Long-term hormonal therapy, which blocks the effect of testosterone on prostate tumors, was once reserved for prostate cancer that has spread. But recent research has found that it had enormous benefits for men with earlier stages of prostate cancer, slashing their risks of metastasis and death from prostate cancer. However, some questions remain — for example, exactly how long to use “long-term hormonal therapy” is still up for debate.
The same BRCA mutations that increase a woman’s risk of breast and ovarian cancers can also increase a man’s risk of dying from prostate cancer. Recently, an ovarian cancer drug intended for BRCA-positive women has shown impressive results in BRCA-positive men with metastatic prostate cancer. This drug, and others like it, could provide another, much-needed treatment option for men with advanced prostate cancer.
There’s almost always something we can do to improve our health and well-being — even at the end of our lives. Palliative care is designed to improve the quality of life for people with life-threatening illnesses and their families by keeping a person comfortable and making sure his or her values and preferences guide the medical team’s actions. For this reason, good communication with your care team — and your loved ones — is essential, even before you or a loved one has developed a serious illness.
Last year, only months after announcing that he had an aggressive form of melanoma, former President Carter declared that he was cancer free — thanks at least in part to a recently approved immunotherapy drug. Immunotherapy is a type of targeted therapy that helps boost the body’s own immune response to cancer. It does so while sparing healthy cells, thus minimizing side effects.
Fewer men are being given PSA tests to screen for prostate cancer. As screening rates have fallen, so have the number of prostate cancer diagnoses. This probably also means that fewer men are receiving potentially unnecessary treatment, with its attendant negative side effects. At the same time, it isn’t yet clear whether that comes at the cost of more aggressive cancers being caught at an incurable stage. Better screening tests may make the difference in helping strike the right balance between limiting harm and preventing prostate cancer deaths.
When it comes to pain management, focusing only on reducing the intensity of pain may lead to treatments that do as much harm as good. Ideally, pain-management plans should be tailored to each patient and include a range of therapies that not only reduce pain but also help improve pain-related quality-of-life problems.
A new study confirms that active surveillance is a safe and reasonable alternative to immediate treatment for prostate cancer. In recently published study that followed 1,300 men, the prostate cancer survival rate after 10-15 years of active surveillance, was 99%. For some men, a strong discomfort with “living with cancer” may steer them away from postponing treatment in favor of careful monitoring.
Blood clots can be lifesavers when they form outside the bloodstream to stop bleeding from an injury. But they can wreak havoc when they form inside the bloodstream. A blood clot in a coronary artery can cause a heart attack. One in the brain can cause a stroke. Blood clots that form in a leg vein cause a problem known as venous thromboembolism, or VTE. If the clot stays in the leg, it can cause swelling or pain. If it breaks away and travels to the lungs, it can cause a potentially deadly pulmonary embolism. In about half of people who develop a VTE, doctors can identify what caused it. In the other half, VTE is something of a mystery. These are called “unprovoked” VTEs. Such unprovoked VTEs often spark a search for hidden cancer. But a study published in The New England Journal of Medicine suggests that these searches are usually fruitless — and costly.
Switching from a “Western” diet with lots of fat and meat to a fiber-rich diet for just two weeks makes conditions in the large intestine less favorable to the development of colon cancer. The opposite switch may promote the formation of cancer. That’s the conclusion from a small but elegant study done in urban Pittsburgh and rural KwaZulu-Natal, South Africa. In the study, 20 volunteers from each area switched diets. For two weeks, the Americans ate a traditional high-fiber African diet rich in fruits, vegetables, nuts, and beans, while the Africans ate a Western diet with more fat, protein, and meat. In just two weeks, significant changes occurred in the lining of the colon and in its chemical and bacterial make-up in both groups, but in different directions. Those following the African diet showed improvements in colon health likely to protect against colon cancer, while those following the Western diet showed changes that could lead to colon cancer.
Looking for ways to ward off colorectal cancer? According to a new study, a pescovegetarian diet — that’s a vegetarian diet that includes fish — was linked to a 43% reduction in the risk of developing colorectal cancer. The study, published in JAMA Internal Medicine, adds more support to the notion that something in red meat, or the way it is cooked, encourages the growth of colorectal cancer. It’s also possible that eating more plant foods provides extra beneficial nutrients such as folate, calcium, and fiber that may protect against colorectal cancer. Fish contain healthful omega-3 fats and vitamin D. Another good strategy for preventing harm from colorectal cancer, the second leading cause of cancer death in the United States? Have colonoscopies as needed.
