Treatment decisions are complicated for men with low-risk prostate cancer that grows slowly. These cancers may never become deadly during a man’s expected lifespan. And there is no conclusive evidence showing that treatment in these cases extends survival. So cancer specialists have been leaning toward monitoring low-risk prostate cancer carefully and starting treatment only when it begins to spread. This approach was once used only in academic cancer centers, but new research suggests that this strategy is becoming more common in urology practices throughout the United States and other countries as well.

Can a healthy diet help men with low-risk prostate cancer live longer? The authors of a new study say “yes.” A long-running Physicians’ Health Study, suggests that a diet that is good for the heart, brain, and other parts of the body may also help keep low-risk prostate cancer at bay. On the flip side, a diet rich in red meat and high-fat dairy foods appears to be hazardous for men with this kind of cancer. It isn’t clear why a diet that protects against heart disease would also protect against death from prostate cancer. Dr. Chavarro speculates that it’s because high-fat foods are easily broken down and absorbed by the digestive system, and so they might provide quick energy sources for growing tumors. Nevertheless, the results suggest that by eating healthily, men with prostate cancer can take a proactive step towards living a long life.

Proton-pump inhibitors offer welcome relief for people with chronic heartburn. Here's what you need to know to use them wisely.

Heartburn didn't get its name by accident. Although the problem stems from excess stomach acid rather than heart-related issues, it provokes searing pain focused directly behind the breastbone. Of the over eight million emergency room visits for chest pain each year, severe heartburn, also known as gastroesophageal reflux disease (GERD), accounts for over half the cases in which actual heart problems are ruled out.

There's no guarantee you can prevent cancer, but you can reduce the risk of developing it by making lifestyle changes.

If a growth or mole looks like a melanoma, the doctor will take a biopsy to confirm the diagnosis. This entails removing either a sample of tissue or else the entire growth and some surrounding skin, and examining the tissue under a microscope to determine whether it's cancer. Depending on how deep a melanoma is, additional tissue may have to be removed. In some cases, lymph nodes may be removed, too. A procedure called sentinel node biopsy can show whether the lymph node nearest the tumor contains any cancer cells. If it does, surgery to remove additional nodes right away can improve survival.

In addition to surgery, treatments for melanoma include immunotherapy (which strengthens the immune system against the cancer), chemotherapy, and radiation therapy. Newer, so-called targeted treatments include drugs that target specific genetic changes seem in people with certain forms of melanoma. For example, about half of melanomas have genetic changes (mutations) in a gene called BRAF, which signals melanoma cells to grow and divide quickly. Drugs that inhibit BRAF, such as vemurafenib (Zelboraf ) and dabrafenib (Tafinlar), and related proteins are now available.

Active and retired servicemen with prostate cancer can get access to clinical trials, experimental therapies, and state-of-the-art care through the Department of Defense’s Center for Prostate Disease Research (CPDR).

Q. I heard that there is a new stool test for colon cancer screening. Can this test replace colonoscopy for me? I am 68 years old with no history of colon problems, and my last colonoscopy was normal.

A. Among screening tests for hidden colorectal cancer, colonoscopy remains the "gold standard" because it's the most effective technique for detecting colon cancers and simultaneously provides an opportunity to remove any precancerous growths (polyps). The new DNA-based stool test (Cologuard) is less invasive and inconvenient than colonoscopy and finds more cancers and polyps than older stool tests, but it does not entirely eliminate the need for colonoscopies.

An approach called active surveillance allows some men with low-risk cancer to delay the decision to treat.

Q. I am scheduled to have my prostate removed and am concerned about the risk of erectile dysfunction (ED) after the surgery. I've heard that taking an ED drug daily during my recovery could help. Do you recommend this?

A. About half of men lose some erectile function after radical prostatectomy, which removes the entire prostate gland. ED drugs help men to have erections after surgery, but so far research has not shown that taking it daily produces better results than taking the medication as-needed—when you anticipate sexual activity.

Maintaining a healthy weight is the best way to rein in gastroesophageal reflux disease (GERD), or chronic heartburn, according to a study in The American Journal of Gastroenterology. Researchers found that GERD symptoms increased for every incremental rise in body mass index (BMI), which measures the ratio of weight to height.

In GERD, the acidic contents of the stomach back up into the lower esophagus, causing burning pain. The most effective treatment for GERD is taking an acid-reducing proton-pump inhibitor medication, such as omeprazole (Prilosec). People who are overweight are much more likely to develop GERD.
