri N. Shekar of the University of Queensland in Brisbane and his colleagues attempted to do so by looking at twin pairs in which at least one sibling had been diagnosed with melanoma.

They searched through thousands of cases of melanoma reported in Queensland and New South Wales and found 125 twin pairs. In four of the 27 identical twin pairs, both had melanoma, while three of the 98 fraternal twin pairs had both been diagnosed with the deadly skin cancer.

Based on these numbers, having an identical twin with melanoma increased a person’s own risk of the disease nearly 10-fold, while melanoma associated with having a non-identical twin with the disease was roughly doubled.

This suggests, the researchers say, that some of the increased melanoma risk can be attributed to genes, in particular interactions between genes. They estimate that genes account for about half of the differences in risk between two people.

In the second study, Dr. Shehnaz K. Hussain of the University of California Los Angeles and colleagues looked at the Swedish Family-Cancer Database to gauge the risk for several types of skin cancer among siblings and children of people diagnosed with these diseases.

They found that people with a sibling or parent diagnosed with some types of skin cancer were more likely to develop skin cancers of various types, not just the ones their relatives had. When tumors occurred at parts of the body more likely to have been exposed to the sun (such as the face, compared to the torso), the familial risk was stronger.

Based on the findings, Hussain and colleagues conclude, a person’s family history can be used to gauge their own skin cancer risk, and genetic studies could be a useful way to identify potential targets for treating or preventing the disease.

US scientists have found a gene that drives the growth and survival of the most dangerous form of skin cancer.

Every year, more than 7,000 UK people are diagnosed with malignant melanoma and about 1,700 die from it.

Experts have warned that annual UK rates could treble by 2035 based on current trends.

The gene discovery, described by the Dana-Farber Cancer Institute team in the latest edition of Nature, could point to new treatments, they hope.

DNA error

Dr Levi Garraway and colleagues used a high tech procedure that focuses on the building blocks of individual genes to identify areas of DNA containing mistakes in tissue samples from patients with malignant melanoma.

By comparing these with results from non-cancerous tissue samples, they pinpointed one genetic error that appeared to be critical for tumour growth, particularly in some of the most advanced cancers that had spread or metastasised.

This was an abnormal replication or amplification of a gene called MITF. Some tumours had as many as 13 extra copies of MITF.

Co-researcher Dr William Sellers said: “By pinpointing the abnormally multiplied MITF oncogene, we may be able to develop better diagnostic and prognostic tools as well as provide a target for highly specific therapies for metastatic melanoma patients who have this overcopied gene.”

Treatment hope

The abnormal amplification of the MITF gene was associated with other genetic changes as well. They included mutations in a gene previously found in malignant melanomas, called BRAF, and silencing of a gene that normally keeps cells from dividing too rapidly and causing cancer, called p16.

Dr Sellers said: “We might be able to treat these metastatic melanomas by targeting the MITF gene or protein, alone or in combination with drugs that block BRAF.”

Ed Yong, Cancer Information Officer at Cancer Research UK, said: “Excessive sun exposure causes most cases of melanoma. But faults in some genes can influence our risk of this disease, and our chances of surviving it.

“Identifying these genes can suggest new ways of preventing or treating this cancer.”

We all know what caffeine can do for our moods in the morning, but it’s also increasingly celebrated in the dermatological community for its impact on the skin.

For years, caffeine’s ability to quickly and effectively constrict blood vessels has made it a valued topical ingredient, particularly in products designed to minimize facial flushing. For that reason, caffeine can be a tremendous boon to those who suffer from rosacea, which is essentially caused by frequently dilated blood vessels that lose their ability to contract. La Roche Posay Rosaliac products, for example, are a great anti-inflammatory option for anyone who suffers from rosacea or facial redness. Topix Replenix CF Anti-Photoaging Complex SPF 45 is another excellent, well-rounded product that offers a blend of powerful antioxidants, caffeine, and sunscreen.

Caffeine’s blood vessel-constricting benefits also make it a go-to ingredient in many eye creams (like MD Formulations Moisture Defense Antioxidant Eye Crème, for example), as it can quickly minimize redness and puffiness.

In addition to its anti-inflammatory benefits, though, caffeine is starting to get attention because it may prevent skin cancer as discussed in the February issue of the Journal of Investigative Dermatology. Consumption of caffeine has been shown to be associated with lower incidences of nonmelanoma skin cancers in several epidemiological studies (Jacobsen et al., 1986; Hakim et al., 2000; Abel et al., 2007; Rees et al., 2007).

One study of over 93,000 women showed that drinking coffee decreased their risk of skin cancer. Other research suggests that both oral and topical caffeine may offer powerful anticarcinogenic benefits. I personally use Replenix CF cream with caffeine twice a day.

So whether you drink it iced or hot, or apply it topically, caffeine seems to have a benefit for the skin. Just a couple words of caution, though: Caffeine is dehydrating, so be sure to follow your coffee or tea with plenty of water. And if you’re prone to facial flushing, hot beverages can cause redness; consider enjoying your caffeinated beverages over ice.

You can invest half your paycheck in serums and creams - even splurge on dermal fillers and pricey facials - but none of it will get you far without a skin-friendly diet.

Of course, your skin (and the rest of you, for that matter) is best served by a well-rounded diet, including healthy fats, sufficient protein, and lots of fruits and vegetables. But there are a few nutritional standouts that make particularly important contributions to strong, glowing skin:

1. Fish: Fatty fish like salmon, tilapia, and cod are rich in omega-3 fatty acids. And that’s a good thing, because our bodies cannot produce those essential lipids naturally. By adding omega-3s to your diet, though, you can bolster your skin barrier - that is, the layer of lipids that holds onto moisture and keeps irritants out.

There is even evidence that the skin-strengthening effects of omega-3s can improve chronic skin conditions like rosacea and atopic dermatitis, but more research is necessary to confirm that link.

Furthermore, many types of fish (like, once again, salmon and cod) are rich in vitamin D - as dermatologists increasingly emphasize sun avoidance, we also need to emphasize the importance of finding other sources of this vitamin, which is produced during sun exposure.

Don’t eat fish? Many eggs are now fortified with omega-3 fatty acids, and plant sources include flax seed and flax seed oil, walnuts, pecans, and hazelnuts. And a daily vitamin D supplement is a good idea for vegans and meat-eaters alike.

2. Green Tea: It’s inexpensive, easy to add to your routine, and one of the best-researched and most powerful antioxidants around. That’s why green tea is my go-to antioxidant: I drink at least three cups a day to fight aging and inflammation. Some studies even suggest that the antioxidants in green tea reduce one’s risk of skin cancer. So put down that soda and start drinking your way to healthier skin!

3. Broccoli: Rich in vitamins A, C, and K (among many other nutrients), this veggie does more than its fair share of nutritional work. Vitamin A decreases oil production, vitamin C is a powerful antioxidant, and vitamin K can help prevent bruises. So whatever ails you, this green wonderfood might be just what the doctor ordered.

4. Safflower or Sunflower Oil: Omega-3s get a lot more talk, but omega-6 fatty acids - like the linoleic acid in these two oils - are also important for healthy skin. Like omega-3s, they help prevent dry skin and inflammation; they’re also essential for the formation of prostaglandins, hormones that keep all the cells of the body functioning well.

While many diets are actually quite high in omega-6s - sometimes even too high - the key is to get the good ones and not unhealthy versions, like hydrogenated oils. So try sautéing your salmon or broccoli in a little safflower or sunflower oil and double those skin-soothing benefits!

5. Almonds: When it comes to boosting skin’s defenses against aging, inflammation, and even skin cancer, antioxidants are so important that I’m going to add another to my list: A handful of almonds every day boosts your levels of vitamin E, one of the most important antioxidants for skin health. Studies also suggest that consuming vitamin E orally can increase the levels of this moisturizing vitamin on your skin’s surface - great news for anyone prone to dry skin.

Cancer is the second most prominent killer of Americans—second only to heart disease. But there’s increasing scientific evidence that certain supplements and foods reduce risks from a variety of cancers.

Of course, deciding what supplements to take and food to consume isn’t a simple task. There’s a bewildering amount of new and sometimes conflicting information on cancer-preventive food and supplements. And it seems as if not a week goes by without a new report suggesting a supplement can reduce your cancer risk.

Take the medical view on the benefits or danger of the sun, for example. We all know exposure to the sun’s ultraviolet rays causes skin cancer. But just recently, the NY Times, BBC and others reported that your cancer prevention supplement routine should include high doses of Vitamin D (200-600 units per day). The skin makes vitmain D when exposed to the sun’s ultraviolet rays. (See recent study concluding that ). A few months ago Reuters and MSNBC supported this view when they reported that ovarian cancer rates are lower in sunny areas. And skin cancer risks are reduced if you drink green tea — and perhaps coffee. And if you drink coffee, you just might lower your risk of developing liver cancer. We’re confused already!

Only you, with the advice of your physician or health expert, can decide what cancer prevention supplement routine is appropriate for you and your family. This Cancer Prevention Supplement Guide is intended as a starting point to help research and ask the right questions about the cancer prevention supplement routine that makes sense for you given the weight of evidence and, of course, the risks and costs.

Several supplements (including or extracted from herbs, vitamins and super foods) have been shown in clinical trials to be associated with reduction in the risk of cancer. Although this is not a definitive list of cancer fighting supplements, it provides information and support on what we’ve found to be the most promising cancer prevention supplement recommendations and can provide a starting place for your to develop your own cancer prevention supplement routine.

Vitamin D

Vitamin D helps maintain blood levels of calcium, by keeping calcium in the body and sparing the calcium stored in your bones.

* Vitamin D and Colorectal Cancer: A higher intake of vitamin D is associated with a reduced incidence of colorectal cancer. Studies have showed that higher rates of colon cancer occur in the northern parts of the United States (where there is less sunlight) than in the southwest, Hawaii, and Florida. Researchers have advanced the theory that vitamin D, which the body can make in the skin after sun exposure, reduces colorectal cancer risk. Of course, sun exposure also brings skin cancer risk. See this article on natural sunscreens and protect yourself naturally without toxic substances.
* Vitamin D and breast cancer: insights from animal models. Vitamin D has also been associated with reduction in breast cancer. See the latest report: Vitamin D and calcium supplementation reduces cancer risk: results of a randomized trial abstracted in the American Journal of Nutritional Medicine. ol. 85, No. 6, 1586-1591, June 2007.

Vitamin E

Vitamin E is an antioxidant, which combats free radicals. Some experts believe that Vitamin E works better when combined in synergy with other antioxidants such as Selenium, Vitamin C, Vitamin A, and Beta-Carotene or mixed carotenoids. Vitamin E may inhibit a variety of cancers including esophageal, stomach, lung, and prostate.
CoQ10

Coenzyme Q10 (CoQ10) is used by the body to transform food into adenosine triphosphate (ATP), the energy on which the body runs. CoQ10 is found primarily in fish and meat, but the amounts in food are far less than what can be obtained from supplements. Some research suggests that a fat-soluble form of CoQ10 is absorbed better than CoQ10 in granular (powder) form. Adult levels of supplementation are usually 30–90 mg per day, although people with specific health conditions may supplement with higher levels (with the involvement of a physician). Animal Studies reported by the National Cancer Institute have found that coenzyme Q10 boosts the immune system and helps the body fight certain infections and types of cancer.

Vitamin C

Vitamin C is a water-soluble vitamin that has a number of biological functions. Good food sources of Vitamin C include broccoli, red peppers, currants, Brussels sprouts, parsley, potatoes, citrus fuit, and strawberries. Vitamin C has been shown by several studies to reduce the risk of several cancers including colon cancer and breast cancer (Br J Cancer. 1992 Oct;66(4):673) and bladder cancer. In addition to natural and supplement form, scientists have found that high doses of Vitamin C injected in the blood stream fight cancer.

Vitamin B Complexes

Vitamin B6 helps synthesize and maintain DNA. Vitamin B12 and folate work together to protect our DNA. Researchers from Brigham and Women’s Hospital (BWH) found that the vitamin may actually help reduce colorectal cancer risk. Folate, Vitamin B6 and Vitamin B12 intake have been linked to a reduced risk of breast cancer. A Vitamin B12 (folate) deficiency has been linked to an elevated rate of DNA damage, which is an important risk factor for cancer. Radioactive B12 has even been used by the Mayo Clinic to help locate cancer.

Antioxidants

According to Dr. Richard Cutler, former Director of the National Institute of Aging, “the amount of antioxidants in your body is directly proportional to how long you will live.” (See Benefits of Antioxidants). Antioxidants occur naturally in a variety of foods or in the form of supplements, and they include a family of naturally formed components like vitamin A, beta-carotene, lycopene, vitamin E, and more. They are believed to protect cells from free radicals, harmful oxygen molecules thought to damage cells that result in cancer. Also check out the National Cancer Insititute study on antioxidants and lung cancer.
Green Tea

The polyphenols in green tea have also been associated with reduced risk of several types of cancer in humans. Several animal and test tube studies have demonstrated an anticancer effect of polyphenols from green tea. In one of these studies, a polyphenol called catechin from green tea effectively inhibited metastasis (uncontrolled spread) of melanoma (skin cancer) cells.

Cancer Prevention Supplement Guide: Foods

(supplements for many of these foods are available)
By eating a rainbow of food colors or by emphasizing certain foods listed below, you can incorporate a variety of protective phytochemicals into your diet. These foods limit the free radical initiation and DNA damage caused by these carcinogens and therefore appear to lower the incidence of various types of cancer. They include:

* Beans
* Berries
* Cruciferous Vegetables
* Dark Green Leafy Vegetables
* Flaxseed
* Garlic
* Grapes and Grape Juice
* Green Tea
* Soy
* Tomatoes
* Whole Grains

DRINK LEMON JUICE: It’s really effective.. I recommend starting the day with one glass of hot water and lemon juice from 1 lemon. I’ve been doing this for 2 weeks and my acne is almost gone. My tip is that you wait at least 30 min after finishing the hot lemon juice before eating breakfast, to give the lemon time to remove dirt and sh*t from your liver, etc.

Drink water, eat less fat and sugar, eat more fruits and vegetables, avoid alcohol consumption and exciting food. And the law of life, adequate sleep, good mood, should develop good health habits, good personal hygiene, it is necessary to frequently wash with warm water to keep pores open.

What your face 2-3 times a day depending on your skin type. Make sure that you do not over dry your face. Washing your face a lot will dry it out, which will in turn cause your skin to produce more sebum, which will make your face more oily and cause it to get worse. Drink orange juice before you wash your face. It opens up the pores so it’s easier to get the oil out and other stuff. Washing your face does help a lot to fight acne and blackheads. Soap does not though. It dries out your skin. The only soap that works is soap made especially for your face. That won’t dry your skin out.

Your skin has essential oils and nutrients in it which protect it from harmful sun, chemicals and other elements. Washing all the protection away leaves your most delicate skin open for attack. Drying your face out by over-washing also leads to breakouts because there is no oil in your pores protecting them from harm. You can (and likely will) suffer sun damage and possibly skin cancers to the face if you wash away all the protective barriers.

Dermatologist suggest not to wash your face more than 2 times a day.

Scientists have found two new genetic variations that appear to increase the risk of the most common skin cancer among people of European descent.

The variations play no role in skin color but people with both of them are nearly three times more likely to develop basal cell carcinoma compared with people without the changes, researchers from Iceland’s Decode Genetics said on Sunday.

Darker skin is traditionally regarded as an important protection against skin cancer.

“Here we have two variants that have no impact on pigmentation and only affect the risk of basal cell carcinoma,” Kari Stefansson, Decode’s chief executive, who led the study, said in a telephone interview. “We don’t know why that is.”

Basal cell carcinoma is the most common form of cancer worldwide, and in the vast majority of cases are thought to be caused by exposure to ultraviolet rays of the sun, according to the American Academy of Dermatology.

Most cases are easy to treat when detected early, but in rare instances the cancer is resistant to treatment, causing damage to skin and sometimes invading bone and cartilage.

The researchers at Decode, a biotech company hunting for new drugs using Iceland’s unique gene pool dating back to the Vikings, analyzed genes of more than 30,000 people to identify the impact of the genetic variations located on chromosome 1.

These variations differed from past genetic changes linked to basal cell carcinoma in that unlike the others they were not associated with fair skin or pigmentation.

The study published in Nature Genetics also found that the risk of developing basal cell carcinoma was 12 times higher for people with these new variations along with the three other genetic changes already linked to the cancer.

“Exposure to the sun has no direct impact on the genes, which add to the total risk of basal cell carcinoma,” Stefansson said.
