An unusual type of heart attack

Sometimes, people have heart attacks that occur in the absence of a blocked heart artery. These unusual events can result from a number of causes, including a spasm or tear in one of the heart’s arteries or inflammation of the heart. (Locked) More »

Don’t wait until you turn 50 to screen for colon cancer

The American Cancer Society has updated its colon cancer screening guideline, recommending that screenings begin at age 45 instead of 50. The change was made in hopes of countering the growing number of colon cancer cases in younger Americans. The guideline recommends that people choose from a variety of different screening methods to find one that best suits their needs and risk profile. (Locked) More »

Aldosterone overload: An overlooked cause of high blood pressure?

An imbalance of the hormone aldosterone, which helps the body manage water and sodium, may be responsible for about one in 15 cases of high blood pressure. A benign tumor on one of the adrenal glands (which produce several hormones, including aldosterone) is the most common cause of excess aldosterone. This condition, called aldosteronism, may also contribute to coronary microvascular disease, in which the walls of the small arteries in the heart are damaged. (Locked) More »

Radiation from heart imaging: What you need to know

Some tests to diagnose heart disease involve small amounts of radiation, and these tests are being used with increasing frequency. Examples include coronary artery calcium scans, computed tomography angiography, and nuclear stress tests. But the theoretical increased risk of cancer from these tests is minimal, especially considering that radiation-induced cancers don’t occur for decades. (Locked) More »

Save your skin from cancer

Cases of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) skin cancers have more than doubled over the past decade, especially among men. However, BCC and SCC are rarely deadly and are easy to treat if they are caught early. It is also easy to lower your risk by following standard sun protection practices, including using proper sunscreen, avoiding the sun during peak exposure times, and wearing sun protection clothing and hats.

Should I get a bone density test?

Bone density tests are not routinely recommended for older men as there is no strong evidence they can benefit from osteoporosis-preventing medications. Lifestyle changes involving smoking, exercise, and alcohol intake can have the biggest impact on bone health. More »
