Jack Nicholson has been serving up a steady stream of cheer for cancer patients at the Cedars-Sinai Los Angeles hospital.

The Hollywood icon and Oscar winner has been visiting terminal patients and cheering them up with jokes, card games, and behind-the-scenes stories about his career.

Nicholson's next career move comes in the form of a movie called The Bucket List. He plays a dying man in the film and began spending time at the hospital to research his role. But once his film finished, Nicholson kept visiting. He was that touched and moved by the patients.

Hospital staff say the actor's visits do wonders for the patient spirits. The only down side is for Nicholson who finds it hard to leave, knowing he may have seen some of his new friends for the last time.

A study appearing in the Journal of Clinical Oncology reveals there may be something out there that can extend the lives of patients with recurrent prostate cancer.

This something is a new class of anti-cancer targeted drugs that scientists at Cedars-Sinai Medical Center in Los Angeles say are quite promising, despite their ineffectiveness in some prostate cancer patients with no previous chemotherapy treatment.

Pertuzumab, a molecular targeted compound that has been used successfully in ovarian cancer patients, has been shown to block the human epidermal growth factor receptor family by binding to and inhibiting the function of HER2 receptors. They essentially block a key pathway that leads to cancer growth. And this blockage can possibly offer a better, longer life for recurrent prostate cancer patients whose diseases no longer respond to traditional chemotherapy.

Pertuzumab, marketed under the brand name Omnitarg by Roche and Genentech, is just one of many targeted cancer therapies that give researchers hope that cancer may one day be a lifetime disease that can be skillfully managed.

Nearly a decade ago, women in Long Island began to worry about their high rates of breast cancer. So they advocated and lobbied and pushed until a public law was passed that allowed for the creation of the Long Island Breast Cancer Project. Funded by both the National Cancer Institute and the National Institute of Environmental Health Sciences, great data has emerged from this project -- like the data linking breast cancer and household pesticides.

Although much research has linked cancer with pesticides in work and industrial settings, few studies have investigated what these chemicals can do in households -- until now, thanks to research conducted as part of The Long Island Breast Cancer Project.

Published online in the December 13 American Journal of Epidemiology, researchers found an association between lifetime residential pesticide use and breast cancer risk in a sample of 1,508 Long Island women diagnosed with breast cancer between 1996 and 1997. These women were compared to 1,556 random controls. All women were asked to self-report their pesticide exposure and to offer blood samples for the study of organochlorine compound levels -- found in lawn and garden products.

As expected, researchers found an increased breast cancer risk for women whose blood samples showed the highest levels of organochlorine compounds. They also found it hard to find women who did not use lawn and garden pesticides to some degree.

Use of household pesticides has infiltrated our society, says researcher Susan Teitelbaum, assistant professor in the department of community medicine at Mount Sinai School of Medicine in New York, who reports she is happy to see a movement toward use of alternative methods, like integrated pest management.

Teitelbaum has just one recommendation as result of this study. It's quite simple really -- stop using pesticides.

Just days before the 5th anniversary of the September 11th tragedy, Mt. Sinai Medical Center released a health report on the variety of illnesses suffered by rescue workers and city residents who were present at the scene. A class-action lawsuit has been filed against NYC by 8,000 of these workers who blame the toxic atmosphere and lack of health warnings from city officials for the onset of cancers, respiratory and gastrointestinal diseases developed after exposure to the site.

The toxic metals and particles floating in the air above the pile of rubble that day are the same toxic elements found in cigarette smoke -- and these particles became deeply embedded in rescue workers and volunteers lungs. A special warning has been issued to those present at the site to now quit smoking, to avoid making their symptoms worse.

NY senator-D Hillary Clinton, along with other state representatives, are urging more federal funding for health care for these individuals. The new study has also helped establish new guidelines for the diagnosis and treatment of 9/11 related illnesses. As many of the volunteers and crisis workers now live in other areas of the country, the guidelines provide much needed understanding of their ailments to unaware doctors.
