Smoking—cigarettes, cigars, pipes, marijuana, and even electronic cigarettes, or e-cigarettes—can have a harmful effect on your entire body, but especially on your respiratory system. This includes your airways, lungs, certain blood vessels, and the muscles that power your lungs. Cigarette smoking, for example, is responsible for nearly 90% of all lung cancer deaths and 80% of chronic obstructive pulmonary disease (COPD), which includes things like emphysema and chronic bronchitis. These can be life-threatening conditions that make it difficult to breathe. Smoking also exacerbates (worsens) other lung disorders, such as asthma, a condition in which the lungs swell and the airways narrow, making the flow of air in and out of the body difficult. Learn more about how smoking causes lung disease and how to recognize the signs of damage.

SDI Productions / Getty Images En español At some point, you might have lifted an arm or peered at your neck in the mirror and discovered a skin-colored growth that wasn't there before. What you found was most likely a skin tag, given that about half of us will have at least one of these harmless protuberances over the course of our lifetime. The older we get, the more of them seem to pop up. Skin tags, or what your dermatologist calls acrochordons, are usually harmless and nothing to worry about. Yet there are some situations in which you'll want to consult with your doctor, especially if you're wondering whether to remo...

The blood test used to detect prostate cancer may be more effective at preventing deaths — particularly among Black men — than previously thought, according to a study in NEJM Evidence. Why it matters: Prostate cancer has one of the most pronounced disparities by race of any cancer, and Black men have historically been underrepresented in trials despite having double the risk of dying from it, the authors write. Zoom in: Previous studies found prostate-specific antigen (PSA) screening prevented one death for every 23 men diagnosed, resulting in overdiagnoses and overtreatment. In this study, led by Weill Cornell Medicine, researchers took another look, using additional data and estimates for men of all races. They ultimately calculated one death was prevented for every 11 to 14 men of all races diagnosed using PSA screening. For Black men, screening prevented one death for every eight to 12 men diagnosed and one death for every five to nine men treated for prostate...

Skin cancer is the most common type of cancer in the United States. Research suggests that at least 1 in 5 Americans will develop skin cancer by 70 years old. The condition is also diagnosed in more than 9,500 people every day in the United States. Additionally, more than two people die of skin cancer each hour. Although people with lighter skin tones are at a higher risk of developing skin cancer, anyone can get it. Furthermore, people with darker skin tones are often diagnosed at a later stage, which increases their risk of dying from skin cancer. However, skin cancer is highly preventable. It can also be cured in 99 percent of cases, as long as it's treated early. In honor of Skin Cancer Awareness Month in May, this article will focus on the importance of protecting your skin and why it's essential to be proactive if you notice any unusual skin changes. Skin cancer involves the irregular growth of malignant (cancerous) skin cells. In general, skin cancer is classified as: Th...

When it comes to lung health, you're likely already familiar with the respiratory red flags that can point to a problem: wheezing, coughing, and shortness of breath, for instance. But fewer people realize that certain lung problems can present with non-respiratory symptoms—and these may even show up on your skin. Experts are now sharing four surprising skin symptoms that could alert you to one of several serious lung conditions, from lung cancer to pulmonary fibrosis. Read on to learn what to watch out for.

Cancer is the second leading cause of mortality in the United States [1]. Among all cancers, skin malignancy is the most common. Melanoma is the most aggressive and dangerous form of skin malignancy [1]. Cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitors were first approved by Food and Drug Administration (FDA) in 2011 for the treatment of melanoma [2]. Meanwhile, programmed cell death 1 (PD-1) inhibitors were approved in 2015 by FDA for melanoma [3]. Ipilimumab is an anti-CTLA-4 agent that promotes the function and growth of T-cells by strengthening the immune system. Nivolumab is a PD-1 inhibitor that promotes the tumor-killing effects of T-cells. Ipilimumab and nivolumab have emerged as successful treatments and have demonstrated an overall survival benefit in metastatic melanoma [4]. Since immunotherapies are becoming more common, immune-related adverse events are now coming into the limelight. The adverse effects are thought to be related to the development of auto-...
