Completing cancer therapy can feel like a graduation. You've done some hard work, it's paid off, and you may be ready to celebrate. But saying goodbye to treatment can arouse many of the emotions and uncertainties associated with beginning a new chapter in life.

Dr. Larissa Nekhlyudov is a general internist who works with cancer survivors at two Harvard affiliates, Brigham and Women's Hospital and Dana-Farber Cancer Institute. She acknowledges that cancer survivors have a lot to deal with. "Once you've had your final chemotherapy infusion or swallowed the last pill, you may find yourself facing a new set of challenges—monitoring yourself for signs of recurrence, getting recommended follow-up care, adjusting to the long-term effects of treatment, psychologically adapting to normal life, and working to stay in good health," Dr. Nekhlyudov says.

Beverages consumed at temperatures above 150° F may contribute to esophageal cancer.

Researchers believe that a non-invasive screening test that can identify genetic markers for high-grade prostate cancer in urine may eventually reduce the number of prostate biopsies needed. However, experts also caution that while the number of non-invasive tests for prostate cancer diagnosis is growing, these are still early days in their development.

Research has found that people with high levels of the oral bacteria Porphyromonas gingivalis had a 59% greater risk of developing pancreatic cancer. It is too early to say whether this specific bacterium directly contributes to the disease. However, one theory is that since inflammation is related to cancer, the bacteria could cause inflammation in the pancreas. Another possibility is the bacteria are simply a marker for cancer-causing inflammation. 

While e-cigarettes do not produce the tar or toxic gases found in cigarette smoke, this doesn’t make them a healthy option. The e-liquid found in e-cigarettes still contains highly addictive nicotine that also increases your risk of insulin resistance and type 2 diabetes. Nicotine also increases the risk of addiction to other drugs and may impair brain development. Rather than rely on the perceived benefits of e-cigarettes, people should avoid smoking altogether.

In April, the U.S. Food and Drug Administration (FDA) approved a new screening test for colon cancer, making it the first blood-based test for this type of cancer. While this test does make it more convenient for people to get screened for colon cancer, it is also less exact than the current screening methods. It is important to discuss your risk factors and screening options with your doctor.

It appears people with the highest levels of physical activity have lower rates of cancer of the esophagus, lung, kidney, colon, head and neck, rectum, bladder and breast, compared with people with the lowest levels of physical activity.

A group of scientists wants to develop technology to create a synthetic human genome, which could lead to improved organ transplantation, vaccines and medicines, and to new ways to fight cancer and infections.

It appears that four healthy habits—getting 150 minutes of moderate-intensity exercise per week, maintaining a body mass index between 18.5 and 27.5, no smoking, and drinking only in moderation—may prevent many cancer cases and death in white people.
