Upon moving to San Francisco, Tropp settled near Chinatown. Eventually, she was contracted by
James Beard to write a cookbook:
The Modern Art of Chinese Cooking: Techniques and Recipes in 1982. In 1989, she appeared on
Great Chefs. The
China Moon Cookbook was published in 1992. The
New York Times called it "one of the first books that successfully brought together Chinese and European-American mainstream cooking." The book was awarded an
International Association of Culinary Professionals Cookbook Award. In 1994, Tropp's sister, Nhumey, called her to tell Tropp that their mother had died of
ovarian cancer at the age of 48. Prior to this, they did not know what kind of cancer their mother had died from. Nhumey had researched medical records to find the cause of death. Due to concerns about ovarian cancer being passed down genetically, Nhumey had a
oophorectomy and it was confirmed she had ovarian cancer. Tropp also had an
oophorectomy and it was also confirmed she had ovarian cancer. Tropp had
chemotherapy for one year coupled with Chinese medicinal and herbal treatments. In 1996, she sold China Moon due to her declining health. She also took time off from writing. Tropp eventually stopped her Western cancer treatments when her cancer was in remission. She continued to use medicinal Chinese treatments. While in Asia, with her husband Bart Rhoades, her cancer returned. Back in California, she started chemotherapy again. ==Later life and death==
