Cancer blog: I manage the cancer blog with lots of help and support form other bloggers. Through this cancer blog my friends and I try to bring stories of hope for patients with cancer. The cancer blog often republishes important blog posts from other cancer related blogs at Medicineworld.org. If you are searching for a blog that covers wide variety of cancer topics, this may be the one for you.

Breast cancer blog: Breast cancer blog is run by Emily and other bloggers and they bring you the latest stories, news and events that are related to breast cancer. Increasing awareness about breast cancer among women and in the general population is the main goal of this breast cancer blog.

Lung cancer blog: Lung cancer blog is managed by Scott with the help of other bloggers. Through this blog Scott and his friends constantly remind the readers about the dangers of smoking. It's a never-ending struggle against this miserable disease with which a social stigma of smoking is associated.

Colon cancer blog: Colon cancer blog is run by Sue and other bloggers. Sue brings a personal touch to the colon cancer blog since her mother died of colon cancer few years ago. She writes about stories, research news and advances in treatment related to colon cancer.

Prostate cancer blog: Prostate cancer is the most common cancer among American men. American Cancer Society estimates that over 230,000 new cases of prostate cancer occur in the United state every year. This important blog about prostate cancer is run by Mark and other bloggers.

Chinese Remedy For Breast Cancer


Chinese Remedy For Breast Cancer
A derivative of the sweet wormwood plant used since ancient times to fight malaria and shown to precisely target and kill cancer cells may someday aid in stopping breast cancer before it gets a toehold.

In a new study, two University of Washington bioengineers found that the substance, artemisinin, appeared to prevent the onset of breast cancer in rats that had been given a cancer-causing agent. The study appears in the latest issue of the journal Cancer Letters.

"Based on earlier studies, artemisinin is selectively toxic to cancer cells and is effective orally," according to Henry Lai, research professor in the Department of Bioengineering, who conducted the study with fellow UW bioengineer Narendra P. Singh, a research associate professor in the department. "With the results of this study, it's an attractive candidate for cancer prevention".

The properties that make artemisinin an effective antimalarial agent also appear responsible for its anti-cancer clout. When artemisinin comes into contact with iron, a chemical reaction ensues that spawns free radicals -- highly reactive chemicals that, when formed inside a cell, attack the cell membrane and other structures, killing the cell.

The malaria parasite can't eliminate iron in the blood cells it eats, and stores it. Artemisinin makes that stored iron toxic to the parasite.

The same appears to be true for cancer. Because they multiply so rapidly, most cancer cells have a high rate of iron uptake. Their surfaces have large numbers of receptors, which transport iron into the cells. That appears to allow the artemisinin to selectively target and kill the cancer cells, based on their higher iron content.

In the latest study, the researchers administered to rats a single oral dose of 7,12-dimethylbenz[a]anthracene, a substance known to induce multiple breast tumors. Half of the rats then were fed regular food, while the other half were fed food with 0.02 percent artemisinin added. For 40 weeks, researchers monitored each group for the formation of breast tumors.

Among the rats that didn't get artemisinin, 96 percent developed tumors. In comparison, 57 percent of the artemisinin-fed rats developed tumors.

In addition, the researchers report, tumors that did develop in the artemisinin-fed rats were both "significantly fewer and smaller in size when compared with controls".

The reason for artemisinin's apparent preventative effect may be twofold, the researchers said. The substance may kill precancerous cells, which also tend to use more iron than ordinary cells, before those cells develop into a tumor. Artemisinin also may impede angiogenesis, or a tumor's ability to grow networks of blood vessels that allow it to enlarge.

Because artemisinin is widely used in Asia and Africa as an anti-malarial, it has a track record of being relatively safe and causing no known side effects, Lai said. "The present data indicate that it may be a potent cancer-chemoprevention agent.

"Additional studies are needed to investigate whether the breast cancer prevention property of artemisinin can be generalized to other types of cancer".

Chongqing Holley Holdings, a Chinese company, and Holley Pharmaceuticals, its U.S. subsidiary, supported the research. The company, located in Chongqing, China, has been in the artemisinin business for more than 30 years and is a world leader in farming, extracting and manufacturing artemisinin, its derivatives and artemisinin-based anti-malaria drugs.
