A major problem with standard chemotherapy is that is goes everywhere, harming many normal cells and causing serious side-effects. For years, researchers have been looking for ways to deliver the drugs directly to cancer cells. A new approach not only targets the chemotherapy drug, but adds in another way to kill the cancer cells. The approach is very clever and exciting, but a bit complicated

More and more evidence supports the role of obesity as a risk factor for many cancers, including cancers of the breast, colon, kidney, and ovaries. There is good evidence that prostate cancer can be added to that growing list. Researchers may now have identified how obesity influences the development of prostate cancer (and maybe others).
The prostate gland is a small, walnut-size organ

Globally, more than 1 billion people use tobacco products. Smoking is the single greatest risk factor for cancer, and cigarette smoke contains over 5000 different chemicals, many of them cancer causing (carcinogenic). Some of the chemicals in cigarette smoke are known to directly cause DNA damage - the same mutations found in cancers caused by tobacco products. The indirect effects of smoking include changes in the activity of genes in cells exposed to the chemicals in smoke.
To examine the effects of smoking

Many cancers are caused by exposure to chemicals, like those found in cigarettes, or by radiation, mostly from the sun. What is becoming increasingly clear is that infections with viruses, bacteria and parasites are responsible for a large percentage of cancer cases. Recent research showed that, worldwide, infections were responsible for 16.1 percent of cancer cases reported in 2008. This amounts to about 2 million of the 12.7 million new cases that arose in that year.

The influence of cancer cells on their neighbors is something that is being actively studied. In this research, human prostate cells were exposed to arsenic, a chemical known to cause cancer. Arsenic is a relevant chemical to study because it is a common contaminant in drinking water around the world. The prostate cells exposed to arsenic turned into malignant cancer cells.
The arsenic-transformed cells were then placed in culture near (but not touching) normal prostate stem cells.
