Your doctor may one day be able to use a simple blood test to find out if you have cancer. Researchers from Johns Hopkins University reported in the January 19 issue of Science that they have developed a blood test that can spot early signs of cancer.

The researchers screened blood for DNA and proteins related to eight different types of cancer. They were able to identify early cancers from more than 1,000 patients with different types of cancer that had not yet spread. Over all, the test found 33% to 98% of cancers, depending on tumor type.

Combining multiple forms of radiation therapy with hormone treatments lengthens survival in men with aggressive prostate cancer.

Men whose PSA levels continue rising even after surgery or radiation therapy may have a new treatment option with the approval of the drug apalutamide.

Liquid biopsies may offer a less invasive alternative than a traditional biopsy.

A tissue biopsy is the standard test for identifying cancer. Your medical team will use needles or other devices to capture pieces of actual tumor to see if it's malignant or benign. But another approach, called a liquid biopsy, is less invasive and may provide a diagnosis when a biopsy doesn't.

This test uses a person's blood to look for signs of cells or mutated DNA that a tumor has shed into the bloodstream. "By sampling DNA or circulating tumor cells in the blood, we can predict and monitor responses to cancer treatments without subjecting patients to invasive biopsy procedures — and perhaps detect cancer early, before it has had a chance to spread," says Dr. David Miyamoto, assistant professor of radiation oncology at Harvard Medical School.

March is National Colorectal Cancer Awareness month. Have you been screened? Colon cancer is the second leading cause of cancer deaths in the United States, but is also highly preventable through recommended screenings. These screenings enable doctors to spot precancerous lesions that can lead to colon cancer and remove them before they become a problem. Screenings can also find cancers early, when they are most treatable. All people ages 50 to 75 should get recommended colon cancer screenings. Some people should start getting screened earlier if they have certain risk factors for colon cancer, including a family history, a personal history of inflammatory bowel disease (such as Crohn's disease or ulcerative colitis), or a genetic condition that makes colon cancer more likely (such as familial adenomatous polyposis).

There are several tests used for colon cancer screening, including colonoscopy, which uses a device to examine the full length of the colon and rectum; stool tests; flexible sigmoidoscopy, which uses a device to examine a portion of the colon; and CT colonography, a scanning technique that produces images of the colon that are examined by the doctor.

Here are some signs of an alcohol use disorder — and ways to find the help you need if you suspect you're drinking too much.

The thought of hangovers and binge drinking may conjure an image of a college-age student or a 20-something out on the town. But increasingly, those terms apply to people who probably look a lot like you.

Alcohol use problems often start innocently enough in older women. A problem may begin with a drink at night to combat insomnia, says Dr. Olivera Bogunovic, assistant professor of psychiatry at Harvard Medical School. But then one drink turns into two, and a 9 p.m. cocktail turns into all-day drinking, she says.

Men with prostate cancer that has spread outside the gland now have several newer drug options available for treatment, and research has found that taking any of them is likely to improve survival duration.
