Cancer is the catchall term applied to diseases caused by the uncontrolled growth of abnormal cells. Cancer isn't one disease. It is many different diseases, more than 100 and counting.

Each kind of cancer is usually named for the cell type in which it begins — cancer that starts in a lung is called lung cancer; cancer that starts in pigment cells in the skin, which are known as melanocytes, is called melanoma.

When detected and treated early, cancer can often be stopped. That said, cancer is a leading cause of death and disability around the world.

Can we detect cancer earlier?

Harvard researchers have developed a new way to detect signs of cancer in the blood. They’ve invented a hand-held device that quickly determines the number of microvesicles in a drop of blood. Microvesicles shed by tumors have been ignored by the medical community for decades because it was not known until recently that they contain imprints of originating cells and also DNA and other molecules. The detection device may help find a person’s cancer before it has spread too far to be cured. It may also help determine how well a cancer treatment is working. More »

Latest Mohs skin cancer surgery guidelines

Dermatologists now have official guidelines for Mohs surgery, a procedure that removes skin cancer while minimizing damage to surrounding healthy tissue. The new Appropriate Use Criteria (AUC) for Mohs surgery, approved by a number of dermatologic associations, will help doctors better select patients for the procedure. Mohs surgery is warranted in 200 out of 270 scenarios named in the AUC. Smaller, more superficial skin growths may not be right for Mohs surgery. (Locked) More »

Multivitamin use may reduce cancer risk

Multivitamins may reduce the risk of cancer in men by 8%. The benefits of multivitamin supplements may mirror those found in vitamin-rich fruits and vegetables, which also have been associated with lower cancer rates in previous studies. (Locked) More »

Can aspirin help fight cancer?

Aspirin is one of the most widely used medications in the world. In addition to its applications for pain relief and prevention of heart attacks and strokes, research is now finding aspirin may be valuable for cancer prevention. Studies have highlighted aspirin’s ability to prevent several types of cancer, including esophageal, pancreatic, lung, colorectal, prostate, skin, and breast cancers. Although it’s too early to recommend aspirin specifically for cancer prevention, this may provide an additional benefit for people who are already on daily aspirin therapy.   (Locked) More »

Do-it-yourself skin cancer checks

Skin cancer checks need to be a year-round maintenance effort. About 50% of melanomas are identified by patients, and even more are discovered if the skin is examined with the help of a partner. Using a computer-based tutorial to learn how to check for skin cancers can help you catch the problems early. Pay particular attention to spots that have grown or display a variety of hues, such as tan, black, brown, pearly, or translucent; moles or pigmented spots that have changed in color, mass, or contour; or sores that continually crust, bleed, itch, hurt, or don’t heal.   (Locked) More »

No need for routine ovarian cancer screening

The U.S. Preventive Services Task Force (USPSTF) has reaffirmed its 2004 recommendation that women at low risk not be routinely screened for ovarian cancer, because routine screening does not reduce ovarian cancer deaths. (Locked) More »
