X-Files and Californication star David Duchovny recently announced he had entered rehab for sex addiction. He has asked for privacy at this time, for him, his children and actress wife Tea Leoni.

So leaving that aside - what exactly is sexual addiction? Is it even a legitimate disease?

Sexual addiction is described as

"behavior of a person who has an unusually intense sex drive or an obsession with sex. Sex and the thought of sex tend to dominate the sex addict's thinking, making it difficult to work or engage in healthy personal relationships.

A recent report from the National Cancer Institute suggests that older women who are over weight increase their risk for breast cancer. The study looked at the health histories from nearly 100,000 postmenopausal women and examined their change in weight, or body mass index (BMI), over their adult lifetime.

Women who were not obese or overweight at age 18 but were at ages 35 to 50 had almost double the risk of developing breast cancer compared with women who maintained a normal weight, according to a Science Daily report on the study.

"Only a third of patients with breast cancer get to discuss their breast reconstruction options with their general cancer surgeon before the tumor is removed," claim researchers in a University of Michigan study described in HeathDay News.

Clinical scientists at the University of Michigan Comprehensive Care Center interviewed 1,178 women recently diagnosed with breast cancer to see if reconstruction was suggested as an option to them.

Scientists are working on ways to target smaller amounts of radiation to the tumor cells in breast cancer patients. This approach could improve the outcome of radiation therapy by shortening treatment times and minimizing the exposure of healthy breast tissue to damaging X-rays.

Many studies demonstrate the value of exercise in everyday life, but exercise during breast cancer therapy may make a difference too.

Studies published in the Journal of Clinical Oncology suggest that physical activity positively affects patients’ self esteem, body conditioning and ability to complete chemotherapy treatments. This helps patients endure and benefit more from their therapies.

Women who get breast cancer before the age of 40 tend to develop more aggressive tumors that are harder to treat. Using chemotherapy in some of these younger patients, however, may not provide much benefit to their survival, according to a study from researchers at Leiden University Medical Center in the Netherlands. Opting for other treatments, such as those that stop tumor cells from responding to estrogen may end up being more effective for this group of patients.
