The key to eradicating tumors and preventing relapses and metastasis is buried within the tumor itself. The tumor cells themselves contain a sort of needle in the haystack. Just 1% of the total volume of the tumor is responsible for reproduction, and a targeted surgery or drugs could be sufficient enough to “deactivate” the tumor and avoid any possibility of a reoccurrence. This type of treatment could possibly change the therapeutic approach to malignant tumors according to an Italian study at the Superior Health Institute (ISS) by Professor Ruggero De Maria, the Director
Dr. Karen Aboody estimates that she has cured several hundred mice of a cancer of the central nervous system called neuroblastoma.
First she injected them with specialized neural stem cells that naturally zero in on the tumors and surround them. Then she administered an anti-cancer agent that the cells converted into a highly toxic drug (…)
For 3 1/2 years, the agency focused on the basic groundwork needed to someday use human embryonic stem cells to replace body parts damaged by injury or disease. Such cures are still far in the future.
Now the institute has a more immediate goal: boosting therapies

Dalhousie Medical School cancer researcher Dr. Patrick Lee has proven that a common virus can infect and kill breast cancer stem cells. This breakthrough finding is published in the current issue of Molecular Therapy, the journal of the American Society of Gene Therapy.
It is only within the past few years that the scientific community has understood the full significance of cancer stem cells and the urgent need to find a means of eliminating them.
“Cancer stem cells are essentially mother cells,” explains Dr. Lee, Cameron Chair in Basic Cancer Research at Dalhousie Medical School. “They continuously produce new
Scientists at the University of California have found a potential new use for human embryonic stem cells: helping cancer patients recover the cognitive function lost when their brains are treated with radiation.
People with tumors in their head or neck often undergo radiation therapy after the cancer is surgically removed. Radiation helps kill malignant cells left behind. But it also can debilitate the hippocampus, the brain region responsible for learning, memory and processing of spatial information.
The researchers wondered whether embryonic stem cells could pick up the slack.
So they radiated the heads of 18 rats. Two days later, six of those
Former Hollywood producer Dominick Dunne died at the age of 83 after a long battle with bladder cancer. In past year he traveled to the Dominican Republic and Germany for stem cell treatments.
In the past year, Dunne had traveled to Germany and the Dominican Republic for experimental stem cell treatments to fight his cancer. He wrote that he and actress Farrah Fawcett were in the same clinic in Bavaria but didn’t see each other. Fawcett, a 1970s sex symbol and TV star of “Charlie’s Angels,” died in June at age 62.
