Dermatologist #1 Skin Care Rule – Wear Sunscreen!

Melanoma Web MD ChatIt’s almost summer time, and many of us are already spending more time outside enjoying the warm weather. Most of us don’t consider the consequences of increased sun exposure on our skin, even indirect exposure. Skin cancer is the most common type of cancer in the United States, with about one million new cases every year. The three common forms of skin cancer are distinguished by the types of cells affected: melanoma, basal cell and squamous cell. While melanoma is less common than basal and squamous cell cancers, it is the most dangerous. If caught early, melanoma can be treated; however, if left untreated, melanoma can spread to other parts of the body.

What is Melanoma?

Melanoma is a cancer of melanocytes, which are cells whose primary function is to make pigment. These cells are located in the layers of epidermis, or the outer layer of skin. Melanocytes are also responsible for making birthmarks and freckles; however, in those cases, the cells are not cancerous. Melanomas can form on any part of the skin but are most commonly found on the chest and back in men, and the legs in women. Melanomas can also develop on the neck and face, and they sometimes occur in the eye and in mucosal surfaces, such as the mouth and bowel.

Why do dermatologists recommend applying sunscreen daily?

Skin cancer is most commonly a result of excessive exposure to the sun’s ultraviolet (UV) rays. The sun contains two types of these rays: UVB, which are responsible for sunburns, and UVA, which cause cell aging and long-term skin damage. Both rays cause damage to skin cells’ DNA, resulting in abnormal cell growth. Here are some tips to protect your skin from the sun’s harsh rays and prevent skin cancer:

  • Use a broad spectrum SPF of a level 15 or higher, which is a type of sunscreen that protects the skin from both UVA and UVB rays.
  • Avoid outdoor activity between 10 a.m. and 4 p.m., when the sun’s rays are most intense.• Wear protective clothing as well as a hat and sunglasses to protect more sensitive parts of the body.
  • Remember, the UV rays can go through light clothing, windshields, windows, and clouds.
  • While shade offers some protection, the sun’s UV rays can still penetrate through clouds and trees and have harmful effects.

Check yourself!

Remember, skin cancer is generally treatable if detected early. If you haven’t done so, give your body a quick scan, and repeat this practice at least once a month. Get to know the pattern of moles, spots, freckles, and other marks on your skin. If you notice any new moles or changes in shape or color to existing ones, please contact your healthcare provider.

Top 8 FAQs: Nutrition’s Role in Fighting Cancer

Nutrition to Fight CancerWe had a great discussion on April 11th about nutrition with Tiffany Barrett, MS, RD, CSO, LD. She answered some great questions about the importance of maintaining a healthy diet to fight off cancer and enhance treatment. If you missed out on our live chat, the transcript is available here. Also, see below for highlights from the discussion.

Q: What are some good foods to eat during cancer treatment or to prevent cancer from reoccurring?

A: When it comes to reducing the likelihood of recurrence, reducing saturated fat intake is very important. This includes eliminating animal fat, butter, lard, etc. It is important to increase your intake of plant foods and grains while incorporating a variety of produce into your diet (i.e. leafy greens, berries, etc.).

Q: Is there a role that sugar plays in cancer?

A: First, it’s important to note there’s a difference between natural and refined/processed sugars. Unlike naturally occurring sugars found in fruit and dairy, processed sugars are significantly correlated with elevated bad cholesterol and triglycerides (fat in blood) and low good cholesterol. Eating too much added sugars can also result in excess body weight, which can increase the risk of cancer. It is best to limit your intake of sugar and sugary foods to protect your health, limit excess calories and make room for nutrient-dense foods that contain naturally occurring sugars (fruit, low-fat dairy).

Q: What is a good substitute for sugar?

A: There always are options like stevia, honey and agave nectar, but all of these are a bit sweeter than real sugar, so using less of them is advised. It’s important to understand that using moderation in any sort of sweetener is key. If you are having sugar cravings, focus on natural sources of sugar.

Q: Is there a connection between soy products and cancer?

A: There is evidence that soy intake (whole soy foods, rather than processed) prior to cancer diagnosis can have preventive effects. This has been found specifically with breast, prostate, and colon cancers. Whole soy food includes tofu, soy milk, edamame, and soy beans, whereas processed soy is found in things like soy hot dogs, soy burgers, soy powders, etc.

Q: Is food the best source for receiving nutrients? What about supplements and vitamins?

A: Our body best digests and absorbs nutrients through food consumption. There’s actually no hard evidence to demonstrate benefit from a standard multivitamin or other supplement use. Consuming nutrients through food allows for a wider variety of vitamins.

Q: Are meal replacement drinks a feasible option to getting proper nutrition during cancer treatment?

A: Meal replacement drinks certainly can be and often are helpful in combating or overcoming some of the side effects of treatment, such as loss of appetite. There are a wide variety of meal replacement drinks that provide a full balance of necessary nutrition, and also ways that people can make their own protein and meal replacement drinks at home to suit their taste.

Q: Is there any connection between physical activity and cancer prevention?

A: Absolutely. Regular, moderate physical activity: 4-5 times per week for 30-45 minutes each time, has been shown to have preventive effects.

Q: How important is it to start early with good nutrition to receive preventive benefits?

A: Starting young as far as introducing good eating habits to children is imperative. It’s also important to educate at a young age about the importance of maintaining a healthy weight. Good nutrition and maintaining a healthy weight are important in reducing not only your risk for cancer, but for a whole host of other conditions that are largely preventable.

An Intro to Colorectal Cancer Part I: Risk Factors, Symptoms & Diagnosis

Colorectal Cancer Awareness MonthMarch is colorectal cancer month, and an article in the New York Times highlights the important role colonoscopies have played in reducing deaths from colorectal cancer. The study included patients tracked over 20 years after receiving a colonoscopy, which lead to the detection and removal of precancerous polyps, known as adenomatous polyps. Findings from the study show that the combination of a colonoscopy and polyp(s) removal lowered the colorectal death rate by 53 percent. While not all polyps turn into cancer, evidence shows that early detection and intervention are keys to survival. In the spirit of helping raise awareness around Colon Cancer and the importance of colonoscopies as a diagnostic and preventive tool, below you’ll find some helpful resources and important information about colorectal cancer.

Colorectal Cancer Statistics

According to the American Cancer Society, “excluding skin cancers, colorectal cancer is the third most common cancer diagnosed in both men and women in the United States.” That means in 2012, estimates for the number of colorectal cancer cases that will be diagnosed in the United States are:

  • 103,170 new cases of colon cancer
  • 40,290 new cases of rectal cancer

But, if detected early enough, colorectal cancer is curable. So, how is colorectal cancer detected?

Colorectal Cancer Diagnosis

According to the Winship Cancer Institute of Emory University, “colorectal cancer usually starts in the innermost layer of the lining and slowly progresses through the other layers.”  There are several ways of diagnosing colorectal cancer, but the most popular method is a colonoscopy. A colonoscopy is a special type of cancer screening because it allows doctors to screen and intervene at the same time.

During a colonoscopy, the doctor will use a colonoscope, which is a flexible, lighted tube with a small video camera on the end. They use this instrument to look at the entire length of the colon and rectum. If the doctor finds abnormalities such as polyps or growths, he or she can remove them right away while patients are under sedation. Special instruments can be passed through the colonoscope to remove the suspicious looking areas before they have the chance to turn into cancer.

Colon Cancer Web Chat

According to Roberd Bostick, MD, MPH and a professor in the Department of Epidemiology at Emory University’s Rollins School of Public Health, “most of the time, a colonoscopy is the most effective means for diagnosing [colorectal cancer].Certainly, if a person were to have symptoms that would be suggestive of colon cancer, then those symptoms might precipitate them wanting to have a diagnostic test, like a colonoscopy.”

For a full list of symptoms and risk factors of colorectal cancer, please see below. Watch the full video discussion with Roberd Bostick, MD, MPH. Also, bring your additional questions to Dr. Bassel El-Reyes and Dr. Roberd Bostick’s colon cancer chat on March 20th (UPDATE – CHAT TRANSCRIPT).

Colorectal Cancer Symptoms

If you are experiencing any of these symptoms, contact your doctor to be properly diagnosed and treated. It’s important to note that these symptoms may not necessarily be a result of colorectal cancer. Other health problems can produce similar symptoms, which is why it is important to contact your physician if you are experiencing any of the symptoms listed below:

  • Change in bowel habits:
    • Diarrhea or constipation
    • Feeling that your bowel does not empty completely
    • Finding blood (either bright red or very dark) in your stool
    • Finding your stools are narrower than usual
  • Frequent gas pains or cramps, or feeling full or bloated
  • Loss of weight for no apparent reason
  • Feeling very tired all the time
  • Nausea or vomiting

Colorectal Cancer Risk Factors

The main risk factors for colorectal cancer are uncontrollable. They are heredity, family history and personal medical history. Other risk factors include:

  • Presence of an inflammatory bowel disease (i.e. Crohn’s disease, ulcerative colitis, etc.)
  • Diabetes
  • Other controllable factors
    • Obesity
    • Red meat consumption
    • Processed meat consumption
    • Smoking
    • Alcohol consumption

Remember, early detection is the key to providing the best chance for a cure. It is important to contact your physician if you are experiencing symptoms or are at risk for colorectal cancer.  If your physician feels it’s appropriate, a screening test, such as a colonoscopy, will most likely be recommended to rule out the possibility of cancer.

With all this information, what can you do to stay healthy? Take action and make sure you are getting regularly screened! While a colonoscopy is bound to not be the most pleasant experience, it could potentially save your life by detecting colorectal cancer early when the disease is easier to cure.  If you are interested in learning more about colorectal cancer, make sure to check out the chat transcript the colorectal cancer chat.

How to Support Your Loved Ones in their Efforts to Quit Smoking

If you want a loved one to stop smoking and you feel tempted to nag him or her, you may want to try to curb your impulse. You might be doing more harm than good, a Winship Cancer Institute expert says. Reinforce positively and try not to nag, advises Carla Berg, Ph.D., a member of the Cancer Prevention and Control department of Winship and also a professor in the Rollins School of Public Health.

Help Your Loved Ones Quit SmokingWith Heart Month upon us and roughly 17-18%  of adults in the United States continuing to smoke, this is important. Smoking is not only is the major cause of lung cancer, the nation’s number one cancer killer, but it’s also responsible for as many as 30% of all coronary heart disease deaths in the United States each year. Smoking is a major risk factor for more than two dozen other cancers, including head and neck cancer, bladder cancer and stomach cancer.

Berg says an important component can be providing support to someone who is trying to quit. The initiation, maintenance and cessation of smoking is strongly influenced by other family members, Berg says. Smokers are more likely to marry smokers, to smoke the same number of cigarettes as their spouse, and to quit at the same time. Smokers who are married to nonsmokers or ex-smokers are more likely to quit and remain abstinent. In addition, married smokers have higher quit rates than those who are divorced, widowed or have never married. Research shows that support from the spouse and from other family members and friends is highly predictive of successful smoking cessation. In particular, supportive behaviors involving cooperative behaviors, such as talking the smoker out of smoking the cigarette, and reinforcement, such as expressing pleasure at the smoker’s efforts to quit, predict successful quitting. Negative behaviors, such as nagging the smoker and complaining about smoking, are predictive of relapse. In fact, supportive behaviors have been associated with initial smoking cessation, while negative or critical behaviors have been associated with earlier relapse.

In addition, encouraging the establishment of smoke-free homes reduces exposure to secondhand smoke among all people living with smokers. Because secondhand smoke exposure has been found to have detrimental effects on the cardiovascular health of people living with smokers, particularly children in homes where smoking occurs, promoting smoke-free homes is critical. Research also has shown that creating smoke-free homes also encourages attempts to quit smoking and reduced cigarette consumption among smokers.

Do:

  • Talk the smoker out of smoking the cigarette
  • Express pleasure at the smoker’s efforts to quit
  • Encourage smoke-free home policies
  • Support attempts to quit

Don’t:

  • Nag the smoker
  • Complain about smoking
  • Shun the smoker
  • Shame or guilt the smoker

Get the Real 4-1-1 on HPV

Cervical Cancer Awareness HPVWho could have imagined that a three-letter virus – HPV — could generate so much confusion and controversy?

Oh, wait, there is precedence for all the political posturing, fear and mis-information about HPV, the human papillomavirus, one of the most common sexually transmitted infections. We saw the same take place around HIV, a far more deadly virus and one that continues to wreak havoc and claims thousands of lives a year. And it took decades of advocacy, much of which is still ongoing, to bring attention to the need to stop HIV in its tracks, before it leads to AIDS. That same advocacy and public health campaigning is now underway to help consumers better understand HPV and what people can do about it, and how important it is for young people to receive vaccines that can protect them from infection with the virus.

Researchers have identified more than 40 types of HPV, a very common virus that the human body normally sheds on its own. Two types – HPV 16 and HPV 18 — are of special concern in the cancer community, though, because, undetected and untreated, they lead to most cases of cervical cancer. Now one of them, HPV16, is proving to be the cause of most new cases of throat cancers that develop at the base of the tongue and tonsils.

Routine pap tests and annual gynecological exams have lowered cervical cancer incidence in the United States, but cervical cancer is still one of the leading cancer killers of women worldwide. Thus, great research emphasis was placed on finding a vaccine to prevent infection with HPV 16 and 18 in the first place. Now there are two such HPV vaccines licensed by the FDA to prevent the spread of HPV and thus to prevent cervical cancer.

While screening with the Pap test has long proven an effective way to help prevent cervical cancer in developed countries, screening for HPV 16 infection for throat or other kinds of cancer would be fruitless. While 20 million Americans are estimated to be living with HPV 16 in their systems, 90% of those people will clear the virus on their own. A big concern with HPV 16 and throat cancer is that doctors do not yet understand why the virus becomes cancer in some.

Because the virus is so widespread yet causes cancer in a relatively small percentage of cases of infection, screening for it does not make sense, explains Dr. Shin, a leading head and neck cancer specialist at Winship Cancer Institute of Emory University. The most important unanswered question about HPV16 and throat cancer is why does it develop into cancer in some people but not in the majority of people.

“How does this virus get into a host cell and then go into carcinogenesis? This is what we would like to address,” explains Dr. Dong Moon Shin. Winship researchers such as Shin are aggressively looking for answers.

Much of the confusion and political hoopla about HPV have stemmed from misinformation about the vaccine, which is unfortunate. The vaccine is safe. It is effective. Because of the rising incidence of oropharyngeal cancer, it is now advised that both girls and boys also receive the vaccine, which is given in a series of three shots. To be effective, the shots must be given before a girl or boy becomes sexually active and is not administered to females after they hit age 26. Some of the concern about the vaccine is that parents don’t like the idea of giving children another round of vaccines, but the HPV vaccines have been approved by the FDA after rigorous clinical trials. They work.

HPV facts & stats:

  • More than 40 types of HPV have been identified by researchers.
  • More than 20 million adult Americans are believed to be living with the HPV 16 virus.
  • In 90 percent of cases, the body’s immune system clears HPV within two years.

Prognosis for cases of HPV16-caused throat cancer is good, so long as the patient is a non-smoker. Winship researchers and others are looking for ways to identify whether patients with HPV16-caused throat cancer need as much treatment as patients whose cancer is not caused by the virus.

Dr. Peter Rossi and Dr. Namita Khanna just hosted an online chat on the topic of HPV and cervical cancer. For their thoughts, check out the HPV / Cervical Cancer chat transcript.
