When Professor Jane Plant was first diagnosed with breast cancer at age 42 she was devastated. With two young children and her life ahead of her, cancer hit her like a ton of bricks. Five years later her cancer returned and again, it returned. It seemed that radiation and chemotherapy just weren't working for her. And then it all changed when according to a report in the Telegraph, seen on Natural News, she began to take her life into her own hands. Plant researched why the instances of breast cancer at the time were so much lower in China (1 in 100,000 versus 1 in 10). Please note that today this statistic has changed dramatically which is the possible result of China adopting a Western culture. Today, about 45 out of every 100,000 women in Beijing have the disease.
She realized that the main difference in their diet was a lack of dairy and an abundance of cancer-fighting vegetables. With that she gave up dairy and loaded up on vegetables. Her tumor disappeared and no cancer has returned since 1992. Her book, Your Life in Your Hands details her life saving diet.
This is in no way meant to be a doctor's advice but it's quite a story and she's not the first to tell it. According to Phyllis A. Balch and her book Prescription for Nutritional Healing:
The American Cancer Society estimates that of the 500,000 cancer deaths that occur in the United States, about one-third can be attributed to dietary factors, with another third being caused by cigarette smoking.
