SEEING IS BELIEVING

Ultraviolet (UV) rays are an invisible kind of radiation that come from the sun, tanning beds, and sunlamps. UV rays can penetrate and change skin cells.
The three types of UV rays are ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC)—

• UVA is the most common kind of sunlight at the earth’s surface, and reaches beyond the top layer of human skin. Scientists believe that UVA rays can damage connective tissue and increase a person’s risk of skin cancer.

• Most UVB rays are absorbed by the ozone layer, so they are less common at the earth’s surface than UVA rays. UVB rays don’t reach as far into the skin as UVA rays, but they can still be damaging.

• UVC rays are very dangerous, but they are absorbed by the ozone layer and do not reach the ground.

More than 670,000 men are diagnosed with prostate cancer globally every year, making it the second-most common cancer in men, after lung cancer. In the U.S., about 600,000 men are being treated with endocrine therapies for prostate cancer
What patients should do is talk about this with their doctor?
Experts said the findings could make doctors think twice before prescribing the standard hormone treatment to men with prostate cancer, particularly if they are at risk of heart disease. The research was announced Tuesday at a joint meeting of the European Cancer Organisation and the European Society for Medical Oncology in Berlin.
Prostate cancer patients had a 28 percent higher relative chance of having a fatal heart attack and a 21 percent increased chance of dying from heart disease. Still, these risks were low in absolute terms: researchers estimated the hormone therapies would cause an extra 10 heart problems — like chest pain or a heart attack — a year for every 1,000 prostate cancer patients.
Previous studies have found hormone therapy given to prostate cancer patients with a history of heart disease increases their chances of dying.

If you are aged 50 or older, or think you may be at higher than average risk for colorectal cancer, speak with your doctor about getting screened.
Colorectal cancer affects both men and women of all racial and ethnic groups, and is most often found in people aged 50 years or older. For men, colorectal cancer is the third most common cancer. For women, colorectal cancer is the second most common cancer among Asian/Pacific Islander and Hispanic women, and the third most common cancer among white, black, and American Indian/Alaska Native women.
