Skin cancer is the most common cancer in the United States. Here are some facts:

    • Over 3 million Americans are treated for skin cancer every year.
    • One in five Americans will develop skin cancer during their lifetime. 
    • Skin cancer is preventable and easy to detect.  
    • When caught early, this cancer is usually curable. 
    • Some types of skin cancer can be fatal.  

    Skin cancer is caused by sunlight damage to the skin. The only way to prevent it is to stay out of the sun, or block the sun’s rays.

    People with fair skin are more vulnerable to skin cancer. Those with dark complexions have some natural protection since their skin filters out some of the sun’s rays. Nonetheless, people of color can still get skin cancer. 

    The sun’s ultraviolet rays can damage the DNA of skin cells. These cells may grow abnormally and eventually become cancerous. This transformation may evolve slowly over many years or may occur earlier in life, particularly if sunlight exposure has been intense.  

    Sunlight can also lead to another problem premature wrinkling of the skin. Sun worshippers believe that a tan is healthy. In reality, a suntan is a sign of the skin injury. If it

As a lung specialist, I am often asked whether the body can recover from many years of smoking. Based on decades of research, the answer is a resounding “Yes” … but only if you quit smoking — completely.

What Are The Risks of Smoking?

Cigarette smoking kills over 480,000 Americans each year — more than the combined deaths from alcohol, illegal drug use, homicide, suicide, car accidents, and AIDS combined.

Cancer – Before cigarette smoking became widespread in the twentieth century, lung cancer was a rare disease. However, as smoking became popular, lung cancer rose to become a leading cause of death. Scientific research demonstrated that the toxic chemicals in cigarette smoke are carcinogenic. Smoking is also associated with cancers of the throat and digestive tract.

Heart and Vascular Disease – There is a strong association between smoking and the development of atherosclerosis, the “hardening of the arteries” that causes heart attacks, strokes and aneurysms. These conditions are among the major

For more than 30 years, October has been National Breast Cancer Awareness Month in the U.S. Breast cancer is the second most common cancer among women, second only to skin cancer. With more than 240,000 women diagnosed each year, awareness can save lives through early detection and lowering risk.

The main risk factors of breast cancer include being a woman and being older, which means almost any woman can be diagnosed with no family history or other known risk factors. The Centers for Disease Control and Prevention (CDC) recommends healthy living habits such as maintaining a healthy weight, regular exercise, getting plenty of regular nighttime sleep, avoiding carcinogens, and encourages women to breastfeed their children. These steps may help to reduce one’s risk to breast cancer.

The US Preventive Service Task Force recommends that women between the ages of 50 to 74 should have a breast cancer screening called a mammogram every two years. Women in their 40s should begin consulting with a doctor about when

We are now in June and summer is about to sweep across much of the United States. Over the next few months, it will be important to protect ourselves from the health risks posed by the sun and heat. Regardless of skin color, exposure to the sun carries many dangers to one’s skin—from freckles and wrinkles often associated with aging, to sunburns, benign tumors or cancerous skin lesions. Prolonged heat exposure can also have many negative impacts on one’s health ranging from a rash, exhaustion, fainting, or even death.

Although everyone should take precautions to protect their skin, the Food and Drug Administration (FDA) encourages those with pale skin; blond, red, or light brown hair; or who has a personal or family history of skin cancer to be especially careful while in the sun. The sun’s ultraviolet (UV) rays can damage one’s skin in as little as 15 minutes, and the best tool in combatting that skin damage is sunscreen. The American Academy of Dermatology suggests applying SPF 30 (at least) liberally 15 minutes before going outside, and to reapply at least every two hours to remain protected.
